Product Overview

Working Modes

It has following working modes:

1.Utility provides power to the loads as first priority. Solar and energy storage battery provide power to the load only if utility power is not available.

2.Solar energy provides power to the loads as first priority. Energy storage battery  provides power to the loads at the same time if solar energy is not sufficient. Utility provides power to the loads only when battery low voltage happens.

3.Solar energy provides power to the loads as first priority. Utility provides power to the loads at the same time if solar energy is not sufficient. Energy storage battery provides power to the loads only if solar energy and utility power are not available, or solar energy is not sufficient and utility power is not available.


Versatile Charging Options

Solar Priority

Charge the batteries with solar panel as priority. Charge batteries using utility power only when solar energy is not available.

Combined Charging

Solar energy and utility power charge the batteries at the same time.

Solar Exclusive

Solar energy will be the only charging source no matter utility power is available or not.
