I'm considering my options for adding an additional ground based array to my current off grid solar setup.
This extra power would be to help run AC side loads in the summer time (EV charging, domestic appliances etc) that have a higher demand than our current 2.4kW array can produce.
I currently use exclusively outback power systems products, with their 60a MPPT charge controller chargin my 9.6kWh LiFePo4 pack.
My question: would I be insane to consider adding this solar to the AC side of things, using a regular grid tie inverter (SMA Sunny Boy or similar)? This would make the wiring a lot easier as I can couple that into the property on the AC side easier than routing it back to the power building.
Or should I just buy another outback MPPT charger and add it on the DC side?
Thoughts....
