Finally got 1 of my mainboard/control board sets from Sean at Genetry. After apparently losing the first shipment. So this isn't even the control board I sent to him in the first place. It is what it is. No idea when I'll get the other set. He's already forgotten it once. I'm beginning to think he is in over his head with his business.
Anyway, this set was supposedly tested for over 12 hours. Hopefully it is good to go.
I now have it installed and everything hooked up except the 12v fan circuit. The main 48v fan has been swapped out for a 12v fan, and the 3 small fans on the transformers are also 12v. Those will all be powered off of the control board's 12v fan connection.
Yes, all powerjack v8 and v9 control boards only output 12v for their fan circuits now regardless of the inverter's rated voltage. My new dual lcd model has 48v fans but they don't take power from the control board. Nothing plugs into the fan ckt on that one. Funny, the older model control boards wouldn't even run without a fan plugged in.
Back to this inverter, either the control board or my heatsink temp control will run the four 12v fans. Powerjack's thermal switches or my transformer temp control will run the 2 stock 120mm 48v transformer fans. My controls usually do the switching on of fans, as I set the setpoints so they come on sooner. There is a manual fan switch for the 12v fans but I need to add one for the 48v fans also.
What's left to do is removing the output endplate to improve airflow. I've got it pulled loose and am waffling on what to reposition and what to just eliminate.
