Hybrid Solar Submersible System Introduction 
Solar panels generate DC power during daylight, then,the solar DC pump controller adjusts and sends the power to DC pump to lift water to the storage tank or moves water for remote small farm irrigation,livestock, or domestic use.

Features of the Solar DC Pump Controller
- Hybrid type solar pump controller, using solar on day time and using AC input from grid utility or disel generator at night.
- Waterproof Rating: IP65 – suitable for outdoor installation and protection against dust and rainning .
- Wide Operating Voltage Range: Compatible with a broad range of solar panel outputs.
- Ambient Temperature Range: Operates reliably in temperatures from -15°C to 60°C.
- MPPT Technology: Maximizes solar power utilization by tracking the maximum power point in real-time.
- LED Display: Shows real-time operating conditions including power, voltage, current, and pump speed.
- Adaptive Speed Control: Automatically adjusts pump speed based on sunlight intensity,manual speed adjustment is also available.
- Automatic Operation:Supports automatic startup and shutdown without the need for on-site supervision.
- Soft Start Function: Eliminates sudden inrush currents to protect the pump motor during startup,extend lifetime of motor.
- Comprehensive Protection Features:
- Over-voltage protection  - Under-voltage protection   - Over-current protection  - Phase loss protection   - Short circuit protection  - Dry-run (water shortage) protection  - Over-temperature protection
Advantages of Solar DC Pump:
-High-Efficiency Motor:Equipped with a permanent magnet higher efficiency DC brushless motor, reduced energy consumption.-Durable Rotor
Shaft:Constructed entirely from 304 stainless steel, the rotor shaft eliminates the risk of breakage and enhances durability.

-Corrosion-Resistant Components:Features brass and stainless steel for the outlet, connector, and oil cylinder, offering superior corrosion
  resistance in harsh environments.
-Long-Lasting Bearings:Fitted with high-durability NSK bearings for extended operational life.
-Enhanced Bearing Structure:Double-bearing design at the rotor base using angular contact bearings to withstand greater axial loads.
-Reliable Mechanical Seal:Utilizes a silicon carbide-impregnated graphite seal for long service life and dependable sealing performance.
-High-Temperature Copper Windings:Uses 180°C heat-resistant copper wire with insulation class F for enhanced thermal stability.
-Precision Stator and Rotor:Made from cold-rolled 600-grade silicon steel sheets for improved magnetic performance and efficiency.
-High-Grade Magnet:Incorporates 40SH NdFeB magnets capable of withstanding temperatures up to 150°C.
-Stainless Steel Pump Shaft:Built with 304 stainless steel for high strength and corrosion resistance.
