S6 Mini 1kW 1MPPT 1PH Inverter - with DC isolator

Solis S6 Mini 1kW Single Phase Grid-Tie Inverter with DC Isolator

The Solis S6 Mini Series 1kW grid-tie inverter (part number SOL-1.0-MINI-S6-DC, manufacturer model S6-GR1P1K-M) is a compact, single-phase string inverter with an integrated DC switch, built for small-scale single-tracker PV installations. Rated at 1000 W output with a maximum PV input of 1.5 kW, this single MPPT inverter achieves a maximum efficiency of 96.6% and a Euro efficiency of 95.3%. It is compatible with high-efficiency and bifacial modules, accepting up to 14 A input current and a maximum PV voltage of 600 V. The fanless design produces less than 20 dB(A) and carries an IP66 ingress protection rating. Available from DECO Group, a UK solar wholesaler for professional installers and trade buyers.
