Compare that to a battery voltage reading with the power back on and the power converter operating. This surge is huge, and will often overload a In a 12V system , that is 100 Amps. It is possible to run your air conditioner for extended periods of time while you free camp - purely from your 12v Battery. This Enerdrive 12v Lithium Battery Setup will allow you to run your air conditioner and other heavy amp drawing 240v appliances without the need for a generator or mains power - making caravanning a lot more comfortable. It also has to be big enough to handle the surge that the AC motor takes when the AC starts up. Mel likes things quite a bit warmer than Stef and I do. An Easy Start can be used to run an Air Conditioner (or other compressor or pump) off a small generator (like the Honda 2000), low quality (or low amperage) shore power, or through an inverter for off grid solutions (like tiny homes, RVs and boats). An RV battery monitor can tell you exactly where you stand, measuring the energy that’s flowing into and out of your battery as well as its state of charge or discharge. The size of your solar array, battery bank, and inverter determine whether or not you can regularly run an RV air conditioner with solar. One is the dash air, which is just like the AC in your car. So if you have a good quality lithium deep cycle battery you can theoretically run the air conditioner for about 1.5 hours before you need to recharge your batteries. Get your minds out of the gutter though, we’re talking solar. The other air conditioning system in your RV is the rooftop air conditioner, which runs off of electricity. Say the air conditioner draws an average of 1200W per hour. If we then run the 12 volts from your battery through an inverter it’s changed to 120 volts, but the actual power (watts) doesn’t increase at all. To size these solar components for regular air conditioning I determined how many amps my 13,500 BTU RV air conditioner drew during operation. So we set the air conditioner for 75 degrees. For instance, if you know that your AC requires 150 amps every hour it runs, and you plan on running your AC for three hours each night after the sun goes down, you'll need to add 450 amp-hours to your battery bank in addition to the battery power it takes to run everything else on your RV (150 ah * 3 hours = 450 ah battery). That is the big factor that most people miss. You have two different air conditioning systems in your RV. Therefore, if you run out in the middle of the night you can switch the tank over on the regulator and get propane in the morning. If you pull from both tanks, when you run out you will not have any reserve propane to keep you heated until you can refill. Many RVs come with generators, and the air conditioner is the item that demands it be a high power generator. Image via Amazon There are many different kinds of RV battery monitors on the market, most of which can be installed aftermarket into your RV battery system. It is powered by your engine and blows warm or cool air through the vents. If you are not plugged into an external power source you can still use the 12-volt DC system if you have a 12-volt deep cycle marine battery on your unit. If you want to run your RV air conditioner on solar and battery, remember that a typical RV air conditioning unit outputs 15,000 BTUs of cooling power. As you can see in the video, we beat that considerably, Air Conditioner Settings: Though in the video you can see that the AC was set to a chilly 58 degrees when we turned it on, we didn’t leave it there. The Generator needs to be big enough to run the AC, and in theory let you do other things like microwave when you run it. These AC units generally require about 3,500 watts of power just to start up, and then about 1,500 watts just to keep running. If you know how to use a voltage meter you can check the house battery voltage with your RV disconnected from the AC electrical source. As long as the battery or batteries are charged you can use everything in the RV except the microwave, roof air conditioner, the refrigerator in the electric mode and the electrical outlets. In fact, ignoring the 5% or so of efficiency loss in the inverter electronics, you’ll have the same 120 watts of power on the 120-volt side.
