Does this automatically stop the batteries from back-feeding into the solar panels at night?

Yes it does. It also stops putting power in the batteries when it reaches around 14.2 volts. On a nice sunny day I run my large freezer on solar power to save a little. Nice what you can do with the sun.

Correct. They come on automatically at dark. You can shut them off with a switch on the back and keep the battery charged.

The unit will stay on for a short period of time after fully charge, but should go off completely till darkness arrives.make sure the solar panel is not in the shade or a shadow that make it come on thinking it in the dark of night. If this keep doing that, try to reset it again, turn it off and on again and this should do the job. If it keep acting up, it might be defected.

You usually have to have some type of controller to prevent battery overcharging. I hooked my solar charger to a gate opener that has a built in controller for the battery.

No..once you put the cover down, it automatically turn the switch to off....i think for safety purposes not to drain your battery or any power....hope this will help!

No. Under the lid is a small plastic tab you have to pull out. Once you do that the sun will charge the battery and you will be ready to go. It turns on when it gets dark...but as I said you must pull out that tab. Hope this helps. If not write me back. Good luck and enjoy your lights.

What would work best, and what we do, is turn sensitivity dial to 1 during the day. This enables the solar charging, but the unit isn't likely to spray. At night turn dial to it's operational setting. If the unit is turned off during the day it won't charge. There isn't a timer that would automatically perform this, but we don't find it a problem.

Yes. I disconnect the battery from my camper 'load' during the day, allowing the battery to charge, then switch back to battery in the evening. Just requires in-line switch for 'load' side of controller to camper and in-line switch from battery to camper. Has been working quite well.

no it shuts off automatically once the battery is chargedI use this on my wholehouse diesel generator

You can just hook it up +&-. Or you can get a charge controller that will desulfinate the battery, not overcharge and not discharge at night. There is lots of 'em available... Me, I like the Battery Tender 021-1162 Solar Panel Charger Controller

Yes, its exactly what its ment for. Turns off automaticlly when battery has a full charge. great product.

No, the way I understand it... it won't cook the battery or drain it during the night. I've left one on for several months at a time.

Yes, just connect it independently to the batteries(not through the solar charge controller).

As far as I know, no it doesn't. Simple on/off switch turns on light. I suppose you could keep it "on" all the time and let it run out of juice, which would be replenished the next day when the sun is out?

Yes, this is intended to remain connected to a battery 24/7 (whether in a car or out of a car) and it begins charging the battery when solar power is available and the battery voltage is 13V or less, then once the battery voltage is raised to 14V (showing it is charged) it will stop the charging. If you will be connecting a solar panel thru a lighter plug in a car (which seems to be the easiest place), I hope the lighter remains "on" without the keys in the ignition (otherwise your "charge" power will not be getting thru to the battery making putting all of this together pointless). If you were to start a car with the panels connected up, the panels may send their rated power to help start the car (during good daylight), but they won't put out any "extra" power (they are not a battery that "store up" power or such, they just give you what they can). Once the car is started, the car alternator should instantly recharge the batteries and the green light on this should instantly come on (showing that solar power is blocked).

You will still need a diode on your panel to prevent the battery from discharging overnight.

Out of habit, I turn off the power. I have not tried to determine if it has an automatic time-out feature. I suspect that it doesn't.
