800W Doyin DYS-90 DC Solar Pump Controller – Solar Input, Automatic Control, Pump Protection

Product Overview

The 800W Doyin DYS-90 DC Solar Pump Controller is designed to control compatible 800W DC solar water pumps, providing efficient pump management using power from a correctly sized solar PV array. As a dedicated DC controller, it is particularly suitable for solar-only water pumping installations where grid electricity is unavailable, unreliable or unnecessary.

With its 800W control capacity, the DYS-90 is suitable for borehole pumping, farm water supply, livestock watering, irrigation and storage-tank filling. It can also support automatic water management when correctly integrated with compatible water-level sensing equipment.

Macire supplies the Doyin DYS-90 with technical guidance for matching the controller to the pump and solar array. Correct voltage, power and cable sizing should always be verified before installation.

System Architecture & Configuration

800W DC Pump Control

Purpose-built for correctly matched 800W DC solar water-pumping systems.

Solar PV Input

Designed to receive DC energy from an appropriately configured solar PV array for direct solar-powered pumping.

Automatic Water Control

Can support automatic pump start/stop operation when correctly integrated with compatible tank or borehole level sensors.

Off-Grid Configuration

Suitable for locations where water pumping needs to operate independently of normal grid electricity.

Technical Specifications

Exact PV input voltage, operating current and protection parameters should be confirmed from the DYS-90 nameplate or manufacturer documentation before system sizing.

Installation & Engineering Notes

The DYS-90 should be installed in a dry, ventilated and protected location. The connected pump must be electrically compatible with the controller’s 800W rating.

The solar array must provide the appropriate DC voltage and sufficient power for the complete pumping system. Correct PV polarity, cable sizing, earthing and electrical protection are important for safe operation.

Where automatic tank filling or water-level control is required, compatible sensors should be correctly positioned and connected.

Macire can provide guidance on matching the 800W pump, DYS-90 controller and solar-panel configuration.

Care, Maintenance & Operations

• Keep the controller protected from rain and moisture.
• Maintain adequate ventilation around the unit.
• Inspect solar and pump cable connections regularly.
• Keep electrical terminals secure.
• Clean solar panels regularly for maximum energy production.
• Inspect water-level sensors periodically.
• Maintain correct DC polarity during servicing.
• Use qualified technical support for electrical faults.

Do’s & Don’ts

Do’s

• Use a correctly matched 800W DC pump.
• Verify PV voltage before connecting the array.
• Observe correct positive and negative polarity.
• Use correctly sized DC cables.
• Install appropriate electrical protection.
• Keep the controller dry and ventilated.

Don’ts

• Do not connect a pump exceeding the controller rating.
• Do not exceed the specified PV input voltage.
• Do not reverse solar-panel polarity.
• Do not connect AC power unless specifically permitted by the manufacturer.
• Do not operate with loose electrical connections.
• Do not expose the controller directly to rain or water.

Compatibility

The Doyin DYS-90 can be integrated with appropriately matched:

• 800W DC solar water pumps
• Doyin DC borehole pumps
• Solar PV panels
• Borehole water-level sensors
• Storage-tank level sensors
• Float switches
• DC isolators and protection devices
• Water storage systems
• Irrigation systems

Pump voltage and PV configuration must be confirmed before installation.

Performance / Operating Mode

Water flow and pumping head are determined by the connected pump model, available solar energy, borehole depth, pipework and installation conditions.

Mini FAQ

1. What pump size is suitable for the DYS-90?
The controller is intended for a correctly matched 800W DC solar pump. Voltage and current compatibility must also be confirmed.

2. Is the DYS-90 an AC/DC hybrid controller?
No. The DYS-90 is specified as a DC solar pump controller, unlike Doyin AD-series hybrid controllers.

3. Can it automatically fill a water tank?
Yes, where the system is correctly configured with compatible water-level sensing equipment.

4. Can I use it for irrigation?
Yes. When paired with a suitable 800W pump, it can be used for farm irrigation, livestock watering and general water transfer.

5. Does Macire provide delivery and technical support?
Yes. Macire provides technical guidance and can arrange delivery across Kenya.
