shorepower

The MultiPlus 12/2000/80-50 has a minimum shore power limit of - 4.5A according to minimum shore current limits 07-2019.xls which I downloaded from victron. When I set the CCGX to 4.5 and exit the menu, the value pops back up to 8.5A. Why might this be happening and how can I get it to 4.5Amps? I also tried to set it via a bluetooth smart dongle. Same behavior.

Could it be that the rating/spreadsheet is not for North America at 120 Volts and only 4.5A for 220V? That would really be disappointing and should probably be mentioned on the spreadsheet. Also I can't turn off power boost, I need it.

Thanks!

Hi, I've tried to word this question several times and never get an answer. I'll try again.

I have 3000/12/120 (230) MP connected to 400ah lithium bank and 2000W Isolation Transformer.

I'm getting an issue with high loads (well within the limits) when on shore power (I have the multi control limiter set to 8.0A to be conservative).

So for example 9 times out of 10 when the kettle (2000w) is turned on it's fine. However every now and then you see the red overload light flash and I get an email alert via VRM emailed to me.

I've tired with shore power off and never get this on just the inverter alone, so I think there is an issue with power assist, but no one can confirm or deny that, so I'm a little stuck.

Planning long term cruise on the boat, so don't feel happy with this - even though I won't be using shore power much. I would like to know the MP has no gremlins before I set sail.

Hope someone out there can help with this!

I've checked all of the maximum power inputs on my appliances and the highest is the microwave oven that can pull 2600W. I think the max peak on the MP is 6000W, so with shore power on I don't see why I'm getting this over load warning.

Regards,

Michael

i have one quattro 8Kva, with AC-in-1 connected to shore power, AC-in-2 connected to a generator.
By default they transfer switch, preferring AC-in-1.

But would it also be possible to have it combine the inputs and sync?

Hi all

I have a system setup on my boat where I have shore power coming in via onboard MCB (16A) and a RCD type C as specified in the Victron instructions. The earths are in separate terminal, so I’m separated from the shore earth. Then wired directly to the AC Input on the Multiplus.

After installation I plugged in the AC from shore and everything was fine but after the first time I disconnected I have a strange phenomenon where I have a RCD trip either in the shore supply system or the one installed before my inverter AC input every time I plug into shore power. At first I thought it was because there were another RCD type C in the shore supply so tried to Bypass the one installed onboard but with the same result.

I found a procedure that worked for connecting to shore AC supply but I does not seem right that I have to go through that every time. The procedure is as follows:

-turn off the main 12V distribution switch

-turn off my multiplus on the front or via remote

-turn off the AC output loads via the AC out MCB/RCD

-Pull my main 12V system fuse (125A) out

-then in able to connect the shore cable, turn the inverter back on, insert the main 12v fuse and reconnect the 12V and 230V loads from the distribution panels internally.

I can’t get my head around why this happens?

anybody have any ideas?

Hi Everyone - I'm hoping you can help with a question I have on the best choice of AC>DC charger, and the setup for my planned battery configuration in my van build

At the moment I have three 95Ah AGM batteries that are hooked up in parallel that i want to charge using a Blue Smart AC>DC charger from my shore power system, and i'm wondering whether it's best to go with the 30A single output charger, with the pos and neg going to the batteries at the opposing end of the parallel bank, or potentially go with the 15A 3 output charger with each battery having its own pos connection and the neg's all running to a common bus bar? All options with fuses at the battery end of course.

Are there any benefits or drawbacks to either approach?

Does anyone have a similar setup to either option and can provide any good feedback on their choice?

Thanks!!!

Kyle

Hi Community,

From the factory, the boat was originally equipped with AGM only, and the house was powered from one of the starter banks (dual purpose AGM). This will only allow my appliances to run for 12 to 24hr, so I have ordered an upgrade to Lithium. The original shore-power charger is connected to 3 independent AGM banks (Starter 1, 2 and thruster). The charger does not have any more independent outputs.

The yard is currently fitting the boat with 2 x Orion Smart DC-DC charges (+ MPPT 100/30, Cerbo GX, smartshunt +++), that will be connected from each Starter-banks and to the new Lithium house bank.

So my question is; if I use Volt sensing on the DC-DC, will the DC-DC charge the Lithium's when the Shore-power charger is charging the Starte-batteries (@14,4v)?

