It is not mean, it is fact. If you have 20 of the 12 volt 300 AH batteries you need 6000 watts of solar panels and a minimum of 6 80 amp charge controllers. Not 1 or 2 40 amp CC's, 6 of them with with 6000 watts of solar panels.
So something is very wrong with what you claim Just having 1 charge controller is not enough to even over come the self discharge rate. No chance you could have ever over charged the batteries to begin with.

charger controller?
i didnt buyed yet?
but if i do? i thing if better the highter of amper is much better? no?
i do have a wind turbine but is not install yet i rather expend more time to get some info
or i will damage my all things better charger controller a least 160A my wind turbine is
700 watts ...
im still im new to the solar windturbine and solar batterys?????
anyway
frist is to fix my baterys then i will move on the wind turbine....
and VOILA! (french expresion)
i will be really happy!
thank you!Leave a comment:

disconected all
i soones they drope i will calculated all that
my invereter is pure sine 1500 watts 12V
i have only one solar panel 80 watts
i will make a video doing on my problem so other people can get some help too
like me i was going to buy $150.00 on a 24v inverter of 400 watts
then somebody toll me that just to buy a 12v lightbuld and coenected directly to only one battery.? but is taking so much time to drope????
or ? i should go and buy the 24 v inverter puresine???
in ge it ???
que dolor de cabezA????
thanks again !!
looking forward:LuisLeave a comment:

inapropriate? sorry i didnt know??
im dsicharging my bateries with a lightbuld of 12v
hopely is ok...?
whats is the best thing to do?
do i have to buy a " 24v POWER INVERTER"
(sorry my english im spanish never went to school for english just spanish)
i would like to learn how the solar panels and bank of batteries work
in mexico cost of electricity is so expensive!
i just call a company for a new charger controller from germany 30A
Solar
Solarix MPPT ?010
i dont have yet but i will....
if you have any sugestion and how to line up my bateries in what kind of?
12v ?
24v ?
48v ?
and what brand of inverter do i have to buy?
sutf like that i will really apreciate and thank you to everyone
that kindly try to help me on my solar ...
and to help the planet heart
thank you to everyone!!!!!!!!!!!!!!!!!!!!Leave a comment:

Yep Astronomically Impossible came to my mind, unless every one of the batteries is open circuited, then i could understand it. I got a sneaky suspicion this guy got conned into buying a load of used batteries from a data center that were in a UPS. Quite common for telecom companies to look for a pigeon to pluck to sell there used batteries too because it cost them a lot of money and EPA paperwork to dispose of them.Leave a comment:

The hardest thing to get any understanding on now is his claim he overcharged the batteries.. ???
The word IMPOSSIBLE come quickly to mind if he was using ANY single charge controller.Leave a comment:

Sunking I agree with you 1001% That is why I have asked him the questions I have.. Each question is as important as the other, .You will notice he was asking about a "diversion load charger" That may indicate wind generator.???? I did note if he had a 40a charger at best it will just support battery self losses only.
We as yet have no idea as to what his loads are on the unknown inverter.Leave a comment:

Quite possibly he has received bad advice from someone - maybe the fellow selling batteries.
Luisito - if you can supply information requested the guys are willing to give you a hand so as not to have a second disaster.Leave a comment:

John it looks like he is using 20 of GNB S12V300. which is a 300 AH 12 volt battery made for UPS systems. He claims 20 of them for a 12 volt @ 6000 AH. There is no panel wattage he can run to support that much battery, at least not with any single charge controller.
It would take at least a 6000 watt solar panel array using 6 80 amp amp MPPT charge controllers to support that much battery at 12 volts, and no one who knows anything about RE battery application would use this battery, or use that much battery at 12 volts. It screams for 48 and 96 volt battery configuration.Leave a comment:

Luisito. it very hard to offer you a controler without knowing the following..
you using a solar panel array??? if yes what is total wattage??
you using a wind generator?? if yes its rated output,?
Do you have th e AMPHOUR rating of each of those batteries??
What size inverter you using??
What loads are you using on the inverter??
With regards to to batteries as you may have 20 of them a 40a charger is only ever going to put 2a into each one... enough to replace self loss in the battery.. with very little available to power an inverter..Leave a comment:

Those batteries you have are completely inappropriate for Renewable energy applications, and you configuration of using 20 in parallel is insane just asking to be killed.
What you have is batteries designed for UPS systems emergency Stand By Power. They are not made for cycle service. . At best they have maybe 100 to 200 cycles in them or less than 1 year service in a cycle RE service.
When you replace them by batteries for cycle service and sized so you only need 1 string.
I also agree with John it would be almost impossible to get a 12 volt battery up to 17 volts. Only way to do that is they are open circuited (destroyed). Take one out and measure the voltage after it has rested for a few hours. Bet it will be less than 12.6 volts. If so you now have an expensive boat anchor.Leave a comment:
