Modular Solar 475W Unit
The larger of Modular Solar's two free-standing units: 475W of AC output against the 340W unit's 340W, in a heavier housing built from British-grown timber rather than recycled plastic. Like the 340W unit, its output sits well under the 800W legal cap.

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.
