After only 6 weeks my 5kVA Multiplus II has failed!!! My installer has taken the faulty unit into the distributor who has submitted all the warranty info. The disappointing thing is the time this all takes and so far I have no idea when a replacement will be coming. It is kind of critical when you are relying on power. Can this process be streamlined, maybe have a swap out or something similar?

Also, I have heard that the Multiplus II is not as reliable as the Mulitplus. Is this true?

I have 2 multiplus connected to rv 50amp 240 but I have a onan generator 5500 120v. A trasnfer switch is installed and the shore power goes to a transfer input , the generator goes to the other power input and the output to the panel.But when i look at other wire diagrams it dont seem right. also can I run power to the multiplus and t-tap off to the transfer switch that way the multiplus doesnt have to be on to power up the rv when plugged in.

I have a narrowboat with a bank of 5 leisure + 1 starter batteries (110AH)

I have a 15yr old Victron charger that appears the same as a Phoenix. I've read an article in a reputable magazine that states that when I'm connected to shore power I can leave the charger on all the time to keep the batteries in good condition. I'd like this to be true as the boat is left unattended for weeks at a time but I'd like some confirmation.

I woke this moring to find the Overload, low battery, high temp lights on. Plus the float light is also on. None of the faults are taking place now. Its possible battery was low in the night. I have disconnected all inputs and outputs to see if it will reset, but it has not. Does nybody have ideas on what to do about it please?

My solar solar panels were supplying 443 watts of power and my fridge was drawing 297 watts. My 4 battleborn batteries (400 amps) started the day at 100% and was dropping rather than maintaining the charge. It seems that when the inverter is on (victron 3000/50/12) the solar panels using a victron smart solar charger 100/50 does not charge the batteries or contribute to the power being pulled. However with the inverter off the solar panels charge the batteries just fine. If anyone is familiar with this problem I'd appreciate some feedback.

Thanks in Advance!

Hey All,

I am currently having a problem with a Multiplus Compact 12/2000.

A bit of the installation:

It has been working fine since 2012 until now.

We are using a Multiplus Digital MultiControl

There has been no changes done to the cabling.

The Issue:

230V input connected to Shore.

Inverter Mode on:

The unit will turn on, go to Inverter mode as requested. After, it will sense the input AC. After 30 seconds (roughly), the voltage sensing relay will latch the bypass and will start charging the batteries.

All good for now, but after 5 minutes (not exactly, varies), the unit will go to inverter mode and won't charge the battery. It looks like the input AC has been lost, but I have wired in parallel a tester and it shows constant 220-230V 50Hz, even when the system does the changeover. After a while it will read the mains and charge the battery again.

Same happens with the "charge only" mode.

"Charge only>Blue LED "Mains On" blinking>"Mains On" LED permanently on/Bulk charger amber on>split second changeover to inverter, then goes back to charger with 220V Out.

After 5 minutes, charger will shut down and a bit later, it will turn on by itself.

It is a constant on/off.

-I tested the mains

-I have unplugged the Temperature Sensor after checking that the temperature is low.

My conclusion is that there is something wrong with the charger and not an external power source. Could you guys tell me if there is anything I should look into?

Hi all, I am new to all this inverter stuff, I bought a second hand Victron Phoenix compact multi 12/800/35 at a good price. Would anyone have a guide on how to use and setup? I would like to connect a 300w solar panel to the inverter with two 100ah batteries to run some small tools in my shed and a laptop. I don't know anything about this inverter and if it is even working, I did connect a small 12v 7ah battery to see if it would power on. When I press the on switch the green Led light for 1 or 2 seconds and then goes off and the Red alarm Led comes on. Please, would someone send me a link or something like a setup user guide and wiring positions? It came with a plug and a 2-foot length of cable connected to AC in, and a long ethernet leads a small control panel. I don't know where the AC out connections are. Sorry but I am a Victron Noob. So be gentle. Thanks

