Photovoltaic combiner boxes are mainly used in residential distributed grid-connected photovoltaic power generation systems and small-scale industrial and commercial photovoltaic power generation systems. They are connected in series between the grid-connected inverter and the power grid. The products feature a series of protections including anti-islanding protection, overvoltage protection, undervoltage protection, grid overvoltage protection, input overcurrent protection, and grid isolation. Accurate metering, transmission, and intelligent operation control are essential products in residential grid-connected power generation systems, meeting relevant certification standards such as ETL, UL, CE, CSA, and IEC.

Key Features: Reserved installation space for the meter and data collector; Meter viewing window with lead seal (anti-theft); Integrated design concept, with complete isolation between the power distribution and metering sections to reduce electromagnetic interference; Multiple self-resetting over/undervoltage protectors and photovoltaic-specific closing circuit breakers are available to meet the usage needs and acceptance standards of different areas; The box cover requires a special key to open, enabling professional management; Plastic and stainless steel enclosures are available; Outdoor installation ensures safer use; Customization for special requirements and functions is supported.
