About This Product

GW5.1-BAT-D-G21, 5 KWH USABLE is a low-voltage lithium iron phosphate (LFP) battery from the GoodWe Lynx Home D Series. Designed to pair with compatible GoodWe hybrid inverters, this 5.1 kWh usable battery module provides reliable residential energy storage for self-consumption and backup applications.

The unit uses safe and stable LFP chemistry and integrates a built-in Battery Management System (BMS) for cell balancing, protection and communication with the inverter. It is designed for modular expansion, allowing multiple units to be connected in parallel to increase total storage capacity as system requirements grow.

This battery is intended for indoor installation and is engineered specifically for seamless integration within the GoodWe ecosystem, including monitoring through the GoodWe SEMS platform.