I have 4x 100Ah AGM batteries as service batteries in my boat, in a 12v system, There are however 3 different charging inputs. No. 1 Via the engine (80Amp engine alternator to a Victron 100-3 Battery Isolator to the service batteries main switch to the service batteries). No. 2 Via a Victron IP22 12v 30/3 battery charger. No. 3 a 100W Victron solar panel with a Victron MPPT 75/15 solar charge regulator. In normal circumstances, all 3 charge inputs would not be on together, but usually it would be a combination of No. 1 and No.3 or a combination of No. 2 and No. 3 and at night just No. 2 when connected to 220v shore power.

One conclusion that could be drawn is: I like Victron products!

But, I find it very difficult to determine all the setting for the BMV700 as well as the MPPT solar monitor in regards to charge voltage, absorption and float voltage and some I don´t understand at all, i.e: bulk and absorption time limits (MPPT monitor values) and is the MPPT monitor maximum current, the same as that of the BMV700? I find the Victron manuals very limited in that respect, hence I revert to this forum

Thank you,

Marco

In a rapidly changing technology with new equipment entering the market every other day surely some form of qualified tech support is vital?

Victron, as far as I have discovered, relies on the generosity of existing customer, who are not necessarily expert, or its dealer network who are of widely varying knowledge and who's primary concerrn is to sell equipment.

Other than the stalwart efforts of the Victron Community Manager there seems to be no way that reasonably critical questions can expect expert response in a reasonable time frame.

Am I missing some further level of support escalation or should I just stick the wires where I think they should go and hope I'm not going to blow things up and presumably void my warranty?

I have just installed a Victron bmv 712 unit in my boat. Setup for house and started battery banks. The display shows voltage of main and auxillary batteries, but is giving a fixed amp and watt reading, both positive and both excessive, I have worked the setup program and consulted the manual, making sure all functions are turned on. I tried the synchronize and zero calibrate functions on both the head unit and phone and they do nothing. I did this with all input power shut off, batteries fully charged. Then applied fridge & other components to see the draw...no change. ie. it is not reading current or power. I tried reversing the negative battery terminals on the shunt...no change.

I see others have had similar problems but do not clearly see the answer. Is this a defective unit? Surely not the cable. I have not taken a photo of the shunt installation but will attach soon.

Thanks.

Please i need an explanation as to what VE.bus inverter state "255" mean and also what MPPT state "131" is?

My multiplus compact is going straight to passthrough instead of going to charge mode. The batteries are not fully charged, so I think it should go to bulk. If I reset it,it does goes to bulk.

Hi everyone, would any of you know where I could get the correct Mosfet for Victron Phoenix compact multi 12/800/35?

The number on the burnt-out ones seem to be 1G01S8-N304AP, I can find Mosfet N304AP, but none with the full number. I don't know a lot about this sort of stuff, but I know I could resolder new ones if I could get them. I bought the unit second-hand none working, and I want to see if I can get it working again, I only have a couple of 100w solar panels at the moment and a cheap inverter, so if I could get this good brand name working it would be great. Any help would be great. Thanks, guys.

Hi all, does any body know if Victron have made stencils for Visio for their Victron Products?

Or if any body else made it and made it free to use.

It makes lite so much easier when making my schematics.

Hello, I have a victron smartsolar 100/20 and I connected an inverted on load output. It's a 500w inverter that I used on my previous charger. I know that load is limited to 20A and that my inverted is oversized but it's not a problem as there are only a few lights connected to the inverter.

Bad news is that my inverted can't start when connected to load output of the victron.

The inverter works correctly when connected directly to the battery. Is it normal or is there a defect on my device ? I tried to start the inverter only without anything connected to it but it's doesn't work either.

Invertor keeps shutting down as per link .... there is nothing attached to charger side ? Anyone explain ?

