What Is It?

Solar-first AC. No battery. No compromise.

The WSE Hybrid Solar AC-DC system uses DC power generated directly from solar PV panels to run your air conditioner. Unlike conventional solar setups, there's no conversion from DC to AC and back โ€” meaning less energy loss and no expensive battery storage required.

When solar output is strong (typically 9amโ€“5pm), the AC runs almost entirely on solar. When solar is weak or absent, it auto-switches to grid power seamlessly.

  • No storage battery required โ€” lowest cost solar AC system
  • Solar DC powers the outdoor condensing unit (CU) directly
  • Automatic grid backup โ€” no manual switching
  • Compatible with existing single-split AC units
  • No need to change existing copper and drain pipes

System Components
โ˜€๏ธ

Solar PV Panels

Flex or rigid panels mounted on roof. Highly customisable depending on space.

๐Ÿ”Œ

Outdoor Condensing Unit (CU)

Built-in MPPT solar charge controller โ€” uses solar DC power first.

โ„๏ธ

Indoor Fan-Coil Unit (FCU)

Standard indoor unit โ€” same comfort as a regular AC.

How It Works

DC solar power. Direct to your AC.

1

Solar panels generate DC power

Panels on your roof generate DC electricity from sunlight. Flexible or rigid panels โ€” your choice.

2

CU uses solar DC first (USES DC POWER FIRST)

The outdoor unit has a built-in MPPT controller. It prioritises solar DC power. When solar is sufficient, the grid draws near zero.

3

Auto grid backup when needed

When solar is weak or absent, the system draws from the grid โ€” automatically, with no interruption to cooling.

During sunny hours, the air conditioner runs almost entirely on solar energy โ€” up to 90% electricity savings on your AC.

Who is this for?

  • Homeowners with a sun-facing roof top
  • Single-split AC units (1 CU to 1 FCU)
  • Anyone looking to replace or new-install an air conditioner
  • Those wanting solar savings without the battery cost

Additional works required:

  • Cabling from solar PV panels to the CU
  • Existing AC cables and isolators can be reused
