Inverter AC in Lebanon: Generator Amps, EDL Hours and Solar
An inverter AC is an air conditioner whose compressor speeds up and slows down instead of switching fully on and off, so it starts gently and uses less power once the room is cool. To see whether a model will run on your generator subscription, multiply your amps by 220 to get watts and compare the result with the rated power on the product page. This guide shows you how, using real figures from air conditioners we sell, and explains what changes on EDL supply and on solar.
1. What "inverter" means on an air conditioner
On an air conditioner, "inverter" describes how the compressor is driven, not where the power comes from. An inverter air conditioner varies its compressor speed: it runs fast to cool a hot room, then slows down to hold the set temperature. A fixed-speed unit only knows full power or off, so it keeps stopping and restarting.
In Lebanon, "inverter" on its own usually means the solar power inverter that turns panel and battery power into 220 V for your home. That is a different device. When you compare air conditioners, look for "inverter AC" or an inverter compressor in the specifications. Our air conditioner buying guide covers the other basics, from heating to features.
Most split units we sell are inverter models: Samsung's AR50F range with a Digital Inverter BLDC compressor, Midea's Storm, Solstice and Breezless series and Campomatic's AC10INV/G, AC13INV/G and AC19INV/G, all with Quattro Inverter, and Hyundai's ASCI inverter series.
2. How many amps does an AC need?
An AC draws roughly its rated power in watts divided by 220, in amps, from a 220 V supply. Start by converting your subscription into watts:
| Generator subscription | Approximate power available at 220 V |
|---|---|
| 5 A | About 1,100 W |
| 10 A | About 2,200 W |
| 15 A | About 3,300 W |
| 20 A | About 4,400 W |
This is the total for your whole home, so the refrigerator, lights and anything else switched on share it with the AC. Now compare it with the AC itself. Samsung lists the power consumption of each AR50F model, so here are real figures:
| Model | Capacity | Cooling | Heating |
|---|---|---|---|
| Samsung AR50F12C1LH/LN | 12,000 BTU | 1,440 W (about 6.5 A) | 970 W (about 4.4 A) |
| Samsung AR50F18C1LH/LN | 18,000 BTU (17,000 BTU rated) | 1,470 W (about 6.7 A) | 1,750 W (about 8.0 A) |
| Samsung AR50F24C1LH/LN | 24,000 BTU (22,000 BTU rated) | 1,960 W (about 8.9 A) | 2,350 W (about 10.7 A) |
Power figures are the manufacturer's values as listed on each product page. Amps are watts divided by 220, rounded.
Reading the table: none of these models fits a 5 A subscription on its own in cooling mode. The 12,000 and 18,000 BTU units sit inside 10 A with roughly 700 W to spare for other appliances. The 24,000 BTU unit uses most of a 10 A line when cooling and goes over it when heating, so 15 A is the realistic choice. Notice too that the 12,000 BTU model lists an efficiency ratio (EER) of 2.44 and the 18,000 BTU model 3.39, which is why their cooling figures are so close. Efficiency matters as much as size.
Product pages for our Midea, Campomatic and Hyundai models do not list rated power yet. If you are on a tight subscription, call or WhatsApp us and we will check the manufacturer's figure for the model you like. Hyundai's ASCI models also list an Ampere Control function, so ask our team how it works on the unit you are considering.
3. Running an AC on EDL, a generator or batteries
An inverter AC is the easiest kind to run on a limited supply, because it starts gently and then settles at a lower speed, but you still need headroom for its full rated power. A fixed-speed compressor typically draws a short surge well above its running current each time it starts, which is what trips many subscription breakers. An inverter compressor ramps up gradually instead.
Expect the highest draw at the start: when you switch on in a hot room, an inverter AC runs close to its rated power until the room reaches the set temperature, then slows down. A few habits help:
- Cool the room while EDL supply is on. When the switch-over to the generator comes, the AC is already running at low speed.
- Do not stack big loads. Avoid running a kettle, iron, oven or air fryer while the AC is pulling the room down on 5 or 10 A.
- Use sleep and eco modes where the model has them, and keep a moderate set temperature.
- Keep doors and windows closed and draw the curtains on sunny walls.
- Look for auto restart. The Campomatic and Hyundai models we sell list auto restart, so the unit comes back on with its previous settings after a cut or a switch-over.
4. Can an inverter AC run on solar?
Yes, an inverter AC can run on a home solar system, as long as the solar inverter's rated output and your battery capacity cover the AC's rated power plus everything else running at the same time. Check three things with your solar installer:
- Solar inverter output (kW): this caps what can run at once. A 1,960 W AC on a 3 kW solar inverter leaves about 1,000 W for the rest of the house.
- Battery capacity (kWh): this sets how long the AC can run after sunset. Running 1,440 W for one hour uses about 1.44 kWh, before losses and other loads.
- Daytime use: panels produce the most around midday, which is also when you need cooling most. Running the AC in daylight and easing off at night makes the best use of your system.
Because an inverter AC slows down once the room is cool, its real consumption over an hour is often below the rated figure, but plan around the rated figure to be safe. We do not design solar systems, so ask your installer to confirm the sizing for your home.
5. Pick the right BTU for a limited supply
Choose the capacity your room actually needs, because on a limited supply every extra watt counts. An undersized AC runs flat out without reaching the set temperature, while an oversized one draws more power than the room requires. Room size, sun, floor level and ceiling height all matter, and our guide shows how to choose the right BTU size for each room.

7. Common mistakes to avoid
Most AC problems on a generator come from ignoring the rated power, not from the AC itself.
- Buying on price or BTU alone without checking the rated power against your subscription.
- Forgetting heating mode. On the Samsung 18,000 and 24,000 BTU models, heating draws more power than cooling.
- Running the AC with a kettle or iron on 5 A. Together they easily go over about 1,100 W.
- Oversizing. A bigger unit than the room needs wastes a limited supply.
- Poor installation. Piping, drainage and airflow around the outdoor unit affect performance, and our team can install the air conditioners we sell.
