Will I be able to use this product to operate sump pumps off the home circuit and then auto switch to a battery bank in case of power failure?

This switch transfers from 120 volts to an auxiliary 120 volt source such as from your home power to a generator. It will not operate off battery power.

Yes, so long as the power options for it to choose between are both 120V 60 Hz AC and the load is less than 30 Amps. So those batts better feed through an inverter.

I think it would work just fine for the amount of power it would draw. Although you stated that it is a 12 volt system so you could run it directly from a battery unless you wanted to use an AC to Dc adapter.

I think you could make it work, but you would have to be very careful setting the float switch to de-energize your pump. This setup is not really very accurate for repeatability.

No it won't work. The pump does not work in your situation. It's lack of an on off switch, instead it uses the pressure of a water tank to turn on and off the pump.

If it were just a sump pump I would say yes, but being a battery backup where everything is tied together I would say no? Not for sure though. The float on this is not the large ones that come with most sump pumps. There are two small floats that do not need to have that much water to rise them to set the pump off. For just regular sump pumps you have to google: PumpBiz. They are in Chicago and I have ordered all my pumps from them. Ask for Jeff Richmond. They have sold me countless 'switches' that act as a float but it uses a wire that when the water hits the wire it sets off a manual pump. You have to get this.

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.

Previous comment is right on -- this is for dedicated pump on/off switching.

That would depend on the amperage of your sump pump and the length of your extension cord... By doing a little research online, I would say that if your sump is 6 amps or below and you limit the length of your extension to 50 ft or 75 ft at the longest you should do okay. This is just my opinion as I have not run a motor with an extension on my own unit. I have had my unit for a year and love it. We use it to charge phones, computers, lights, Ipods, etc... when camping. We keep it busy and use it a lot. We have done away with D batteries for flashlights and fans. :D

Danny F. pretty well nailed it. You must know the approximate power drain of the sump pump to determine how long the device can be powered. How many different sump pumps are out there with various capabilities?? The suggestion to supplement with a car battery is most useful.

I don't see why not but this might be overkill for that. As for the connection, I believe the site where this is listed contains several plans depending on what you are trying to do. You can run this from a 9 volt battery so power should not be a problem.

As long as your input into the pump is 12v DC you should be fine. That is my educated guess.

I believe if you were to use this timer for that purpose that a properly sized relay should be used to switch the load and the timer would turn the relay on and off. Pumps draw a large current especially during startup. For durability the relay should be about 30amp.

As long as the main battery line that you are talking about is large enough to carry the additional combined total load for 3-4 of them, it should be no problem. The rated input for each one is 3 amps.

I can't say for sure whether it will work or not, but I wouldn't recommend using it for that. If one of your batteries goes bad it could drain all four connected batteries, and ruin them as well.

I would think so. I am using mine for a 1.5HP pump to power a water feature. One word of caution- this timer should be mounted high enough to allow your plug from the pump to be plugged into the bottom of the timer.

Potentially, if the voltage and amperage are correctly matched. I would suggest purchasing a wall plug w/ the correct adaptor for your unit though. I use this b/c my portable pump has a direct power cord from the unit and no adaptor.

No, but as long as the pump is DC powered and it is no more than 0-24 volts (max rated controller voltage) you should be good