Will this work? Any major issues with this idea?

I know this is not the best set-up, but I would like to leave the original set-up as original as possible and rather add a Multi-plus inverter/charger for the Lithium bank next year.

PS!! the original shore power charger is a 20A Cristec Y-power 5-step charger.

Need some advice on my setup please. The system consist of the following:

2- 48v 3kVA Quatros

50 amp 120/240 Split Phase Shore Power

7,500 Watt 60 Amp 120v Single Phase Generator

Cerbo and a bunch of solar ect...

The system is configured in 120/240 split phase with the shore power L1 going to the master Quatro AC-2 input and L2 going to the slave Quatro AC-2 input. The generator simply goes to AC-1 input on the master Quatro with nothing connected to the slave Quatro AC-1 input. This setup works fine but its a little lacking when running the generator when the batteries are low. I never see much more than 3,000 watts from the generator and the batteries don't see much of a charge when the slave Quatro has a load on it. This causes the generator to run hours on end not charging the batteries. Spending 12K on a new 240v split phase generator is out of the question. We need to keep the split phase for the 240v appliances onboard. Will a Victron auto transformer between the generator and inverters work for me? Or maybe two transformers so I can stack the inverters.. One after the shore power, 240v to 120v to stacked Quatros and then another transformer to get split phase off the Quatros. Any advice would be great thank you.

I labelled my Quattro AC input 1 as ‘shore power’, then set up an alarm rule on my CCGX where all input labels (not available, grid, generator, shore power) were enabled.

When I disconnected my shore power, the CCGX and VRM gave me ‘grid lost’ alarms. I acknowledged the alarm on the CCGX and reconnected shore power but it took a reset to clear the CCGX, and I can’t clear it on the VRM.

I’ve tried deleting the rule and setting up a new one, re-labelling my input as ‘grid’ to see if that’ll clear it - no luck.

Any advice appreciated - would like to clear from the VRM.

Hi All,

I am designing my electrics for my van. There is already a 230V AC, shore power, network in my van. I would like to add a 12V circuit for off-grid circumstances, for charging laptop, running lights and a fridge. I would like to mainly charge this battery with 200/300W solar power via the SmartSolar MPPT XX/XX charge controller. But I think it would be beneficial to also be able to charge it via shore power if solar power is no option. Would it be possible and safe to charge the 12V battery (AGM Deep Cycle 250Ah) using a laptop charger plugged in my 230V AC network connected to the SmartSolar MPPT XX/XX charge controller? I would add a breaker between my solar panel and SmartSolar controller and solder a plug on my old laptop charger to easily connect it. This way I don't have to buy a separate 230/12V charger.

Thank you for your help and advice!

Hello everybody,

I have 3 x 12V 95Ah AGM's in parallel and plan is to charge the bank with Dolphin charger when connected to shore power.

Which of below modes you'd choose for setup? If I got it right, "Calcium lead" mode would have the right voltages? I'm planning to use one of the posts of charger to connect the starter battery which is a traditional 12v battery so it would need the "Wet & flooded" option but which one you see would be a best option for this combo with 3 AGM and one wet battery?

Cheers, Mikko

I believe my RV's Victron setup has FIVE major components:

• MPPT (1)
• MPPT (2)
• SmartBMV monitor
• Color Control GX
• MultiPlus (the big unit, inverter)
• In addition, 4 x 100ah Battle Born batteries

In this RV, we also have an Onan 5500 generator (45amps) and when connected to shore power, has always been 50 amps. (We are configured as a 12v system, not 24v, in case that's a question one might ask.)

Frequently, when putting a heavy load on the power consumption (two good examples are the electric/hydraulic slides and extending (sometimes retracting) the hydraulic leveling jacks), the system will reboot. So far, we have only seen this on generator and/or shore power.

Reproducing the scenario is easy: While still plugged into shore power (or have genny on), retract slides or jacks. In addition, the generator will shut off if in use during these reboots. (The Victron system doesn't engage the generator, that's the RV's house "OneControl" system.) I think because the OneControl system is also rebooting, that is what kills the generator. (The Onan's have some weird "pulse" on/off system, and I don't have the gizmo that lets me wire that up to the Victron system.)

