Critique my proposed dual battery & solar setup

#62
Hi again Billolga and thanks.

I have been looking for some QUALITY USB units and so far, most are no worth touching.

But those, with the 3.1 amp output sounds a lot better that what I have seen.

Thanks again.

It is 1 and 2.1A. Should be OK. The tablet is a 10" Samsung Galaxy Tab.

This is the one I got to use with the outlet board in the cabin:
GI B 12V Bullet Dual USB Port CAR Charger Adaptor FOR Iphone 4 4G Ipod Touch | eBay

The GPS runs off the cig adapter and the two phones are running off USB (not at the same time). I bought one of these to plug into the cig jack in the front dash to power the GPS and possibly one of the phones at the same time from USB. It only puts out 1A on each port which is plenty for a phone.

Thread update.

The USB bullet I bought is useless. Doesn't supply enough power for most modern smartphone and tablets (an error about insufficient power comes up). However we bought another one from Target for $5 that does the job fine.

Further more I have been travelling with my wiring setup now for 4 months and have had no failures apart from one of the crimps on my Anderson plugs falling out of the lug because I didn't solder it in place.

Our one issue is that we haven't been able to put out our portable solar panels as much as we thought (lots of short trips and free-camping in town). So we have only had enough power to keep the fridge running, charge our phones once a day and tablet once every few days. I am going to relocate the solar panels to the roofrack once I have that built. The dual volt sensing VSR I bought has been working great and having a supply of electricity to keep us powered up has been amazing. We rely on our phones and tablets so much when we are on the road for trip planning, research, mapping/guidance etc.

Very happy I spent the money on the VSR and good cabling, and spent the time researching and installing everything.


(note: I re-routed the outgoing power from the VSR after this photo was taken as it was propped up against the aluminium coolant tank and I was concerned about it being dangerous)

I have found them great but had one pop the other day - HELL! - the expense!:eek::D

Only the top plug is 3.1 amp BTW - not the bottom one.

Apologies for bumping an old thread but i've found some useful information in here
Just wondering how it all worked out crankitupto11?
This setup looks pretty much how i'm considering of going, however battery will be under the hood and the outputs for fridge etc. will be in the ute tray. Anything you'd do differently second time round?
Is there any real value in doing the 12V DC outlet board through an Anderson plug?
Cheers!

On the subject of relays to cross between solar and main battery on dual input chargers. I've brought a redarc 1240 with solar and in the process of buying a relay I've found that no one makes a heavy duty 5 pin relay( I couldn't find one anyway) there are plenty of large ampere relays with little tiny cables coming off them which I'm reluctant to use because I don't want to step down in size. and there are heavy duty relays that are 4pin only. How do i get around this problem. Or is there a product I'm chaising that I don't know about. Cheers

I am not familiar with the Redarc unit but assume that it automatically switches itself for the best source of solar or alternator supply like the Ctek does ?
Or are you looking to do something different ?

It's only got one input cord that needs to be diverted with a relay. So no to your question about being like the ctec. I'm trying to find a relay with big enough cable to suit the 6mm I've run from the main battery to handle the 40 amps the redarc will be drawing. It defeats the purpose of running 6mm wire from the main battery to handle the 40 amps it will be producing to connect it to a relay with 4mm wires on it. Am I making any sense. I might be able to explain it in a different way.

Ah ok, so you have to manually select the source
Maybe check on the Redarc website or call them. I have heard that they are very helpful
