An excellent way to guarantee you always have electricity when needed is to have a generator for your RV. But some people might find it strange to use the generator to charge the batteries in an RV.
We’ll demonstrate How To Charge RV Battery With Generator correctly. We’ll also provide some advice on how to maximize the effectiveness of your generator while the battery is being charged. So, whether you’re a beginner or an expert when it comes to generators and batteries, we’ve got the information that you need.
What You’ll Need
When you’re prepared to use your generator to charge your RV batteries, you’ll need these things.
A different size generator with the power to recharge your RV’s battery is required. The output information is often shown on the label of generators, making it simple to determine if they are strong enough to charge your battery.
Before starting the generator, you must completely charge the battery.
RV Battery Charger
This will make it easier to make sure you are getting the most out of your generator.
Make sure the RV is level and placed where the generator can reach it (a park or driveway).
It would help if you had the appropriate cables to connect your generator to the battery. The electricity that the generator will provide should be able to go via the extension cable.
AC Power Adapter For The Generator (If Needed)
Some generators have insufficient built-in AC converters to recharge your RV’s battery. In this case, the generator will need an adapter to get electricity from an AC outlet.
Array Of Outlets
On the generator, you must have at least one electrical outlet. You may do this to connect the RV battery charger to it.
Use a screwdriver to access the battery box on your RV.
You’ll need a wrench to tighten the charger wires on the RV battery. They are less prone to separate when the battery charges due to this.
Not all generators will come with an AC outlet built-in. If this is the case, you’ll need to use a screwdriver or a knife to open up the generator and find out where the outlet is. Some generators have an AC outlet on the side, while others may have one in the front or back. Once you find it, use sandpaper to smooth down the edges and prevent any sharp metal from puncturing your extension cord.
While working on specific generators, the illumination may not be too intense. Make sure you have a flashlight with you so you can work while seeing all the components correctly.
You must have access to water while working. You’ll be able to do this while working and clean up any spills or accidents.
Make sure you have several more on hand if your generator doesn’t have built-in batteries. As a result, you won’t always need to use your generator to run your RV battery charger.
You’ll need a lighter for starting the generator, so have some lighter fluid on hand.
You must have fuel on hand if you want to use the generator. Before turning on the generator, ensure there is at least a quarter of a tank.
Starting fluid can be required to start the generator. Although it’s uncommon, keep some on hand just in case.
There will be gas emissions while the generator is operating. As you operate, ensure you have a hose to ventilate the space.
Use a screwdriver to access the battery box on your RV.
