Mixing and matching panels (with Solis AC Inverter)

After a lot of thinking, and asking a reputable Victron supplier too, I’m not going to bet the replacement of a 250/100 on 5S just to add 3 x 350w panels (1050w -20% = 840w) to the existing array.

As it is really primarily to heat geysers, removing 1-2kw off the existing system, to be able to recharge a 560ah bank, that this is a much better more efficient option: Solis and Victron on same system
