The HQ-197K1500W-24 Controller General Information

Features

The HQ-197K1500W-24 solar pump controller is designed with the high standard of reliability expected of products. The controller attempts to drive the pump and motor to deliver water even under adverse conditions, reducing output as necessary to protect the system components from damage, and only shutting down in extreme cases. Full operation is restored automatically whenever abnormal conditions subside.

Inspection

Before you begin, receive and inspect the HQ-197K1500W-24 solar pump controller unit. Verify that the part number is correct and that no damage has occurred during transit.

NOTE: HQ-197K1500W-24 solar pump controller is one component of a HQ-197K1500W-24 solar pumping

system which has other two optional components, solar array and Brushless DC Motor pump.

Protection Features

Electronic monitoring gives the controller the capability to monitor the system and automatically shut down in the event of:

• •  Dry well conditions – with low level switch
• •  Bound pump – with auto-reversing torque.
• •  High Voltage Surge
• •  Low Input Voltage
• •  Open motor circuit
• •  Short circuit
• •  Over heat

NOTE: This controller provides motor overload protection by preventing motor current from exceeding rating current and by limiting the duty cycle in the event of low water level. This controller does not provide over temperature sensing of the motor.

System Diagnostics

The HQ-197K1500W-24 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.the fault condition. If possible, the controller will try to restart itself when the fault condition subsides.

Motor Soft-Start

Normally, when there is a demand for water and power is available, the HQ-197K1500W-24

solar pump controller will be operating. Whenever the HQ-197K1500W-24 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.

Over Temperature Foldback

The HQ-197K1500W-24 solar pump controller is designed for full power operation from a solar array in ambient temperatures up to 45℃. In excess of 45℃ temperature conditions,the controller will reduce output power in an attempt to avoid shutdown. Full pump output is restored when the controller temperature cools to

a safe level.

Level Control Switch

The HQ-197K1500W-24 solar pump controller can access two water level switch detects remotely control the pump automatically. Level switch for HQ-197K1500W-24 solar pump controller is optional, not mandatory.
