They have dropped, I hadnt noticed. Now selling for $143 on Overkill's website. So I guess my price will be $125 each.

Bought two 4S BMS's with Bluetooth but didn't end up using them. See images. Looking to get about $125 each. Buyer pays whichever shipping they prefer. Located in Dallas Texas area.

Well, that was the most frustrating troubleshooting ive ever done in my life. I was verifying voltage at the tips of the MC4 connectors, but as soon as i plugged them into the ports on the unit, the voltage would vanish just 2 inches away. So i put my charger leads right on the PV board inputs...

it shows voltage at the MC4 connections that touch the PV inputs. I guess i could open it up and see if there is any voltage at any point downline inside the unit? Doing this out in the Arizona desert in the heat with biting flies.. not fun.

Yeah polarity is good, my volt meter confirms it, and when i hook up my panel directly to the PV inputs, you cant really get it wrong - male to female, female to male.

I have a brand new MPPT LV6548, having had good experience with the 24volt version. I just set up the system today with 4 SOK 100ah batteries in series. Batteries are fine and the MMPT sees them fine. I dont have any utility power source, but the AC out is blowing a floor fan using battery...

perfect. thanks y'all!

I just bought a small 6cubic feet solar refrigerator (12/24v) that I need to build a temporary rig for. It pulls 53watts. Will be using for 2 months in Dallas where we get a fair amount of sun in the summer. My plan is to run (2) 240watt poly panels (used ones from SanTan solar, already...

Fortunately I am doing this system under a "no permit required" situation so i dont have to follow all codes, but I don't want to kill myself either. And as safe as I try to be, on my 24v system I caused a short across battery terminals TWICE, just by being sloppy. It was enough to cause small...

I am building my first 48 volt system, and I hear Will's comments about getting shocked and being careful, but im not finding much information on how to put safety in practice. Does any have a resource or list of DONT's when it comes to working around 48volts? When a discharge capacitor is...

Update: looks like the input posts had loosened themselves due to road vibration. Tightened them and the voltage went back to normal.

I bought a 12volt load center / fuse block from Amazon. the voltage going into it from my 24>12volt converter is 12.3volts consistently. But When I put the multimeter on the connectors, I get about 10.8 volts. None of the wires are getting 12volts from the bus. Is this normal? My Iceco fridge...

Interesting. I ordered 16 cells not too long ago from Aliexpress and then they RAISED the price a few hundred dollars during the worst of the supply chain issues. Now we have these cheapies. I read the warning, but it didn't say the batteries were fake/counterfeit, just that they were grey...

So with this setup, Do I just take the bottom positive and just run it to a pos. bus bar, that then sends out two pos. lines - one to my MPPT2424 in, and the other to the 24>12volt converter? Sound right? And run the top negative to the MPPT neg in? Thanks in advance for help!

Excellent job SolarOhio! Love it!!!
