5 ton AC unit is one of the biggest that can be powered by a generator.
A 5 ton AC unit generates an outstanding 60,000 BTU of cooling power. This is enough to cool down up to 3000 square feet home.
Where it gets tricky is when we try to determine the size of a generator that can run a 5 ton AC unit.
The key thing is to figure out the overall wattage of such a big air conditioner. Here are 3 simple ways you can do that:
- Check the specification sheet for Power (measured in Watts).
- Check the specification sheet for the EER rating. We can calculate wattage by dividing BTUs with EER rating; ie. 60,000 BTU / 10 EER = 6,000W.
- Check the specification sheet for the current (I, measured in Amps) and voltage (V, measured in Volts). We can calculate wattage by multiplying current with voltage; ie. 25 Amps * 240V = 6,000W.
An average 5-ton air conditioner (with 10 EER rating) will run on 6,000 W.
6,000 W Generator For 5 Ton AC Unit
For most 5-ton air conditioners 6,000 W power generators will be more than enough. Of course, we also need to think about the start-up wattage. Because these AC units need a lot of power, the safe choice is to get a generator that can handle at least 7,000 W start-up wattage.
The best – and most popular – 5-ton AC unit generator is the Westinghouse WGen6000. It’s a 6,000W generator that can deliver up to 7,500W of power; perfect for a 5-ton air conditioner.
This will be more than enough to optimally run a powerful air conditioner.
