Batter over-discharged, what does this mean?

[cyras21]

If the picture (and hopefully more detailed wiring diagram) shows the two batteries in series (+ of one connected to - of the other and the two remaining terminals connected to the gate wiring) then two 12 volt batteries will produce a total of 24 volts, and you MUST use two, and you need at least two solar panels or one panel that has a 36 volt output.

If the picture shows the two batteries in parallel (+ to + and - to -) then you will be getting 12 volts but with more current available for the motor. In that case you might get by with just one battery, but it will not last as long or open the gate as many times without recharging. Then you just have the wrong model charger.

I guess some guys (me) will never learn to read the directions first. The diagram does show 2 batteries producing 24V. Will one more solar panel like the one I have be enough? Does the wattage of the panel have anything to do with the wattage of the motor? Thanks for y'all's help.

Thanks guys, I'll see what the motor requires and updraft my power.

You need to start at the beginning and determine what voltage and battery size will run that gate. Then get a charger to match up to the battery voltage. And finally size your solar panel so you have enough wattage to charge your battery.

I see a few things that may be your problem.

First as Sunking stated you have a 24 volt charger and a 12 volt battery which won't work together.

Second as inetdog states your 20 watt 12 volt solar panel does not match up to your 24 volt charger.

Next possible issue is with the Humminbird battery. I can't find exactly how many Amp Hours it is rated but it may be too small to run your motorized gate.

Well let's se if we have a clue or not. You have a 12 volt battery and a 24 volt controller.

What is wrong with this picture?

Yes, but the manufacturer says to use a 12v battery. They did have 2 pictured but I didn't think it would matter.

Don't forget the nominal 12 volt panel either!

Hello,

I've recently installed a motorized gate and am using a solar panel and battery to power it. The controller has two leds one which means batter over-discharged. Any idea what this means? When I bought the battery I charged it with the accompanying charger. It sat for about 2 weeks before I connected it to the solar panel.

The panel I'm using is
12V/20W Solar Panel
Rated Max Power: 20 Watts
Current at Power Max: 0.57 Amps
Open Current Voltage: 21.5 Volts

The controller is
ALEKO® LM118 24-Volt Charge Controller for Solar Panel

The batter is
Humminbird 7700281 GCBK CSB GP1272 Portable AGM Battery
