configuration Multiplus 24/3000/70


We have deployed two solar trackers with different solar panel technologies installed. Each technology is attached to a MPPT150/35 or 250/60 charge controller. A set of 2x4 Hoppecke batteries in parallel is loaded by the current coming from the charge controllers. The batteries are then connected to the inverter.

As long as the Multiplus is not connected to the grid it works fine. The problem comes when I do connect the Multiplus to the grid. The grid charges the batteries and stops the load from the charge controllesr, even if the batteries are fully loaded.

My question is: is there any specific configuration to enter in the Multiplus via VEConfigure3, such that the Multiplus switch to the grid for a low charge of the batteries and switch back to batteries when those reach a min load?

Many thanks for your help

Victron/Simpbms/Tesla Setup Van build


Starting a new van build and have some questions regarding battery setup.

I have 1 Tesla model s module (might upgrade to 2 in the future), I'm using Victron Buck boost dc dc 100a for alternator charging and a Mltiplus 3000w inverter.

For BMS I want to use the SIMP BMS together with a Victron gx type, this is where I have some questions and in need of some tips.

Anyone in here that uses a similar setup? Experiences?

Do you use contactors, precharge contactors as fail-safe system or Victron battery protect?

Current sensor via simp bms or victron battery monitor?

Charge enable/disable for temperatur high low, any way to trigger a heating pad?

Anyone tried simp with the cerbo gx?

A lot of questions here. Not much info on the simp bms/victron setup.

we have a customer requesting a solar system for oxygen pumps in his fish farm, he has 4 oxygen pumps each of 2.2 kW rated power and they are three-phase he needs to operate them 24/7 there is also grid in the site for 8-10 hour per day and there is also a generator, he wants to operate using solar during the day time and about 2 hours battery backup at night or during a cloudy winter day, and the Genset will start when the batteries are empty and there is no grid.

can we offer him a solution with Victron at this big back-up capacity, also note that there is no suitable place for the battery so we have to create a small cabin and cool it with a small 12000 BTU AC

I thought of :

19.44 kWp solar (54 panels 360 watts divided for three sets each 18 panels for each inverter)

3 x 5 KVA Quattro

3 X 250/100 MPPT charger (1 for each inverter)

24.576 kWh battery ( 12 X LiFePO4 Battery 12,8V/160Ah Smart ) considering 85%DOD


1- can this combination (especially the inverter) stand the starting current of this load ( I don't know the starting current the pumps are installed and I couldn't find their datasheet online but I attached the nameplate photo)

2. can I replace the batteries with LONG LIFE GEL OPZV 2V with considering 60% DOD, will they stand the discharge current of the load since the load during the battery back up?

- I attached the load calculation and the motor nameplate

ESS with external control and 3PH Multiplus, sometimes ignoring setpoints

All, i have a new victron ESS with pylontech and 3x5kw Multiplus, plus (independent) production.
For several reasons i want to control the system externally.
Nothing connected to the power output. No meter connected.
This works well most of the time, and the actual power reported on "Grid Power (modbus regs 820..) is closely matching the setpoints set via MQTT and validated by reading from (vebus ID) registers 37,40,41.
However, there are times where the multiplus seem to do what they want. I might give instruction to charge the batteries with 4kW each, but one of them "produces" and the battery discharges ..
Often in that situation also the "AC Input" tile does only show a bar and no more data.
I have to say i have some 5kW+ water pumps which may kick in and stop at any time, which is of course not a really stable load .. as they are (like everything) on the "grid" side of the inverters, this is handled by the public grid, providing power until the multipluses eventually provide the power.

- Are there any accessible registers which i should look at in this situation ?
- is there a limit how often a setpoint update should happen - over MQTT, over Modbus/TCP ?
- how fast will/should the Multiplus usually switch from new setpoint to "do" what is asked for ?
- from charging the battery to generating output power ?
- from 4kW charge to 1kW produce ?
- anything i have wrong in my thinking ?
Happy to get some logs, showing the modbus read responses on the AC Input vs Setpoint values, where one can see that they seem to be "disconnected", at other times, they are following by few W ..

Inverter/Charger selection for pure Off-Grid/MicroGrid/Island setup


i plan to move to a complete decoupling to the public grid (microgrid/off-grid/island) in a 3-phase configuration. The basic power and battery requirements are known and i could use the Multiplus 48/5000 or the Multiplus II 48/5000 or the Quattro 48/5000 - but which of them is best suited in this mode ? Any special feature at the AC-In line does not matter (there is no public grid) any PV and other genset are connected to the AC-out. Running ESS configs in the past with both Multiplus variants shows that the MultiplusII fans are more or less always running which was not the case with the Multiplus - which is not critical but worth mentioning. Because both Multiplus variants are still on sale, i'm curious to understand the pros and cons for my planned off-grid configuration. Any advise/comment/experience ?

Active AC Input disconnected AND high voltage alarm daily

So any constructive assistance will be highly appreciated. I have researched this fault numerous times now and also looked across many forums, but I seem to not be able to diagnose and correct these errors.

Background: I have a Multi 2 5000 connected to Cerbo GX with 250/100 MPPT and BMV 702 connected to a 120Ah lithium bank that has its own BMS (so a dumb lithium essentially).

