Thyristor switching module can achieve seamless switching, switching time is less than 10ms; Contactor switching module time is longer, there may be adhesion in the switching process. From 2020, the switching modules of PCs products will be upgraded to thyristor switching modules.
PCS above 500kW are not equipped with transformers, because in most cases, the power grid will have high-voltage transformers.
Under 500kW, compared with the equipment without power frequency isolation transformer, THDu and THDi are smaller, output characteristics are stable, load adaptability is stronger, and power quality is higher, which is more suitable for industrial applications.
Reset the time and date, power off 10 minutes and then start to see if the clock can be real-time timing.
The output power in the grid parameters is set to 0%. If the grid connected power needs to be reduced, this parameter can be modified to the required percentage.
No, the photovoltaic input can only be used to charge the battery and cannot generate electricity to load.
No, there is no internal outpuit terminal for wake up generator.
GD5000 comes standard with built-in PID regulator, which can realize closed-loop control.
The full range of medium voltage GD1000/GD2000/GD3000 products can provide two-quadrant or four-quadrant products.
GD5000/3300V products are designed with multi-level power units connected in series. GD3000/3300V adopts a three-level topology design scheme, mainly comparing and replacing ABB ACS1000 series and Siemens GM150 series.
