Solis S6-EH3P hybrid inverter (30–60) kW · three-phase · high voltage · 30K

Overview

Solis S6-EH3P (30–60 kW) is an ultra-high-power industrial-class three-phase hybrid inverter for building large off-grid and energy-independence systems. Rated from 30 to 60 kW, the series targets large enterprises, production workshops, agricultural complexes, shopping centres, business parks and hotel complexes with a three-phase supply.

The model works with large-capacity high-voltage battery arrays. The high bus voltage minimises current losses and cable heating, guarantees maximum efficiency and delivers ultra-fast battery charging and discharging during short windows of grid availability or generator operation.

The inverter is designed for maximum flexibility: a multi-channel MPPT tracker system and support for 21 A per string allow large PV fields to be connected across different roof pitches or façades using the most powerful modern PV modules. The unit switches to backup power instantly, within 10 ms, and easily copes with the enormous inrush currents of industrial machine tools, pumping stations, ventilation systems and refrigeration plants.

Solis S6-EH3P (30–60)K-H offers the full range of intelligent energy management: diesel generator compatibility, Zero Export, peak shaving and parallel connection of multiple units to create megawatt-class off-grid networks.
