Review on 🔌 2200Watt DC 12volt to AC 120volt Pure Sine Wave Power Inverter with Dual AC Outlets, 2.4A USB Port & LED Display Remote Controller - Ideal for RV Trucks, Boats, and Emergency Power Supply【3 Year Warranty】 by Joe Jordan

I bought this inverter to use with a large 200ah battery to provide backup power for my fridge and other essentials when the power goes out (thanks PG&E). I wanted a pure sine wave device to power my fridge and microwave with clean power. These devices require a pure sine block as non-sinusoidal blocks cause additional wear and reduce the efficiency of the devices. The reason I chose this inverter was the 36 month warranty and because it seems to have the best reviews of any other inverter. It looks well built. During the first test, everything went great. I hooked up a shop vacuum as a test and it worked fine as if it were plugged into the wall. Current consumption and battery voltage 12.4. At the same time I connected a clamp meter to one of the battery posts and it showed a current of just over 130 amps. That corresponds to an efficiency of about 80%, which is not bad. It's also good that I felt the wires and inverter, and they weren't warm at all! The supplied cables are the correct size and the inverter has an adequate cooling system. The fans came on as soon as I turned on the vacuum and turned off as soon as I turned off the vacuum, so this inverter is absolutely silent at minimal load, unlike other inverters that have the fan running all the time. what can. As for the standby current, it draws around 600mA when initially switched on with no load, which is not bad for an inverter of this size. Interestingly, however, if you connect the inverter to a load and then remove the load, it still maintains a current draw of around 1.2 amps. I had to cycle the inverter to drop the current to 600 milliamps. I'm not sure why that is. Also, I measured a current of about 60mA with the inverter fully off. So if you just plug in the inverter, whether it's on or not, it will draw a small amount of power, although that amount is so negligible that it's negligible, and I'd say that's normal. If you have connected a charger or solar charging system at least once a month, you don't have to worry about keeping this inverter connected to your battery 24/7. All in all, first impressions are great. and it seems like it fits my needs. Time will tell how well this inverter will hold up!
