Single phase installation in Munich with bifacial modules on a North and South facing pitched roof. There were a lot of complications along the way, as most of the rafters are inaccessible, snow guards could not be removed and there are a lot of obstactles in terms of ladders, a huge chimney, 4 windows, etc. - In the end, metal tiles with roof hooks by Otto-Lehmann were used, with an insertion system (Novotegra), BRC optimizers on one string, a single-phase hybrid inverter by Fronius with large input currents but low voltage levels, and a small BYD HVS battery set. This was a lot of work in planning with individual adaptations on site. Quite happy with the result.
