victron quattro 24/8000 Relay program

Hallo. I have a victron quattro 24/8000 with a victron cerbo gx connecete to the system. is it possible to program one of the relays to pull ON when switching to generator (AC1) and stay on? i can not find an option in VE. Config 3. That would be a good thing in the Marine world.

Victron Quattro-II 48/5000/70-50-50 QUA482504010 certifications for german grid?


as the Multiplus-II does not accept generators if configured for the german grid we need to use Victron Quattros-II 48/5000/70-50-50 QUA482504010. They can be bought in Germany but seem to lack certifications for the german grid.

When will the certifications for the german grid be available?

It would be sad if we have to switch to another manufacturer than Victron because of the lack of generator-support/certifications.

Thanx for any hint! :-)

BMV700 connected to NMEA2000 Network / Raymarine i70 can't scan the network


I have bought the VE-Direct Cable (ASS030520310 ) to connect a BMV700 to the NMEA2000-SeatalkNG network of the boat

I can display the Voltage, Ampères,and SOC on each display (Raymarine Axiom and i70, B&G Triton), this is OK.

But since, the Raymarine i70 can't scan the network anymore to define data sources. So I can't choose the RS150 antenna as speed (SOG) source, and the i70 displays "---" as speed.

If I disconnect the VE-Direct cable, the i70 works fine again.

The i70's firmware is updated. The version of the VE-Direct cable is 1.00. Is there a newer version ?

Best regards.

setting up multiplus for solar priority with external grid-linked solar?

Due to irritating conditions with my grid provider, I can't touch my grid-linked inverters - they can't be moved behind my multiplus-II or the grid provider will terminate my feed-in contract and replace it with a very rubbish one..

So - my question..

I have two inverters (physically separate sets of panels) feeding the grid, I have rs485 metering on the solar feed to grid as well as the overall grid. I am happy and allowd to feed to grid from the inverters, but not the multiplus (else the above feed-in rate change), but want to prioritise battery charging and self-consumption.

What is the best way to do this? I plan to setup a Raspberry Pi with Venus OS and the Node-red image.

Solar chargers don't work under ESS

Good day,

Two solar chargers Smart MPPT 150/70-Tr and Smart MPPT 250/70-Tr don't charge the batteries under ESS mode. On VRM the system shows this:


I have set the system to not sell any PV excess to grid. However if I set the system to sell the excess, controllers do start to charge and export PV excess to grid:


Moreover, if we disconnect the VE.Direct cable from both controllers to Venus GX, they do charge battery bank but system doesn't run under ESS:


Any clue of what could be wrong on configuration? I need to set the system up properly for ESS and I have compared all parameters with other systems I have installed that seems to run properly on ESS.

Thank you in advance for your help.

Cerbo GX > No Analogue input option showing


Hi. I’m a new Victron user. Hoping I’m missing something obvious. Tanks are no longer showing on Cerbo GX. And no Analogue input options. Have installed firmware 2.84. No change. No rollback option to previous versions. Any help appreciated. Ps Dealer is on standby for when boat is next accessible so loathed to try anything radical, given my lack of skills!

Charging lithium whit alternator


Im looking a way to ad one more altenator to charge a 10x 200AH 24V bank.

My goal is to get at least 120A on 24 V from it, but cant find a curent limiter or dc-dc charger so big that it will do the job.

I dont want puting 20 of orions for that 2 altenators ( 2 engines), so im looking for single device it can do that.

Money is not a problem, just to have some simpliest and solid solution.

Any advice will be good.

P.s. there is 2 banks of agm motor battery for preventing a spikes if bms cut of servis.

components needed to charge batteries and then go to hot water heater

Good day all.

I am new to this technology and am getting conflicting answers in the "retail world".

I would like to set up a solar system (2x350 Watts) to charge 4x100aH LiFePo4 Batteries and when those are topped up to switch over to start a hot water heater (Bosch or Rheem) to heat the water. Of course at a set temperature I would want to switch off the heater and not have it switch on again until it dropped several degrees so it is not cycling on and off too often.

