Generator Support
This is an extension of Vanner’s Automatic Power
Management feature. The default setting is 5 A
RMS
. In this
mode the RE-4500 “backs up” the power source to provide
peak power capability or “load leveling.” This may be to limit
the peak utility power draw or to provide a surge capability
that is greater than the other source can provide on its own. In
this mode the inverter monitors the input RMS current, and
when it exceeds the set value, first, stops consuming power
(charging) and second, begins providing power from the
battery into the load.
Generator Start and Grid-
Interactive
Many generators have poor voltage and frequency regulation.
The RE-4500 can be setup to operate with the wider regulation
that is sometimes required, but only when the inverter is not
connected to the grid. In cases where it is desirable to be
connected to the grid and also have generator backup, the
tighter voltage and frequency settings must be used. These
settings are password protected and can only be set by an
authorized installer.
Set Current
The system controller tells the RE-4500 to supply a constant
RMS current to the Grid. This is done until the battery reaches
its “Low Battery Warning” level, at which point Charging
begins. Charging will continue unless the system controller
changes the setting. The required trip points are used.
