Hi Guys,
Just wondering about how a SI/SB microgrid works. If all the PV is
connected to SB inverters, what happens if the loads manage to drain the
batteries to their low voltage shutdown? Wouldn't the SB stop providing
the AC sync so then the SB wouldn't have anything to sync to even if
they had power available from the PV?
How is this handled? It seems to me you would always want to have some
amount of PV DC coupled.
Thanks,
