The group name is using DIY Solar with Wil Prowse but it doesn't seem legit. https://www.facebook.com/groups/352775812853374

Thanks for the replies. Wintertime is the easy part down here in S. Louisiana. I have a Buddy propane heater and also bought a diesel heater but never had a chance to get it going before winter was over. I may add more solar panels but I'm learning to live off my 600ah LiFePO4 and once I get...

Bump. Bueller, Bueller? :P

Bump.

In the past year or so, I acquired 2x 100ah AGM batteries as part of a Craigslist package that I bought ($400 for NIB 3x 100watt solar panels, Renogy PWM charge controller, MSW inverter, cables, wiring, and the two batteries). I'm not using the charge controller or MSW inverter. I have 1,200...

Would it be a good idea to put circuit breakers between each battery bank and the busbars? Although it would be easy enough to disconnect one of the banks and the other two would still be connected, to double-check charging, resistance, etc. on each bank, right?

I have them more like the 2nd diagram now. I saved the images and may look at doing the 3rd diagram in my re-do. I do have enough wire for that.

Title should be "... Opposite Diagonal Ends?"

I have one battery bank with six 12v 100ah LiFePO4 batteries. I have two solar arrays (600 watts each) going into two Epever charge controllers. The system works but I'm getting ready to move some things around and add some mini-circuit breakers (replacing older inline audio type) and a DIN...

Update after a couple of days of changes to meter -- it's showing 400AH in the top right and full bars on the battery icon, but still not up to 14.4 volts. The first three pics are from the past two days, the fourth pic from today.

Update -- It has been a month and I think there is still something wrong with the settings. I kept it set at 100AH since I have 100AH batteries but I have four of them so it's a 400AH battery bank. Almost always, it would show 100AH in the top right (meaning 100%) even though the voltage was...

I installed the 1,000 watt inverter on 11/14 with the supply (+) line going to a 150 amp breaker so it's protected and would probably trip the breaker if I pushed it with the microwave and something else running at the same time. I also ordered 300 more watts of solar panels since this is my...

I have a 3,000-watt 12v to 120v inverter wired into my 12v battery bank now and only using the 120v outlets for now. Since the 3KW has a 30-watt standby power draw, I also have a 1,000-watt inverter that I wanted to wire in as my primary inverter and only turn on the 3KW when I need to run...

After more than a week of this battery monitor running, it is performing reasonably well. I'm guessing it's not 100% accurate but probably over 95% accurate. Of course, out of the several battery voltage meters I have on my battery bank (two charge controllers, inverter, 12vDC fridge/freezer...

Slowly learning this thing, notwithstanding the Ikea-ish instructions. I added a couple of more solar panels and got my battery bank back up to 14.4v today and the meter shows it at 100% now. The instructions alluded to getting the batteries fully charged or discharged and starting from there...
