PumpSpy 1500W Sump Pump Battery Backup System, Safe Back Up System for Emergency and Power Outage, Superior Home Silent Sump Pump Backup Power Supply with Intelligent Cooling

I’m very pleased with both the pump spy back up/inverter unit and the pump by deep cycle 12 V battery. Installation was a breeze and my system was up and running in no time. Slightly disappointed that the RJ-45 port was not used. I was hoping to interface that with my network. But all in all these two pumps by products seem to be top-of-the-line and I look forward to them lasting for a long, long time.

I'm only a day into this but so far so good. I paired it with a fairly inexpensive group 27DC marine battery. I let the internal charger top it off. During the charge it regulated the voltage to 14.4 volts. Once charged the green light came on and the voltage settled in at 13.8 volts and stayed there. Just what a good charger should do. I have not measured the total charge and discharge currents as I'm waiting for a meter shunt to arrive so I can. This morning I unplugged the mains and the PumpSpy inverter maintained power to the pump. My pump currently cycles every4-5 minutes for about a 10 second duration. In the first 4 hours the voltage stayed above 13 volts. After running 15 hours the voltage is hanging around 12.4 volts dipping to 12.1 volts when the pump is on. I'm sure I have several hours available but I'm going to plug it back in to avoid shortening battery life. I'm debating a second battery to double that run time but so this has far exceeded my expectations. Kudos to the company for being really responsive in answering questions. I'll followup after further testing and experience. UPDATE: I added a second battery in parallel (after equalizing) and was able to go at least 48 hours. The voltage never dipped below 12.1 volts. I'm sure I could probably get another 24 hours easily since the inverter doesn't alarm until it gets down to 10.8 volts. Rather than stressing the battery bank further I concluded the test after 48 hours. Very pleased and is working much better than I expected. It's great to have the peace of mind that the sump will continue to run even during extended power outages.

Worked as advertised for my 1/3 hp Sump pump. Much quieter than the old storm pro 35acv inverter that crapped out. Easy install despite Ridiculously short red/black battery cables. I either have to a) drill another hole in my battery box; b) keep lid partially opened so cables can reach or c) buy longer cables

The PumpSpy 2000 power inverter was easy to set up & is working fantastic.

This PUMP SPY 1500W inverter works flawlessly. It powers my 11.5 Amp sewage pump with no issues. I highly recommend it for peace of mind . Some complain of the fans being loud . They sure don’t bother me at all . Especially knowing my basement is protected. I actually think they sound cool !

UPDATED 22July2023: After returning the defective unit and receiving a credit, I ordered a 2nd unit. It arrived undamaged and I installed it with no issues. And only a couple of weeks later, I had a 6hr power outage during heavy rain and the unit did indeed keep the pump running.HOWEVER...I just today identified another SERIOUS defect - the unit emits severe RFI. I am an Amateur Radio operator and noticed new interference on the Amateur HF bands, particularly strong between 9-11MHz. It is so bad that it renders a large portion of the HF band unusable for me, and likely is causing RFI issues with my neighbors too. I will be contacting the manufacturer as RFI of this magnitude is a violation of FCC regulations.Very disappointed in the build quality of something this expensive and made in the USA. There were three major defects:1. The B+ battery terminal insulator was shattered. Half of it was missing, bits were in the box. Don't believe this was shipping damage because these posts are well protected by foam and the box was not damaged at all.2. One of the screws on the side is only half installed, and whatever it is holding on the inside is loose.3. There is something loose and rattling around inside the unit. You can hear it when you tilt it back and forth.No way was I gonna trust this thing to be plugged into my house wiring and sump pump. And of course I bought the expensive battery, so now I have to buy another one after I return the defect and hope it is built correctly.

This isn’t the cheapest battery sump backup controller you can find but it is much higher quality than others I researched. It was easy to set up and it’s clear how much battery health you have by looking at the monitor on the side of the unit. If I need this to work when the power goes out, I’m confident that it will perform based on my testing of it thus far.

The media could not be loaded. Mounting to concrete was impossible using a normal hand drill. After going through 3 masonry drill bits and more than an hour, I rented a Hammer Drill. Other than the inconvenience & cost, that did the job. Four holes, 2” deep was done in about 5 minutes. Six or seven inches longer battery wires would have helped. My reason for the 4 rating is I’ve only had it installed for a week.Why can’t I get an answer to questions about the RJ-45 port?

Looked at various options for providing backup power to my sump pump at times of power failures, which is not uncommon in my neck of the woods. Installation was straightforward. Just follow the instructions and you will be fine. With my current setup, and sump pump cycling frequency, i estimate that my 100Ah battery will provide about 5 hours of protection. I also plan on connecting my freezer onto the second outlet, which is within the 16.6 amps 2000 watt specifications. Note that you can extend the power backup time by adding more batteries in parallel. My tests were all perfect and quite satisfactory.

Easy to install. You have to buy the batteries, Haven't needed it yet,but have faith when hydro goes out, it will work.

This unit does not work on its own. You have to connect it to a car battery. I did not know that until I read the manual. Why is this critical piece of information not given in the description? To me, it is just hiding the information from buyers. I paid about C$900 for this charger, and now I have to buy a battery for it.In addition to that, the manual is tiny and hard to read. My question to the seller that: is it too expensive to print something that your buyers can read? I am disgusted by the cheapness of the seller/manufacturer.

First time I'm ever writing a bad review but I just don't want someone else falls for this.Product is coming from US.After setting it up, the product is defective (One outlet is always on and the battery is draining).Couldn't return it as the item wasn't clearing the customs. Seller wasn't helpful about it and now I'm stuck with a thousand dollar battery draining system.I don't recommend it.
