Solar PV systems and EV charging stations are typical power-electronics-intensive applications. PV inverters, rectifiers, charging modules, and high-frequency switching devices may cause harmonic distortion, voltage fluctuation, reactive power reverse flow, abnormal power factor, and three-phase imbalance.
CNBYG provides SVG, APF, and modular power quality cabinet solutions to improve grid connection stability, reduce power losses, and enhance the reliability of renewable energy and EV charging infrastructure.
Solar PV output changes with sunlight, weather conditions, and grid operation. EV charging stations also experience fast load changes due to different charging power levels and vehicle connection patterns. When PV systems and high-power EV chargers are connected to the same distribution network, power quality problems may become more complex.
CNBYG’s SVG Static Var Generator provides bidirectional reactive power compensation to stabilize voltage and power factor at the grid connection point. CNBYG’s APF Active Power Filter mitigates harmonics generated by PV inverters, rectifiers, and EV charging modules.
The solution helps renewable energy and charging projects achieve safer, more stable, and more efficient operation.
PV inverters and EV chargers generate harmonic currents.
Fast-changing charging loads cause voltage fluctuation.
Distributed PV systems may cause reactive power reverse flow.
Uneven charger distribution may create three-phase imbalance.
Harmonics increase transformer, cable, and switchgear temperature.
Poor power quality may affect grid compliance and project acceptance.
Charging infrastructure requires reliable long-term operation with minimal maintenance.
CNBYG combines SVG dynamic reactive power compensation, APF harmonic mitigation, and intelligent monitoring for solar PV and EV charging applications.
The SVG provides fast bidirectional reactive power control, helping stabilize voltage and improve power factor at the grid connection point. It can respond quickly to power changes caused by PV output fluctuation and EV charging load variation.
The APF filters harmonic currents generated by inverters, rectifiers, and charging modules. It reduces THDi and protects transformers, cables, switchgear, and other electrical assets from overheating and harmonic stress.
CNBYG can provide wall-mounted, rack-mounted, or cabinet-type solutions according to site capacity, installation space, and project requirements.
