When the maroon on Youtube complained the USED and modified inverter under nspection was dirty "the bloom was off the rose". No cordless screwdriver. I waited while he fiddled. I finished 70% of "The First Review" More than enough for me.
Inverters are reactive. Guesswork and assumptions are worse than worthless.
Inverter POTENTIAL meaning PERFORMANCE is tested one way: An oscilloscope is connected to present waveform. Then the unit is progressively wattage loaded.
When an inverter approaches it's limit, voltage waveform becomes more and more distorted. I have seen sawtooth wave form. Over burdening brings straight square wave be it a $299 special or $2999 flagship inverter. I did not see even a handheld scope meter. Was one used?
Was a thermocouple scanner employed? Was p/n FET junction versus heatsink Delta T temperature (differential) established?
Was the cooling fan CFM mentioned? Ball or sleeve bearing?
The "expert" complained about "multiple chokes" instead of a single choke. Does the "expert" understand multiple chokes will dissipate a lot more heat if necessary?
Did the "expert" mention the possibility of tossing the morphidite AC plug and substituting good nylon body receptacles. A 20-amp duplex and maybe 20-amp twist lock?
Was the expert aware that having a fan on one end and chokes on the other, creates an oven. It would take a 300 CFM fan to cool the far end. The answer does not lie in fitting a Sikorsky grade cooling fan but installing circulation fans within?
"Name brand capacitors". Ever see a large electrolytic cap without a name brand on it? BTW, a 50 volt rated cap is marginal -- way way marginal. A 100 volt Panasonic ESR cap with a 125c rather than an 85c rating is night and day.
Did the previous owner attempt to jump start a Burlington Northern locomotive which would have "bulged" that so-noted capacitor.
ZERO information on the FET specs.
Trace hard anodized their heatsinks 30-years ago for a reason. The "expert" was blind to this.
Output wattage potential to ultimate battery charging amperage potential can be evaluated. Trace's 2500SB was rated as a 2,500 watt inverter. It had a 120 amp battery charger.
Compare that to the Great Wall 5000. Does something jump out at you?
To me "The Big Lesson" here is NOT the inverter. It is the seriousness in which a Youtube "Expert Analysis" is being taken.
I did read some other "expert's" reviews. They were all woefully lacking in substance while rich as whipped cream with opinion.
E CAVEAT EMPTOR reviews. Even this one...
