When i started working on Pamthevan I had no idea on how electricity worked. Even after finishing the electrical system i still have no clue. But i guess it’s a bit like using a car while not knowing how it exactly works: you know it’s dangerous and you know you have to be careful!
Electricity is dangerous, so unless you feel 100% confident you can do it, i would rely on an expert electrician.
That said, with a little practice, loads of reading and some precaution i feel like anybody can install a fairly simply electrical system in their van.
Pamthevan’s system is VERY simple as it only powers the LED lights and an inverter to convert 12v AC to 240v DC.
The two most important pieces of equipment you will need are:
- a leisure battery, from which you will draw energy to power your devices;
- some kind of split charge relay to allow you to recharge your leisure battery from the starter battery.
So the first thing you will need to purchase is a so called leisure/marine battery. This battery will be used to draw energy to power your utilities and devices. You don’t want to use the starter battery directly from your vehicle as there is the risk of it getting flat and you getting stuck somewhere. Leisure battery are also more suited to discharge smaller electricity inputs for longer periods while starter battery are developed to give a big electrical input for a very short time to start your car up. The leisure battery will need to be charged from the starter battery of your vehicle while driving (using a split charge relay).
The kind of battery you want for your van depends on your needs. Before purchasing your battery you will need to do some homework to find out how big you need your battery to be (more here). In short, the more AH a battery has, the more devices you’ll be able to plug in for longer periods of time.
I decided to go for a 110AH battery, as it was the biggest i could afford within my budget. 110Ah should be enough for you to power LED lights a laptop and a phone charger for a couple of days if you are sleeping off grid.
Before you purchase your battery you will also need to find a place for it. You will need to check the measurements of the battery keeping into consideration that you will want to fit it in some kind of box. Most people like to fit the batteries under the passenger seat, however mine didn’t fit, so I had to fix it behind the passenger seat.
I got mine from Amazon, however you can also find good deals at Tanya’s batteries and on Ebay.
SPLIT CHARGE RELAY
A split charge relay system will allow your leisure battery to get charged from the starter battery while driving. A split charge relay will automatically connect the leisure battery to the starter battery while the vehicle is running and automatically disconnecting while the vehicle is off. There are different kinds of split charge systems out there (more here), however i have found the split charge relay the most convenient solution as it doesn’t require any manual switching. You can find ready made split charge kits here and here. The kits will come with everything you need to install the split charge which I’ve found very convenient, especially if you are new to the business.
Those two pieces of equipment are the basis to both simple and more complex van conversion electrical systems.
