Hoping you can help. We are looking at installing a 10kW system and am getting conflicting information from different companies. Our roof is on different levels / sizes & we need to put panels in 3 different places/roof areas. I have been told by one company we can have 3 strings off a 3 phase inverter (Growatt 10kW) and by another that its not possible. Are you able to provide any advice on this?
