I want to charge and use battery only when grid is connected using CT clamp.
No backup loads, just use the inverter connected to same circuit that comes from grid.
With CT clamp I want to charge battery when I have 230V going out to grid (excess solar) and use battery till 20% of discharge, when there is not enough being produced.
The question is:
Do I need to connect ACout2, since ACIn will be already connected to ACout2 when grid is present- it should be biderectional?
Thank you
