240 rms is about 410 peak to peak, 480 is like 820 +/-a bit. Can get to higher via capacitance doublers, but 800 and 1200 are commercially available although expensive and need a substation. Up to a Kwatt just needs a heatsink or paralleling igbts. Got 300 kw switched load under the hood of the ranger being cooled with two computer fans even on a hot Reno summer day. My motor is the heat limited item.
20 year lifespan on my power electronics, so far. On the DIY solar forum I frequent, the not cheapo chinese inverters have a 20 year life, or so the forum indicates, but that isn't MTBF. Jury is out on vicious EMP events, evidence so far is erratic and inconclusive. Tree falling on system is more hazardous to solar generation so far.
