Pump Overload	No light	Solid	This error occurs when there is sufficient power from the PV array, but the controller is unable to start the pump.	Check whether the hose is blocked or kinked (inspect the entire hydraulic system). Check whether the pump end is damaged or blocked. Check the water temperature and make sure it does not exceed the allowed maximum temperature for the pump end temperature class (applies to HR-pumps). Check the motor. Check the motor cable and motor extension cables for visible damages.	The controller will retry every 2 minutes automatically. You can also restart it manually by toggling the switch off and on.
