Product overview

The JA Solar bifacial panels generate power from both the front and rear surfaces, picking up reflected light from the ground to add to total yield. They use PERC half-cut cell technology with multi-busbar construction, which helps in low light and suits the variable UK climate. The all-in-one inverter combines MPPT solar charging and pure sine wave AC output in one unit, so it can run motors, pumps and sensitive electronics cleanly. The battery can be expanded by connecting further modules in parallel as demand grows.

Applications

Suited to summer houses, holiday cabins and remote properties, garden offices, garages and agricultural buildings, backup power for essential household loads, and off-grid workshops and outbuildings.

Installation notes

Installation should be carried out by a qualified installer, with correct cable sizing, fusing and earthing. Any grid backup connection must comply with local wiring regulations. Contact us for technical support before and during installation.
