Solis All-in-One Off‑grid Hybrid Energy System – 50kW Inverter with 100kWh LFP Battery

  • 50kW three‑phase hybrid inverter with 100.5kWh LFP battery storage in a single C5 PRO outdoor cabinet for commercial and industrial sites.
  • Fast off‑grid/on‑grid switching (<10ms) to keep critical logistics and commercial loads running.
  • Factory‑integrated system with air‑conditioned C5 PRO battery cabinet, IP55/IP66 protection and multi‑layer fire safety for demanding UK and global applications.

Brief description

This Solis All‑in‑One off‑grid hybrid energy system combines a 50kW three‑phase S6‑EH3P50K‑H inverter with a 100kWh EverCore LFP battery cabinet, delivered as a pre‑assembled C&I energy storage solution. It is designed for PV self‑consumption, peak‑shaving and backup power, with support for up to 100kW of DC‑coupled solar and rapid transfer between grid‑tied and islanded operation.

Key features

  • All‑in‑one hybrid system: integrated 50kW three‑phase hybrid inverter and 100.5kWh rated LFP C5 PRO battery cabinet with built‑in EMS and BMS.
  • Usable battery energy: 99.3kWh usable capacity (LFP 3.2V / 314Ah cells, 5 packs of 20.1kWh).
  • PV‑ready design: up to 100kW DC PV input, 4 MPPT / 8 strings, 1000V max input voltage and wide MPPT range for flexible array layouts.
  • Industrial‑grade thermal management: air‑conditioned cabinet, air‑cooled packs and intelligent fan‑cooled inverter for stable operation from ‑25°C to +55°C.
  • Safety and protection: IP55 cabinet and IP66 inverter, aerosol fire suppression, Type II surge protection on AC, PV and battery, plus comprehensive electrical protection modes.

Where to use

This 50kW / 100kWh Solis All‑in‑One off‑grid hybrid energy system is well suited to commercial and industrial sites that need a compact, outdoor‑rated storage and backup solution. Typical applications include logistics hubs, warehousing, light manufacturing, data and telecom rooms, retail and hospitality sites, and small business parks where continuity of supply and bill management are important.

The system can support PV‑coupled off‑grid microgrids, backup power for critical loads, and peak‑shaving against import tariffs, with parallel capability for larger projects when engineered appropriately. For UK projects, Energian can arrange installation via trusted specialist partners and provide design support to integrate the unit into new or existing PV systems, generators and site LV distribution.
