24VDC PRO-Verter 5000-120 AGS Operator Manual
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.
• Fans run at full speed if the FETs or the power transformer reaches 80 °C (176 °F), or the inverter
is running at 100% of its rated load.
• Fans run at medium speed if the FETs or the power transformer reaches 60 °C (140 °F), or the
inverter is running at 50% of its rated load.
• Fans run at low speed when the inverter is running at 25% of its rated load.
The fans shut down when none of the above conditions are met, or if the battery voltage drops
below 20 V.
Protection Circuits
The PRO-Verter is protected against fault conditions using both internal protection circuits and
external circuit protections 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, it 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 with the
indicator LED in a steady-on state. The LCD will display an error message with the fault code/
reason. (Refer to the
section to help diagnose and clear the fault
condition).
Note:
Circuit breakers will vary among PRO-Verters according to customer requirements and
connection ratings.
EMI Circuit Protection
The AC power output of the PRO-Verter is filtered using a high performance 2-stage EMI filter inside
the PRO-Verter to reduce high-frequency interference.
Circuit Limitations
When the PRO-Verter is selected for duty in an application, it must be configured to work properly
and safely between the load and any AC power source that is connected to it (generator or grid-
utility). The PRO-Verter manages and distributes AC power IN and OUT through a network of cables
and connections. A series of circuit breakers protect the PRO-Verter, as well as the connected loads
or generator, from overloading.
If circuit breakers on the AC INPUT or AC OUTPUT are tripping, it is likely that the load has
exceeded the available current of the PRO-Verter and/or the generator.
