A complete off-grid solar power kit built around 5 x JA Solar 450W bifacial panels and a 2.5kWh 24V lithium battery, sized for locations without reliable mains power. It suits summer houses, cabins, remote workshops, garages and agricultural buildings, and can run as a true off-grid system or accept grid power as a backup charging source. A wiring diagram and UK technical support are included.

Off grid solar power kit features

• Solar array, 5 x JA Solar 450W bifacial panels with black frame, 2.25kW total PV
• Battery storage, 2.5kWh 24V lithium ion battery, expandable with further modules
• Inverter, all-in-one unit with built-in MPPT solar charger and 230V pure sine wave output
• Cabling, 15 metres of solar DC cable pair ready for connection
• Protection, DC fuses and isolators for solar and battery, plus AC isolators and consumer unit
• Mounting, complete mounting kit for all 5 solar panels

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.
