    When using a Fronius PV-inverter in a Victron system, you will remove the Fronius meter, and reconfigure the Fronius to have no limit. You will then enable modbus-tcp for it, and then configure the GX-device to control the Fronius. The Victron system then acts as the limiter. The ET340 is then used by the Victron system.

    Just a note on the ET340. I far prefer the older EM24. The ET340 is really slow on its measurements (2 second refresh rate). If you have old style disk meters you may not care, just something to keep in mind.

    Noted, thanks very much.

    Need a bit more detail. Do you,

    1. Want to run a Victron inverter, with a GX device an an ET340... but then have the Fronius use its own energy meter?

    2. Want to run a Fronius inverter, but use an ET340 with it?

    3. Use the ET340 in a Fronius system that already has its own energy meter, for some sort of independent metering.

    The answers would be:

    1. Using a Fronius inverter in a Victron system with its own energy meter is not supported.

    2. You can't use an ET340 to control the limiter in a Fronius (aas far as I know anyway).

    3. Of course you can do that, the two systems would just be independent of each other.

    I also have to note, at this point, that the ET340 is not a Victron product, although they do stock and resell it. It's a Carlo Gavazzi product.

    I want to install 3 phase  15kVA victron inverter system with a GX device and a 15kW fronius inverter,

    Thanks for the information,its a recent model (those with high PV input voltage). I will try your recommended values and advise you on the results!

    thanks @Coulombyour magic worked out.

  4. Hi,

    i have an installed a mecer axpert 5kVA inverter, 4xUS2000 pylontech,10x 340W solar panels.

    the only settings availability in terms of priority are U, SBU and S only. I have selected SBU as per the client's request but Utility is charging the batteries whenever the sundisappears,it is not using batteries.What could be the problem

    setting 12 - 47.5V

    setting 13- 52.2V

    setting 26- 53.2V

    setting 27 - 51V

    setting 29 - 46.5V

  5. dear friends, may you please assist me on this one.

    i have 3x 8kVA Quattro inverters, all to be connected in a 3 phase set up.I have my AC in  from a 3 separate double pole 63A into individual 3 quattros.,CCGX powered up,pylontech US2000 connected.

    VE Bus cables connected from the first quattro-2nd quattro ,3rd quattro the into the CCGX, I have set same values (charge current,float,absorption etc for each quattro).

    the errors i am getting on the CCGX  #3, #10,#17 can someone give me light to solve this? This is my first 3phase victron installation.

    There are a lot of info available on the Victron site, but for us to help you accurately, we would need more info. 

    You can find more info  here: https://www.victronenergy.com/support-and-downloads/systems#item=system-quattro and this document: https://www.victronenergy.com/live/ve.bus:manual_parallel_and_three_phase_systems  helped me a lot when I did my first 3 phase system. 

    Some Victron Schematics:




    Thanks for the information very helpful.

    One more question, Are you using the cable pack US2000/US3000 supplied with Pylontech? If not ,how do you connect the Pylontech with a much thicker cable say 70mm2.This is for a victron -pylontech installation.

    Jip it would be a challenge, at 200watt the barriers will read for example 54 volt (100%), then you start a 1800wh kettle and it will drop to 52 volt, your calculation will now say that the batteries are at 80% or the likes. Now the kettle switches off and the volts go back to 54 volts or 100%. so in a space of 5 minutes the SOC went from 100 to 80 and back to 100%. and this will happen for every load that switches on and off... 

    As you can see, this will never ever be an accurate way of doing it. 

    The best option is to install a battery monitor, it will measure the coulombs in and out of the battery and give you a much more accurate reading of what the SOC/DOD really is. 

    Noted,Thanks very much!

    Regretfully there is no formula for batteries in use. Voltage change depending on load, so you can not use voltage as an indication of SOC/DOD. The only time you can is if you disconnect the batteries and let them rest for a while. Those values you will need to get fro your battery manufacturer. It varies from brand to brand.. 

    The challenge is that the inverter settings are interms of voltage and I would like to set them at 50% DOD

    Hi, I’m new to the forum and hope someone could please assist. Have purchased a new RCT VM3 5kva with 2x Dyness B4850 batteries to replace my previous Axpert 5kva/ Lead Acid setup. Have connected up the above 100% by the book but now getting fault code 61 (communication failure) between the inverter and batteries. I’m using a custom Comms cable (made up for Axpert King by the Dyness supplier) via RS485 Port.  I have two of these cables and have tried the second comms cable also but the problem continues.

    The battery PIP settings are as per Dyness manual for Voltronic inverter (pin 3 on on master, all pins off on slave)  but have also experimented around this without success. The inverter setting 05 has also been set to ‘Pyl’on. 

    Would appreciate any advice! 




    I am having a same problem but this time with 3*US2000 pylontech and a Kodak MK .I put setting 5 to PYL but there error 61 started flashing,still on this setting I couldn't change values.After less than an hour the inverter disconnected all chargers and no output.I then put the setting 5 on USE and manage to adjust the values and now seems working.

    Looking forward to seeing what will happen in the next hour.
