Electric system

We commonly associate electricity with civilization. Even with modern civilization. After all, the ancient Romans had civilization but no electricity.

But electricity is not unnatural. And with a magnet, some wire, and some tape, we can create it in total wilderness where we do not even have housing.

Compared to, for example, the basics of a combustion engine, the basics of electricity are much easier to apply to comfort in a totally remote location without supplies.

Electricity is essential. For freedom housing and for independent motorhomes. And the basics of applied electricity are not difficult to understand, and if a system is kept simple, one does not have to be an electrician to maintain and repair such a system.

But look at the wiring of a typical commercial motorhome. That can be maintained only by an electrician. Not just any electrician but only the one who has set it up.

To start with, there is always a set of batteries. They will usually be charged from the car engine and then apply electricity to some 12-volt appliances and an inverter that powers 220-volt appliances. And there typically is a electric inlet which to connect to mains power when available. If hooked up to mains power, the batteries are automatically charged.

That sounds good but isn't because you are not power-independent.

You are not power-independent because you cannot go to a remote place and stay there for a few days and have electricity. You have the following options which are all no good:

1. Drive every day. You will probably have to drive a few hundred kilometers to have enough recharge for electric lights and fans, maybe a video player and a 12-volt refrigerator.

2, Keep the car engine running in neutral all day when parked. You won't do that very long. Calculate a full tank for 2 days. That really is very uneconomical electricity.

3. A hook-up generator. But that is noisy, and you have to bring fuel along.

4. Solar panels. Yes, they make more sense. But solar panels are a comparatively new solution, and they usually do not fit in well with the engine-charged mains hook-up systems.

And now for the weakest part. That are the batteries. Batteries are expensive and do not last. After just 100 days or so, they will already have only half capacity. Lead-acid deep cycle batteries last longer but have to be placed outside the car for the hydrogen they release. They have also not been built to withstand the shocks of potholes.

And even a single deep-cycle battery will not supply enough energy to be energy-independent. You will need multiple batteries in a battery bank, and this bank has to be set up in a manner that prevents rapid battery deterioration, hydrogen emission in the interior, and is easy to maintain and repair by the owner, certainly without having to drive back to the manufacturer.
