Shore power limit on MultiPlus Compact 12/2000/80-50 120V keeps setting itself to 8.5 Amps

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.

Multiplus Intermittent Overload alerts on shorepower

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.

Multiplus shuts down while plugged into shore power on “charge only” mode

I have a Victron Multiplus Compact 12/2000/80 inverter/charger.

I use it in my travel trailer with solar panels and battleborn batteries.

I wired the inverter’s “AC out” into the trailer’s breaker box and the shore power cord on the trailer into the inverter’s “AC in“ in order to take advantage of the built-in automatic transfer switch.

I only plug into shore power when I need to use the trailer’s air conditioner. When plugged into shore power, I switch the Multiplus to “charge only” mode as my battery bank and this Multiplus will not power the air conditioner if shore power is lost. It’s start up requires around 4,000 Watts.

However, sometimes when I’m plugged into shore power, the Multiplus will turn off for a few seconds, killing the AC power, and then turn back on again even though shore power was not lost.

This is inconvenient when trying to sleep as I have to jump up and turn off the air conditioner before the Multiplus turns back on and is suddenly tapped for the large load required by the air conditioner. This results in a loud buzz from the Multiplus and the error light flicking on for a second before it returns to normal functioning.

I’m guessing this happens because the Multiplus has parameters to shutdown temporarily when the shore power current, voltage, and/or frequency drops below a certain amount—something one would not notice if the shore power was not entering the trailer via the Multiplus. I do understand these parameters are in place to protect whatever load device you have plugged in, but for me, it’s a inconvenience.

I’m wondering if there’s a way to change these parameters in order to prevent this from happening.

Please point me in the right direction so I can fix this. I have the VE bus. If you could help me with this, I would be very grateful.

Thank you,

Shore power RCD trip multiplus 12/1600/70 (Boat)

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?

Victron Blue Smart IP22 Bluetooth Battery Charger setup for parallel batteries

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?

Charging the Lithiums using a DC-DC charger, Connected to AGM batteries connected to Shorepower Charger?

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.

Split Phase System Configuration Advice

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.

VRM grid lost alarm will not clear

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.

Is it possible to use shore power as input for a SmartSolar MPPT charge controller to charge 12V AGM battery?

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!

System Reboots happen under certain circumstances...

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.

How to setup multiple chargers connecting simultaneously.


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,

MultiPlus 12/3000/120-16 - Low Power on absorbtion/float


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?

Multipass 24/3000 shuts down when disconnected from shore power

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?

Setting up Parallel Multiplus for a 50Amp RV all documents are very imprecise...

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?

Victron 3000, 30 amps vs. 50 amps, Shore vs. Solar, Batteries not charging when off, of course

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.

Boat setup so there are no issues with shore power 50hz or 60hz

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:

*Magnum inverter/charger model MS2712E (2700W inverter at 12V)
* Silentwind 400w wind gen connected to a Wind Controller - 12v Max Current Wind 40A/Solar 20A
Max DC output 2x10A
* 2 Victron MPPT 150/85-Tr SmartSolar charge controllers
* 4 LG315W pannels
* Batteries - 4 Lifeline AGM 210Ah

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?