I have found that simply unplugging from shore power (or turning off the generator) and running solely on batteries usually prevents the reboots. Bear in mind that there are no A/C's on, no heaters, and minimal power consumption as we are either getting setup in a campground or preparing to leave.

Our sorta-vendor (not original installer, but did some fixes for us) doesn't have any clue why this might be happening. One would think that the 50amp shore power would be more than sufficient to be handle these operations. We do NOT have reboots even when running three air conditioners!

During the last time we experienced this, and I had disabled shore power to run solely on batteries, I watched the BMV while extending the jacks. The voltage did slip down to around 11 volts. The reboot doesn't happen, as I said earlier, when on batteries alone. The system did NOT reboot, however.

Does anyone have any suggestions as to what I can look for as a potential cause of this issue.

Hi,

I have purchased the following devices and I am starting to setup the system on my Boat, where I have a Starter Battery and a House Battery:

• Blue Power Charger 12 30 3
• Smart solar MPPT 100 30
• Orion-TR Smart 12 12 - 30
• Smart Battery Protect 12/24 100
• BMV-712 Smart
• 2 x Victron 12V 175W Mono Solar Panels

My question relates to situation in which these devices will all be working at the same time.

The AC/DC and DC/DC Charger, will rarely do that, as I will either be on Shore Power or on Engine Power, but there could be very rare instances of the engines being run while on the dock for a few minutes when also still connected on Shore power.

My main concern is the MPPT Solar Charger running at the same time as the DC/DC Charger when under way and in daylight. But technically, if I am in the situation described above at the dock, all three chargers could be working at the same time, for some short period of time.

Can this damage the devices or the Battery? At present the Battery is a AGM 100Ah Deep Cycle but I will soon be replacing it with a LiFePO4.

Can someone please recommend the best way to setup this system? Am I better off switching manually things on off based on the usage? Or can I setup the devices parameters in such a way that they will automatically stop working at the right time based on the voltage produced by other devices?

I would appreciate some guidance and help.

Thank you in advance,

Adri

Hi everyone,

My first posting and wonderful to have such community and help! I am new to van life, and I am working on getting a Sprinter van battery house (Chinese lithium batteries: 8 cells @ 3.6V 280Amp) which will give me 560Amp 12V house bank. I would like to be able to charge my house batteries while driving (using the Sprinter alternator battery), and also while parked in my garage or campgrounds using AC plug. I don't plan on using solar. I like what i have read so far about Victron products, and I would like to know what will be the best package to order and install (there seem to be many products and options doing the same thing: i.e. the Multiplus vs EasyPlus, etc. I plan to have a small induction stove (1200W), small portable 120V air conditioner (6 Amp), and the Bosch electrical water heater (120V, so these would be my three 120V AC load. Any advise is greatly apprecaited.

My system is on a boat with a MultiPlus Compact 12v/1600va/70a and a digital multi control panel.

I have 4x175w Victron PV panels connected to a Victron 100/50 MPPT controller.

My understanding is that both the multiplus and the mppt are both charging the battery bank simultaneously whilst connected to shore power. Can I turn off battery charging on the multiplus so that batteries are charged only using the solar power via the mppt?

I need AC shore power whilst in the marina so can’t turn the multiplus off completely.

Hello everyone,

the manual states(Multiplus 48/3000), that the Phase from the Grid should be connected to the Phase-In from the Inverter. Due to the mobile usage of the Inverter, the Inverter shall be connected to the Grid with a Schuko plug https://upload.wikimedia.org/wikipedia/commons/thumb/2/23/Schuko_plug_and_socket_annotated.png/240px-Schuko_plug_and_socket_annotated.png. However the right plugging of the schuko plug is not always ensured, because you can plug the schuko plug in two ways (Not turned Phase to Phase, and turned Phase to Neutral). Does somebody know a device, that stops the current from follwing when the device is not connected properly?

How can I disable MPPT going into Bulk in the morning when my boat is connected to the shore power and the batteries are at Float level kept by the AC charger? Thanks.

Hi,

i have a Multiplus 12/3000/120 setup inside my van. Everything works fine. The System is connected to shore. The Battery is fully charged.

Now i connected an electrical heater (2000W) to the system. The heater is the only thing connected.

