Product Details and Features:
1. Power from 220V (0.75 – 75KW) , 380V (0.75 – 160KW)
2. DC/AC Input Compatible, can support DC and AC Input at same time
3. With a variety of protection functions to improve the reliability of the system work.
Specially designed for water supply users, adaptable to various occasions application, easy to operate.
4. Adopt advanced MPPT technology to give full play to the power generation efficiency of the solar cell array.
5. It prevents the pump from pumping empty when the water source is dry.
6. Automatic dormancy when the light is weak (e.g., sunset) and withdrawal from dormancy when the light is strong (e.g., sunrise).
7. Automatic dormancy at high water level of the reservoir and automatic restart at low water level to realize automatic water level control.
8. Support optional LCD display and GPRS module.
Conditions for full water detection to take effect:
1. Any DI terminal set to No. 60 function receives the input switch closing signal. For example, after P06.03
is set to 60, DI3 closes.
2. The analog input is greater than the detection value, for example: set P47.18 = 1, P47.19 = 50%, then the
AI1 input is greater than 5V or 10mA
3. After the condition 1 or 2 is met, continue to set the time at P47.20 and the system will report A.FULL
Full water recovery conditions:
4. The system enters the full water detection stage and displays A.FULL
5. When both conditions 1 and 2 are not met and the maintenance time is greater than the time set in
P47.21, the system resumes.
Accessories:
1. GPRS (support 2g/3g/4g internet)
It supplies water volume monitoring and operation of inverter from anywhere at anytim
It’s convenient to visit real time and historical data via web or Android APP anytime and anywhere.
This easy-to-use platform makes monitoring of solar pump systems simple and convenient,
far reducing operate time and monitoring costs as well.
2. LCD keypad
Standard inverter are with LED keypad,LCD keypad is optional.
LCD keypad can monitor 4 parameters at the same time. LED keypad show one parameter only.
LCD keypad with detailed parameter explain,no need use user manual ,more user friendly.
LCD keypad with copy and update and download function.widely used for government projects and big farms.
3. Output Reactor
When the distance between inverter and pump is more than 70m, you need use reactor to protect this system.
