400 Watts of Solar for $37 ?
Complete Kit
Forum Discussion
I have the 20a Eco-W and it is a very good controller. Costs about $102 US. It does have limitations. 42 or 45 Voc total input and about 300w
So my 230w, 37Voc panel is a good match. However four 100w panels at 22Voc each and 6.2a Isc each is not. So I wonder about the "real" kit at $6xx.
Four 100w in parallel will be 22Voc but 24.8a so that goes over the amps and the watts. Just two panels in series at 44Voc is over the Voc limit.
Strange sort of "kit" IMO.
