GeePower® has designed the new power supply system–Off-Grid solar storage system. It refer to power supplies that are not connected to the public grid. These power storage systems are often called as “Independent Power Systems” or “Remote Regional Power Systems”. They are stand-alone power stations that provide the power needed for a variety of applications. Such as in hospital, at remote station, at business office or places that require 24- hours power supply. The Off-Grid power storage system plays a significant role in these field. 

Overview of Off-Grid solar storage system

This specification describes the Performance Index of the Off-Grid Solar Storage System produced by GeePower Energy Technology Co., Ltd. When electricity supply is insufficient , it will release the power of the photovoltaic system or the power stored by the AC220V charger when needed. Providing AC220V pure sine wave power to supply while Off-Grid.The combination mode of power storage cabinet is a set of 24V150AH battery packs, equipped with 24V40A MPPT solar controller, 28.4V25A power charger, and 2KW AC220 pure sine wave AC inverter , which constitute the Off-Grid Solar Storage Power System. It can supply up to 3.6kwh of electricity. The solar panels are configured according to customer requirements, and the maximum voltage of the solar panels must be less than 100V.
