Product overview

The SolisStorage PrimePower 109kWh Battery with 50kW Inverter is a turnkey three‑phase energy storage system for small to medium commercial and industrial sites. It combines a 109.7kWh high‑voltage LFP battery cabinet with a 50kW Solis S6‑EH3P50K‑H hybrid inverter, providing up to 100kW PV input for peak‑shaving, load‑shifting and backup.

Key features

• 109.7kWh rated energy (98.7kWh usable) in a compact, pre‑engineered cabinet for straightforward deployment on C&I sites.
• 50kW three‑phase hybrid inverter (S6‑EH3P50K‑H) with 100kW PV input, four MPPTs and seamless <10ms on‑grid/off‑grid transfer for critical loads.
• LFP 3.2V / 306Ah cells with up to 10,000 cycle life (cell manufacturer data) and a 1P112S HV configuration for robust, long‑life storage.
• Industrial‑grade air‑conditioned cabinet, IP55 enclosure with IP66 inverter, integrated aerosol fire suppression and Type II surge protection on AC, PV and battery ports.
• Flexible communications (WiFi, LAN, Bluetooth, dual CAN‑BMS, dual CAN‑parallel, RS485) and up to 10 systems in parallel for multi‑MWh projects.

Typical applications

PrimePower 109kWh 50kW is suited to logistics depots, light industrial units, retail warehouses and small data or telecoms hubs needing three‑phase storage. Typical uses include PV self‑consumption with evening load‑shifting, peak‑shaving on demand charges, backup for critical three‑phase loads and grid‑support schemes where allowed.

Installation and UK expert support

This SolisStorage PrimePower system is not a plug‑and‑play unit; it must be installed and commissioned by suitably qualified engineers with experience in three‑phase hybrids and high‑voltage battery systems. Energian can connect you with trusted UK installation partners for full turnkey solutions including PV, distribution boards, protection and integration with existing site infrastructure.

Our UK‑based technical team can help with system selection, sizing, high‑level design checks and operational queries for your C&I projects. Contact us by phone, email or live chat, or arrange an in‑person consultation at our UK office to discuss your requirements.
