2.6.10. Solardrive
– General Parameters Menu
NOTE
This section is applicable to software versions starting from 4.050.
2.6.10.1. Overview
This menu includes the parameters determining the motor startup based on PV field solar radiation
conditions.
If the motor starts when the power made available from the PV field is inadequate to keep it running, the
motor will immediately stop. In order to extend durability of the connected motor, the number of false starts is
to be reduced to a minimum. For that reason, before activating the Maximum Power Point Tracking (MPPT)
algorithm and make the motor start at the speed determined by this algorithm, DC voltage delivered from the
PV field has to exceed a preset threshold (
P800 ) and this condition is to be maintained for the time set in
P801 ; this function will reduce to a minimum the false starts of the motor.
Once the motor has started, it is kept running until power made available from the PV field is adequate to
ensure that the motor speed exceeds the minimum allowable speed set in parameter
C800 (see section
2.6.9).

Function
If DC voltage is kept over this value for a value higher than P801 , the MPPT control is activated and
the motor starts.
When minimum voltage MPPT (parameter
P810 , see section 2.6.11) power is not adequate to keep
power over parameter C800 (see section 2.6.9) or voltage drops below the value ensuring the drive
correct operation, the motor stops.

Function
Time when DC voltage is to be kept over P800 in order to activate MPPT control and start the motor.
Each time the motor stops due to low power conditions, time P801 is applied again.
This parameter also sets the maximum number of restarts/hour forced by the connected pump. For
example, if the pump is to be restarted 10 times, parameter
P801 must be set to a value not lower
than:
P801 = 3600/10 = 360.0 s.
