Designing a 12Volt system Where to start? Well we start by deciding what sort of 12Volt stuff we’d like to have. It doesn’t matter if it’s an off-grid cottage somewhere, or a small camper-trailer – the process starts off with that same key question – what do I want? Without answering that question first, it’s […]

 Parallel, Series, Shading and Diodes   This is a subject that repeatedly comes up in debates, we often have solar panels in parallel, and adding diodes into the chat seems to fuel the confusion as well. And aren’t blocking diodes built into all solar panels these days anyway? Or is it in the regulators? And […]

12Volt Devices There are so many new 12Volt appliances and devices that are regularly added to our range of choices that it’s hard to keep up sometimes. This list will therefore remain a moving feast, and I’ll update it as new 12Volt stuff becomes available. The current draw (in Amps) of 12Volt devices will typically […]

Cables and Volt-Drop A cable is such a simple thing – so what could possibly go wrong… go wrong… go wrong… After all we’re just connecting power to our 12Volt stuff – it’s two wires, one positive, one negative, pretty simple really. Well it is and it isn’t. DC Systems It’s certainly true that in […]

Electrical Basics Volts, Amps, Watts and all those other things This information is on a need-to-know basis, and if you plan on getting the best out of your 12Volt stuff – you need to know! Fortunately the 12Volt equipment that we use for camping and caravanning is DC (Direct Current) and that simplifies things a […]
