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

[Sindelar Solar]

John,
I've never faced your situation so can't address it directly. However, I 
don't think matching firmware requires replacing a control board. Can't 
you just update the firmware to the latest for that legacy product using 
a Mate3?
The firware for these should be available at
