Multiplus2/Bluesolar limited/throttled solar production


2 x Multiplus ii 48/3000/35-32 in parallel

1 x Bluesolar MPPT 150/70

8 x Trojan T125

18 x Renesola 300w panels 6 strings with 3 panels per string

Running ESS feeding excess to the grid.

I started off with 1 multiplus and 9 panels with average output as per graph.


I then upgraded with another 9 identical panels. The output was capped at just over 2kw.


And after adding another multiplus it is now capped at 3,6kw from 10am to 2pm.


Thinking that the inverter current is derated due to temperature as the internal fans switch on at 09:30 in the mornings already with room temperature between 20-23 degrees C, I have installed 2 120mm ac fans on each inverter and another one on the mppt ducting air into the bottom intakes. Before the mppt was almost hot to the touch, and now cool after installing the fan from 10-4pm. The fans made practically no change to the solar output.

MPPT current at the peak readings is 108V and 33A that is just over 50% capacity. At 3,6kw production the inverter is running at exactly 60% of the rated output. Any suggestions as to why production is limited or capped?

Multiplus II GX control charging current with analog input


I want to control the charging current of a multi2 GX 48V 3000 with a analog input .

I have allready a ESS system and want to add this feature Ladestromsteuerung.

I have a external current sensor - it deliver 0..2,33 V acording the power of a PV inverter.

I want to reduce the charging current of the Multi - if not enough power comes from this PV.

For 2,33 I want maximum , for 0V I want minimum DC charge current


I have measured the voltage is comes to the Multi but if I activate the Assistant for charge current - the battery is not charged anymore.

If somebody has a idea how to make it work - would be great.

[Multiplus II 48/5000 (240v AC)] AC In (grid) limited to 1.8kW in 'Inverter' mode (ESS Mode-3).

Hi all,

I recently got ESS (Mode 3) working on a MultiPlus II 48/5000, with a 300Ah LiFePo4 pack.

I'm able to control the import and export (setting AcPowerSetpoint through MQTT, topic W/<VRM_ID>/vebus/261/Hub4/L1/AcPowerSetpoint).

However, I've noticed that the import/export from/to the grid (AC In) is limited to 1.8kW, when charging or discharging. This limit isn't there when in Passthru mode.

Some examples:

'Maximum import' mode (i.e. full charge):


AcPowerSetPoint: 6000.

Expected: AC in would ramp up max rate service AC out load and to charge batteries with remaining power.

'Maximum export' mode (i.e. full discharge):


AcPowerSetPoint: -6000.

Expected: AC out would be serviced by the batteries, while AC in would ramp up to max negative value (export), supplied by batteries (-100A on batteries). I've observed this -1.8kW Grid value, even with low AC loads value (~0.6kW), but don't have a screenshot at the moment.

Maximum import rate with full AC out load:


AcPowerSetPoint: 6000

Observed: AC out is at max load (cooker, kettle, other loads on) for a limited time, at ~6.3kW. AC In is limited to ~1.9kW, with the 4.9kW being supplied by the batteries.

Expected: AC input would go to maximum to supply the AC loads, with any excess going to charge the batteries.

Here's more details of that instance, from the VRM portal:


Passthru mode, high AC out load:


AcPowerSetPoint: not being set (so not actively controlling setpoint). The AC in (Grid) isn't limited to 1.8kW here.

Here are the firmware versions installed:

MultiPlus II: 475

Venus GZ: v2.58

Is there a setting I've misconfigured that's causing this behaviour (1.8kW limit in AC in, when in charging/discharging a.k.a 'inverter' mode)?

Many thanks and Kind regards,

Multiplus entering power assist unnecessarily; draining batteries

The power system (components listed here; all devices have the latest firmware as of this posting) I installed in my fifth wheel is entering power assist mode despite the AC input being less than the input current limit. For background, one goal of this system was to be able to run a pair (15 and 13.5 kBTU/hr) of air conditioners on 30A/120VAC single phase service, with the inverters/batteries supplementing the grid power for intermittent loads like a Keurig, microwave, etc. The trailer came with one air conditioner on L1 and the other on L2. Of course, when only single phase input is provided, the second inverter inverts from 12 VDC but its continuous output must of course be limited by the first inverter's charging capacity of 120A. After conversion losses this is inadequate to power the second AC without pulling from the batteries (side note for any Victron employees lurking: *please* implement a way for the second inverter in a split-phase system to accept AC input that's in-phase with the first inverter! This is obviously something that can be done in software and its absence is driving customers with RV applications out of their minds). To get around this problem I installed a 20A switch that allows me to switch the second air conditioner from L1 to L2. I thought that was clever.

But not really; the stubbornness of the Multiplus defeats my ingenuity. See pics below.



As you can see, it is drawing well below the input current limit from the grid, yet "assisting" and drawing down my batteries. The total draw is around 28-29A although it can't be seen in the pictures (but you can infer it from the "AC Loads").

Please help me figure out how to force the inverter to draw up to the input current limit before it goes into assist mode; I really can't stomach the thought that I paid ~$15k and put in dozens of hours of work to actually lose capability.

