over charger batteries???? 12v now is over 17v??????:(

[Mike90250]

I am going to LOCK this thread. It's going no-place.

Luisito - if you can get someone local to help you with your translations, and start this thread again, we will try to help.

But we need the following information about your gear and setup.

Loads: Size from the appliance nameplate and hours daily.
150W 4 hours
1/2 hp 90 minutes

Charge source
a) PV panels, the Vmp and Imp off the back of the panels
b) spec from AC charger or generator

Batteries:
a) voltage
b) AH capacity
c) quantity (how many batteries in the bank)

System:
a) voltage
b) inverter input voltage, and output voltage and watts
c) charge controller

ANOTHER problem?? solar panel

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.

when i disconected the cables from the charger controller
i dont remember if i insulated the cables so didnt touch together??

now i conected the old charger controller
i not get in any kind signols
my voltemerter i should read any numbers right?

[Sunking]

so there is something wrong with my batteries...?

You could say that, you have 19-2/3 too many of them for a 80 watt panel

i dont have 6000 watts on solar panels...?

With the amount of battery capacity you have, you need 6000 watts of solar panels to keep them charged.

With an 80 watt panel, all you need is one single 12 volt 80 to 100 amp hour battery, and a 10 amp charge controller. With that setup you can power your computer for about 2 hours per day and that is it. So what I am telling you with your 80 watt solar panel is it is not even large enough for just 1 of your batteries. You would need a 300 watt panel for each one of your batteries, or 6000 watts to run your 20 batteries.

??only one batery....

You are joking right? 85 watts? At 85 watts the most current you can generate is 7 amps at 12 volts. You need 6000 watts of solar panels and 320 amps to charge your batteries with.

With what you have now is not even enough to charge 1 battery you have now let alone 20 of them.

so there is something wrong with my bateries...?
i dont have 6000 watts on solar panels...?

is only 85 watts
i suppost to buy 2 more maybe 175 watts this year,,,
any sugestions?

solar panel

I will ask this for the last time. How many watts is your solar panel array?

[luisito]

question? this bateries are not for solar?

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.

they have been disconected for a few days and didnt discharge yet??
im still weating for my 160 amps controller

if my bateries are ok i will be selling this bateries

[luisito]

thank you

You need a charge controller that performs 3 stage charging, Bulk, Absorb, Float

During part of the charge cycle, 14.5V will be fed to the batteries to "push" the charge into a 12V battery. This is NOT something you can do by hand with a voltmeter. (well, if you could, you would not be here asking)

You should let the charge controller manage your batteries for 3 sunny days with no loads on them at night, that should fully charge the batteries.

Then you can use them overnight, if the are dead (below 11.5V ) in the morning, the batteries are either damaged, or you don't have enough capacity for your loads.

im still waiting for my charger controller
i bought
160 AMPS
MAYBE one week i will get my charger contrroller

you think
i should config my batteries for 24V????
looking forward: Luis

[Mike90250]

question?
to fill the baterie how much they to be?
13v or 14v?
mys batries still disconected when i get my new charger controller i will coected
all my bateries
how can i know if my bateries are damage???
thanlk you!!

hi

Need a lot more info than that. Beginning to sound like he is just making stuff up, as he will not answer any questions.

what kind of info?

[luisito]

i just bought 160 A charge controller

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.

hello???

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.

sorry my english
but i dont understand???
what do i need to do?
to config my bateries at 48 v
so thats mean i have to buy a higher charger controller??
whats a mean MPPT???
Thanks

Please tell us again, the part # of your batteries, as something is very wrong, as you are describing an impossible system

[Mike90250]

hi i have problem?
i overcharge my bank of bateries 20 bateries

Please tell us again, the part # of your batteries, as something is very wrong, an you are describing an impossible system

Please tell us what components you HAVE. Don't buy anything else yet
