so I related how my failure to correctly torque down a cable led to a 2g cable getting very hot (no fire thank god). but what I did not relate was that right before this, I toasted a generator.
so I have 10kw diesel 3 phase genset that i use to power welders (real ones, not 120 volt craftsmen units) as well as compressors and car lift. i also have it hard wired into my inverter but only at 120. the inverter cannot handle 3phase power as its 120° out of phase compared to 240 split phase which is 180° out of phase. it causes the inverter to overheat when trying to rectify the phases. but you can use 120 input, but you can only charge at half of the rate compared to 240. so 30 amps at 48 volts. I also have(had) a gasoline makita genset from the early 90's that did 20 amps at 240 split phase.
so, the 10kw is hard wired but you can shut it off via its circuit breaker. the 5.5kw makita was a 240 lug, and it has its own breaker. so dumb ass me is charging up the new battery banks with the diesel genset while using the compressor and the lift. but it was taking forever and the temp sensors on the inverter were reading fairly high so i decided to start the smaller 240 genset and allow it to charge while using the 10kw to run the 3 phase stuff. yep.. forgot to shut off the breaker ont he 10kw and it smoked something in the makita. problem is its a 30+ year old genset and parts are no longer available.
my first thought was the diode set, jacks small engines has them listed but cancelled my order saying the part was no longer available. so i found one on EBAY used, and tried it.. no dice, the genset only makes 70-80 volts per leg when it should be making 120 per leg.
any ideas? thinking i might need to just junk it as parts are no longer easily available, which is sad as it only has about 300 hours on it. all of which I put on it after buying it used but stored for over 30 years.
thing is I do not even need it in reality as other than commissioning my new battery banks the panels provide more than enough and the bank is sized to carry me through 7 days of zero output... the 10 kw will charge up the bank, its just slower.
oh and this was a beer involved accident...
