[RE-wrenches] 2nd VFX3648 added to double charger rate

[Maverick Brown]

Is the wiring 120/240 and Series or Parallel stacking? If parallel, one of the stacking options assumes you have a x-240 transformer and the slave is silent unless power save is high enough. Pick the parallel that keeps both inverters on at the same time   This is kinda foggy since it has been a while.

The Mate3(s) is easier.

I read in the manual that both inverters must be the same firmware revision.  Once hooked up I found that the added inverter was rev #68 and the original one rev 61.  Would it be possible to switch which inverter is the master and have the newer one recognize the older one.? Otherwise is my only option to put a new control board in the original inverter? And possibly also in the new one.  Anyone know what the latest rev or last one was?
