2000W Primary Sump Pump Backup System, Basment Protection Sump Pump Inverter, Black, LCD Display, Auto Switches for Continuous Sump Pump Operation, Basement Emergency and Power Outage Backup

I cannot get water in my basement without ruining a lot of my stuff, so I bought a Zoeller sump pump, this inverter and a Delco AGM battery. I was able to put it all together and replace my old unit that came with my new house in about 30 minutes. Was really quite easy and I was surprised. My plumber wanted $500 to install a sump pump which is a 15 minute job. The money I saved I installing it myself paid for the backup system. It connected up easily and worked perfectly. Tested it by u plugging from the wall outlet and the battery backup worked like a charm. I feel my safer now and have peace of mind. I would recommend doing what I did. This inverter looks to be excellent quality, has a nice LCD lighted information display on front and installs easily. Recommended!

I bought this to have a backup for my basement sump pump when the power goes out for a coastal Maine home. The power frequently goes out for days at our second home during storms and we had an issue that the basement would flood because the sump pump had no power. I purchased a decent deep cycle battery at Walmart to pair with this and set up was a breeze. I tested the unit and it switched from AC to DC and back to AC by plugging in, unplugging, and plugging back in the sump power cord which connects directly to the unit. It worked well and the unit recharges the battery on a trickle after it switches back to AC. Worked great in a power outage shortly after I installed it. Highly recommend this for a similar set up.

My unit is the 1500w model. The inverter is easy to install. I tested the unit with 120VAC being supplied and with AC off (unplugged). It worked fine. Switchover from AC to battery backup was extremely quick.Now the issues. As others have stated, the owner's manual is useless. I have never seen a worse manual in all my days. Luckily, the inverter hookup is not that complicated. However, I did have an issue when I inserted a tester into the inverter's 120VAC output. It indicated a ground fault. After some time of checking things out, I noticed a small terminal with a ground symbol beneath it. Connecting the terminal to ground solved that issue. But once again, the manual never mentions this connection. The last thing is two plastic covers are provided for the battery connection lugs. But I cannot figure out have to install them. They would protect the battery terminals from accidental touching, if only I could figure out how to install them.

I had my first power outage since I bought it the other day (6 months after I bought it). It only works when power is supplied to it, which defeats the purpose of having it. Amazon won't refund me, and there doesn't seem to be a way to find the company. It came with a manual that says there is a one year warranty... Not very useful if you can't find the company.

This backup is great. The build is good quality and it was easy to install. Instructions could be a little better for the cable connection but it works fine. No noise at all and powered up as soon as it was connected to the power and batteries. Tested everything by unplugging from the wall and it works as it should. I did end up returning the 2000 one for a larger wattage only for the fact that I didn’t see that one before hand. Otherwise both of them (from this company) we’re the same and worked perfectly.

Just hooked it, so far so good. Did a test run and it worked just fine. set up was a cinch

Purchased this for sump pump and it’s working as expected. Easy to hookup even with the instructions being terrible.

Without a doubt the absolute worst owners manual!!! The instructions for installing are not there, not written, not included!!!! Good thing I have a good puzzle skills!!!! And no where in the manual did it say what battery to use. Otherwise it seems sturdy, it’s all hooked up, tested and saying a prayer that it works!!!

Just tested and work great

Pour une pompe à puisard ( back up ) en cas de pannes de courant , je l’ai tester fonctionne très bien , la seule critique les fil sont un peut cours , j’en ait fait venir un set de 24 pouces , il devrait avoir des fil plus long 18 ou 24 pouces ,

This unit was defective, did not operate as described. Ups clearly did not work unit only discharges battery not keep charged as advertised

EVERYTHING SEEN TO BE FINE. WILL SEE AFTER A YEAR.

J'ai commandé 2 appareils en même temps. L'un des deux est reçu endommagé. L'isolateur rouge de la borne de batterie est fendu. L'emballage est intacte. L'appareil fonctionne quand même mais il fait un 'clik-clik-clik...' électronique interne continuel. Je le retourne car j'ai payé pour 2 appareils fonctionnel et neuf.
