Good price for 2000Wh, but I can't this was ever $1500. Better name brands with similar specs are about $800, so decent deal.

I have this. Got it last winter to run my 3/4hp sump pump during outages and it works great for that. Seems to be of high quality and I've had no problems. I just wish it wasn't so heavy, but everything in this range is about the same weight.

How long could it run?

I didn't time it but it ran about 10 seconds every 2 or 3 minutes during a pretty heavy storm. In that time it handled the surge watts no problem. The display would dip to show a reduced time, but as soon as it was done pumping, it would go back to 100%, going down only slightly over true duration of the storm. The unit can also be plugged into wall power as a pass through, so it only uses the battery if there is an actual outage, charging otherwise.

I think if it was a full outage and the pump ran continuously, it may only last a couple hours. But usually the pump doesn't run continuously so I think I could get a lot longer running time from it. I may get a gas unit as a backup backup!

If you guy want a battery backup system for sump pump, you could buy SUMP PUMP INVERTER AND BATTERY 12V. Then connect them together with battery cables and tight down some bolts. It could SAVE 50%. Plus, it is easy to put in tight space. All-in-one unit like this one is BIG AND HEAVY.

Here is sump pump inverter and battery look like: https://ibb.co/MDRyGkJr

You could read and see many people reviews and pictures of their system on Amazon here:
