What Is It?

Solar-first AC. No battery. No compromise.

The WSE Hybrid Solar AC-DC Air Conditioner connects a solar panel directly to a DC-compatible air conditioner. During daylight hours, the AC runs primarily on solar power — reducing grid electricity draw significantly. When solar is insufficient, it seamlessly switches to grid power. No battery, no inverter, no complex installation.

Works on any sun-facing rooftop — HDB ledge, terrace, condo
No need to change existing copper and drain pipes
1 CU to 1 FCU — single-split compatible
Seamless switch between solar and grid power
Reduces electricity consumption during peak sunlight hours

How It Works

DC solar power. Direct to your AC.

How the Hybrid Solar AC-DC system works — solar panel to DC air conditioner with grid backup

1

Solar panel collects sunlight

A compact solar panel mounted on your roof or ledge converts sunlight directly into DC electricity.

2

DC power goes straight to the AC

No inverter or battery needed. DC power feeds directly into the hybrid AC unit.

3

Grid supplements as needed

When solar output is low, the system automatically draws from the grid — no interruption to cooling.

No battery. No inverter. Direct solar power to your AC — the simplest solar cooling solution available.
