Hookup diagram? (1 Viewer)

[Adammully]

Hi all I've added a hookup point and distribution board to my camper I'm wanting to know what thickness cable people recommend from the hookup point to the board

Also how do I go about when I'm not hooking up to power my sockets with the solar panels?

If anyone has a diagram or a link to one will be much appreciated

Thanks in advance

Some of the electrical techies should be along shortly. I guess your post got lost in the mountain of them yesterday.

Solar is used to keep your batteries charged.

You’ll be needing an inverter if you want to power your mains sockets from your batteries.

If you’re going to power your mains sockets via an inverter you’ll be needing a large battery bank.

You will ned to say what size solar panels and leisure batteries you have so you can be advised if it is a suitable set up for powering your mains sockets. Using an invertor to power mains sockets needs a lot of battery capacity.

I can't comment directly Adammully but I find it useful to look at the "Similar Threads" below - often find an answer or link or something to investigate whilst those with the knowhow come along; hope you find something of use there meanwhile

One such post sent me off looking at the 12voltplanet website for ideas...

If you used the same rated cable as the hook up cable itself you would not be far away so 2.5mm sq would be well on top of the job in my book but I am no expert

If you want to power your 240v sockets when you are not hooked up to mains then you need a decent amount of battery capacity and an inverter, if you are starting from scratch I would be looking at a charger/inverter combo with mains backup or network compensation feature.

I have all the off grid set up and running at the moment I'm wanting to add the hook up system for when I go on sites for microwave and proper kettle?

Sorry forgot to mention I've already got off grid up and running at the moment just wanting to add the hook up system for when I stop on sites

Would you be wanting the EHU to be charging your batteries as well or just be a discrete power source used through 13A sockets? If the latter a properly protected 2.5mm radial circuit would suffice.

Bring the leccy into the van then to a consumer unit then to sockets. Keeping 12v separate from 230v is the easiest way.

What If I wanted to go off grid?

Nobody mentioned..... Use flex for any internal wiring unless PVC T+E can be securely clipped and can't move at all.
House type PVC Twin & earth can vibrate and break.

Off grid, it is best to avoid 230V. Most of what you actually need can be obtained in perfectly adequete 12V versions or by buying a 12V adapter. This includes lighting, television, phone & laptop chargers etc. Don't use electric cooking/heating appliances. A kettle on a gas ring will make a cup of tea almost as easily as an electric kettle.

If you've got a "must have" item like a hair dryer or coffee machine, you will need to spend thousands on solar panels, inverters, B2B chargers and lithium batteries to keep up with the demands.

You say your set up for “off grid” so as cmcardle75 says stick with it. We are also totally “ off grid” capable and when enough sun we only ever need to go into anti sulphate mode every few months to save the batteries (takes them to 14.3v).
230v telly, Humax box and many others have a transformer inline that drop them down to 12v anyway
