rixhard, use a volt meter to confirm which is correct 12.7 or 11.4 or something else.

couldn't FULLY charge! could not respond to simple questions in this ole thread, trial and error found extra batts not the answer to how many more batts!
Oct 25, 2017 13:36:22 GMT -6 tattoo said: The answer to my question (how many more batteries) is NONE... The 4 6v batteries that I had to start with, with the 5 100w panels and a 40a CC... For it to work correctly...
When I added the 2 additional batteries the 5 100w panels I had they weren't enough to keep them charged fully with the power I was using 24/7.. So I added 3 more panels for a total of 8 100w.. Now it's working perfectly with my 40a CC from Renogy.....
Sometimes you need to take a day and read all you can about solar yourself.....

something ain't right, with a voltmeter the PV input should be = or slightly greater than batt voltage when charging. Connected 20v indicates either the batts are FULL or not charging.
Beside disconnecting the panels and then the batts and reconnecting the batts and then the panel, I'd try the return.
You can always connect the panels directly to the batt and then monitor batt v, you become the controller and disconnect @ ~15v and at night!

there is the SRNE (rover) version and the EPEVER (tracer) version, they seem somewhat similar. i tried the epever version when I had the excellent viewstar CC. I really like the grape solar 40a BT from homedepot, it has BT built in @$55 it is hard to beat the features, epever has a bt and wifi dongle for the app or pc software.

pv and batt both slow flashing is float see page 12 www.renogy.com/template/files/Manuals/Renogy-Wanderer-30A-PWM-Solar-Charge-Controller-Manual.pdfI'd disconnect the panels, then the controller and reconnect batt then panels, and hope straightens itself out. Keep probing either the input PV or batt terminal when the sun is shining, the controller will let max solar power charge the battery up till batt v is 14.8v (flooded), (temp corrected, higher in the cold and lower in heat), Then the controller limits solar power while maintaining 14.8v for 2 hrs and then goes to float of 13.2v (flooded). I would not use a inverter via the 'load' terminals of the controller.

A $50 controller and the app and ya got data, if ya don't like data so be it
The app be free!
adobob, I'll send a message via this forum.
in these sub freezing temps it is nice to check the low voltage of day without going outside and opening the garage it is simple and not stupid unlike the stupid and not simple approach, free and easy. After a week of more away from home it is easy to see daily low voltage for each day to check on the system. Haters just hate how easy and cheap it is, so be it.

here the voltage/soc for 'marine deep cycle' their chemistry can be different than 6v golf car batts. So your morning reading might be higher than 70%. Note: Estimate, approximation, 'only estimates', ...

CCA is different from MCA, CCA is cold cranking amps @ 0F while MCA is the same test but at 32F and should be higher. Most often on quality deep cycle batteries these specs are not given and generally lower than starting batteries.
You did not answer what voltage under no load would be ~50%, so I will attempt to spoon feed ya, ~24.4v (no load)
after bed you were near 100%, in the morning ~70%.
Battery capacity is for storage to be used later.
Don't let surface charge fool ya, if ya don't now what it is look it up, this is a solar forum and maybe you should check out battery care info.

"This morning it was 24.74 but did not leave frig on.
Every thing good with fridge plugged in overnight 25.7 in am."
I'd keep the fridge on all the time, seems to charge the battery!
I believe you can get an estimate of the SoC for each of these voltages
What would be a minimal battery voltage that would rep 50% discharged?
When your new batts showed up you measured their sg and recorded and reported that? Then you put all through through a full charge with bubbles and measured sg, recorded this for base line in the future and reported? You've searched or asked the battery maker for the correct charging voltage, how often to equalize and what voltage, float voltage ...?

adobo, you will like the capability/programability of the app, many features, no documentation for readers.
