How big of an air conditioner battery do I need?
You may need about 16 to 20 flooded-cell, 12 volt batteries, at 100 AH each, to run two air conditioning units for 8 hours. That could end up weighing as much as 1,000 pounds, and take up a lot space.
Will a power inverter run a window air conditioner?
A large power inverter can run a small window air conditioner. Inverter capacity is measured in watts. Units are available from under 200 watts to more than 5,000 watts capacity. The size inverter you will need depends on the wattage demanded by your air conditioner.
How many 12 volt batteries do I need to run AC?
A typical 12 volt lithium battery, delivering 100 AH, weighs about 30 pounds. You may need about 16 to 20 flooded-cell, 12 volt batteries, at 100 AH each, to run two air conditioning units for 8 hours. That could end up weighing as much as 1,000 pounds, and take up a lot space.
How long will a 100 Ah battery run an RV AC unit?
For example, a 100 Ah lithium battery will power a typical 15,000 BTU RV AC unit for about 30 minutes. If you’re RVing in hot weather, running your AC for 30 minutes likely won’t do much to increase your comfort. However, if you had a bank of eight 100 Ah batteries, it would run for about four hours.
How many 12 volt batteries do RV boondockers use?
Perhaps 50\% of full time RV boondockers have two 12 volt batteries or two 6 volt batteries to power their DC accessories and appliances. Another 25\% have four or more batteries. The other 25\% have just a single 12 volt battery. Appliances that run on AC current (110V or 120V) don’t run on battery power.
What size inverter do I need to run my RV air conditioner?
A 15,000 BTU air conditioning unit is what most RVs come equipped with these days. Each of these units requires a minimum of 3,500 watts just to kick start a unit. It then takes about 1,500 watts to keep that unit running. This means you will need at least a 4,000 watt DC-to-AC power inverter, to convert your battery power to usable AC electricity.
