Great informative post on home solar for sure.. In the large solar array business it steady for the foreseeable future. Batteries are becoming more and more a part of the large solar farm to help offset the low output at night helping to keep the power supplied constant.. as for texas heat. get...

Yeah saw this .. way above my paygrade. looking for a easier way to make it happen.

you can buy good quality "preowned" solar panels at santan solar on there website.. just add dot com to santan solar to get them. They have some new overstock panels, some that have minor damage like the frame got bent or one panel scrapped against teh glass on another one making some marks that...

can you plug battery charger to 120v power.. if so do that.. no need to suffer if not needed.

best way is to plug rv power cord in with adapter or just use extension cord to battery charger and let it rip..

how far can you extend the wire on bluetooth dongle on the JDS bms controllers?/ i need to put them up higher and est about 4 ft of wire needed.. I was just going to cut the wire and add the extra between plug and receiver.. same gauge or larger ?? I was going to use butt splice for teh most...

Excellent video.. When i was in HVAC class in the 80's the roof mounted water solar heating systems were still in use from the Carter years. We did something along these lines but using 1/2 copper tubing, (it was much cheaper then) as it was the only good quality tubing we had at the time...

roger that on the breaker.. that is on the list to upgrade.. seldom pull more than 20 to 30 amps..

So I added another battery 230 amp hour to my existing 230 amp hour set that's already wired I'm thinking if I put the black wires together since the neutrals are both on the same end of the battery now and then where the red wire comes across the terminal on the battery to the left just cut...

FOR sure not rubber.. alum only.. some fiberglass composite wall board type roofs might work but rubber is a screw down to wood for sure. :) the rubber is just floating or with a not so strong glue under it..

I can tell you from experience if the VHB tape is installed correctly it is going to take more than like 75 mph winds to remove them from alum surface.. I would image it seem that is not enough but the place in oregon that has installed 100's if not 1000's by now on all sorta roof using just VHB...

So tried the xiaoxang app, (little elephant) and it now seem to be working??.. it look weird with nothing hooked up but the BMS so next stop of to put some wires on to BMS and put some volts to with the solar system..

So i tried removing and replacing wires,, checking on each pin of plug volts was good.. tried both apps and while the bluetooth work fine i get no voltage info to load.. so it a fricken another piece of chinese crap.. do to my time constraints not able to get replacement so looks like it might...

LOL.. yeah just test setup the little red wire..on the B terminal.. The cells tested at 3.28 each.. did not check on pins will have to do that next.. will try the JBD app as well to see if it will be better... I did try the plug on my other JBD bms that is working fine and got one blue bar...

So I hook it up to my other working JDS BMS and only get one blue line that shows voltage the other three just are barely showing and I get low voltage alarms so I don't know what the heck is going on.. I wiggled all the wires all the terminals are tight so I don't have a freaking clue what the...
