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.

The 800W in Screwfix's listing title is the microinverter's AC output; the panels total 920W (2 × 460W), and both figures are correct and describe different parts of the kit. Sold with fixings for wall, floor or balcony mounting, but Screwfix's own spec table states a 1-year manufacturer guarantee, well short of the 10-year panel warranties common elsewhere in this catalogue.
