Status
Description
No Stack Comm-
PT
(F20)
The PT controller will not run because stacking has been enabled (DIP
switch 10 is set to UP), but the controller is not receiving any network
communications from the Magnum inverter.
Stack ComLost-PT
(F21)
The controller was previously communicating on the network, but now
it is no longer receiving any communications from the Magnum inverter
or from another controller.
Note:
The controller continues to run with
this fault
.
Stack Switch-PT
(F22)
The PT controller is not able to run because the controller’s stacking
address has been incorrectly set.
Battery Volts-PT
(F23)
This fault indicates that there is a large battery voltage difference between
the master controller and a slave controller. This fault is only allowed
on a slave controller and displays on each slave controller that detects
a 4% or greater battery voltage difference from the master controller.
Note:
The controller continues to run with this fault.
Unknown Fault ##
The PT controller turned off because the PT controller has sent a fault
code that cannot be determined by the ME-ARTR router.

The controller is in the Absorb charge stage, regulating the current from
the PV to maintain the battery at the Absorb target voltage.
Bulk
The controller is in the Bulk charge stage, providing maximum current
from the PV to the battery.
Charger Off
Charging in the PT controller has been disabled manually by selecting
Charger Off
from the

menu, or may be caused by a
controller fault.
EQ
The controller is in the Equalization charge mode, regulating the current
from the PV to maintain the battery at the Equalize target voltage.
Float
The controller is in the Float charge stage, regulating the current from
the PV to maintain the battery at the Absorb target voltage.
