I have 24v system. . Controller recognizes panel and displays battery voltage. LED says Solar OFF. I am unable to turn solar to ON to charge batt

I am not real knoledgable on it and the only thing is to make sure the wires off the panel are correct posative and negative and as I am thinking try putting a meter on it to see if panels are puting out power then check conrctions doen to the battery to see where the problem might be. Hopefully this is some help.

What exactly are you asking? We hooked them up by the instructions. You need to buy the controller separately. They seem to be working properly. They have a red light that is on all the time so the solar is working. If the battery is totally dead it will not charge. If the battery is good it will keep it good and charged. Any other questions please ask.

If you are using 4 panels with this kit it only uses a 20 amp controller. You must be using a 24v battery bank to use up to 400 watts. Can you explain your situation a little more? We are a bit confused with what setup you have. Thank you. AW

A test you can make is to directly connect the panel to the battery, correct polarity important or you will fry things. If the voltage is 17 volts or under you are good to go. If it is still over 18 volts you will be over current and ruin the battery. You cannot have the controller set to 24 volts for your 12volt battery!

for these panels since they are 24v panels you would need an MPPT charge controller. You would also need an adapter kit to connect your panels to your charge controller an a tray cable to connect the controller to your battery bank. And since these are 24v panels you would need a 24v battery bank.

Check your battery set up correct and make sure your charge controller is a MPPT

Val this charge controller can only handle a maximum of 500w of solar for a 12v battery system, or up to 1000w for a 24v battery system. Since you are planning to use 3 x 250w, you will need to wire those batteries in series for 24v, and get a 24v inverter. If you don't want to go for a 24v battery configuration, and want to stick with 12v, then you will need to drop a panel and just go with 500w, or you will need to use an additional controller (controller 1: 2x250w, controller 2: 1x250w or 2x250w).

I purchased this after reading the other responses and can confirm. I'm using a single Solarworld 250w panel (24v) with two 6v Sun eXtender batteries (wired for 12v). Works great.

Of course friend, the panel is high efficiency, full sun generates 22 volts, you need a charge controller 12 Volt so you do not overload the system, it will keep you charged and when the battery is charged, disconnect, which prevents damage to your batteries!

Did you verify the correct terminals for battery and solar panel were corect?Sounds like charge controller might be bad.You could bypass the charge controller and connect the panel to the battery. Just remember as it can severally overcharge and damage battery.This would confirm operation of the panel and battery. Charge controllers are cheep to replace and can be purchased seperatly.

Hello,If you are charging 12v nominal battery bank you can input up to 400 watts of solar power.If you are charging 24v nominal battery bank you can input up to 800 watts of solar power.The wiring configuration of the 800 watt panel setup must be done so that you do not parallel all of them or not series all of them or else the panels will either go out of the 100 VDC or the 40A rating.The 800 watt setup must be wiring in series/parallel.Please let us now if you have any further questions.Regards,AW

The charge controller is for regulating the battery charging. Step down the higher solar panel voltages to 12volts(around). It can also prevent the battery from back charging the solar panels in the night.

Be sure you put a 'charge controller' (regulator) between the panel and the battery. If you don't, you will overcharge the battery daytime, and fry the panel at night (because the battery will back up into the panel and fry it).

Because the voltage is 40 volts, you need to buy a voltage controller that accepts input for 24 volt or 12 volt. and the output for the battery will be 24 or 12 volt. The voltage controller will automatically detect the input voltage of the solar panel and will automatically detect the battery voltage. I have purchased two of these items on amazon. However, One seller was in Shanghai and the other in Hong Kong. you can get 30 watt or 60 watt. Blue Solar was the name of one of them. I did get both delivered after a while.

yes the voltage output will vary with the amount of sunlight. I have my panels setup to produce a max of 36 vdc charging a 12 vdc battery bank. your charge controller needs to match your projected final system capacity, if there is a possibility of adding on later. I have a mix of 144s and 88s

I connect to 24v batteries rather than solar panels to get max 300w out. The batteries are solar charged.

Get an externle battry from EasyACC male sure its tells you it is for your device the battery in your device is a little to big for the smaller 3v off the panels its what I had to do brighT side is now I have a back up win the power is down for a while I hope this helps
