My Solar Experience ...So Far...

Rbertalotto

Explorer
1998 Palomino Bronco Truck Camper
All interior lights replaced with LED
120w Solar Panel..Paid $149 last summer (Sorry, can't remember brand)
Morningstar SS-20L-12V SunSaver 20 Amp Charge Controller
12V /size 27 deep cycle wet battery bought at Walmart early last summer

This past , three day weekend.......Southern New Hamshire....on the edge of field , in shadows at 5pm.....First day sunny, second day overcast all day, third day sunny....DaytimeTemp 70,80,70....Evenings 38, 45, 43

Electricity Use:

One LED reading light every night for two hours
One LED overhead light for an hour in AM
Refrigerator on Propane at all times with two 4" box fans running constantly
LapTop running off 1000w inverter to play a movie first and second night (3hrs each viewing) and then to charge laptop....left plugged in all night
CO2 / Gas detectors

Set Up:

10g wire, 10 feet from solar panel to controller
10g wire, 3' from controller to battery
Bogart Trimetric battery monitor

As I left my house, Trimetric was showing battery at 100% charge with 13.8V

first night the heater ran every 15 minutes to keep camper at 65 degrees. Watched movie, read a bit......in morning, Trimetric showed battery at 72%
Left camper at 8am, returned at noon and battery was at 100%

Second night, repeat of first night.....In morning battery showed 78%........Left at 8am and returned at noon to see battery at 97%.....returned at 4pm and battery was at 100% (Cloudy Day)

Third night, no movie.....read for 20 minutes....early to bed...Heater every 20- minutes or so.
In morning, Trimetric reported battery at 80%......By noon it was back to 100%

Never started the generator all weekend! Eveyone else at the event was running generators 3 hours in AM and 2-3 hours at night.

I can't tell you how pleased I am with my system....I never expected a single battery and a single 120w panel to work this well..........I'm a solar believer!

Excellent! Love hearing about ditching the generator and getting solar. Im impressed that one battery handled it also, I figured the heater fan would have dont more damage.

Nothing like camping all weekend and not hearing a generator. Now if we can just convince everyone else to copy or just need to go where no one else is.

Very cool, I'm also very pleased with my DBS and 100W solar. 120 is better, or as much as you have room for. I am running a fridge as well with no problems. No movies, but HAM radio and it is great.

Thanks for the 'real work' write up. Its very helpful.

Are the two box fans and the heater loads on the system?

Yes, two box fans and ALL electricity usage was on the single battery. No other power available.

A total 12V 3 day weekend!

Nice, Roy. Sounds like you have a good system going.

Remember that the full reading of 13.8v is most likely a surface charge. That battery is probably actually full at 12.6 to 12.8v at best. I have a pair of them and that's nominal for flooded maintenance free batteries.

Nice to hear that the 10-gauge from the controller to the battery wasn't much of a choke on the voltage. The short distance helps.

Where'd you hear about the Trimetric battery meter? That's the final component I want to acquire for my similar system, cause HandyBob said so! lol.

Congrats on your successful installation!
