Solis S5 6kW three-phase dual MPPT inverter
The 6kW step in the Solis S5 GR3P three-phase line, with dual MPPT and DC isolation. It fills the space between the 5kW and 8kW S5 units, so a three-phase site gets an inverter matched to its roof rather than the nearest size either side.
Description
Sizing three-phase jobs is where a graduated line pays off, and the S5 GR3P runs from 5kW up through 15kW in usable steps; this 6kW keeps a mid-sized roof from being forced onto a larger frame. Farms, workshops and light industrial units with steady daytime loads are the typical buyers. Commissioning carries over from the rest of the S5 three-phase family, and the flat ex-VAT trade pricing means specifying the right size never costs a discount you were holding out for.

What it pairs with
