GSL ENERGY HV-G4–G12 Pro 50 Ah High-Voltage Stackable LiFePO₄ Battery for Home Energy Storage

50 Ah LiFePO₄ modules with 4 to 12 modules per stack for residential solar storage.

The GSL ENERGY HV-G4–G12 Pro Series is a modular high-voltage LiFePO₄ battery system designed for residential solar energy storage and whole-home backup. The series offers nine configurations, from HV-G4 Pro to HV-G12 Pro, with 4 to 12 50 Ah battery modules connected in series per stack. An integrated battery management system (BMS) monitors battery status during charging and discharging. The series supports CAN, RS485, and TCP/IP communication, integration with compatible hybrid inverters, and up to five battery stacks in parallel. Installers can select a configuration based on the home’s energy storage needs and the inverter’s battery voltage range.

Modular High-Voltage Battery Storage for Homes

The GSL ENERGY HV-G4–G12 Pro Series is a stackable high-voltage LiFePO₄ battery designed for residential solar storage and backup power. It offers nine configurations, each built with 4 to 12 50 Ah battery modules connected in series.

Adding modules increases both the stack voltage and nominal storage capacity. Installers can select a model based on how much solar energy the household wants to store, how long it needs to power selected loads during an outage, and the battery voltage range of the compatible hybrid inverter.

The integrated battery management system (BMS) monitors battery operating conditions during charging and discharging.
