Off grid PV + Battery


Recommended Posts

Dear Paul,

thank you for the project. The problem here is the limitation of the MC box (multicluster box). It can only connect to a maximum of 12 three-phase clusters of Sunny Islands and to a maximum of 360 kW of PV power.


And PV*SOL doesn't support more than one MC box at a time. So I would suggest to break your 5MW project down into a smaller unit, let's say 250 kW, a 1/20th of your current project. You would calculate with 575 PV modules, smaller PV inverters, a load of 32,5 kW and then you can configure the battery system accordingly. Finally you would have to scale up the results by 20, manually.

Sorry that we can't provide a different solution, but this is as it is right now.

Kind regards,
