Thank you. I'll will mail him.

Old age is a big one. Most electronics have this problem. They have electrolytic capacitors, which age the fastest, especially where higher temperatures are involved. I have had many an appliance blow up because the capacitors are too close to the hot parts, and this includes computer motherboards and internet routers. This was also one of the big issues with the earlier Axpert MKS units. They had capacitors on the DC bus rated for 63V, 2000 hours. When they ran hot, they blew up every 6 months, which is roughly 2000 hours at 12 hours a day 🙂
Of course this issue is one of design. The designer decides how long he wants it to last, and selects the component accordingly. Over time, the engineers, bean counters, and support dept. reach some sort of an agreement and that is what you get.
Saw a report of a Victron unit that failed its relay test repeatedly. Turns out a bug managed to sacrifice itself across the Life/Earth contacts.
Accidentally wiring 23VAC to the output... yes that can happen. Accidentally wiring 24V to a 12V inverter, I've seen that too. Reverse polarity will destroy some units too (adding a diode causes too much of a power loss, and adding a reverse diode/FET plus fuse adds cost). Some inverters are pretty robust though, and it takes real ingenuity to get it wrong.
But let me say this: A good inverter should never ever blow up because it was overloaded. A good inverter switches off when it is overloaded. You fit breakers to protect the cabling against overcurrent, but never to protect the inverter. It is pointless in any case: A breaker can take tens of seconds to trip. The inverter must be able to deal with an overload and protect itself. This is non-negotiable.
