Noise filter protects critical networks and PV installations
For years, solar panel installations have caused interference on the C2000 network, the communication system used by all Dutch emergency services. Various reports confirm that PV installations can disrupt the signal range of two way radios and other essential communication equipment. In emergency situations, where every second counts, a poor connection can be life threatening.
A noise filter in the installation is therefore essential to prevent such interference. By actively suppressing disruptive signals, the filter directly contributes to the safety of emergency services and nearby installations.
What causes the interference
Interference is typically caused by:
- Inadequate or missing EMC filtering in the inverter
- Components that do not meet applicable EMC standards
- High frequency conducted emissions via DC cabling
When these factors occur simultaneously, the installation may unintentionally emit high frequency signals. These emissions can disrupt the C2000 network, reduce mobile phone performance or affect radio communications.
The solution: PVbox with integrated noise filter
Conduct offers a reliable solution with the PVbox featuring an integrated EMC EMI filter. Installers place the PVbox between the solar modules and the inverter. Thanks to this strategic position, disruptive emissions are suppressed directly at the source. This protects communication infrastructure and extends the operational life of the PV installation.
Benefits of the PVbox with noise filter
The PVbox provides dedicated filtering per MPPT input of the inverter, ensuring suppression exactly where it is needed.
- Safe: prevents interference on critical networks such as C2000
- Reliable: protects inverters and solar modules against harmful high frequency leakage currents
- Flexible: suitable for all 1000 VDC string inverters including custom applications
- Powerful: standard rated up to 50 ADC at 55 degrees Celsius, higher values available on request
With these properties, the PVbox with EMC filtering is a future proof solution for secure and interference free PV system operation.
