Customer Reviews for VEVOR 2000W Sump Pump Battery Backup with LCD, Automatically Shifts to Inverter Power Ensuring Uninterrupted Operation, Essential for Emergencies & Power Failures

Très bon produit Il est installé depuis quelques mois avec un batterie Fonctionne très bien avec la pompe lors de panne électrique

Finally put this to the test with a storm that knocked power out for a week. This coupled with a 12V marine battery kept my basement dry for days. After around 48 hours of intermittent pumping, the inverter started giving a low voltage warning. After plugging it into a borrowed generator, I was able to recharge the battery in a few hours and was good for several more days. This can also be used to charge devices or keep some small appliances going (chest freezer) during an outage. Easy to setup, quiet, and the peace of mind is well worth it.

The inverter works great so far. super easy to hook up. A little pricier than other inverters even on prime day but it's okay. It works well

This is a great purchase at the said price. Although I had issues with delivery. Customer service was excellent in helping resolve this issue

I will start with the manual. Was misleading and not very helpful so things got off to a bad start. I thought there was an issue right out of the box because the manual states that if there is GRD appearing on screen it is in protective mode. Well that is not true. It is just a way of telling you the invertor is plugged into the wall. Very confusing. When all was set up, and I unplugged from wall and was running on battery the GRD icon disappeared. Have the 3000w invertor hooked to 200ah battery running a 1.5 HP sump pump. In my case, the supplied wires are flimsy, and swapped with 1/0 gauge. Battery was charged, sump pit filled, electricity cut it, everything worked like a charm. Can't tell how long the battery will last in total power outage, but very confident will work in an emergency. Live in Montreal where basement has been flooded twice in two years. Confident this is another tool against the next flood

Works great

Very compact and good performance, pure sine wave as described. Battery charger continue until 14.6 V threshold then stays on stand by mode with 22W power consumption. For some reason this vevor review cannot upload pictures.

Love it! Runs my sump pump when I lose power.

I purchased this inverter about 3 weeks ago after a major rain storm. My 12v backup could not keep up with the input volume so I decided to use Another 120v pump for my backup. 3000w was overkill, but it has future expandability. My 3/4 hp pump only draws 960watts. The only think I would recommend would be more batteries or higher capacity battery. I purchased one 100ah battery. Also, any questions I had were promptly answered.

Hard to give much of a. Overall review because it hasn't been truly tested as of yet. We just installed a week ago and no trial as yet for performance testing .