Usually the Heater should consume around 2100W. Connected to the Multiplus it doesn't use more then 1700W and the heater isn't getting warm as usual. The Multiplus is in Absorption mode. If i disconnect my shore cable, the consumption is around 2300W and the heater is getting warmer and blows faster. The MultiPlus show inverting and the Battery gets empty (as expected ;) )

Any Ideas why the heater is getting less power on shore connection?

Max. shore Current Limit is set to 16A/230V. Charging the Battery (additionally to the heater) with 1200W works fine. All in all providing at least 3200W from shore is working fine. VRM shows 8A usage when heater is connected.

But the heater is working with less power.

Does someone has any good idea belonging to this strange behavior?

thanks!

Having a problem connecting shore power. I have a multiplus 3000 120 16 together with 100/30 and 100/50 smart mppt with a Cerbo gx. When I connect the ac in it throws the main beaker on the dock. Tried not connecting the earth...same. If I disconnect the ac out all works good and charges my batteries. Now the weird bit. With the shore power disconnected the inverter powers the whole boat without a problem. Any ideas?

Hi,

I have a setup with the Cerbo GX, ET112, BMV712 and a Quick 12v battery charger in a boat. I have the ET112 in-line on the shore power to monitor load. No inverter or Victron charger in the setup by now.

On the GX I can see the ET112 and the power passing through it, and it reports itself as grid. Is there any way I can change this to shore and configure an alarm/notification if disconnected?

My Multipass 24/3000 was installed this past summer. Everything has been great until two weeks ago.

Recently, I went to use my boat and after unplugging from shore power, engines start etc. I noticed the breaker for the inverter was not illuminated, but the breaker was on and had not tripped. Before starting the boat, AC/DC panel showed inverter breaker operating and illuminated. The inverter is left in charge only when connected to shore. The color control GX showed no alarms or issues.

With the engines operating the port side steering was not functioning but starboard size was. (Boat uses jet drives with buckets and joystick steering). After a few minutes trying to trouble shoot, I started the generator and then the breaker switch for the inverter became illuminated and now both port and starboard steering began to work.

The alternators on both engine were replaced during the Multipass install and everything had been working without issue.

Summary: the Multipass 24/3000 only is working when connected to shore power or receiving generator power source. It does not work when the engine is running.

What am I missing that may cause this?

I have 2 x 200ah lithium batteries from victron.... they charge through a multuplus 12/3000 on shore power and typically charges fully in 90 min or less.

Now my batteries and multi aren't "activating" when the shore power is on..... is this temperature related? It just got to freezing temps around my area, the batteries on the app say they are at 50° +.....

In the settings for the batteries it looks like this

[image]

Its approx 40° outside......

Any help appreciated. The system worked well for quite some time, only the ambient temps have changed so I'm curious if my settings are wrong or if I simply need a battery warmer of some sort....

I want to add on my Caravan a Solar Panel. Actual is build in a Blue Smart IP65 Charger that charges a 50Ah AGM Batterie. For charging with solar i bought a BlueSolar MPPT 75/15 Charger.
My Question, can i connect the MPPT Charger parallel with the Shore power Charger direct on the Batterie?

Hello all,

I have a Multiplus (V476) connected on a Cerbo (V2.6)

No alarm after 5 seconds of loss of shore power

But if I configure the AC input for Grid, it works!

Thank you for your help

I am in the process of a new install. I have wired up the system for Shore power. I have not yet connected batteries to the Victron Mulitplus but would like to test the AC portion of what I have connected so far. Is it OK to plug-in shore power and turn on the Victron to test the AC portion of the circuits without the batteries connected or will the Victron error out and not pass the AC.

So a 50amp RV shore outlet is actually two 50amp connections for a total of 100amps right? So when I program my multiplus inverters, is my input current limit 100amps meaning I program 50amp or is it 50amp and I program 25amp? Or am I totally misthinking this because it mentions "per phase" and a parallel system is single phase so I should just set it to 100amp... or is that 50amp...

I'm following the following information from the Parallel and three phase VE.Bus systems document

The following settings need to be made in the master of each phase:

• Inverter output voltage

• Input current limits
  (the effective input current limit is the setted limit multiplied by the number of units per phase. For example, setting a 10A limit with VEConfigure in a system with two units per phase results on a 20A limit for that phase. Being able to set a different limit per phase allows for maximum configurability.

Also when I'm looking at the maximum charge current, if my total charge limit is 70amp I would set it to 35amp?

