System Setup and Operation Manual for ATSC MS3 L0
“Overload” Conditions
Over loading of the System can occur under the following conditions:
• Load AC power demand is greater than the inverter’s rated output.
• Load AC and DC power demand is greater than the connected AC source (generator or grid
utility).
• Load AC power demand is greater than the AC INPUT setting, which may cause the PRO-Verter
to disconnect from the AC source when in pass-through (charging) mode.
• Load AC and DC power demand is greater than the output of the connected AC source
(generator or grid utility), causing it to shut down.
In each of these scenarios, the solution is simply a reduction in the total load demand (AC and DC).
Use the AC and DC METERS to confirm the load is reduced to prescribed levels and proceed with
normal operation.
Load Support (If Equipped)
Load Support function is used to support two models of operation:
1. Load Support Model
2. Peak Power Model
Load Support is an automatic function of the PRO-Verter that combines power from a generator or
grid AC source with the inverter’s AC output to briefly support high AC loads that exceeds the AC
source’s or the PRO-Verter’s rated AC power output.
It is typically used in operations where the PRO-Verter is connected to a generator or Grid AC
power source that is rated for LESS AC output than the inverter output power rating of the PRO-
Verter.
It automatically engages once the load exceeds the AC INPUT setting (FAVS 03), and because it
requires power from the batteries, it should only be used if the excessive loads are brief in duration
and intermittent in scope.
For Load Support to function, the PRO-Verter must be connected to an active AC power source. It
cannot engage if there is no active external AC power source.
The PRO-Verter can also be configured to perform Load Support as a manual intervention method
when conditions warrant. This is also referred to as the Peak Power Model.
Consult the PRO-Verter I-Plate to determine if the PRO-Verter is equipped with the Load Support
feature and for specific instructions on manual engagement of Load Support for a particular
application.