Edit: The system is plugged into a 30A 120/240VAC split-phase connection. Inside the rig I have a 50A breaker upstream of the Multis, and I cut the little metal link joining the two poles of the breaker so that I can switch L1 and L2 on/off separately. In the example above, L2 is cut off to simulate how the Multis behave when only given a 30A/120VAC input (the first inverter switches to grid input while the second simply inverts from the batteries, as I ranted about in bold above). It is connected through several long extension cords, hence the voltage drop. Nevertheless, there is sufficient input amperage available to power these loads from grid input alone (and it certainly should be pulling more than 23A when it has a 30A input current limit).

Here's a VRM link:

And here's a link to the RVMS file with the current inverter configuration:

Pylontech Charge Current Limit

I have 3 Pylontech US2000 Plus connected in parallel with a MultiPlus 48/3000/35 and a MPPT 150/45.

The CCL is set at 30A by the battery, is this because the MultiPlus can only charge with 35A and the battery knows this? I haven't connected the PV panels yet but when I do should I see this value raise to 75A as the MPPT can provide an extra 45A?

The DCL is set to 75A so I'm assuming that all 3 batteries are being detected and everything in the setup is fine. Any comments welcome please and thank you.

Sustain current too high?

Hello Victron fellows,

I have set some Li ion with Victron inverters, always for self consumption with PV inverters, but this one is cracking me up. This system consists in three 48V Multiplus II 3000/35 as a three phasic system, and an ESS assistant is set. The sustain voltage is 43V and cuttoff around 42V. The modules have a low SOH, but the system should work anyway. It charges and discharges correctly, up to the point where my BMS disables allow to discharge at around 48V, because there are low cells (it should discharge to less than 42V if it was good).

Then, Sustain mode is active and the current goes UP TO 90A. Of course when this happens the voltage raises quickly, the allow to discharge comes on again and it goes to Discharging mode. Repeating the process endlessly - Even without PV POWER, that means it consumes a lot of power.

My question is, why does it go up to 90A, since sustain mode should be 5A per unit and how can I solve this?

Thank you very much!

How to Limit DC-DC Charger Current on Orion-Tr Smart?

Hey Victron community!

First time posting here, so forgive me if I'm missing any formalities.

I recently bought a Victron Orion-Tr Smart DC-DC Charger Non-Isolated 12/12-30. We are planning to use the charger in a travel trailer with a custom 300ah battery bank. The problem is that we want to wait to upgrade the OEM positive wire from the tow vehicle's battery (it is currently a 10awg wire) to a much larger wire until after we start using the trailer. Per my research, we will need closer to a 2awg wire, which is much bigger and a pain to re-route from the tow vehicle, so hoping to kick the can down the road a little.

With that said, is there a way to limit either max current or max power output on these units? Or is the only way to limit it via limiting the voltage? Are there any tricks to artificially limit the current?

Thanks in advance!

Multiplus 24/5000/120 settings: search mode, max charge current, input current limit


I have the above Multiplus, BlueSolar MPPT 100/30, 2x200W/12V serial PVs, 2x200Ah/12V serial AGM batteries, Honda EU2200i generator and have the following questions about three settings:

1. If I have both the search mode and AES switched on, which is over-riding the other or can they work together?

1. For the 400Ah/24V battery set it doesn’t seem possible to set the maximum charge current as low as the generators continuous output 1800W/230V=7,8A. The lowest setting is 25% of something (percentage of what is still unclear? Maybe 100A x 25% = 25A?).

3. The input current limit can only be set to the following values:6,3A (1.4kVA at 230V),10A (2.3kVA at 230V),12A (2.8kVA at 230V),16A (3.7kVA at 230V),20A (4.6kVA at 230V), 25A (5.7kVA at 230V),30A (6.9kVA at 230V), 50A (11.5kVA at 230V). The question is how this setting affects the charging on different loads. It is clear that I should not have this setting to more than the generator’s continuous output power. But is it so, that 1) at no load the genset is charging with current of the setting (e.g. 6,3A), 2) when there is load up until the setting (6,3A), the load will be supplied 100% by the genset and the rest is used for charging and 3) when the limit setting (6,3A) is passed then the load will be covered by the genset AND the batteries and no charging will happen?

DVCC doesn't seems to work?

I've charged my batteries to 100% today, which triggered BMS to stop further charge, but Multi is not stopping, DVCC setting is enabled, BMS is sending all limits to VenusGX correctly, but it looks like Multi is just ignoring it. My DVCC settings are as below:


Battery is 100% charged, BMS set the charge current limit to 0.0A, but multi is still pushing nearly 1A into the batteries:


My system is VenuxGX (with ESS Assistant) + Multiplus II 48V/3000VA + AC coupled PV + Liion batteries with Batrium BMS (connected to VenusGX via CANBus)

I've also noticed that the same thing is happening when BMS is forcing limited charging mode (battery nearly full, CCL set to 0.5A), the Multi also is not limiting power to the set current:


Is that normal??? Am I missing something? Shouldn't Multi limit the power to the set value or I just misunderstood this function?!

