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
• Suitable for use in AC 50Hz, rated AC230V/400V circuits
• Green light during normal operation, red light or two lights off for fault problems
• As the overload and short circuit protection of the line
• Indirect lightning and direct lightning effects or other transient overvoltage surge protection
• Reliable decoupling for suddenly applied or slowly rising AC sine
