Hi
I have a solar panel set up on my van. I have a 100 Watt Solar Panel, a 20 AMP control charger & 2 x 6 volt deep cycle batteries T105 trojan. I have a 12 Volt Coleman thermoelectric wired into the batteries through the 12 volt DC and a fantastic vent wired to the solar power control charger!
The Fridge runs on 4AMPS p/hr and is 12 V so thats 48 W an hour. = 1152 watts for 24hrs
When the batteries on the solar control say 13 Volts and i connect the fridge to the batteries it doesn't even last 24 hours without draining the batteries.
I have done calculations to the best of my knowledge but i think the fridge drains too much power.
Please help advise me on what i can do to improve my system. I am currently living off grid in Mexico and don't have enough power to turn on my inverter as i don't want to kill my batteries. My food also keeps spoiling.
The batteries i bought were second hand and tested before use. I think this may be the problem. But please provide any advice you have to help me! Wound appreciate it so much. Cheers, Sami
