I bought one of these for my mother in-law after she had a power outage and was concerned with her sump pump if this should happen again. I set this up with a 12v 100ah battery and her existing 1/2 HP sump pump. Setup was simple. I tested it multiple times by unplugging the AC power and it worked perfectly. Her sump was cycling every 90 seconds for 5-10 seconds during a heavy spring thaw and rainy day. I left the AC unplugged and after an hour and 15 minutes the battery was down to 89% from the 100% starting point. Based on this she should get at least 10 hours of this fairly extreme runtime if needed. I'm sure it would run a lot longer under less intense cycle times. The sump load was about 425 watts when running, as reported by the battery's BMS.

Power cord shorter than standard, the 110v sockets are loose, this will prevent wall mount, your AC plug might fall down... when contacted seller, they suggested to "clamp" them, so, get ready for no support from seller. so far no issues with operation, but hesitant to keep this for long.

This is great inverter. I got it because my last 2 sump pumps flooded my basement. I got this and a alarm and 100amp hour lithium battery to hopefully never have it happen again. The build quality is good. The digital display is nice. You will need a power strip if you want more than 2 things hooked up. It can handle more.

Use it as a batter backup for my sump pump. Works great! Good price.

It's only been a few weeks but I have tested the inverter several times and it is working perfectly. Runs very quiet and cool. Has a clear display that shows input/output data, battery level and Watts being drawn. Ran my sump pump for 2 days before it began to 'beep' signaling low battery. My battery was fully charged in about 4 hrs. A bit expensive but worth it.

Unit functions OK but the output voltage either connected to AC source to the wall or the battery does not support an ice maker that consumes 225 watts! It makes 1/4 of the ice it should make. Does not hold up to the voltage properly there fore appliances performance of greatly affected. Would not buy if going to us medium to larger appliances.

Transport selon l’estimation, emballage parfaite, on peut constater tout de suite en le déballant par son poids et le fait qu’il y’a aucun son de vis lousse par exemple que le produits semble de qualité. J’ai fait tous les test nécessaires et son fonctionnement est parfait jusqu’ici. On verra dans le temps pour la durabilité. Je vous promet de vous revenir dans un an ou deux. Puis qu’à ce prix, il est raisonnable de s’attendre à ce qu’il dure au moins cinq ans. Seul ombre au tableau, aucune information ou description en Français. J’ai eu deux questions et chacune on été répondu avec clarté en anglais en moins de 24 heures. Finalement un dernier point pour amélioration futur, dans le dépliant, aucune information à propos des fusibles de rechange fournit dans l’emballage et encore moins comment les remplacer ! Bravo Voonky.

On the product description, it states this inverter will undercharge lithium/lifepo4 type batteries. When I purchased, I was using an AGM 95AH. According to the manual it comes with, it's compatible with lifepo4 batteries, so I decided to give it a try. Immediately started charging at a full 14.4-14.6V and maintain at 13.6V. Seems fully compatible with Lifepo4 but your results may differ.So far I've been very happy with this inverter. I prefer to have a 2500 Watt capacity to be fully compatible in power ratings with a 20 amp outlet, but this was the best available at the time of purchase. We had a power outage in a storm that required the sump pump to run and had no battery backup so I had to use a solar generator to get through. Had we not been home it would have been a flooded basement. This is the fix to that problem.I've done several tests on this for the power switching and load, running a shop vac at 1200 watts and a deep freezer at 125 watts at the same time with no issues. The 100AH Lifepo4 battery maintains a constant voltage for the inverter to output a nice sinewave. Plug it back in to the mains and everything stays smooth. I'd recommend this inverter for anyone trying to accomplish the same goals, or wanting auto switching built in UPS style inverter. Works well for it. Sump pump and deep freezer should last 4 or so days of normal operation before it'd need charged.

I plugged it in overnight and it did not charge.
