Description

Product Description

The Sungrow 25.6 kWh battery package forms part of Sungrow’s SBR high-voltage battery range, engineered for long service life, maximum usable energy, and seamless integration with Sungrow single-phase and three-phase hybrid inverters. The system is constructed from stackable battery modules combined with an intelligent Battery Management System (BMS) that continuously monitors and protects each cell. Using lithium iron phosphate chemistry, the battery provides excellent thermal stability, high cycle life, and consistent performance under demanding operating conditions. Its modular floor-standing design allows future expansion, making it ideal for growing energy needs, load shifting, self-consumption optimisation, and reliable backup during grid outages.
