Enable Peak Power
Tracker
Displays as:
PPT Enable:
This parameter switches on and
off the Power Tracker function.
When the Power Tracker is on, the
inverter will regulate the bus
voltage to optimize output power.
When the Power Tracker is off, the
inverter will regulate the bus
voltage to maintain it at “PPT V
Ref” volts. 44 0 = Off
1 = On 1 1 0
Power Tracker Rate
Displays as:
PPT Rate:
This parameter sets the rate at
which the Power Tracker function
makes changes to the voltage
reference point as it tries to find
the optimal position. For example,
if the value of this parameter is
0.5, then every half a second the
power tracker will increase or
decrease the voltage reference
point to check if more power can
be produced at the new level. 45 Seconds 0.5 10.0 0.1
Power Tracker Step
Displays as:
PPT V Step:
This parameter sets the size of the
change the Power Tracker will
make to the voltage reference
point as it tries to find the optimal
position. For example, if the value
of this parameter is set to 1, the
Power Tracker will increase or
decrease the voltage reference
point by one volt at a speed of
“PPT Rate” to check if more
power can be produced at the new
level. 46 Volts 1 10.0 0.1
