Type Selection Table
Type selection instructions:
1. Please read the product instructions carefully, choose the type according to the function and power you need, and avoid the damage caused by wrong wiring.

2. This frequency converter can not drive other load types except inductive load such as motor . Please pay special attention to it when purchasing.

3. The total input power of solar DC should be greater than that of photovoltaic converter, and the power of photovoltaic converter should be greater than or equal to the total load power driven by it.

4. The optimum range of DC input voltage can refer to the best input value in the selection table to ensure the most efficient operation of frequency converter and motor. Changing the DC input voltage can be achieved by changing the series and parallel connection of solar panels.

Supplementary Note:

The main circuit terminals R S T are three-phase AC input (220V is R T), P+ and N- are PV DC input; when input AC, DC must be disconnected and cannot be powered at the same time.
WHY DO YOU CHOOSE US?
I. Products and Technology
• Built-in MPPT controller：
MPPT: full name “Maximum Power Point Tracking”. It can detect the generation voltage of solar panels in real time, and track the maximum voltage and current value (VI), so that the system can output the driving load with the maximum power and apply it to solar photovoltaic system to coordinate the work between solar panels and loads. It’s the brain of photovoltaic systems.
• Supporting Wide Voltage Input;
A, 220V photovoltaic converter corresponding input voltage below 280V will jump low-voltage alarm shutdown, 380V above automatically suppress voltage rise, avoid overlooking overvoltage shutdown;
B, 380V photovoltaic converter corresponding input voltage below 380V will jump low-voltage alarm shutdown, 650V above automatically suppress voltage rise, avoid overlooking overvoltage shutdown.
• Support unattended automatic start and stop.
In the morning, when the illumination intensity rises to a certain extent, the input voltage reaches about 380 V (220 V photovoltaic converter reaches about 280 V), and the photovoltaic converter automatically starts driving load operation without manual operation.
In the evening, when the illumination intensity decreases to a certain extent, the input voltage drops to about 380 V (220 V photovoltaic converter reaches about 280 V), and the photovoltaic converter automatically stops driving the load without manual operation.
