Solis S5 5kW three-phase dual MPPT inverter
The Solis S5 GR3P 5kW is a three-phase inverter with dual MPPT and DC isolation, built for premises on a three-phase supply. Workshops, farm buildings and small offices are its territory; it spreads output across the phases instead of loading one.
Description
Plenty of small commercial buildings carry a three-phase supply but only modest roof space, and this is the unit that matches them: proper three-phase generation at a rating sized for a modest array. Two trackers accommodate a split roof or two aspects of a barn. For installers whose domestic work runs on Solis single-phase kit, staying with the brand for three-phase jobs keeps supplier count down and the ordering routine identical. Trade pricing is public, ex-VAT and unchanged at volume.
