Big living rooms and master bedrooms in Asaba, GRA Port Harcourt and Yenagoa often have a 2HP AC. Can solar run it? Yes, with a bigger system.

How much power a 2HP AC uses

  • Running hard: about 1.5kW to 2kW
  • Inverter AC once cool: often about 1kW to 1.3kW on average
  • Start-up: a normal AC needs a big surge; an inverter AC starts gently

System guide

PartSize for one 2HP inverter AC + home loads
Inverter8kVA to 10kVA pure sine wave hybrid
PanelsAbout 5kW to 6kW (9 to 10 × 600W)
BatteryAbout 10kWh to 12kWh usable for 8 hours

Cost guide

This is close to our 10kVA range: roughly ₦5.1M to ₦6.5M with 15kWh of lithium. Smaller batteries cost less, but the AC will not last the night. See 5kVA vs 10kVA.

Ways to cut the cost

  1. Use an inverter-type AC. Read inverter AC vs normal AC.
  2. Set it at 24–25°C.
  3. Run it for part of the night, then use a fan.
  4. Insulate the ceiling and use thick curtains.

Frequently asked questions

Can a 5kVA inverter carry a 2HP AC?

It may start an inverter-type 2HP AC with little else on, but it will be near its limit. For daily use with other loads, 8kVA or more is safer.

How much battery do I need for a 2HP AC at night?

About 10kWh to 12kWh of usable lithium battery for around 8 hours, depending on the AC model and room.

Is it better to use two 1HP ACs than one 2HP?

Sometimes. Two smaller inverter ACs in separate rooms can be easier on solar, since you can run only the one you need.
