I am back after a vaction and working out some issues on this truck but thats the fun part of building it.
I figured I would post up some info on the solar panel system. So far it is working perfect, the other charge controller was either defective or too much for my system, it was made for up to 150 watts and 30 amps, the current charge controller will handle 75 watts and 7 amps but it is maintaining my batteries so much better then the other.
I started with my Engel 45 fridge cold using 110v power and both Optima yellow top batteries fully charged. As soon as it got daylight the solar panel started charging and I switched the fridge to 12volt power.
mid afternoon and the solar panel output is great, batteries are still fully charged.
Solar panel output , bright sunlight, mid afternoon
this is the charging voltage
And this is the battery voltage
I have turned the fridge all the way up and when it gets dark I will turn it down. I want to see how much drain on the batteries it will have overnight and if the solar panel will be able to recharge them back fast enough to matain proper operating voltage.
another thing I put on is this nifty table from Thule. I think it will work pretty well.
