if the battery is over discharged (which happens occasionally in the winter time when there isn’t enough solar power to keep up with the power draw from the electronics this solar setup is running), how do I get the battery to start charging again WITHOUT putting it on a battery charger? It seems as though the solar controller won’t work if the battery is over discharged. My application is a remote installation, so putting the battery on a charger is not possible….. Pls help!

The answer is simple......
You need a larger system.......... More batteries and more panels, Or use less power.........
Hope this answers your question......

The solution that tattoo mentions is perfect. The main drawback is that, depending on the circumstances, you might not be able to afford the over capacity. This is analogous to the problem that banks and other service providers face. In order to keep customers from waiting in line, you have to have enough tellers to service maximum demand, but then they sit idle most of the time. In your case, if you can't afford to buy and install enough batteries and panels to keep the batteries healthy under maximum load, even when you get no sun for (days?), then you need to install a battery protection circuit. These devices prevent the battery voltage from falling below a level equivalent to 40% DOD (open circuit). Setting the device is tricky because it will be under load during testing. And if the load is way bigger than you have capacity for, the system will oscillate - going on and off every few seconds as the protection circuit is tripped by the rapid dips and rebounds of an an over stressed battery. So, you might want to consider a combination approach: (1) Try to enhance your system, per tattoo to keep your batteries at 40% DOD most of the time in your most typical weather. (2) Then also install a battery protection circuit and perhaps even a day / night timer, to keep the batteries from draining into damaging territory at night, or when you don't get enough sun. Here is an example of the circuits I am talking about (I actually use cheaper ones): Low Voltage Disconnect |

I was trying to answer his question the simplest I could so he could understand why he is having an over discharge problem........
Money is always a problem that's why I didn't address it.......
You know dogg, I try and look at things as simple as possible...... The way I look at it, the batteries, CC and everything else in the system has no idea how much money someone has, All the CC knows is there is more power going out than coming in and it can't work with those parameters......
The way I look at it, it's a VERY easy fix and there is no need to spend any money at all, No need for a low voltage disconnect....... just STOP using more power than your making each day......... That's free...........
Problem solved............
Is that better? ? ? ? ? ? I guess it wasn't any better........ Sorry it bothered you that wasn't my intention......

These comments are meant to be for the benefit of the original poster. I have no interest in starting or continuing any kind of confrontation with any other user.
Low Voltage Disconnect serves the purpose of protecting a battery from being over discharged, regardless of the reason. Whether it be an accident or system design. Your ego will be hurt a lot less than your pocketbook if for whatever reason, your expensive battery is ruined.
A high quality LVD, such as the Blue Sea can be had for under $70. Cheap insurance. Like all insurance, the best way to prove that you don't need it, is to not have an accident, or not to die.
Here is another discussion. There is lots info out there. Read up an make your own decision.

Where did you see that I was starting something with you..............
I was trying to explain it in a simple way.......
Now why are you yelling? ? ? ?

Going by what you said, What if he doesn't have $70.00? |

I believe the over discharge limit is set to 11v and may be programmable below that, that is the minimum voltage for the controller to work so if you system goes below that and a battery charger is not available then try an alternator (jumper cables) from what ever vehicle you visit this remote site. If the load is within the limit of the controller's load terminals that may be a possibility since I believe its low voltage disconnect is higher than the minimum voltage to keep the controller operating.

Not yelling. I have problems with my eyes sometimes and I made the font bigger to cut down on my typing mistakes, then I forgot to scale back down before posting. |
