Product Details of Stackable Energy Storage System


How Stackable Energy Storage Systems Work

With Only Mains Power but No Solar

When the main power is ON, it charges the lithium storage battery and supplies power to the load at the same time.

If there is a power outage, the energy storage battery will supply power to the mains.

With Only Solar Power but No Mains

During the day time, solar power is given priority to power the load, and any excess energy generated is used to charge the lithium storage battery.

At night, the storage battery will supply power to the mains

Hybrid Solar Power and Mains
