Error codes EE8 & EE1 ???I killed 2, using them on a small 30x30cm (12x12in) solar panel I use to trickle charge my car battery. Voc < 30V

I too have had 2 units give me these error messages, EE8, EE1, and EE2. They work one day and go into error state for no reason the next day. Vendor has no idea how to fix the error and XRITE would not replace any of the units. Would like to know if there is a reset to clear the error.

You'll melt it down if you hook it up in line you can only check a battery ..you cannot check running voltage

Need clarification. Are the error codes displayed when connected to the solar panel or lipo batteries after having used on solar panels? Not sure but these are made to check voltages on cells of a battery. The batteries it's designed for are 3.7v on each typically charged to 4.6 or so. If the volage exceeded that it may have damaged the circuitry. Either way they are so cheap I would just get new ones.

How did you try to measure 24 volts? If you used 2 twelve volt batteries in series make sure they were connected one + lead to the other - lead. Or try to measure 3 nine volt batteries snapped together. You should get 27 volts. I think there is a calibration pot on the back of the meter. It is very small and you will need a jewelers screwdriver to adjust it. Make sure the red lead goes to the + termingal of the battery. Try again and let me know. You could have a bad batch of meters. Mine worked very will on my power supply that goes up to 27 volts. One last thing...are the 24 volt batteries you are measuring good batteries? The meter might be telling you that they are not. Hope this was useful. Also be aware that all meters have a percentage of error. Some are + - .1% + - .01%. No matter how expensive the meter it will have error tho very small. The smaller the error, the larger the price. These cheap but beautiful meters are good enough for battery monitoring. I wouldnt use them to build a computer power supply.

When I first saw this product had a cut out voltage of 14.2 i thought 'hey that's low...' in my humble opinion(the only meaning of IMHO i know) you should look into the difference between charge types, float, bulk... then you will understand the numbers on this unit, and your batteries a bit better.

MY answer was AA, They are not AA just similar in size AA would be 1.5 volts@. These are a little larger and are 3.7 volts @. Sorry for the confusion, Hope this clarifies the issue.

I am using this with a Grape 250 W 30.7 V solar panel with no problem. On clear days it is not unusual to get over 33 V. This has no problems with it. I'm certain I could put another in line and still be fine.

The voltage specs mention 3.6 V. If the AA battery used has a voltage different from 1.2V, it could create such a problem. Many AA batteries give out 1.5V, which means 4.5V on a 3 pack - which is a load on the system and can perhaps fry up some circuits causing the sensor to malfunction.

Hello, The E-1 Code means that the element inside of your unit is burned out. I had a lot of trouble with mine when i bought it. There were loose wires inside the unit and mine didnt work at all. I bought two of these infrared heaters to reduce my electrical bill but they actually increased my electric bill because they ran constantly. I no longer use them at all and i am saving my heaters for emergency back up only. They do not reduce your electric bill like the product indicates and i thought they would reduce my bill by 25% but that is false advertising by the manufacturer. I hope this helps you out!

You would be looking at around 37V to charge a 24V battery bank at minimum. You can get 3 of these 37V panels and wire these in series and pump 111V under load into the battery bank with this controller. As long as the Voc voltage doesnt exceed 150V. The Voc voltage for these 37V panels is around 45V. You will get the 37V once its connected to the controller and in use but the panels will 45V just sitting there and measured with a voltmeter.

Not a good idea to draw volts off one or two batteries. Use a voltage reducer.

ALSO, if you use rechargeable AA's, which are 1.2v instead of 1.5v, you get 9.6v out of 8 AA's. Ingenious way to potentially utilize rechargeable AA's in a 9V device!

This is also a fail safe if you have too many volts going to the unit. Are you using a stock adapter or a different one you purchased?

I bought 3 in 2011. I don't recall any instructions. It is designed to charge a 12 volt or lower system. Care must be taken not to over charge the battery. I hooked them up to my car battery for a trickle charge. There is a diode in the black box on the back so at night it will not discharge the battery. Make sure it is hooked up right. check the voltage in sunlight to be sure which is positive and negative. Hook up solar panel positive to battery positive etc.

Don't do it! The excess voltage would surely burn something out. (If they even fit.) There are numerous suitable "double A" batteries that will work, including many rechargeable ones.

i'm using mine on standard wire size that is on the solar panels.,not sure what that actual size is.,if you need it i will check the wire tomorrow.

I really wish someone would have done the math on this already. The pack holds 8 batteries. If you use alkaline batteries, which are 1.5v each, you get 8x1.5=12 volts. If you use nimh rechargeable batteries, which are 1.2v, you get 8x1.2=9.6v.The reason it shows 12v is because 8 normal AA batteries will yield 12v. The pumps can handle 12v just fine. We personally use rechargeables- we bought 16 rechargeable eneloops and just swap them every 3 days or so (my wife pumps exclusively). We found that we can stretch it to four days but beyond that the pump will start to die.

If you plugged the voltage adapter into the wrong voltage, you could have burnt a circuit. Voltage must be compatible.

I'm not sure of the difference, but whatever you do, make sure that all the#'s match up don't mix of they don't! Example the EN-EL14 is 7.4V 1030mAh 7.7Wh, if those don't match, don't mix. But on the plus side, it will still work with 1 battery at a time, so just keep them charged up and ready to shoot!
