hey people
I have an installation with 8kVa Quattro and 8kW Fronius with CCGX. The installation was off grid in Nigeira but now I am getting grid connection. However the grid connection is rural, it was unstable and power can be turned off for days.
In this situation the grid may be off for days, is the ESS still the assistant to use. If the the grid connection is there but no power also potentially no voltage. I am unsure if the ESS will still increase the PV inverter frequency.
Any thoughts?
