Solis FlexCore-OD energy storage system 48–253 kWh · outdoor · S6-EH3P 30K-H(21A)

Overview

Solis FlexCore-OD (48–253 kWh) is a modern industrial energy storage system (Commercial & Industrial ESS) in a sealed enclosure for outdoor installation. It is designed for enterprises, agricultural complexes, logistics centres, filling stations and commercial sites where allocating an indoor room for the equipment is impossible or unnecessary.

The system is housed in a rugged, vandal-resistant enclosure with a high ingress protection rating against dust and moisture (IP54/IP55) and is fitted with a professional climate system (cooling and heating) that maintains the optimum battery operating temperature all year round. The storage core uses safe, long-life LiFePO₄ cells (Grade A+) rated for over 6,000-8,000 cycles. A modular architecture allows capacity to be tailored flexibly from 48 to 253 kWh to specific power supply and backup requirements.

Solis FlexCore-OD features a multi-level integrated fire-suppression system and a comprehensive 5-level BMS protection scheme, and supports peak shaving, Zero Export and integration with solar power plants and diesel generators. Full control, parameter monitoring and diagnostics are performed in real time through the SolisCloud platform.
