10.2.4.4 PT Remote Power Statuses
The following "Power" statuses show the status of the controller's Power Point Tracking.
Note: The power status codes (example: "P04") listed below only appear on the PT's display to
identify the particular PT power status.

Using a PT Controller: Operation/Monitoring

Table 10-5, PT Remote Power Statuses

Power Maximized (MPPT is On) – The MPPT circuit is delivering the
maximum power from the array to the battery.
No Power Output – The PT controller is turned off , the controller is
sleeping (during night-time), or a shutdown fault has occurred.
Battery Voltage Regulation (Normal Current Regulation) – The PT
controller is regulating the current to the batteries to keep them at their
target voltage in the Absorb, Float or Equalization stage.
Battery Current Regulation (Normal Current Regulation) – The PT
controller is regulating the current to the battery to ensure the control-
ler's maximum output current is not exceeded.
Power Limited (Internal High Temperature) – The temperature in-
side the PT controller is getting high, so the output current is being lim-
ited in an attempt to prevent the controller from shutting down.
Power Limited (Internal Frequency) – The controller includes a vari-
able frequency converter—this power status displays if the output cur-
rent is being dialed back to prevent the frequency from going either too
high or too low.
Info: If the PV voltage is sized too close to the battery voltage,
a Limit: Int Hz power status can occur. If this status occurs
often, the array may need to be re-confi gured to increase the
PV voltage.
Power Limited (Above Voltage Regulation) – The voltage on the
battery bank is above the target voltage set-point. Generally, this is due
to an external charger being set to charge at a higher voltage level. The
PT controller is limiting the output current in an attempt to prevent the
battery voltage from increasing to a voltage level that would trigger a
High Battery In (F04) fault.
This status message (with the hex code number) displays when the ARC
remote cannot determine the power status code that was received.
