WRDZ Solar System PV Waterproof Combiner Box for 4 Strings 1 in Solar Panel

Product Overview

Description

 

• 
  

  PV Combiner For a large-scale grid-connected PV system, it is a general practice to install a DC combining device in between the PV modules and inverters for the sake of minimizing the cable distance between them, facilitating maintenance and improving reliability.

  
  


• 
  

  With many years of PV grid-connected system design experience, our PVB PV array combiner box series is specially-designed for meeting the need of high performance and high reliability of PV systems.

  
  


• 
  

  In combining with our Solar Access inverters, Sandi PVB provides a turnkey solution for PV power plant systems.

  
  


• 
  

  By using PV array combiner box, according to the input voltage of the inverter, Clients can connect a fixed number of similar PV modules to form a PV array.

  
  


• 
  

  Then different strings of PV array can be converged into the PV array string box.

  
  


• 
  

  After that, together with lightning arresters and circuit breakers, it is connecting to the inverter to reduce the system installation time and increase the system safety.