What components do I need (and what specs) to make this work efficiently. I am thinking I would like to use the Cerbo GX to monitor all of these (and more) devices.

I would appreciate the solution details and any things I should be concerned about that could go wrong.

Many thanks,

Loss of communication to ET112 Grid meter

I finished a new Victron 5KVA Easysolar installation connected to an ET112 Grid meter. The system will run perfectly for a few hours and then looses communication to the ET112 and causes the Inverter to go into a Passthru mode. I then need to reboot the CCGX that will solve the problem untill it happens again after anything from a few minutes to a couple of hours. It will also always happens after a grid failure (load shedding) when the power is restored. I replaced the ET112 grid meter as well as the victron rs485 to usb cable which didn't solve the problem. I re-routed the the rs485 to usb cable and did the software upgrade again without any success. I've done many similar installations in the past and never experienced this issue. Any suggestions to solve this issue.

Multiplus compact version, smartsolar and ESS

Hi, this is what I would like to achieve, see picture also with schematics.

Daytime (green arrows):

- Run load on solar - power from MPPT through inverter to load

- Charge battery on the leftover solar current (split solar charge current to inverter and battery, is the split configurable in some way?)

Nighttime (orange arrow):

- Run load from battery through inverter

- If battery SOC is too low use grid power (light blue arrow from grid through Multiplus)

Equipment I already have:

- Multiplus Compact - mfd. 2013

- Smartsolar 150/60 MPPT - mfd. 2021

- Solarcells and battery

The question is can I create this configuration with the multiplus compact I have if I purchase the Cerbo GX controller? I also read something about gen2 processor on multis needed and some firmware version limitiations. But I could not get the grips of it. So I try to ask here:

1. what should I check with my multi compact to be sure I get this to work as I plan.

2. And can this be done with the cerbo GX and a multi compact?

Smart Battery Senser, MPTT and VE.Direct

Hi all!

I have Victron SmartSolar 100/30 and Smart Battery Senser installed. I also added VE.Direct connection to the SmartSolar to connect to my own systems.

However, I found that the temperature data from Smart Battery Senser isn't available. Is there a way to get it available to VE.Direct? I think it would be smart addition to the system that the SmartSolar would send that data if it's available.

Thank you!

ESS System not feeding in grid :-(

I got a 5k MultiPlus II running with a set of 10kWh BYD LiFePo4 batteries (with their own BYD BMS) en two DC-connected MPPT's with a total PV-capacity of around 2400Wp and a Cerbo "running things"..
The Cerbo is updated to the latest firmware (automagically through the internet). The MultiPlus II is on firmware 2623470 and runs the ESS-assistant more or less with the default values of the German gridcode with internal NS protection.
The only thing I didn't let the assistant change, is the type of battery (because of the BYD-specific settings for Absorption and Float).
This time of year I have quite a surplus of PV-energy so I started experimenting with ESS (Optimized with BatteryLife).
For some reason the system is NOT feeding the surplus of PV back to the grid :-(
Only if I set the grid setpoint to a negative value, the system starts to feed back the PV to the grid at the height I set the negative grid setpoint to....
Otherwise, the BMS (I think) switches off the MPPT's so they don't deliver any PV anymore :-(
For some reason it does that when the BMS says (at VRM and in Remote Console) that the batteries are at 99% instead of 100%. I have no idea why it does that but this doesn't bother me too much ;-).
I set the minimum SOC (unless grid fails) at 95% otherwise apparently the system thinks it should feed the loads from the grid, even when there's still enough PV to do that and even enough to charge the batteries.
So not the actual surplus of PV energy is fed into the grid, but the value set with the negative grid setpoint...
So when there's a cloud before the sun and the batteries are still above the minimum SOC (unless grid fails) then the system feeds the grid from the batteries if the PV drops below the value set in the negative grid setpoint....
I probably have some setting "wrong" to get this result, but I can't seem to think of what could be wrong....
If someone has suggestions..... they are more then welcome.
