Van 12volt power supply
Permalink  

I recently downsized my van from a 2013 Jayco Discovery to a 2005 Jayco Freedom. The freedom had a centurion power supply, battery charger. It was useless as a battery charger & only had five 12 volt fuse outlets that were all used. A couple of lighting circuits were doubled up on fuses.

I removed the centurion & fitted a 240 volt 10 amp ctek charger, a ctek 250s dual regulator, & a narva 12 outlet  fuse block. I also fitted a shunt type amp meter so I know what load - charge is happening.

I fitted a 120 watt solar panel on the roof, & I have a 100 watt folding panel which I rarely carry.

I have a 100 a/h battery which is enough for a few hours tv, lights & charge lap top, phones, cameras etc. I've never seen battery voltage below 12.3. I charge devices through the day when there is solar input.  When the battery dies I will replace it with a 120 a/h.

Cheers Pete

 Hi David, the volt meter & amp meter are from jaycar. Approx $20 & $40. The amp meter is a negative, shunt type, all the charge & load has to go through the shunt. It is accurate with charge & load current, but zeros at -.3.   For $40 I can live with that.

Cheers Pete

My fridge battery was sitting in a plastic battery box, in the back of the car. The ctek charger was attached to the top of the battery box. 

It was sitting there doing one job, running the fridge.

I looked at power pack boxes. They ranged up to $800 and weren't exactly what I wanted.

I set about building one. A lot of procrastinating and a week later I ended up with a useful battery box.

It has two anderson plugs (one for the fridge), two cigar sockets, One usb socket.

Final cost was less than $200.

Great job - I must admit when I opened first photo I thought to myself; Öh! Crikes" He has made it out of metal - and I had that "How do I tell him quandary" - the subsequent photos however were detailed enough to qualm my initial reactions. Definitely a very pretty and professional job.
