PatioSun Max+
PatioSun's flagship: the same dual-MPPT HiFlow PRO microinverter as the Max, but with larger 465W panels for 930W of capacity, the most panel capacity in the range. Whether the roughly £30 premium over the Max is worth it comes down to those extra 40W of panels.
Full PatioSun Max+ reviewThunder Bolt 920W
The sensible middle of the register-listed range: enough panel capacity to make real use of the 800W cap, and two independent MPPTs so one shaded panel doesn't drag the other down. Bracket sets included for a garden or flat roof, shed, outbuilding or rear extension roof.
