Upgrading Generac PWRcell Battery

See Figure
battery modules are stacked 2-deep on three levels,
allowing for up to 6 modules to be connected in a series.
In systems with less than 6 modules, Generac PWRcell
can be upgraded with additional module up to a total of 6
modules.
Whenever upgrading Generac PWRcell:
• A Vset Function must be performed. See
Vset Function.
• A module spacer must be installed on any single
module shelf. See
(Generac PWRcell 3 and Generac PWRcell 5
only).
