For about a decade I ran a basic pwm system at camp to power my rv/camper. A few years ago I picked up a 21` 5th Wheel to fix up, and I'm using the old camper as sort of shed. Throughout that the battery bank was typically flooded 6v GC2's in series/parallel. My camp is somewhat isolated, the...

Can get a bit of snow at camp, challenge accepted. (y/t short) Good fun, good chow, & some football. 500w polycrystalline array, Renogy 40a Rover li, Magnum Dimensions 1000w pswi, 4x tel 12-170fga agm bank.

Got a screamin deal on 4 of these AGM's. I have them in series for a 12 volt bank. The bat box is vented from inside the camper/rv, as I used to run 6v GC2's. Well I have two questions about these batteries I'd like some help & opinions with as these are my first AGM's on the system. First, I...

So I upgraded my off grid system in my camper/rv, and need to run a new ground to my inverter. The inverter is just a 1000w pure sine but I might upgrade that at some point. Either way it should have a proper ground. The ground to the camper/rv chassis is centered while the controller - inverter...

I am looking for a good link / resource to calculate the loss of power over a 30 - 40 foot wire run. Probably use 8ga awg. Thanks.

Alright one controller will run an array of mixed poly panels about 500 watts in parallel. And the other controller will have probably 400 watts of mono panels (4x 100's). Both controllers will be identical. Both controllers will be connected to the same battery bank. Does the second array with...

Hey, I am into practical & conservative off grid solar system maintenance & use. Looking forward to learning & sharing advice on solar before I expand & improve my system at camp. It's my peace of mind there. I started out over a decade ago with a few small hf kits, was an active member of an...
