System Diagnostics:
The solar pump controller continuously monitors system performance and detects a variety of abnormal conditions. In many cases, the controller will compensate as needed to maintain continuous system operation; however, if there is high risk of equipment damage, the controller will protect the system and display the fault condition. If possible, the controller will try to restart itself when the fault condition subsides. See Diagnostics and Troubleshooting section for a list of Fault Codes and corrective actions.
Motor Soft-Start Normally:
When there is a demand for water and power is available, the solar pump controller will be operating. Whenever the solar pump controller detects a need for water, the controller always “ramps up” the motor speed while gradually increasing motor voltage, resulting in a cooler motor and lower start-up current compared to conventional water systems. Due to the controller’s soft-start feature this will not harm the motor. It will help to extend the motor lifetime.
Over Temperature Fold back:
The solar pump controller is designed for full power operation from a solar array in ambient temperatures up to 90°C. In excess of 90°C temperature conditions, the controller will switch off the output.
Level Control Switch:
The solar pump controller can access water level switch detects remotely control the pump or reservoir automatically. Level switch for solar pump controller is optional, not mandatory.
