Off grid PV + Battery

[Paul]

Hi,

 

I'm trying to design a PV with  ESS to supply a constant load however it says no permissible configuration is possible. 

could you please assist to complete the simulation? Also, attached the simulation file.

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,

Martin