Blue solar 75/15 charge limit

I want to use a blue solar 75/15 to power a load at a max current of 10 amps, ie constant voltage. Ideally don’t want it to charge my battery with the unused power as that is dealt with by a different, bigger blue solar Array. The load will not always be as much as the power available, array is only 100 w, ie not enough for 10 amps..... although I could add a second 100w.......
basically it will be connected to an elec distribution board, that powers all the loads and has its own battery charge algorithim. It also has a display showing all battery voltages/solar currents etc, so I wanted to use it to control and display that stuff and charge the battery.
so, if I connect the load only to the 12v distribution board will that do the above, or does the battery connection also need to be used. I assume turning charge off stops all power, as limiting charge current limits charge and load?

Or any other ideas?

I purchased a Victron SmartSolar MPPT 100/20 Charge Controller. I am having a problem with the charge controller cycling the load "On" then "Off" then back "On".

Description of failure:

1. The charge controller will show that the load is set to "On".

2. A 12v fan is connected that draws a max of 9W of power or a car cell phone charger is plugged in (without the phone connected or charging)

3. The charger controller will show that the load is turned to "Off"

4. Have a pause for 1 to 2 seconds

5. The load will then be turned to "On"

Notes: The charge controller never shows a voltage below 12.6 volts from the battery so I know that it is not pulling a large load from the battery.

I don't see how a 12v phone charger without a phone connected could be tripping the 20A capacity of the controller.

AC input current limit setting is very different from where it actually limits.

Got a Quattro 12/5000/220-2x100 120V running firmware 2733430. (Same system as in this old post.) Since then, I've beefed up the shoreline to a true 20A circuit, and adjusted the input limit to 20A accordingly.

Sometimes the system will happily draw 19.8A from the shore, and sometimes it'll limit itself at 11.6A and go into PowerAssist for my roughly-2kW load.

Here's the weird thing: If I increment the input current limit just a little, the actual power drawn from the shore increases dramatically. Here's my observational data:

Current limit set in VEConfigure Actual current drawn Load and status
20A 11.6A 2kw, PowerAssist assisting
21A 12.6A 2kw, PowerAssist assisting
21.5A 20.2A 2kw, battery charging
22A 20.7A 2kw, battery charging
30A 27A 2kw, battery charging

AC input voltage is roughly 108-112V in all cases.

So why the huge jump in actual current, for a tiny bump in the set limit? It's not correlated with input voltage, and I can't identify anything this behavior is correlated with. I've tried setting WeakAC and it had no effect on the behavior either way. Shore power is 60Hz grid AC, so it's not like a generator is lagging its frequency or anything. What else should I be checking?

For the moment, I'm leaving it at 21.5A to keep the battery from draining while on shore power, even though it slightly overdraws the circuit's nominal rating, the breaker doesn't actually trip until a bit higher than that. ;)

Phoenix Multi Compact 12/800/35-16 Overload Warning and Low Battery Alarm

Dear all, we have recently bought a Multi compact 12/800VA together with a SB SUNLIGHT AccuForce 12V - 150Ah Solar VRLA Battery in order to replace an ONLINE UPS in a on-Grid Photovoltaic 500kWp installation. The system works in 12V mode. The inverter charger is connected to the AC grid and the only load is the Protection Relay (SEPAM) from Schneider Electric installed on the Medium Voltage Switchgears Board. The charging mode is 99% in "Storage" mode cause the load is very little. The problem we are facing is that after two or three days of operating the Inverter goes to fault mode and the alarms we got is overload and today together with a Low Battery Alarm and the PV station goes out of the Grid. The only thing we do when the fault comes is to go and turn off and on the inverter/charger and the problem is (temporary) solved. Today the fault happened, we got a "grid lost" e-mail message, when we reached the inverter the fault was gone (only the green light when on), as it seems the inverter was inverting. We turned off and on the inverter and the inverter "saw" again the AC grid.

Since we bought the inverter we did not do any optimizations or changed any settings for example for the current output (everything is as it came from the distributor). The system also has a Color Control GX and we can monitor the system from the VRM Portal. Please see attached pictures, videos. Any ideas for the fault or settings needed are much appreciated! No clue why thr fault takes place, on the other hand the overload maybe comes because the SEPAM maybe draws a lot of current in order to power the motorized central medium voltage circuit breaker.20200316 Status Monitoring2.jpgfaults.jpginput current limit.jpgMV SEPAM.jpgBattery.jpgGrid connection restore.mp4

The same behaviour occurs if I use VictronConnect to connect to the Multiplus via a USB/Mk3 interface. I have also attempted to set a lower value using modbus and encounter the same behaviour.

How can I set this value to 0?

ESS Dynamic cut off paramters for OPzV Hoppeccke


I need help about the parameters for cut off. The standard values makes that when the Multi draw up to 2500 - 3000w, they stop invert by low battery.

I have 24 cells Hoppecke 6 OPzS 600 that have a capacity:

C10 - 686Ah (1.80v)

C5 - 590Ah (1.77v)

C3 - 510Ah (1.75v)

C1 - 353Ah (1.67V)

I don't know if the voltages values from Hoppecke for each C value is the nominal o the limit when the battery is empty.

Many thanks!
