What is the difference between an inverter and a non-inverter air conditioner?

An inverter air conditioner adjusts compressor speed to maintain temperature with less electricity, while a non-inverter unit runs at fixed power and switches off and on repeatedly. Inverter models cost more upfront but use less electricity over time and are quieter during operation.

Which BTU size air conditioner do I need for my room?

Choose 12000 BTU for rooms up to 20 square metres, 18000 BTU for rooms up to 35 square metres, 24000 BTU for open-plan spaces up to 50 square metres, and 36000 BTU for large commercial areas. Ceiling height, insulation, and sun exposure all affect the correct BTU for your space.

Can I run a Kelon or Deye air conditioner on solar power?

Yes. Deye solar air conditioners connect directly to solar panels via MC4 and run on DC power during the day, which reduces loadshedding impact and cuts Eskom usage in peak cooling hours. Standard Kelon units can run from a hybrid inverter and battery system if the inverter handles the startup and running load of the unit.

Do Kelon air conditioners include a heat function?

Yes. All Kelon split air conditioners in the SP-Energy range include both cooling and heating modes in a single unit. This means one installation provides comfort in summer and winter across offices, bedrooms, and retail spaces.

What BTU sizes does SP-Energy stock in the Deye solar air conditioner range?

SP-Energy stocks the Deye solar aircon in 12000 BTU, 18000 BTU, and 24000 BTU. Each model connects to solar panels via MC4 and switches automatically between solar and grid power. Browse the full Deye Solar Air Conditioner range to compare models and features.
