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

[jay]

HI John,

Yes Its my understanding that they are backwards compatible.

So put the newer inverter as master, older as slave should work.

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?
