Low-voltage single-phase

Solis S6-EH1P hybrid inverter (3–10) kW · single-phase · low voltage

Solis S6-EH1P (3–10 kW) is a new-generation single-phase low-voltage hybrid inverter from the S6 series, designed for residential solar power plants. It works with 48 V batteries (LiFePO₄/lead-acid), supports 2 MPPTs with an input current of up to 16 A per string, delivers instant switchover to backup power (UPS <4 ms) and can be connected in parallel with up to 6 units.

Solis S6-EH1P hybrid inverter (3–10) kW · single-phase · low voltage · 3K

Overview

The Solis S6-EH1P hybrid inverter (3–10 kW) is the optimal choice for residential use and small businesses with standard consumption levels. Spanning 3 to 10 kW with 2 independent MPPT trackers, the range is perfectly suited to private houses, apartments, small offices and cafés, making it easy to arrange PV modules on two opposite roof pitches (East–West, for example).

The core value of this model lies in reliably protecting the site during grid outages. The unit switches to backup power in under 10 milliseconds, keeping sensitive electronics, servers and routers running without interruption. Thanks to its substantial headroom, the inverter handles inrush currents with confidence and easily starts «heavy» household appliances — borehole pumps, refrigerators and air conditioners.

This inverter gets the most out of your solar generation. It allows a PV array to be connected with power headroom to spare and is fully compatible with modern high-density PV modules (input current up to 21 A). The result is active battery charging even in overcast weather or in winter.

Solis S6-EH1P gives complete freedom in choosing storage and expanding the system. The low-voltage range accepts any LiFePO4 or lead-acid batteries (40–60 V) without being locked to a single brand. The inverter integrates flexibly with petrol and diesel generators featuring auto-start, manages loads intelligently to preserve battery charge, and supports parallel connection of up to 6 units for gradual capacity growth.
