Thunder 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.

The single-panel entry into UKSOL's Hybrid-mount range: one 515W bifacial panel against the same 800W dual-input microinverter as the rest of the range, on an adjustable 15°–43° mount rather than the ground-only mount of UKSOL's earlier Pro Compact 460W. With a single panel, its capacity is well under the 800W output cap.
