Inverter repairs

I am tossing around the idea of offering an inverter repair service. Or buying broken ones, fixing and reselling them.

This would only be for the US market as I think shipping international would be cost prohibitive.

How many people break inverters in here?

If you're inverter blows up do you no longer trust that brand and use it as an option to move into something different?

Any thoughts are welcome.

I think this is a good idea. Most of the time it's just FETs that blow up.

If you do this, I think you should try expanding into other forums as well to try to get a larger audience to get the old units from. I think there's only been a handful of failures here. I suppose eBay or Craigslist could also be potential avenues.

I'v gotten a few from Ebay so far and had success. No luck yet on selling them, but this is a very new plan. I'm trying to not put the cart before the horse.

On a separate note, how do I add a picture to my profile. I'm looking around for it now.

*edit* I found it and now I have an image

Nice idea... some ideas and thoughts that may be helpful..

Try and find a recycling source that gets failed units (IT supplier) where you could get them for free / very very cheap.

Offer modifications to re-sell them as inverter units for powerwalls (e.g. external Andersons connections) because as repaired "Computer use UPS" units the business market will avoid them, so your left with the consumer market. The pwerwall / alternative use may see a far bigger market than computer use...

Some boards with have tracks blown off the PCB (when used with an external powerwall) as the fault currents are higher so offer a repair with no guaranteed repair, in case the PCB is multi layer and the central layers have been blown through... Sometimes the units may just blow the charging circuit and still work as an inverter... The charging circuits are usually very low current so not that geat for powerwalls.. and the voltages can't be changed easily (another custom mod)..

Accumulate unrepairable units as stock spares as a number of the FET's will be compatible on voltage and switching time / currents.
