General Information

General Information: The specification is adapted for a 48 V 100 A·h battery and includes technical characteristics, dimensions, operating requirements, and usage warnings.

Electrical Characteristics and Test Conditions

Test Conditions: ambient temperature 25±5℃; relative humidity 45%–75%. Normal charge: CC (0.5C) / CV (54 V) mode until overcharge protection is triggered, or until fully charged when the charging current decreases to 0.05C, after which charging stops for 1 hour.

Battery Protection and Management

Circuit Protection: The batteries are equipped with a LiFePo4 Battery Management System (BMS) that monitors each prismatic cell during charging and discharging, protects against overcharge, over-discharge, and short circuits, ensuring safe and optimal battery operation.

This hybrid system from Rosen is ideal for those seeking energy independence, combining high efficiency solar modules, a durable LiFePo4 battery, and reliable control electronics.
