[QUOTE="bladerunnerpv, post: 550725, member: 35385"] Simple solis only question. One solis 6kw string inverter or two smaller ones for an East-west system? Background... Quote for East West system West roof 10 panels 4.35kWp maybe 9panels East roof 10 panels 4.35kWp Roof ridge line points about 10deg towards East of due South. 29deg pitch Shading factor is about 0.9 for East and 0.82 for West from using easypv buildings beta Quote received uses a solis s6-gr1p6k string inverter, (2 x mppts, 120V startup) with requested ac coupled battery. Seems to me like the 6k inverter is underspecced and will waste energy in summertime which could be reducing the payback time slightly, running future aircon or charging an EV I could use 2x string inverters, say s6-gr1p4k, one for each roof I thought to myself. .. Is there anything specific to solis you guys know of which would prevent this approach? Will it result in more efficient system (less wasteful) Thanks for taking a look PS I'm well aware of other brands of inverters, this query is specific to solis. [/QUOTE]
