Hello All
I have a camper which I am installing solar panels on to keep my batteries topped up when on none electric sites. i would like some help on the setup.
First I would like some advice on a sutable controller, i bought a MPPT30 from ebay but after researching (should have done before buying) I have found that these are not good. So I am still seaking a good controller.
My power consumption estimated is below.
TV = 25W / 4hr / 8.5 Ah
Phones = 14W / 2hr / 2.5 Ah
External LED lights = 0.5A / 2hr / 1 Ah
internal lights = 1A / 4hr / 4Ah
pump = 30W / 1hr / 2.5Ah
Total will be approx 18.5 AHr per day.
I only wish to be on batteries for 2 days max with out moving on. When on the move the batteries will be chaging from the vehicle 12 autonator.
What I have at present is
2 deep cycle sealed 110Ah batteries
1 100W back contact solar panel. Specs are Pmax 100Wp / Vmp 18.97v / Imp 5.28A / Voc 22.76V / Isc 5.69A
i may need to add a second panel if this is not powerfull enough
Any suggestions on a controller and is this set up is ok. I need to stay 12v as all the van runs on 12v
Any help will be great thanks
