Operator and Maintenance Manual for the PRO-Verter S 3000
PRELIMINARY
Automatic Generator Start/Stop (AGS) Function
The AGS circuit is used to start/stop an external generator, controlling it based on battery voltage.
When the AGS is active during hybrid operation, it should only start/stop a generator as a last line of
defense to ensure continuity of power is available to the load when the batteries are at low SOC.
The Generator Status LEDs located on the Faceplate provide real-time generator function
information to the Operator.
AGS Audible Alarm
The PRO-Verter has an audible warning that signals the generator has initiated the auto-start
protocol and is about to start. This provides Operators standing or working on or around the
generator with an opportunity to take precautions before it auto starts. This function can be disabled
for silent operations.
Soft Start
The PRO-Verter incorporates a “soft start” feature that provides advantages and protections. When
the PRO-Verter powers up, it starts in Invert mode. The soft start allows the output voltage to ramp
up gradually from around 48 VAC to 120 VAC in about 200 ms. This dampens the high inrush current
and concomitant voltage drop of inductive loads like motors. This will result in less mechanical
stress, less wear and tear, and increased lifetime of the PRO-Verter and the loads.
Cooling Fan Operation
The PRO-Verter contains two (2) variable-speed internal cooling fans that are controlled
automatically. The speed of these fans is determined either by the PRO-Verter internal temperature
or by the load on the transformer.
Two (2) additional cooling fans are integrated PRO-Verter case and turn on when the PRO-Verter is
powered up. They remove heat from the case interior.
Protection Circuits
The PRO-Verter is protected against fault conditions using protection circuits in the form of
magnetic/thermal circuit breakers. During normal usage, it will be rare to see any faults; however, if
a condition occurs that is outside the normal operating parameters, the PRO-Verter will shut down
and attempt to protect itself, the battery bank, and the AC loads. If there is a condition that causes
the inverter to shut down, it will be reflected as a fault on the LCD user interface. (Refer to the
PRO-
Verter Fault Diagnosis section to help diagnose and clear the fault condition.)
Note: Circuit breakers will vary among PRO-Verters according to customer requirements and
connection ratings.
