How It Works

Solar in, cool out — all day and night.

How the Off-Grid Solar AC works — solar panels to MPPT controller to battery storage to air conditioner

Solar panels collect energy

Roof-mounted solar panels generate DC electricity from sunlight throughout the day.

MPPT controller optimises and stores

The MPPT Solar Charge Controller maximises panel output and charges the storage battery bank.

AC runs on solar — day and night

The AC draws from solar during the day and from batteries after sundown. No grid connection needed.

Zero electricity bills. The system is entirely self-sufficient — no grid, no monthly utility cost.

Who Is This For?