Problem 1: If anything happens to the Multi and I have to restart of switch off or update ESS settings on VE Config I cannot get the Multi to accept AC input voltage. It reads the voltage and displays a nice 233V on AC-in L1 but Active AC Input shows Disconnected. When i turn on the system it goes through the following steps:

I switch the switch to position 1 and soon after the Inverter On comes on and then one hears a internal relay switching a few times. Then after 30 seconds or so there is a loudish click and inverter switches off, after a minute it switches on and process repeats. Eventually it stays on but Main On does not come on and I have no AC input to the system.

This is now the 4th time this is happening to me and it seems to have come right on its own somehow the last few times. I suspected corrupted firmware and reloaded it via VE Config the last time and when I looked again it was working. Co-incidentally the problem occurred while I was downloading the VE Config file to make some charge voltage changes (this coincidence is just too big)

What info do I need to post here to clarify this issue?

Problem 2: Every day I get a high voltage alarm on my BMV. Also I noticed the alarm when I was busy trying to restart my system from the AC input issue.


My settings are as follows:

BMV (Battery)

Capacity 120Ah
Charged Voltage new 56.8V (old 57.6V) (3.5625V/cell) {58.4V (3.65V/cell)}

Exporting power to the grid.

Hi Everyone

I want to add a Multiplus-11 GX 24/3000/70-3 to my current system in order to export power back to the grid when I have excess. I have a 150/70 MPPT Charge controller and a Multiplus Compact 24/1600/40-16 (which the GX will replace) connected to my 550amp/hr battery bank. The 24/1600 is connected to the grid so that I can charge the batteries after several weeks of poor weather in the winter. Will the Multiplus-11 GX automatically export back to the grid when the batteries are full and no loads are being used ?

I don't know if the 24/1600 can export back to the grid already, maybe it can?

I live in Perth Western Australia.

Thanks in advance.

3 phase unbalanced load - no distributed neutral

Apologies in advance if this question has been answered somewhere else.

Please see attached diagram.

I have a customer that wants to operate CNC engineering equipment from a stand-alone supply. My question is regarding the equipment loading on the Quattro's. The CNC Mill has only a 3ph 3 wire connection to an onboard 400V to 200V transformer which also only has a 3 wire output. Assumption is a delta-delta connection as drawn.

I'm at saturation level with 3ph AC theory and understand what happens at the load end of the unbalanced 3 wire load but I can't find anything that explains how a single inverter in a 3ph config handle returning unbalanced current from the other two lines.

My questions:

Will this work?

If not, what would be needed to make it work?

Is this kind of connection supported by Victron at all?

Any thoughts and recommendations greatly appreciated.

ESS System Phase Compensation Help

i installed 3x MP2 3000VA /48V. Updated Firmware to 2629474. made ve quick config, setted all settings. made the ess assistant in each MP. Now i try everything but the whole system acts like phase compensation is disabled although it is enabled. each inverter does only deliver so much power as required on the specific phase according to the grid meter. No idea why the compensation setting in the venus gx is not working. Please help!!

AC L1,L2,L3 is connected to MPNr.1-ACIN, MPNr2-ACIN, MPNr3-ACIN. The system is useless. If the electric car is plugged in on one phase with 7kW it only delivers max. 2.4kW from one inverter, if no other loads are switched on. If someone cooks on L2, i only get 2.4kW from the inverter on Nr.2.

I read all installation manuals, the training video on the Victron professional side, there is no hint what is wrong, looks like a software bug on the Venus gx!

Under voltage alarm on only Quattro not on BYD


I had multiple Undervoltage alarms/warnings on L1 Quattro in 3 phase setup out of sudden.

The LOG file shows BYD reporting normal 54.7 V voltage There was a normal load on the system and no overload recorded. The alarms were getting triggered randomly and the log shows wildly fluctuating VE bus voltage

Does the Ve bus take the voltage only from L1 Quattro?

I checked cable tightness in Quattro ( all three phases ) as well as on the LYNX busbar.

Will check later today the breakers and the individual battery module tightness. What else should I check? The system worked for the last 1 year without any major issues.

The system is ONgrid /ESS with 10 KWH BYD pro and 3 ph 5 KVA Quattro with 6 KVA Fronius and 250/70 Smartsolar

Inconsistent energy production and consumption readings

We're working with a couple of systems where the production and consumption readings in VRM don't really make sense - namely, for a given period, kWh consumed far exceeds kWh produced. I'd love to get a better understanding of what might be going on.

The composition of both systems is as follows:

  • Three-phase off-grid systems with PV + battery + genset
  • Battery inverters (6x): Quattro 48/8000/110-2x100 rev2
  • MPPT charge controllers (3x): SmartSolar Charger MPPT 250/100
  • PV inverter (1x): Fronius Eco 27.0-3-S
  • Diesel generator

The issue is that in the kWh Excel report (and also in the VRM UI), it appears that the energy delivered from the batteries is far greater than the energy going to them.

Example over a 30-day period:

  • PV to battery: 908 kWh
  • Genset to battery: 87 kWh
  • Battery to consumer: 1575 kWh

It's not clear where the extra ~600 kWh come from. It's obviously not just additional discharge of the batteries, which have a capacity of ~100 kWh. Also this kind of pattern – of consumption being greater than production – is repeated on a daily basis; i.e. it's not just a one-off data glitch.

Any ideas what the culprit might be? And in the meantime, any thoughts as to whether the production or the consumption values are likely to be more reliable?

Finally, besides the two systems that exhibit this issue, there is a third with the same composition, where the readings there appear to be more consistent. In that the energy delivered from the batteries is 70-80% of the energy going into them.