My 702 voltage reading for both house and Auxiliary voltage reads more than 1 volt higher than my voltmeter shows. 702 readout = 12.82 voltmeter read out = 12.69 My fuse in the wires that run from the battery to shunt is 100 m amp. Can you help me fix the problem?

Last week I purchased two Solara 55watt solar panels and a Victron Smart Solar Controller 75/15

My boat is a Swan 46 with a 24 Volt electrical system. I wired the panels in series as indicated in the Solara instructions in series per the 24-volt diagram.

The controller shows a high voltage alert and indicates about 45 volts at the controller (which makes sense - 2 panels at roughly 22+ volts each). A voltmeter confirms the 45 volts.

Is there a setting or something I need to do at the controller to regulate the voltage for my 24 volt system? Or, are the panels simply the wrong voltage to charge a 24 Volt system?

Thank you in advance.

I have a 200w solar panel connected to my pwm light 12v 20a and it was working fine. The light was flashing indicating power coming from the solar panel and into the battery but now the solar input light is showing nothing even though I know there is 19v coming from the solar panel. At one point the battery did run flat and I thought maybe it turned itself off so I disconnected it and reconnected the cables and still nothing. When change the setting I get an 'ff' flash after the setting has been selected. Not sure what this means as it is not in my one page instruction sheet I got with the controller.

Hi, apologies in advance for the all the scatter gun questions!

Hopefully someone here might be able to help me to size and choose the right equipment for a bill of materials.

I know what they say about assumptions but, let us assume that I need to operate consuming approximately 27.5kWh.

Our energy supply costs for the year are on track to come in at £30K+ per annum, at least whilst we continue to consume nearly all of this power direct from the grid. With that in mind we need to design and build an energy storage system that would help to reduce this particular operating cost significantly.

Based on my research to date I seem to be on the right track, but given the likely sum of our intended investment I would like to make sure that I am not undersizing or oversizing (or going wildly over budget!)

The intention is to scale up to generate and provide up to a 15kW input from renewable energy (wind/solar/biomass). But would this be able to provide enough charge assuming I can consistently supply the 15kW, whilst consuming 27.5kWh?

I read somewhere that there is usually a need to respect a 40/60 ratio in charge vs consumption, but if this is incorrect then someone please correct me! :) Also do Li-ion batteries allow for a much better performance in this respect?

Anyway, I am looking at the Victron Quattro 48/15000-200-100/100 15KW off-grid solar to run alongside a suitably sized battery bank (vendor/size suggestions welcome).

So, is this a wise product choice, and would we be able to run on continuous mains power via the Victron Quattro + battery bank storage for our power needs, until we have all the other RE components in place?

Many thanks!

Greetings to all.

I have on board a Victron Centaur 24v/80A charger charging a bank of 2x2 12V/225Ah lead acid batteries. Recently the batteries started to heat and loose water, when I went to diagnose I found out that the charger is outputting 29.8V regardless of dip switch setting. I found that there is a potentiometer inside and tried adjusting that but I could only reduce the voltage to 29.6V with strange pulsing noise from internal SMPS like it is running on minimum pulsing. I cannot leave the charger like this,it will destroy the batteries. Did someone encounter a similar problem? Is there a solution or should I just buy another charger? This one is about 4yrs old so if its gone already I think I will consider another brand. The one I replaced lasted over 12 yrs. Oh,I tried replacing the batteries with another bank new batteries but the charger is still outputting 29.6V.

does the victron 702 measure the % of , house, starter, or both ? also I have a new renogy solar controller and the two %od batteries, don't jive, the renogy solar panels controller only goes to the house side while the victron is wired to house and starter

We have a Multiplus 12 3000, 120 230/240 volt Victron inverter charger on our 52 foot motor boat. We overloaded it and it shutdown. When we restart it the inverter light comes on and the low battery light comes on and then the low battery light flashes, and then the inverter side shuts down but the charger side shows lights on as though it is working, but it's not. We've checked external fuses, battery terminals and can't find anything wrong. We've spoken to the guy who installed it and he suggested we check everything with the multimeter, which we have done, and everything is fine and the batteries are fully charged. DOn't know what else to do,

regards Anna and Gary

I just wanted to provide a success story, and a shoutout to Victron. Thanks for making an amazing product, which has proved invaluable in our bus conversion.

