Planning for solar power system. Can this be connected even when batteries are charged by the solar panels? Or should it be disconnected when not reqd

I would not, its designed to have electricity running through it all the time. The battery tender turns on when the battery needs juice. A solar panel is not constantly pulling energy, and this is always turned on. I would ask someone who is an automotive electrician.

It can be hooked up if you have grid power other then the panels themselves. It will defeat the purpose if you are plugging it into your power inverter because that is pulling power from your batteries where the Battery Tender is trying to put a trickle charge back into them.

Not sure, I would contact Battery Tender Company,I'm sure they could advise you.

My battery tender stays connected all the time. It only comes on when the battery needs charging. It has a red and a green light to tell you what mode it is in. Solar energy used for charging should not make a difference.

I do not know I just use it with batteries and the solar system charge the batteries.

Just started mine. The load goes to the equipment you are powering, the battery goes to the battery as indicated. This unit is to automatically control the charging of the batteries only when needed and take power from either the solar cell or battery when the load is on. I can give more in a couple weeks after mine has been fully tested. If you hook the batteries to the load terminal it can overcharge the batteries and cause problems, maybe even fire. Not knowing how you are using this it is the best I can answer. Correct connections will be important if the load is not constant.

I do not believe that this is possible, though I could be wrong. I was under the impression that this requires a bit of skill, perhaps a designated solar breaker, etc. The battery required, would be a solar battery (deep cycle battery). You would wire this from the panels to a solar charge controller, battery and an inverter.

It needs to be always connected. It runs on USB so you might be able to use one of those backup batteries with it

battery is connected the solar power also connected to normal position for charge , but at least 1 week some time 5 day the control is hang even touch any key display not change , but after disconnect battery and connect again display active it's stating to working normal.When automatic shutdown we need to restart ? or start up automatically ?

The short answer is, "Yes." You could connect the output of the solar panel to a 12 volt battery bank. The battery bank will recharge. HOWEVER, if you don't either monitor or regulate this, you will damage the battery bank from overcharging it. Specifically, if you could manually check on the voltage very couple hours, you could disconnect the solar panel when the voltage reaches full charge. or you could get a charge controller that is wired in between the solar panel and the battery bank. This inexpensive device will both optimize the charging current to the battery and will stop the charging when the battery is full. The short answer is, "Yes."

You should NOT connect directly to a solar panel.... you should go thru a charge controller to regulate voltage, and to cut it off when solar panels do not generate enough current/voltage...

That's a good question. I THINK it works by either charging the connected device from its battery, or by charging the battery. There's an on/off switch that powers the USB connection. So that's a way to differentiate this from a true solar charger. With this you can charge and store, with a solar charger you have to leave the device connected to the solar charger and in the sun to charge. I could be wrong about that. I may ahve to test that the next sunny day.

Yes, It need grid potential to operate. During utility power outages you solar system is nonoperational.

Yes it could stay connected long term without harm. As for starting I would have unplug just in case the amp draw is to high but this is pretty cheap cost wise so worth a shot. Don't forget your solar panel 40w at least.

I dont know. I have only used mine once when the electicity was out. I haven't even tried charging mine with the solar panel. I keep it plugged in.

Hi, Yes, you can keep this system connected to the solar panels or you can purchase a wall ac charger that you can plug into a wall ac outlet to keep the system charged. We offer the wall chargers on our website. Thanks

you should not connect these panels directly to your batter bank. they should be connected to a charge controller and from the charge controller you connect the battery bank. depending on the charge controller you would then either connect your inverter to the battery bank or as on my controller there is a lead that can connect directly to a load such as an inverter.....hope this helps. I'd recommend researching charge controllers so that you keep your batteries in the best condition possible. I bought my controller from http://www.windsun.com/

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!

Without seeing the schematic for the hook up, it is hard to advise you. There should be a charge input, that would go to the solar panel. There should be a load, that should be the device you are running, and there should be a battery connection, which is of course the battery. Make sure you observe the correct polarities on all of them. They should me marked + and -. If you are not sure, use a volt-ohm-meter to check.
