Generator Start Option
This is how the “Generator Start” option for the inverter works:
•
If the option is “ON”, the generator start relay is activated
when the battery voltage falls below the “Low Battery
Threshold” level. “Low Battery Threshold” is settable from
the RE-ICC remote.
•
The RE-4500 looks at the Bulk charge current 4 minutes
(default) after switching on the relay if the AC input is
good and the system is charging.
•
The relay is switched off after the Bulk charge current has
fallen below a current threshold value for 4 minutes
(default). Once again, the “current threshold” is settable
from the RE-ICC remote.
•
The factory settings for “Low battery threshold” and
“current threshold” are 22.5 V
DC
and 5 A
DC
respectively for
the RE24-4500 system. For a 48VDC system the factory
settings “Low battery threshold” and “current threshold”
are 44V
DC
and 2.5
A
DC
This option is factory set to “ON.”
The relay is used
only
with a 2-wire generator start.
In order for the Generator Start function to work, the menu
item "Generator Strt" has to be “ON”.
Generator Start (when selected) is triggered by leaving the first
charging stage. The factory setting for the trigger type of the
first charger stage (named "STRT") is "<DC Voltage." This
value's factory setting ("Trigger Setting") is 22.00 Vdc for the
RE24-4500, or 44 Vdc for the RE48-4500. This means that the
generator start relay fires when the battery voltage is less than
this threshold.
There also is a setting for "Generator Wait" which is the time
the inverter waits for the AC input (generator or Grid) to
become valid. This means the following conditions need to be
met:
•
good L1-to-N and L2-to-N grid voltages
•
good frequency
•
phase-locked.
The factory setting for "Generator Wait" is 95 Seconds.
