Imported RV electrics are often not fully compliant. Their owners often wrongly believe they are. They cannot legally be sold unless remedied.

Interconnecting batteries in parallel or series – here’s how and why
Interconnecting batteries in series or parallel is totally feasible. But its best to know how it works – and the limitations of each. Collyn Rivers explains.
AGM batteries for caravans – they are still worth using
AGM batteries for caravans, camper trailers, motor homes charge faster and deeper than lead acids and are more rugged mechanically and electrically. They have far less internal discharge. If initially fully charged, they retain 60% or more for over 12 months (except in very hot areas).
RV Alternator Charging Problems
Before 2000 or so most alternators produced 14.4 – 14.7 volts, and a few close to 15 volts. This situation changed in 2014 in the quest to reduce emissions. Reducing alternator voltage assists, but introduces problems if the alternator also charges RV batteries. This article by Collyn Rivers explains what causes these alternator charging problems – and how to fix them.
RV Batteries
RV batteries store energy from your RV’s or tow vehicle’s alternator and solar modules and grid or generator power via a battery charger. This article explains all about the many types of battery now available.
Caravan and Motorhome Electrics
Caravan and Motorhome Electrics covers every aspect of designing, installing and fault finding of the electrics in fifth wheel and conventional , camper trailers and motorhomes. The book explains how things work, and what they do (not what vendors claim they...
12 volts dc from 24 volts dc
Taking 12 volts dc from 24 volts dc can ruin the batteries in a 24 volt system. Here’s how to do it effectively and safely. There are two main ways. The choice depends mainly on the peak current needed: for example the plus 130 amps for a typical microwave oven limits choice to the equalising system described below.
Electrical converter problems in caravans – problems when used for free camping
Electrical converter problems in caravans result in flat batteries when away for more than a few hours from 230 volts. Here’s how to fix this. These converters are fitted to almost all caravans and motor homes worldwide. They are thus not suitable for RVs free camping.
