Update
I was watching the Australian open a few weeks ago, and saw highs at the courts of slightly over 45C. That is warm!
Meanwhile, we had 29 consecutive days of below zero weather, due to a shifted polar vortex.
This is a record for this area.
This also lead to higher than normal snow accumulation.
So not bad compared to lots of other areas, but more than we expect.
Regarding the inverter, I have done a few things.
-the 8 Fets (Q5-Q8 and Q13-Q16) were blown, so I replaced those and the the inverter ran.
-I then also replaced the driver transistors, gate resistors and thermal pads just because.
-I had a spare power FET and aurduino board mostly built, so I completed those and
made another aluminum mounting plate for the power FET board. These new boards were
installed into the inverter, and the old ones kept as backup.
I had a piece of audio gear that drew a huge inrush current (120A at 120v).
I modified it so most it draws now is about 10 amps. This allowed me to greatly reduce the over current trip point of the inverter.
Things have been running fine for the last few weeks, although the frequency
on this new arduino is not particularly good.
So all is good...
