Product Description

PRODUCT INTRODUCTION
Features

1. Single-phase, three-phase selection function: Can be chosen to control single-phase or three-phase motor.
2. Power on restart: Running automatically when power on.
3. Through adopting advanced MPPT technology, this product can make full use of the efficiency of the solar cell array.
4. It can automatically adjust the motor speed and the water flow along with the intensity of sunlight.
5. Automatic sleep when on high-water level and automatic restart when on low-water level to realize automatic control through water level.
6. Can prevent pump from anhydrous idling.
7. It also can enter automatically to sleep mode when the intensity of sunlight is weak (e.g. the sunset.), as well as can exit the sleep mode when the intensity of sunlight is becoming strong (e.g. the sun rise.).
8. Protect itself in trouble and improve the reliability of whole system.

ENVIRONMENTAL REQUIREMENT

1. Environment temperature range: -10ºC~+40ºC. Controller will be derated if

   ambient temperature exceeds 40ºC.

1. Prevent rain drops, moist environment, oil fog, salt erosion, corrosive gas,

   etc.

1. Prevent direct sunlight, keep away from radiation source.
2. Prevent violent vibration or sudden impact.
3. Lower than 1000m installation altitude, it will be derated when the altitude is

   higher than 1000m.
6. Attention
