Deye SE-G5.1 Pro-B LV Battery 5.1 kW

Deye SE-G5.1 Pro-B – 5.12 kWh LV LiFePO4 battery module

Product description

Deye SE-G5.1 Pro-B is a low-voltage energy storage module based on LiFePO4 technology, designed for ESS systems in residential and commercial applications. A single battery offers 5.12 kWh of energy, a capacity of 100 Ah and a nominal voltage of 51.2 V, operating within a range of 43.2–57.6 V. The recommended charging and discharging current is 50 A, the maximum is 100 A, while for 2 minutes at 25°C the device can operate with a peak current of 150 A. The module supports CAN2.0 and RS485 communication and can be installed on a wall, on the floor or in a standard 19" rack cabinet. The design allows up to 64 units to be connected in parallel, enabling the construction of a system with a capacity of up to 327 kWh, while the recommended depth of discharge is 90%.

Technical parameters

Model comparison

The datasheet presents SE-G5.1 Pro-B as the common battery module for several installation variants of the Deye Spring SE Series system. The module itself retains the parameters 5.12 kWh / 51.2 V / 100 Ah, while the manufacturer shows different ways of integrating it, including SE-G5.1-Pro-B-Ultra, SE-G5.1-Pro-B-Cabinet and SE-G5.1-Pro-B-BC. The differences mainly concern the enclosure, mounting method and battery installation options, while SE-G5.1 Pro-B remains the basic energy storage module. Thanks to the possibility of connecting multiple units in parallel, the system capacity can be increased without changing the basic battery type.
