Photovoltaic Controller

This photovoltaic controller is specifically designed for photovoltaic (PV) integration into 400V power grids.It  automatically manages and regulates the system's reactive power compensation. It is specifically optimized to overcome the limitations of conventional controllers, effectively resolving issues including inaccurate system power factor display and switching anomalies arising from confusing control logic .

 

 

Equipped with a large-screen LCD display, this photovoltaic controller automatically generates various alarm events, supports audio reminders, and provides timely feedback on equipment operation abnormalities.All models come standard with temperature regulation control, eliminating the need for an extra capacitor temperature controller and simplifying equipment configuration.

 

The DC voltage output controller features built-in control signal short-circuit protection. In the event of a short circuit, it triggers an immediate alarm and disables all control signal outputs to ensure equipment safety. All control parameters are password-protected to prevent malfunctions caused by unauthorized modifications by non-professionals.

 

This photovoltaic controller features harmonic detection and protection capabilities, safeguarding both the equipment and the power grid against harmonic interference.

 

One master unit can connect up to 3 slave units, supporting a maximum of 96 output channels to meet the requirements of PV systems of various scales.It supports RS485 and MODBUS‑RTU, features automatic polarity detection for AB lines, and enables remote control, status monitoring and parameter setting to enhance operation and maintenance efficiency.

 

 

 

 

 

 

Note

For active output type control terminals, a single loop is permitted to output no more than 20mA, provided the total output current does not exceed the total number of output loops × 8mA.

For example, a controller with 24 output loops allows a total output current of 24 × 8 = 192mA.If only 10 loops are used, each loop is allowed to output up to 192 / 10 = 19.2mA.
