We have a 60kW solar system that is made of the following components:
3x Quattro 48/15000 (one per phase)
2xFronius Eco 27kW
136x440w Pannels
1xCerbo GX
1x SmartShunt 1000 Amps
60kWh Lithium Batteries configured as 48V
We had a 60KVa generator as backup to allow maintenance and when problems occur. However we need to move the generator for another project in another location.
The question we have is what is the minimum size 3 phase generator required that will enable us to start the system and charge the batteries( the time it takes is not really important), we have tested a 7.5kva but when we start the quattros the generator trips. This is a remote location without access the grid.
Thanks a lot.