We had gone back and forth about installing propane heaters/cooktops, and even considered a diesel (webasto) cooktop. When considering an electricity-based system, we considered how to limit electrical consumption, as well as which appliances or features we could live without.

We also considered several cheap inverter products, but finally invested in a Multiplus 24/3000-70-16, with a Venus GX and a BMW702. Our battery is a 200ah Lithium pack, and this is installed in our 13 meter touring bus conversion, coupled to the bus alternator via a charging relay.

In the end, we decided to just go all in - 100% electrical - and have wired all the following on the AC1 output:

- 1Kw Split system Air Conditioner (Heat Pump/Inverter)

- Dual-zone Induction Cooktop

- Full-size Microwave/Grill/Convection Combo Oven

- Full-size Refridgerator/Freezer combo

- 7kg Washing Machine

- Outlets for all kinds of tools/accessories, such as heatguns, hairdriers, hair straighteners, vacuum cleaner, computers, etc.

- Electrical Hot Water heater (on AC2), which also can be connected to the engine coolant/webasto).

We are literally still on our maiden voyage, and have visited several campsites across Europe. The ability to use PowerAssist is especially amazing, since several campsites only provided 10amps or even 6 amps of 220V service. So even with only 6Amps available shore power, we had full AC running, while cooking pizzas in the convection oven, charging our DC system (lights, kitchen fans, water pressure pump, etc.), running the fridge/freezer, and vacuum cleaning, all at the same time.

The greatest part was how we completely "forgot" about being on the road - the Victron setup gave us the freedom to cook, work, clean, and basically operate like home, without ever having to worry or consider any electricity limitations.

So thanks again for a fantastic product (and community) - the Multiplus has taken what we anticipated to be stressful and a big headache, and turned it into a completely worryfree experience.

Hello - I have a system with 3 x 5KVA Multiplus which has been running great for couple of years - suddenly the Virtual switch is not working - any ideas? - I haven changed any settings - except after I found it not to work I changed a few values just to see if any change

So, this happened a couple of hours earlier. Nothing changed in regards to connections.

It just stopped charging. All settings are as they’ve been for the past year or so. Charger swaps between bulk and absorption every few minutes, but there is no load going into the battery.

Solar voltage going up and down according to irradiance, but current stays at zero.

Any ideas?

For my DIY powerwall project I can buy a hardly used Quattro 48/5000/70. Sadly the seller cannot show the device in a working setup, The story is that the new Quattro was changed some years ago for another system/brand. After sitting on a shelf for some years he now whats to sell the Quattro.

Anyone tips on testing a Quattro that is not in a working setup? Or is it a big gamble?

Howdy,

I'm testing a Victron 200Amp 12Volt battery.

Starting voltage was 12.8 volts (all cell voltages within .04).

Connected a 4 amp load.

After 8 hours, battery voltage was 12.52 (all cell voltages within .01).

7 hours later, battery cut off, and Bluetooth page displayed.....

--- Hardware Failure alarm ---

--- Internal Communication Failure ----

An external meter reads 9.25 volts....

Any suggestions on what we do next ???

Thanks DennisB

My new 76 w solar panel dose not deliver the expected amps. My victron 75/15 with Bluetooth show 0.3-0.5 amps current in sunshine. I see i forgot to moove the jumper, might this be the problem? How do I reset the whole thing?

Will my readings from the Bluetooth Victron 100/30 be accurate if the battery system that it supplies is at 100%? It seems to produce near capacity AmpHrs when the battery is charging, but cuts back in similar conditions when the battery if fully charged
