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

[Kirk Herander]

Do you have the proper hub 10.3 installed? And are the jumpers set
correctly? Mate3S? it almost sounds like the slave is set in the Mate not
to charge. And if not plugged into the correct hub port, stuff like this
happens also. And the Mate3 might not work properly with newer inverters,
as I remember.
