We will be primarily relying on our solar panels to keep our battery bank charged. However, it is not only nice to have the required infrastructure in place should we ever need or want to connect to the grid; often, if you’re home is solar powered, you are still required to be connected. It is better to have, and not need; than to need and not have.
So lets take a look at the options and differences. If you just want to read about connecting your home solar array to the grid, go ahead and skip down to the next section.
“Shore Power” – RV / Skoolie connection to the Grid
Typical Campground “Hook Up” Service
Most importantly everyone should know how to test a receptacle BEFORE plugging in the first time! It’s always good practice to use a polarity tester and test the campgrounds wiring before connecting your expensive electrical system. It’s also not a bad idea to use a multimeter and check that the voltage is correct.
Before connecting ensure that you have everything turned off.
15/20 Amp – Basically the same as running an extension cord out to your RV. Should we ever require shore power, we would like to power our outlets AND charge our 12v battery bank; which is why we are installing a 30 amp hook-up.
30 Amp – TT-30 (or RV 30) is the national recreational vehicle standard. The 110v 30 amp service is capable of supplying up to 3,600 watts. The TT-30 follows standard color codes for wiring 110v. Hot is connected to the gold screw, or the 5 o’clock location when looking from the back. Neutral is connected to the silver screw, opposite the hot connection. Ground is connected to the green terminal at the top.
50 Amp – For safety and simplicity we wont be using the 50 amp service due to the added complexity.
