How to choose suitable PV Accessories?
PV Accessories are auxiliary components in photovoltaic power generation systems, which are of great significance to ensure the efficient operation, stability and safety of the system. Common photovol
• Quickly dissipate heat and reduce the service temperature
• Plug-in clips, Easy module replacement
• Flash Barrier, Prevent arc propagation in current impact
• Use a suitable electrical insulator to keep a 10mm min.safety distance from
the PV-SPD and other grounfed parts in the housing
• The green and red visual indicator flags show the module protective status
(green = good, red = replace)
• Features visual indication and optional remote contact signaling
(floating changeover contact)
• Feature a combined disconnection
• Short-circuiting (shunting) device with safe electrical isolation to Prevent fire damage due to DC arcs.
