GoodWe BAT Series 14.3kWh

The GoodWe BAT Series 14.3kWh battery is a high-capacity, low-voltage energy storage solution for residential solar energy systems. It enables homeowners to store excess solar power generated during the day and use it during peak hours or power outages. Designed to integrate seamlessly with GoodWe’s single-phase and three-phase low-voltage inverters, this battery provides dependable energy storage to manage your home’s power needs.

Built with 280Ah long-life cells rated for 6,500 cycles, the BAT Series delivers exceptional durability, offering up to 18 years of daily cycling. Its high charge/discharge rates ensure quick energy capture and fast response to household demand spikes, while optional low-temperature heating makes it reliable even in harsh climates.
