Review on 🔥 FLAMEZUM 4000Watt Pure Sine Wave Power Inverter - 12V DC to 110V 120V AC, 8000Watt Peak Power, Remote Control, 4 AC Outlets, Dual USB Port - for CPAP, RV, Car, Solar System, Emergency by Scott Channell

I took a point, the wattmeter is not calibrated correctly at all. I have just connected a Flamezum 24V/2000W sine wave inverter to my new barn solar system. Tested on my camper. Deserves fridge, TV, charger without turning on the fan. (350 watts 120v.) Turned everything off. I held my breath and turned on the 15,000 BTU rooftop air conditioner. BINGO. Fired up right away. I went into the barn and checked. Consumption 1800 W. The fan works. Let it run for 15 minutes and the A/C will go through its normal thermostat/temperature circulating routine, then start again after about 10 minutes. The standard wires were room temperature, as was the inverter. I have no plans to use a Flamezum inverter to run this air conditioner, it was just a test. It is planned to run at least 110 V in the house. Fridge, light etc. I have a 3500w inverter generator that can be used if needed. My rule of thumb is that the inverter should be at least 40% larger than the heaviest load you can put on it. I would use a 5000 window unit or a 9000 BTU mini split air conditioner. From the very heart of Ercot's Texas network. There's nothing worse than spending 4 days in an 8 day winter storm with no bloody energy. And gas stations are closed.
