Somewhat comparable to a vehicle starter relay, the solenoid is a big electrically operated switch. The simplest battery isolator is nothing more than an electromechanical relay. It used to be there were just two kinds of isolators now there are three. At the same time, the isolator allows your house batteries to charge up by drawing on your chassis or tow vehicle alternator.
Without such isolation, your house battery and SLI battery will seek to maintain the same charge level-and if that’s too low to start your rig, you’re left in the lurch. The RV had “stolen” power from the truck battery, leaving us wandering around with a set of jumper cables, looking for a hot jump.īattery isolators do just what it sounds like: They isolate your RV “house” batteries from your vehicle’s SLI (starting-lighting-ignition) battery. After our first night on the road, a chilly one where the furnace ran during the night, we found we couldn’t start the truck up. Thank you again for the calculator resource.On one of our earliest RV adventures, we learned the hard way about the importance of a battery isolator system. I could enter each item separately to get amp hours then total the amp hours at the end. What is that compared to 200 AH at 20-Hr Rate? Would this be sufficient for my setup? The calculator shows I would need a 216 AH battery running all items for 6 hours. Any suggestion on getting a better feel for how many AH I need in my Deep Cycle Battery? I am looking at one that says 389 Capacity minutes. With such variables in frequency of usage how do i figure the battery needed? The calculator, which has helped me a lot, figures I am using all DC 12volt items the entire time which is not the case. My lights I will use only when it is dark and when I am awake, the pump is only when I turn the water on. 9 LED 12v lights, A 12Volt Water pump, DC plug/USB Charger/Monitor Combo, and another USB/DC Charger. I have totaled my setup that I am building in my Cargo Trailer Conversion to be 16.3 Amps. I run a small fridge led lights all around and basic charging necessities iPad etc.Īll the gear and no idea!!! Is my favourite saying….
But I would still like it set up to work as it should.
The 4×4 drives around enough to keep the batteries topped up most of the time. I would like to go camping every month but the reality is 2-3 times a year for only weekends away and 1 week somewhere special.

Lastly, trying to fit a square peg in a round hole, what if I was to get a manual battery isolator to split the batteries back to 105ah then just switch the alligator clips between batteries, a bit of stuffing around but wil his charge the batteries fully? Also I’m looking at 2× 80w solar panels (160w) foldable with a regulator for each can I plug these two panels together (dual Anderson plug) or will the two regulators confuse each other. I purchased a10ah smart battery charger, it was half the price and I got a bit excited, my question is will this fully charge these batteries eventually? I realise that 10% amp size for the charger is the recommendation. From what I have learnt by reading all of the post that means I have 210ah and a 12 volt battery bank. Hi Tech, I have 2× 105ah batteries in the tray of the ute, running parallel, using a red arc dual battery system which seems so far keep these batteries topped up, using HD welding cable.
