DavidPereira Posted September 25, 2023 Report Share Posted September 25, 2023 Hello, I’m using Luna 2000 5kW batteries and Huawey inverters but according to Huawey connection possibilities, we can have 3 Huawey inverters, charging the battery (your system only permit connection to 1 inverter), if one is M1 (hybrid inverter) and 2 M3 ou M2 on grid inverters. The problem is that with the available PVsol configuration, if we connect the batteries with the M1 inverter of 10kW, we have a wrong simulation as you can see bellow: It’s not possible to have just 27kWh of used energy with this configuration Could you please verify what’s wrong with your software or how can we fix it?

developer_mh Posted September 28, 2023 Report Share Posted September 28, 2023 Hi David Pereira, the charging of DC coupled battery systems by more than one inverter is not possible in PV*SOL right now. You could change the coupling type to AC, so that energetically you get closer to the real thing. Can you point me to a description of the connection possibilities of the M2 or M3 inverters to the Luna 2000? Thanks a lot and kind regards, Martin Quote Link to comment Share on other sites More sharing options...
developer_mh Posted September 28, 2023 Report Share Posted September 28, 2023 I just found a nice diagram that illustrates one possible connection: from https://support.huawei.com/enterprise/de/doc/EDOC1100173562/c29b9ead So yes, this is only possible if you change the coupling type to AC.

DavidPereira Posted September 28, 2023 Author Report Share Posted September 28, 2023 Hello, Thank you for your reply. I know that is possible to connect other inverters such as M2 or M3, but I can't change the coupling from DC to AC in PVsol as you can see in the sreenshot bellow.

developer_mh Posted September 29, 2023 Report Share Posted September 29, 2023 Hi David, yes, you'll need to create a copy of this battery system first. Then you can change the coupling type. Kind regards, Martin Quote Link to comment Share on other sites More sharing options...
