I have recently upgraded from a 8kva Sunsynk inverter to the new 16kva inverter. My whole home is on the essential load. I am struggling to understand what settings I should be applying for no export/solar export/limit to load only...? My installer has selected "no export" and "limit to load only", but I am not sure why or if this is correct. I have a large solar array (~14,000w) and a large battery bank (~36kwh). Any advice or layman explanations of what each of these settings actually mean? The manual isn't particularly clear.
