well im thinking i would only really want to charge the aux battery wouldnt i? i thought the Pianha battery management system would stop the starting battery from going flat? Im not 100% sure how it works to be honest, so if you have any insight, thats would be fantastic.
Yeah 80w solar panel, bummer that heyi wonder what the reason for max 50w is?

I have an Anderson plug connected directly to my aux battery (via 13mm2 twin core cable with a circuit breaker at the battery end) that is hooked up to the camper to charge the camper batteries when driving. I plug my regulated 120w solar panel directly into either the truck or trailer when camped up, have a fridge in the truck and power for lights and water pump in the camper. Works for me.
Time Marches On .....and on ..... and on
Yes you should only need to charge up your auxiliary battery with the solar panel. I was just going by your first post.
The basic operation of a dual battery system with isolator is, when the engine is running both batteries are electrically joined together, this enables the alternator to charge both batteries.
When the engine is stopped the isolator, isolates the batteries from one another. This enables you to run your accessories from your auxiliary battery (such as fridge, power for lights to your camp or what ever else you would like, (just connected them to the auxiliary battery)), without running the risk of flattening your starting battery.
With you solar panel you can just connected it to the auxiliary battery.
If the solar panel is not going to be permanently mounted on the vehicle, then you could make up a short lead, one end with the anderson plug and the other end with some good quality alligator clamps.
This way you could connected it to any battery you wish.
The regulator inside the isolator will only be able to handle 50 watts (about 4 amps) if you connected the 80 watt panel (about 6.5 -7 amps) it could burn it out.
Hi i was thinking that you should conect it to the main start battery that way it will charge the main first whitch i think is the most important and then link the main to aux through the isolatior and charge the aux just like it does when the cars running
but when im stopped with the fridge running and light, the isolator cuts of the main battery to the aux battery.
So the main starter battery cant go flat. Why would i need to charge that?
I mounted my portable air compresser under the hood with a quick connector, Easy job, works great
What's a quick connector mate?
