How do I power everything while on the road in my RV?
I have several ways to get the power I need to live in my RV. Shore Power, Solar, Generator, Batteries, Alternator are the primary ways to get and/or store power for everyday life on the road.
Shore Power - When I am staying at a campground, I can plug into their electric power pedestal for power and charge my onboard batteries and all my gadgets. Typically the electric is included in the price of your stay but some longer term stays charge you separately via an electric meter. I haven’t stayed at any of these places but it can get expensive if you run your AC a lot. Also I only tend to stay at campgrounds 1-2 days/month to take a break from the road and driving.
Solar - I have 475 watts of solar panels on the roof of my rig, 5 panels at 95 watts each. The panels charge my on-board batteries. There are several components to the solar system, an inverter, charge controllers, etc. but I am not an expert on them. I know how to use them and troubleshoot them but that’s about it. Obviously the solar panels only charge the batteries when the sun is shining so you need to manage your power consumption if you are caught in an area that has multiple days of cloud cover or you are parked in the forest under a lot of trees.
Generator - I have an onboard generator mainly as a back up to solar. The generator runs on propane. But I do need to run my generator to power my air conditioner if I am not hooked up to shore power. I rarely use my AC in the RV. I am chasing 70 degrees around the country so I don’t need it often. On those rare occasions that I do need to cool things off, I will only run the AC for 15-20 minutes to cool things down and then rely on several fans to keep me cool. Once I got to the desert a little too early in the season and the temperature shot up to 109 degrees so I opted to pay for a campground for a week until the weather broke. (If it’s 80 outside my rig can get up to 90+ inside, remember I live in a big tin can!)
Batteries - I have 200 amp hours of Lithium batteries in the RV. The batteries can run everything I have except for the AC. I have multiple USB ports in the rig and also several 110 outlets. I need to turn on my inverter to get 110 power but not for the USB ports. The inverter converts the DC power from the battery to AC power. My lights and USB ports run on DC so no need to turn on the inverter for them. My microwave and my TV need AC power. I have only used the TV probably 4-5 times in 2.5 years. My computer or iPad meets all my viewing needs!
Alternator - I have a second alternator in my engine compartment. When I am driving the alternator will charge my RV battery. I typically don’t drive too long each day so this doesn’t fully charge my batteries if they are low. But it does help to top them up as needed.
Other things - My refrigerator runs on battery power, AC or propane, when it is working.
I’ve had several issues with the refrigerator over the last year or so. Nothing seems to get it to cool. So currently I’m using a portable refrigerator for my cold foods and beverages. Since it draws quite a bit of power, I am supplementing my on board batteries with a portable power bank. I have a Bluetti Solar Generator that I charge with a portable solar panel and that provides power to my portable refrigerator and can charge other devices too. Hopefully I can replace my onboard refrigerator soon, I just need to find a good replacement that fits into the space without too much trouble.
Bottom line is that usually have all the power I require for my daily needs but I still manage my power consumption regularly. The sun is free so I take advantage of that as much as possible…free is good!
