I'm familiar with solar and 40 watts sound about right. Example with my first 120 watt panel hooked up to a pwm controller i get about 6 amps of charge power. 14.4 volts x 6 amps = 86 watts, extrapolated that would be about 43 watts for a 60 watt panel. You never get the full output of the...

a 12 volt danfoss compressor fridge when set to 40 degrees comsumes 27 amps in a 24 hour period. When i try to run my fp430 edgestar 12 volt fridge as a freezer set to 0 degrees, I couldnt even run it 1 day off of my 75 ah agm battery and 120 watt solar panel. But at 40 degrees it ran 24/7...

You probably need to look into the flexible solar panels. youtube has videos on how to install them on boats and rv's. They are lightweight and can bend to the shape of your roof. There is probably a way to mount panels on your roof. I see some people just velcro them to the roof and then take...

the optima red tops are mostly for engine cranking. The blue and yellow tops are for deep cycle/cranking but there main weakness is all of them have low AH ratings. The biggest one is about 80 ah. For your use I would recommend to get at least a 100 ah battery, myself I prefer agm because they...

solar charge controllers only work with the solar panel. the 2 wires from the panel go into the controller , then 2 wires go from the controller to the battery. Once you get home you can maintain your battery with a 2 amp trickle charger you can plug in the wall. But you can always keep the...

As far as 12 volt fridges the danfoss compressors are pretty efficient. i had the edgestar fp430 and when i set it to 40 degrees it comsumed 27 amps total in a 24 hour period. The ARB uses the same compressor but has thicker insulation. But if you have the space seriously consider getting a...

Thats alot of money to spend for a mppt controller. Unless you have a massive panel on your vehicule (200 watts or larger) you wont get a big improvement over a many times cheaper pwm controller. 25 amps is alot of power thats equivalent to 2 x 250 watt solar panels at midday. That kind of solar...

I got 3 vents on my roof, 1x 14 inch and 2 x 9" and i actually cut another 14 inch hole on the roof to install another vent because the other vents werent getting the job done. The 14 " has a 5 speed vortex fan that can run fwd or reverse. The vortex fan while cheaper than the fantastic fan it...

though this is an older thread, i like to add more about swamp coolers. I do use one in my astrovan to keep cool and they are quite effective but they wont cool down the entire van but will keep a small area cool. I'm in california where it is always sunny, so even in the winter as soon as the...

Yes you can connect the sunsaver wires that say "battery" directly to the battery or a fuse box that has wires going to the battery. The controller has to sense the battery voltage to know if it has to bulk or float the battery. You dont need any diodes which will block the controller from...

for panels just get the largest panel you can afford instead of trying to hook up multiple panels. On my small astrovan i was able to fit a 240 watt panel on the roof and it has served me well. After expierencing the power of 240 watts, i would never use anything smaller. With a 240 watt panel...

on my solar system I use the xt60 connectors. they are small easy to hookup and remove and relatively inexpensive, you can get 10 sets for under 10 dollars. The only drawback is you have to solder the wires to them but its relatively easy. I used powerpoles before but i dont see the advantage...

inadequate especially if you get any cloudy days. I have the 43 quart edgestar. I have been running it nonstop 24/7 off of solar power since I got it about a month ago. It's hooked up to a 75 amp hour 12 volt agm battery, that is connected to a 120 watt kycora solar panel (rated 7.45 amp) on...
