I need some assistance on information from two different sources, but about the same product.
They have both quoted to use Fronius 10.0-3-M
Quote 1: Total of 36 panels on three faces (east, north, west; east & west have 8 panels each)
Said we don’t need any optimisers or micro-inverters as we will generate power pretty much from sunrise to sunset
Quote 2: Total of 36 panels:- 6 on east; 14 on north; and 16 on west
This company stated we NEED optimisers to get 3 strings into 2, so we can connect it to the Fronius inverter, or lose the east panels and stick with 2 strings
Both quotes are similar in price, but Quote 2 says we need 6x optimisers at ~$120 each
System size is 13.3kW with the 10kW inverter, as mentioned above.
If anyone can shed some independent knowledge on this, please help.
