![]() ![]() The RV air conditioner manufacturer told us it was the solution to our “surge” issue. This type of power surge is a common problem with all different types of compressors and pumps. More on our inverter here: /charge-boat-batteriesįor reference here are a few common inverters and their claimed peak amps:.Plus, that kind of surge is harsh…there are additional benefits to softening the blow (puns intended!). So, the surge from the A/C is greater than what our inverter can handle. Our Cruisair 16,000 BTU A/C states it has a peak of 70 amps when the compressor kicks on. Our inverter can handle a max of 60 amps (noted as “Peak Output Current” from the manufacturer spec sheet). You’ll need to look at the “locked rotor amps” of the A/C to determine if your inverter (or generator/shore power connection) can handle the surge. Inverters have a “surge” or “peak” load.More on our solar set up here: /living-off-grid-rv-sailboat.But conditions must be perfect, and we need to limit the other electronics we use while the Air Conditioning is on. Our 1400 watts of solar has the potential to replenish most of the A/C’s consumption during peak sun hours. Lithium Battery Discount! Relion is offering 5% off to all GWTW Fans!

You’ll need a big battery bank to run the A/C for any reasonable length of time. If you want to run the A/C while you’re living off the grid and on the hook, there are a few things to consider: How We Run Our Sailboats Air Conditioning off Battery Power How do we run the A/C off our batteries? The short answer is, we installed an Easy Start.Conserving fuel, parts and our limited resources is important while living off the grid, especially in remote places. Not to mention there were no fuel stations where we were anchored. #NOWHERE TO RUN CONTRAPTION MAKER GENERATOR#That fuel consumption adds up fast and requires us to service the generator more often. Why not run the generator? 10 hours of generator uses about 5 gallons of fuel.(It’s a challenge to manage resources with 5 additional people who are not accustomed to living with limited resources). Why not run the A/C overnight? We don’t have enough battery power to run the A/C all night and keep up with all the other power demands of the boat.It was the hottest part of the day and it’s o-so-nice to circulate air and bring down humidity. Why didn’t you run the A/C? We did in the afternoons when the sun was high (and our solar panels were bringing in lots o’ power to the batteries).Here’s a quick recap of what we covered in the video: Kinda cool right?! Ok, now about those details. ![]()
