PatioSun Duo
The two-panel PatioSun kit: 890W of bifacial panels against the same 800W microinverter and the Lite's single 445W panel. Same pre-installed steel mount and sold direct, at roughly £250 more than the single-panel Lite.

The smaller of the two Thunder Bolt kits: one rigid panel on a bracket set for a garden or flat roof, shed, outbuilding or rear extension roof, run by the same Hoymiles HMS-800-2WB microinverter as the 920W kit. Its second MPPT input sits unused here. Its panel capacity is well under the 800W output cap.
