IN IN4397CH2013A
[0001] A method of operating a pump in pump system comprising a photo¬voltaic panel system (1), an inverter (2) electrically connected to the photovol¬taic panel system and a motor (3) driving the pump and electrically connected to the output of the inverter (2). The method comprises setting a voltage limit for the inverter (2), monitoring the voltage produced by the photovoltaic panel system (1), operating the inverter (2) for rotating of the motor (3) when the voltage produced by the photovoltaic panel system is above the voltage limit, and disabling the use of the inverter (2) when the voltage of the photovoltaic system remains below the voltage limit.
