<span class="highlight">Solar</span> or not

I just completed a round Aus trip.

Have a single battery in the van and a second battery in the truck that runs a freezer full time.

Free camped most of the time. Had a genny with me but the Solar panel coped very well, didn't start the genny the whole trip. The solar panel is linked to both the battery in the van and the one in the truck. The longest time in a free camp was 6 days.

So I find that the single battery works for me.

So long as you can put the charge in during the day Brett, for your minimal needs one battery would meet your electricity needs.

In our previous camper, we ran a small compressor upright caravan fridge and lights from a single 100 ah battery charged by an 80 w solar panel put out when we stopped. A larger panel as are common now would have been better due to the times of day we put it out. With the camper we couldn't roof mount it for during the day while travelling. We toured in fine weather.

I just faced that choice again. Have been running 2 100 aH batteries in the camper trailer charged off the car alternator. That was enough to power our modest kit for around 6 days. With the new CT I decided to go the same route. Certainly solar panels have come down a lot in price but I don't fancy the packing and placing routines.

If you're only going to be stopped for 3-4 days max, then what you have will be fine..

Make sure it's properly setup to recharge off the alternator...via an isolator and you're all good to go..

How big is the battery ? If it's smaller than 100 a/h, then a solar panel will help..