New to the group. To lay the groundwork for the question:

• We have a 50 amp fifth wheel.
• We bought the unit used from a private seller, very happy overall.
• The solar / Victron was installed by the seller or he had it done.
• We have 4x Battle Born 100ah LifePo4, 4x 190W solar panels, 2x MPPT, SmartBMV and the Victron 12/3000/120-50
• We (the wife, the dog and I) are fulltimers, three months now!

We have been, in the past three months, mostly on shore power, and always on (confirmed) 50 amps. We found that one of the monitor panels (not listed above) showed us at 30 amps continually. Reached out to seller, he indicated that if I had the inverter on, I'd be limited to 30 amps. Turned it to Off, and I'm back to 50 amps and I can run the air conditioners. Excellent for the Texas heat we'd been dealing with.

Two days ago, we relocated to a park, and were fortunate enough to park in the shade. Sure, solar will be very much reduced, but that's okay: we have 50 amps.

Tonight...the generator kicked on. Turns out we ran down the batteries to 50%. Direct DC usage in the rig, like lights, whatever else is straight DC, ran them down. With the Victron set to off, the shore power doesn't recharge the batteries. If I turn the Victron to just "Charger" (not Inverter), it will recharge the batteries, but I will still be limited to a 30 amp system.

This feels wrong to me. I'm a programmer, have been for 30 years. I'm decent at debugging, but I haven't examined all the the wiring and gotten a deeper understanding of the layout. It just feels wrong that it's this way.

When we have good sun, the batteries always get charged up the next day, even on cloudy days. We've been here, in the shade, for... two full days, I think.

I'm trying to determine if one or more of the following are true:

• Is this a standard solar implementation scenario? That there is only ONE possible charger/converter to replenish the batteries installed at one time?
• Is there a possible wiring / schematic / system design oversight or bug. (I don't have a schematic yet, I have reached out to get one, if available.)
• There would have been an original charger/converter installed on the rig, before the Victron, etc. was installed. Does anyone ever have that still wired into the system?
• Really, my only choices are "have sun" or "be limited to 30 amps even when 50 amp shore power is available"? This cannot be right.

I'm trying to determine that, if the Victron being on limits me to 30 amps, is there a different way to charge the batteries when on shore power? I know my question might be difficult to many without y'all knowing more about how it's wired up. But I'm hoping I kept my questions as free of the implementation as possible and focused on generalizations, and typical scenarios.

For the moment, there's a chill coming into the area tonight and I don't need two A/C's. I'm okay with the 30 amps for now, and I'll get my batteries replenished. Not a long term solution.

I truly appreciate any help anyone can put forth, or any education I can glean out of your answers. I did do extensive research into solar, DC, AC, converters/chargers, inverters, MPPT, etc. before we bought the rig. I feel sort of comfortable in my general knowledge. I was a little sad I didn't get to do the install myself so I'd REALLY know it, inside and out, but the deal was just too good to pass up and our seller was a pleasure to work with. But I lack the intimate knowledge that installing it myself would have gained.

Thanks in advance for any assistance.

My Motorhome Question

Will I damage my Multiplus if the battery is disconnected while the multi is connected to shore power? I'm thinking of a weird use case where I've either switched off the battery disconnect switch or somehow my battery cable came loose.

Hi,

I'm looking to install a multiplus 3000 on my yacht, i see there are 2 outputs from the unit, does anyone know if they can be configured so that one of them is only active when connected to shore power or the generator?

My calorifier and battery chargers are currently on the circuit that comes from the gen/shore power so i don't want the inverter to be putting power out on the 2nd output when i'm just on batteries.

Hope that makes sense....

I just purchased a Catamaran that is setup on 220 50hz. Aircon, water maker, hot water heaters are all 220 50hz. I have the following:

I plan to upgrade to 1200ah or 1800ah lithium batteries.

Based on what I have read it appears there is no way to convert 60hz to 50hz with these devices.

I was thinking of replacing my inverter with 1 Victron (maybe 2 stacked) inverter(s) and run all AC loads through them and add a separate charger or 2 that run off shore power or genset. The idea would be never run all Aircon at same time unless plugged in to shore power or the genset is running. I know there will be losses with AC to DC to AC. What I don’t know is what impact this setup can have to batter life if you assume never discharge bellow mfg recommendations.

Is the above a bad idea?
