Dave,
Yes, they are interchangable and using it will make the inverter an off
grid version. I have done that to several grid tie versions as I do mostly
off grid work. Yes, the AC Bd and the FET board and transformer are all
the same.. The GVFX control board is for grid tie and usually does

Any good Lithium ion phosphate tech battery has a BMU that protects the
battery from over charge and over temp, different brands may have different
ways and values, In most cases the inverter battery temp sensor is not used
on a LFP batteries and the BMU will control both battery
The only time I worry about temperature in a FLA is during a corrective EQ
as opposed to a preventative EQ.
If the cells are really way off I just EQ at the recommended V for 5+
hours and then measure SG. I have no worries unless the temp is outside the
max recommendation. At that point I would

I got this text from a friend. I do not know the years
on any of this.
The control board on a gvfx 3648 went out on me and a
friend has a spare vfx 3648 control board that I can borrow. Does anyone
here have actual experience with using a vfx control board in a gvfx
inverter?
Greetings Wrenches,
I have an unusual request. I have a top of pole rack that was designed
incorrectly for the intended modules and i am looking for a dimensional
match in a 60 cell module. If you happen to have 12 modules that fit the
bill, please contact me off list. (Racking is designed
Folks,
A few questions:
When charging a FLA battery, even though we use a three stage charging
regime controlling voltage/current, is it not true that the real goal is
to avoid excess temperature rise inside the cell generally? Do we worry
that excess current will cause localized excess
