50kVA 50/80/100/120/130kWh Commercial Battery Energy Storage System

Commercial Energy Storage Sized for the Site

A small commercial storage project needs more than a target battery capacity. The system must also match the site’s peak demand, solar generation, backup priorities and available installation space. The GSL ENERGY 50kVA series offers four nominal energy configurations—81.92, 102.4, 122.88 and 133.12kWh—so project teams can select a capacity that reflects the operating profile of a shop, farm, warehouse, office building or light industrial facility.

Solar Integration and Energy Management

Paired with a three-phase hybrid inverter, the LiFePO₄ battery system can store solar generation for use later in the day or charge when electricity is less expensive. During periods of higher demand, stored energy can help reduce grid purchases and manage peak loads. Where backup operation is required, the project design should identify critical circuits and confirm the required transfer arrangement, output power and expected runtime.

The published inverter configuration provides four MPPT inputs, a maximum PV input of 65kW and an MPPT voltage range of 150–850V. These figures give EPC contractors a basis for assessing solar array compatibility; final PV string design and operating modes should be confirmed against the selected inverter and site conditions.

Built for Project Deployment

The floor-mounted battery enclosure uses LiFePO₄ chemistry and carries an IP55 rating. Battery monitoring and protection are managed through the BMS, with communication options listed for system integration. The series is specified with a 10-year warranty and a cycle-life rating of at least 6,500 cycles under the stated test conditions.

GSL ENERGY supports capacity selection and system configuration for distributors, EPC contractors and commercial project developers. Share the site’s load profile, solar capacity, operating schedule and backup requirements to determine the appropriate battery model and inverter configuration.
