The RHINO SOLAR PUMP VFD is Designed to Deliver Water in Remote Locations Where Access to Reliable AC Power May Be Uncertain or Non-existent Also It is Suitable for All the Loactions. This Controller Operates Seamlessly on DC Power Supplied by the Pv Array. During Sunny Days, the Solar Pumping System Can Consistently and Efficiently Move Water. In Instances Where There Are No Batteries or Other Energy Storage Devices, It is Advisable to Pump Water to a Reservoir for Future Use. Water Sources Can Range From Natural Bodies Like Rivers, Lakes, and Wells to Specialized Waterways. To Manage the Pump’s Operation Effectively, a Float Switch Can Be Installed in the Water Tower.
This 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 a High Risk of Equipment Damage, the Controller Will Protect the System and Display the Fault Condition.
The Solar Pump Controller is a Variable Speed Motor Drive Designed to Operate Various BLDC and  AC Induction Pump Sets Specifically Engineered for 1HP Pumps.

Solar VFD Features:

  • Operates 2 Types of Motors, MPPT (Maximum Power Point Tracking) and 3 Pahse AC Induction Solar Type (V/F).
  • It can Run Low Voltage with TWO – THREE ( MONO – Monocrystalline / POLY – Polycrystalline ) Solar Panels.
  • It Accepts Direct Input from Solar Panels within the Range of DC 60V To 150V.
  • Continuous and Highly Efficient Power Tracking at 99%
  • Ideal for 1HP AC Induction Motor or BLDC Motor.
  • Rated to Handle up to 1000w Input DC Power with 10amps of Continuous Input Current.
  • Operating Flawlessly within an Ambient Temperature Range of 0 to 60 Degrees Celsius.
  • This System Prioritizes Safety with Built-in Features Such as Reverse Polarity Protection, Over-Temperature Safeguards, Under-Voltage Protection, and Overload Protection.
  • Float Sensor Inputs can be Connector to Control the Water Level in a fixed Tank System. In case a Float Sensor is not intended to be used Please Hook up a Short Circuit Wire between 0V / Reference and TL Input.

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.
