Companies often shop for industrial power inverters because they have products and services to provide constantly. In finding the right power inverter, these companies usually base their search on the price tag given by inverter manufacturers. The most economical ones chosen by most companies are the residential or commercial power inverters. Below are the differences between an industrial power inverter and a commercial power inverter:

- Housing. Power inverters can be damaged by falling objects, whether they’re commercial or industrial. Industrial inverters have more tightly sealed and more durable housings than commercial ones. It is vital that companies get power inverters made for heavy duty work environments. If they opt for commercial power inverters, the mechanism inside the inverter won’t be protected against highly damaging falling objects.
- The load capacity. Work in various industrial environments involves equipment that requires more power than ordinary appliances in homes. The load capacity of industrial power inverters is greater than commercial grade power inverters. If a company chooses a commercial power inverter, this inverter will malfunction easily because it is forced to carry a higher energy load than the load rating given by its manufacturer.
- Certificate (NEBS Level 3). The NEBS Level 3 certificate is always attached to industrial inverters. This certification is the highest level of protection against several detrimental operating environments. Such environments are those with heavy vibration, airborne contaminants, and unusual temperatures. Commercial or residential power inverters usually fail to function efficiently or fail to work at all.
- Lifespan. There is no doubt that industrial inverters have a longer lifespan than commercial power inverters. This is ensured by the NEBS Level 3 certificate, high load capacity, and high-performance housing. Industrial inverters just need to be installed properly and maintained regularly. If this is done, you can be sure that they can last for decades. Residential or commercial inverters usually last for a shorter period.
If you know that you need an industrial inverter, it is more practical not to choose residential or commercial power inverters so that you can save money initially. You are better off with an industrial inverter because it is far more durable and long lasting. It is fair to say that it is will worth every cent you pay upon your purchase. Get more information from credible and experienced inverter manufacturers so that you can end up with a good product. You can even have customized power inversion or power conversion if you need it. With this, industrial power inverters can truly help you with their long-term advantages in the long run.
why Commercial Power Inverters is Compact and Light if we try to Build Ower Own Watt Converter we need a Huge 10Kgs at lest transformer to handel the 100A Current but the commercial One weight only 4Kgs and soooooo Comapct How they do this ?

You can't use those transformers at high freq, this generally requires custom-wound jobs. There are a lot of "critical" factors here like wire gauge, core type/size, transistor drivers, board layout, and switching freq that require careful consideration. Skin effect is a limiting factor.
So you end up losing the problem of requiring a huge transformer core and a crazy amount of copper wire, but at the same time trade it off for a whole slew of new design issues.
Larger supplies sometimes use multiple smaller transformers rather than one large one.
Note the discrepancy between "peak" and "continuous" ratings in these inverters. The output is often exaggerated.
Honestly there's no advantage to the idea of building an inverter nowadays. It would be incredibly expensive and probably wouldn't perform for crap, not the first few tries anyways. If you don't know what you're doing you could blow it up dozens of times. There's a lot of reasons to learn how to build switching power supplies though.

But the AC must be 50 or 60 hz So what they do to solve this problem and if any one have a schematic or at least block diagram for a commercial inverter
They either rectify it to DC, then chop it at 50/60Hz to give a simulated rough sinewave - or, on better quality units, use it as a class-D amplifier and feed a 50/60Hz sinewave through the system, removing the high frequency carrier with an LC filter (which will need a fairly large choke).
