100 watt panel will give you 5 amps of charge power when the sun is overhead. In a good day it might put a total of 30 amps back into your battery.
A 12 volt fridge when set to 40 degrees might consume about 25 amps in a 24 hour period. As long as you have good sunlight where your at, you...
The only thing I have to add, if you have 1000 ah of lithium batteries and you drain it to 200 ah and then you charge it at 400 amps. Its going to take much longer than 2 hours.
You can charge it quickly to 90 percent at 400 amps, but then as it gets full the battery will act like a lead acid...
according to the battery website
absorb should be 14.5 volts.
float should be 13.2 volts
But since you will be using solar, just keep the float at 14.5.
With solar the absorb will finish too fast and go to float before getting a full charge. There is not enough sunlight in a day to fully...
a fantastic fan draws about 3 amps at the high setting, but it has 3 settings, at lower settings it uses a little over 1 amp. Sometimes you only need the low setting to move air.
LED lighting will work the best, I use the supernight leds, it comes in a roll of 10 feet, I only use 4 feet in my...
Its what I used, I had it for about 3 years running 24/7 365 days , its always connected to the battery so I can see the battery status at night. Power use is insignificant. From my use they are reliable.
It might be off be off by half a amp when compared with what my ecoworthy controller LCD...
you can get the opus btc3100 for 10 dollars more than the opus btc2400 (about 45) and charge the 18650 lithiums use in some flashlights beside all the aa / aaa.
Its the charger I have and used it to charge 100's of lithiums, charges discharges measures capacity of batteries. Its the best...
thats a total of close to 440 amp hours. If you deplete them all the way down and wanted to fast charge them at about 100 amps (max 50 amps per battery) even with the engine running it might take several days. You can get it to 60 percent in about 4 hours then the absorb phase will take 10 hours...
in winter you get less amps out of your panels. My 240 watt panel connected to an ecoworthy 20 amp mppt gets me about 9 amps in winter about 12 amps in the summer. Thats with full sunshine. In cloudy conditions you might get 5 amps. Barely replacing what you used the night before.
With a 100...
I have to agree that insulation is the only way to make AC work in a camper environment. Its just too much sun hitting the metal/windows of the camper to be overcome by a small AC no matter how powerful.
Myself I rely on swamp coolers to keep cool and they are a magnitude less powerful then...
8.5 amps sound about right for 200 watts of panels and this time of year. You might get 15 amps on rare occasions when the sun is straight overhead and your batteries are below 50 percent and brand new.
I got the same ecoworthy controller connected to a 240 watt panel, in the summer I max out...
my observation on lithiums is that they perform similar to lead acid while charging. I have a 94 amp hour 3s lithium battery (max voltage is 12.6) it does have a BMS circuit that will shut off charging power to it after it reaches 12.6 volts or one of the 3 cells reaches 4.2 volts. As long as...
I just used a rectangular pie pan I bought at the dollar store and drill some holes with a "step drillbit" I bought at harbor freight. Anything that is the proper size/shape for where you want to mount it will work. Plastic will work also. As you can see I like my fusebox close to all my...
Get a small efficient laptop or even a netbook. I can use my netbook 24/7 if I wanted, they are very efficient. My large 15 inch laptop uses up to 7 amps of power, I use that only when the sun is out.
For a meter I recommend you get LED, thats what I have 90 volt 30 amp combo meter (cost about...
100 watt panel will only get you 5 amps of power whether you use pwm or mppt controller. For 100 watts a wincong 10 amp pwm controller (less than 20 dollars) will work.
Pwm controller will work on low voltage panels (20 volts) and you can use them also on higher voltage panels without damaging...
for a 100 watt panel you can get away with using a 10 amp wincong pwm controller, they are less than 20 dollars. I use one for about 2 years on a 120 watt and even on a 240 watt panel. I think the 25 amp morningstar is too much controller for your needs. I dont see that kind of amps even on my...
60 ah battery might run fridge for 1 day, you want to not drain your battery under 50 percent, which for that size battery is 30 amps.
I had a 75 ah agm battery and when i had bad weather it never ran my edgestar fp43 fridge more than 1 day. Once your battery gets under 12 volts, your under 50...
100 watts should be good for your limited use. The laptop will probably be the power hog. They can use 6+ amps of power. If you instead use a netbook, you can use that all night long without draining your battery, its what I use.
100 watts will give you about 5 amps of charge power when the...
leaving the lights on one time shouldn't kill a 6 months old battery.
About 3 years ago I bought a use battery and several month later left the lights on in my van all night long. In the morning the battery was completely dead. I have a 240 watt panel on my roof and was able to connect the mppt...
I agree about the insulation, that is something that is overlook but will work extremely well. In my astrovan I insulated the shiat out of it, roof, windows. floor, sides and I built a sliding door divider between the front and rear of the van. Parked in the sun with all windows/doors closed the...
goal zero is a 33 ah agm battery powerpack. You can just buy a comparable agm battery (about 70 dollars)and maybe a small 400 watt inverter for 50 dollars. 400 watts is more than enough to power most ac fans. Building your own would be alot cheaper than going namebrand. Some 12 volt jump packs...
