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

Meter it with the Solis 3phase Meter DTSD1352 with 3x150A:5A CTs or the Solis Meter 3PH Eastron V2 (with CT), and manage export through the Solis Export Power Manager EPM3-5G-PRO. The S5-series logging stick is the Solis S5 Wi-Fi Data Logger 4Pin; confirm revision-dependent fits against Solis's current pairing list.

Three-phase only, rated 6.0 kW with dual MPPT; it is not suitable for a single-phase supply. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
