Interested in your findings on the newer style.

Thanks oz. The explanation works for me and is now driving me to move to the EG design.
I have had some issues develop with the new PJ. After about 3 days the power started to blip (brown out) every 18-20 mins.
Turns out they run a beefy 12V fan off the pj board and the load is pulling the 12V and 5V rails to almost 0 instantaneously. This results in the "talking inverter"
to say "70% load remind"....
So to fix this, I cut out the 12V fan and fitted a 230V fan with a 45C thermostat on the transformer.
The Other two fans are 48V and run off a JUC-31F 45C thermostat fitted to one of the slow switch heatsinks on the mos board.
