Inverter life of ~10 years
#1
I've heard that the main reason that inverters only last about 10 years or so is solely because the electrolytic capacitors in them wear down.  Otherwise they could easily be designed to last 40 - 50 years.  Is that true?  If so why don't inverter makers design them so the capacitors can be more easily swapped out (kinda like a PCI express card attached to the motherboard or something like that in a PC).

Making them so they could be replaced would be like a vehicle being modular so the layman could replace parts. They loose money if the make them "easy" to repair.

The breakdown of electrolyte makes sense, though I don't know for sure.

I can't speak for other brands, but the caps in my AIMS are fairly easy to replace. Even with the most difficult to reach, it can be disassembled, replaced, reassembled in less than an hour.

Hmm... sounds like a reason to buy that brand. Then again maybe it's easy to replace the ones in the Voltronic inverters also.

I would think any of them are pretty much just a circuit board in an enclosure, equally as difficult to replace?

The larger caps are usually quite easy to replace, desoldering. These tend to degrade more slowly and you will not see any impact because it will impoact the output waveform and you may only notice if something connected to it fails.

The main issue is usually the smaller caps that lose capacitance and impact the gate voltage level on transistors, with the end result of "failure". These can be a bit more difficult to replace just due to the small size and if the PCB has thin copper layers these may separate off the board as well, making it a bit more hassle....

I have an old Victron. Would you recommend me replacing caps before something happens?

No, just wait...

You don’t repair your car without having any issue either...
