The most common phrase I repeat when talking to motorhome and caravan owners about their electrical system is “Battery voltage is NOT a good indicator of the battery charge state”. The idea that there is a direct correlation between the voltage across the terminals of the battery and the amount of energy stored inside is […]

If you are building a motorhome or even buying one, have you considered what voltage the house system will run? Most people automatically assume that 12 volts is best – because … well cars use 12 volts and it never causes issues for them. If you are building or buying a motorhome, I urge you […]

This is the second (and final) part of my introduction to basic electrical theory – for owners of motorhomes and caravans. In this section we will look at watts (and we all know that solar panels are rated in watts) and also the connection of batteries in both series and parallel. But before we launch […]

Presented here, in a very easy to understand format, is basic electrical theory. This is the stuff that I learned in my first year as an apprentice electrician (and that was just after they invented digital watches). This basic knowledge is an absolutely essential grounding if you are to have any hope of installing, repairing […]

240v fridge or a low voltage fridge for your motorhome or caravan. Yesterday I was asked for my advice on the purchase of a refrigerator for a motorhome. Under consideration were a 240v 220ltr household fridge and a 12/24v 220ltr Danfoss compressor based unit (Waeco). I was asked to comment on the economics of each […]

Almost every motorhome and many caravans use an inverter. These clever electronic devices take the low voltage direct current (DC) power from our batteries and convert it to the same high voltage alternating current (AC) that our household sockets deliver. This allows us to have 240 volt mains power with us no matter how […]

Most people who have anything to do with solar power know that a solar regulator is necessary. Not too many of these people understand the exact function of a solar regulator or how it does what it does. For the purpose of this discussion and unless I state otherwise, I will be talking about the […]

As we travel, we often meet people who are in caravans and mobile homes. It always surprises me how many people continue to have issues with the electrical systems. In most cases the conversation starts with “why does my fridge cut-out during the night” or perhaps “my caravan lights go very dim by about 10pm”. […]
