HEDY Dc-ac Inverter Single Phase to Three Phase 2.2KW 3.7KW 5.5KW 7.5KW Solar Pump Inverter

HEDY Solar inverter MPPT VFD converter, Solar pump inverter in Solar panel / wind system [China manufacturer]

HEDY Solar frequency inverter HD300 series

Specifications

Using solar energy for water pumping, solar panel to inverter to motor.
green energy, high efficiency.

HD300 Variable Frequency SOLAR Drive is positioned in environmental-friendly and economical PV market, the product is applicable to PV pumping system, replaces water storage with electric storage and needs no battery modules. The direct current generated by solar modules is input to the inverter and then converted into the alternating current to drive various pumps directly. Additionally, the output frequency is adjustable in real time according to sunlight intensity change.
Specification:
200 -400VDC input, 220VAC output, 0.75 to 3.7kw
450-780VDC input, 380VAC output, 0.75 to 55kw.

Descriptions and Features:
1 Internal diagnostics will tolerate a lower input voltage
2Whenever possible, the controller attempts to regulate the pump load in a manner that optimizes for maximum power transfer from the solar array.
3The drive manually switches to AC backup power( when available) if the DC primary source is unable to support pump operation
4TI DSP technology and Infineon PIM design, high quality.
5MPPT function is available
An easy to interface is provided to enhance configurability and enable remote system monitors
6A four-digit seven-segment display provides a detailed indication of systems status.
7Two line display keypad is options
8Built in RS485 ports through 7.5kw, laptop software control is available

Protection features
Electronic monitoring gives the controller the capability to monitor the system and automatically shut down in the even of: Dry run conditions- with smart pump monitoring, High voltage surge, Low input voltage, Open motor circuit, Short circuit, Over heat, Earth fault, Phase missing…

2, Dry protection :
If no water in the ground, the water pump will stop working automaticly and when the water comes, starts to working automaticly.

3, Automatic working:
When the sunshine not good then pumps slow down automatically and when sun become good then go on working.

4, Save cost/directly connect solar panel:
Solar panle connects solar inverter directly and to the pump. Also can control the water level in the tank. No enough water in the tank working fast, enough water will stop working automaticly. (how many water you need, you can set the parameters)

5, Speed & frequency control, No need battery:
0-320hz output by Vector control/0-3200hz output by VF control. No need battery in system.
