GoodWe BAT25-56 HV
The GoodWe BAT Series is a modular, high-voltage lithium iron phosphate (LFP) battery storage solution designed for off-grid solar and microgrid projects across West Africa, the Sahel, and ECOWAS regions. With capacities from 25.6 to 56.3 kWh per unit and stackable configuration supporting up to 337.8 kWh total capacity, it delivers the energy independence and scalability needed for rural electrification initiatives in remote, off-grid locations where grid connectivity is unavailable. Built on proven LFP cell technology with over 6,000 cycle life, the system combines robust performance, superior safety, and reliable long-term operation in extreme heat and harsh environmental conditions typical of West African deployment. Its flexible, modular design enables rapid installation and capacity expansion for diverse small commercial and industrial applications requiring dependable energy access across the region.
