  • Post in thread: Off grid cabin solar build using some freebies

    Appreciate all the replies and links! I'm learning a lot. Here's some of what I'm taking away, the main things anyway: -It's ok to charge the batteries slow instead of a fast high charge. -Looks like the coffee maker should go, or at least not be used on the batteries. I have alternative ways...

    It's hot and humid here in the summer...AC is a wonderful luxury! I normally just run one 5000 BTU unit in the evening and through the night. It's about 2000' elevation and in a forest so it normally feel much cooler than at home, by 5 - 10 degrees. So yea I don't mind running the Gen...and in...

    One more question: My frig is an RV newer style Dometic that requires power to operate the ignition and motherboard/controls. I have a single AGM under it to run that and my RV-style lights throughout the cabin (on a separate DC subpanel and switch box). -Can I pull a 12V branch off a series...

    New member here. I have an off grid property in E TN where I’ve build a well-insulated 300 sf cabin (plus upstairs) that just has the basic necessities. I have a small 5k BTW window unit, coffee maker, tv+dvd player, few other small devices. I’ve been running everything off a 3900/5000...

    Great response! Interesting ideas. I will look at those items. The largest unknown to me was if it was ok to recharge slowly over a longer period of time. I have read that AGMs like a fast and high charge. So that is great news to me that a slower charge will suffice. I noticed yesterday that...

    Oh forgot, the inverter is a 48v so I’ll have to run batteries in series and parallel if I use all 8 instead of 4. I would like to toss the inverter and just get a 12v inverter but I hate to buy another one now. I already have 12v rv lights ran off a single 100ah AGM inside the cabin that also...

    I get it, you’re right on. Not going to run two ACs with the inverter and may not even be able to run one consistently was my thought, because I know ol Murphy all too well. I have a Gen switch I plan to install so I can switch between gen supply or another load supply, in this case...
