The device includes AC/DC function a pure sine wave inverter, an inverter charger,a UPS and an AVR.
It can be wall mounted or kept free standing.

With UPS feature, it acts as a backup source of power for electrical appliances: for powering fans, pumps, central heating, computers, internet devices, home appliance etc.

If you prefer you can connect solar panels, even in additional to an external solar regulator.

With a wide range of applications, you can use it for supply your home devices in case of a power cut or off-grid.

But it can only work with pure sine wave inverter generators.
