Pump Material

• Maintenance-free unattended operation solar water pump system with water level sensor.
• Multistage centrifugal impeller anti-lock & anti-sand pump lift not just clean water.
• Power frequency system & centrifugal pump, reliability performance even harsh conditions.
• Special design low speed starting motor for the solar-powered system, high energy efficiency.

Outer MPPT Controller

• Waterproof grade: IP65
• Ambient temperature: -15C-60C
• MPPT function, the solar power utilization rate is higher.
• Automatic charging function: Guarantee the pump normally working, meanwhile charge the battery; And when there
  is no sunshine, the battery can make the pump continuously working.
• LED displays the power, voltage, current, speed, etc working conditions.
• Frequency conversion function: It can automatically run with frequency conversion according to the solar power, and
  the user also can change the speed of the pump manually.
• Automatically start and stop working.
• Waterproof and leak-proof: Double seal effect.
• Soft start: No impulse current, protect the pump motor.
• High voltage/Low voltage/Over- current/High temperature protection

Benefits

• Long life expectancy: DC brushless motor for a long lifetime.
• Fast and simple installation: Small size and portable, outer MPPT controller, easy for carrying and installation.
• Designed for use in remote and harsh conditions: It’s workable for off-grid areas with solar panel power.
• High efficiency: Special design low speed starting motor for the solar-powered system, high energy efficiency.
