Superpack All-In-One Off-Grid Energy Storage System

Power Control Module
The energy storage system consists of a power control and battery expansion modules. It can store and release electric energy based on the requirements of the inverter management system. The input and output ports of the battery are low-voltage direct current ports. The power control module is an all-in one off-grid system with inverter + MPPT+ AC charger.

Battery Capacity
The battery supports capacity and power expansion. One inverter supports a maximum of four battery expansion modules in parallel from 5KWH to 20KWH. If it needs to expand power to 10KW, it can connect two inverter in parallel, please consult with our engineer before purchase the system. 

Off-grid ESS Networking
The Off-grid ESS is mainly used in the scenario where there is no grid and the system operates in pure off-grid mode. The pure off-grid ESS stores the generated PV energy in batteries and supplies power to loads when the PV energy is insufficient or there is no PV energy at night.
