Modes of Operation
The RE-4500 operates in three modes:
•
Inverting
•
Charging
•
Grid-interactive
This section will describe these and any sub-modes within
them, and their respective faults.
The RE-4500 is designed so that if there is a fault the RE-4500
will shutdown. If the fault condition goes away, the inverter
will restart after 5 minutes in “Auto Recovery” mode.
The next Sections will describe these three modes of operation.
Inverting
When the grid is not available and the batteries have enough
charge then the RE-4500 generates AC power. The 240 V
RMS
three-wire output will deliver a continuous 18.75 A
RMS
@
25
°
C. Also, if Charging is not enabled and AC Power is
present, then the inverter will run phase-locked to the Grid.
Load Demand (Load Discover)
The inverter does “load demand” to improve efficiency when
the small inverter is not installed and the option is enabled. The
default settings are “Load Demand: ON” and 10 W to enter
load demand (start pulsing) and 75 W to leave load demand
(generate a constant voltage). When the load falls below 10 W
there will be a 5-second delay (default setting) before pulsing
begins.
