Review on 🔌 GIANDEL 3000Watt DC 12V to 120V Power Inverter with LCD Display, Remote Control, USB Ports, and AC Outlets - Pure Sine Wave Technology by James Davis

have been working for a week now and the best I can say without having a scope is that my digital clock is showing the time, that in itself tells me some Pure Inverted Food causes time to pass slowly and up to an hour or more of time is lost each day. The wattage requirements work fine and the voltage is 121 and is holding up pretty well. Maximum voltage confirmed: 16 volts is the shutdown for this inverter and 15.9 is normal for operation. Why do I need this stress? Li-ion 18650 batteries. Yes, finally an inverter that can withstand 95% of the voltage that a 4S device can have. I almost doubled the capacity by being able to charge the batteries almost fully, and not fully charged means the batteries last longer, only charging up to 95% of the max charge is suitable for me. Most conventional inverters only allow up to 15.2 volts and cut out due to over voltage, I have one as a spare that cuts out at 15 volts which is totally useless for a Li-Ion 4S. My setup for the voltage range is: 13 volt auto reverse charging starts on low sun days 1000 watts at solar power with a not so common 20 amp CC CV buck converter, there must be a fan and more heatsinks Constant maximum load 22 amps, otherwise it will fail due to overheating and exploding caps. On the board, the inductor gets incredibly hot, or one of the mosfets overheats and fails. I also had one of the marks on the board that caused the mosfet to burn out and I had to fix that and replace the mosfet. Guys, I've burned over 10 of these just trying to figure out what works and what doesn't! Now I have 2 of these that have been working fine for the past few months, one for reverse charging and one for solar charging. 15.9 volts is the high voltage breakpoint, which is way better than my old 15.2 volt inverter.
