Lithium Battery HV 25.6 kWh Sungrow SBR256
Modelo: SBR256- Sku: SUNGBAT008
- Vendor: Sungrow
Specifications
Product Description
The HV Lithium Battery 25.6 kWh Sungrow SBR256 is the highest capacity configuration in the SBR family. It integrates eight 3.2 kWh LFP modules managed by an advanced BMS to deliver 25.6 kWh usable with 30 A continuous charge/discharge and 100% depth of discharge. Its stackable architecture without wiring between modules speeds up installation, while the IP55 protection rating and natural convection cooling ensure reliability indoors or outdoors. Designed to work in perfect harmony with Sungrow hybrid inverters, this tower covers high daily consumption, provides extended backup during outages, and enables precise tariff optimization strategies.
Main Features
- Total usable capacity: 25.6 kWh (8×3.2 kWh, LFP chemistry).
- High voltage system: 512 V nominal; wide operating range.
- 30 A continuous charge and discharge with high efficiency.
- 100% DOD adjustable to maximize usable energy.
- Modular plug & play design without cables between modules; compact footprint.
- CAN communication with the Sungrow inverter and cloud monitoring.
Advantages or Benefits
- Superior autonomy: covers more hours of consumption and reduces peak energy purchases.
- Reference safety: thermally stable LFP chemistry and BMS with comprehensive protections.
- Fast installation and minimal maintenance thanks to stacked assembly and passive cooling.
- Prepared for outdoor use (IP55) and operation in a wide range of temperature and altitude.
- Native integration with Sungrow hybrid inverters for intelligent control and automatic backup.
Purpose or Applications
Designed for high-consumption homes, small and medium businesses, commercial sites with demand peaks, installations requiring prolonged backup, or projects needing high energy density in limited space. Ideal for new Sungrow ecosystems or expansions seeking to reach maximum tower capacity.
