So. I paid the guy to wire up an Anderson plug on the car. An Anderson plug is wired right back, directly to the battery and is better than relying on the smaller wiring of the 7 pin plug. The circuit also has a relay box that automatically switches off the power supply once the car engine stops. The advantage of this is that you can park up for lunch at the top of the Remutaka hill, or stop at the supermarket and stay hooked up – the relay switches off the power supply, so it doesn’t drain the car battery.
The guy also had to alter the wiring in the caravan so fridge will still run even when the main caravan 12 V switch is off. There is some rule in the UK that you can’t have anything electrical running in the caravan while driving. While driving the car uses the alternator to charge the caravan leisure batteries in conjunction with the roof top solar panel. The fridge in the caravan is then powered from the leisure batteries. As a test I ran the fridge ran for 6 hours on the 12v batteries with no problems. This was however a sunny day test, so it will be interesting to see how the batteries cope running the fridge on a cloudy or rainy day.
