can i used these with battery bank to power my home well water pump, during extended blackouts?

You can use these to power well pump etc but you really will need a good battery bank with good quality batteries and the most important part of your system will be the power inverter. You will have to get a good quality pure sign-wave inverter to use for house hold appliances and water pump. The panels are excellent and the price is good but everything else that you need to add gets a lot more expensive. Batteries are around 200 each, inverter is around 1000+ etc.Hope this helps a bit, you can research off the grid hunt camp power systems to find out more information.

Yes. You connect the battery with the charge controller. This is only for 12Volt battery. If you have 24volts, you will need to replace the charge controller with a MPPT one.

Yes if you wire them correctly u can do that. There are different ways to connect the batteries. But are you using 24v. Most low voltage is 12v. Im no expert or electrician. Just based on experience

I am not an expert here but I would not do that. What I would do is have two different battery banks with a photo sensitive switch that connects the two banks at night. That means, during the day, the banks would be separate but when the sun goes down, the switch would turn on and connect the two battery banks. I have never heard of anyone doing my idea but I think it would work. You are getting advice from an non-pro here so do not act on anything I say without talking to a pro first.

They draw very little current, in the milliamps. You can probably leave them on for a while, as to how long would be an interesting test. Like anything, eventually it will drain you battery, even if you are drawing milliamps. Several hours would probably be ok, I would not leave it overnight.

Yes, particularly low self-discharge AA's like Sanyo Eneloops. For a compact emergency multi-day outage situation, consider adding a Powerfilm AA (4 AA version) folding solar panel to charge those batteries.

No, and yes. They are hooked up to the battery, and then a charger constantly charges the batteries. So it will work if the power is on and your other pump dies. It just operates by a float switch that you place higher than the main pump float switch. It doesn't run directly off of AC power but if it is getting used and the power is on, the battery will be getting replenished. If you had a real heavy flow for a long time then I'm not sure the charger would keep up and the battery might exhaust. But yes, it can act as a sort of failsafe if the main pump seizes and the power is still on. It doesn't require that the power is off in order to work. No, and yes.

I think so, for how long I couldn't say. I used a 6volt lantern battery and ran it for an hour or two in an experiment to use it as the circulation pump for a solar water heater I'm building. That battery is still strong. The flow was actually a little too fast for what I was trying to do. It's a good little pump, i think.

I connected mine to a 12Vdc power supply that I had from a previous project. batteries should work too, but of course they would require re-charging, kind of a pain. I installed a switch to turn the pump on and off. Also, I plan to use mine for sparging a beer mash. The pump has some gears that are lubricated with some type of grease. I would recommend running some hot water through it several times, before using it for human consumption. but it seems to run well, just a little noisy. hope this helps,

My guess is that you will be fine. I run these directly off a battery bank that gets almost to 14V. I have two problems that will cause me not to buy more for use in the Amazon (the REAL Amazon, not the retailer): 1) they are too wide to be used in pull-chain sockets (the cord doesn't pull freely), 2) again, an Amazon thing, they fill up with insects due to the design of the diffuser. Luckily, it's easily pupped off and cleaned.

I think it would work for a much longer outage than that. I'm not sure what your pump is rated in gpm vs. basepump gpm, but as long as they're close, you should be fine.

Really depends on the intended use. I use these for inverter/grid power switching. It allows me to separate the grid bank to two banks one of which would only have the needed inverter loads.

Yes. I purchased it to replace the same battery that was in my home alarm unit. It serves as a back-up power supply in case of a power outage. It works dependably when the electricity fails (that doesn't happen here too often).

Hi Cynthia, A battery pack can be used. If the electric is out for less than an hour, it probably won't matter. DON'T open the lid during that time... What you want to search is "uninterruptible power supply," or UPS

yes I used it during a blackout for a few nights with the battery of my cordless drill it didn't last for more than 6-7 hours per charge witch i did by day by a friend who had a generator and it got us thru from it got dark till we went to sleep

Depends on the starting amperage draw of the pump and the length of the cords. There will be a loss of power proportionate to the length of the cords. Better check with a pro electrician.

I would think so, but I wouldn't know since I havent used them yet. I got them as a back up. since eventually battery packs go out I figured I would only use them if an emergency occurred. Put them with bug out stuff (Hahahah i a prepper), figured If I get 6 months to a year of light with sun power in a OMG situation, the 12 bucks was worth it :) I should crack one open to see serial number or pack to see if they are available for back ups......hahaha back ups for my back ups couldnt hurt!

I would say no. You'd need a battery bank of about 6 12 volt re batteries ... and at such a drain from the freezer I am thinking it would take about 120 watts per hour of solar panels to keep the bank charged overnight. You'd want a much stronger inverter and controller than what comes with this kit.
