Sungrow SBS050 5.12 kWh LFP HV battery

This product is a battery module, that is a brick from which the house's energy reservoir is built. You install one if you want to cover the evening, or several if you want to get through the night as well or a longer outage. The cells are LiFePO4, a lithium variant chosen for safety and long life, and the direct-current switch is already integrated in the module, so the battery can be separated from the installation without additional parts.

One module has 5.12 kWh, and the battery is designed for up to 100% usable energy, that is you can use practically the whole capacity; if more is needed, between 1 and 4 modules can be connected, up to 20.48 kWh, which allows sizing in steps, according to the home's actual consumption. The maximum current of 50 A on charging and discharging means the battery can quickly take up the midday surplus and can support large loads in the evening. Together with the compatible inverters, the SBS family also supports operation without the grid, with up to 5 kW at the output. The module weighs 58 kg and measures 515 x 780 x 182 mm, so it needs a solid wall or platform; the IP55 protection allows outdoor installation, and the permitted operating temperature is -20...55 degrees C. The warranty is 10 years.

Prismatic LiFePO4 cells, rated energy 5.12 kWh, rated voltage 102.4 V, operating range 86.4-116.8 V, maximum charge and discharge current 50 A, designed for up to 100% usable energy. Integrated DC switch and protection against overvoltage, overcurrent and temperatures outside the permitted range; communication with the Sungrow hybrid inverter through a CAN interface. Scaling 1-4 modules (5.12-20.48 kWh), with support for off-grid operation up to 5 kW on the compatible inverters. Dimensions 515 x 780 x 182 mm, weight 58 kg, IP55, operating range -20...55 degrees C.

Who it suits

Suitable for a home with a high-voltage Sungrow hybrid inverter, that wants to start from a single module and grow up to 20.48 kWh as the consumption or the need for autonomy increases.

Terms explained

• High-voltage (HV) battery: A battery that works at high voltage, here 102.4 V nominal, and that connects directly to the hybrid inverters designed for this range.
• Off-grid: Operation without the grid: the installation supplies the house by itself, from the panels and from the battery.
• Integrated DC switch: The switch that separates the battery from the rest of the installation, already fitted in the module and used during interventions or in the event of a fault.

Technical specifications

Recommended applications

• Residential storage on high-voltage Sungrow hybrid inverters
• Backup and off-grid operation up to 5 kW
• Outdoor installation thanks to the IP55 protection
• Gradual expansion of the capacity from 5 to 20 kWh

Warranty

10 years

Technical details

Specifications confirmed from the manufacturer's datasheet

The Sungrow SBS050 is a high-voltage battery module with prismatic LiFePO4 cells, with a rated energy of 5.12 kWh and a rated voltage of 102.4 V. The voltage range in operation is 86.4 - 116.8 V, and the maximum charge and discharge current is 50 A. The battery is designed for up to 100% usable energy.

The module includes an integrated DC switch and protection against overvoltage, overcurrent and temperatures outside the permitted range. Communication with the Sungrow hybrid inverter is over the CAN interface.

The system is scalable: between 1 and 4 modules can be connected, giving capacities from 5.12 kWh up to 20.48 kWh, which allows sizing in steps according to the home's consumption. The SBS family is designed to support off-grid operation as well, with an output power of up to 5 kW on the compatible inverters.

The module's dimensions are 515 x 780 x 182 mm, with a weight of 58 kg, and the IP55 protection rating allows outdoor installation. The operating temperature range is -20...55 degrees C.
