Product Description and Features
Compact 1000V PV Combiner Box
The 1000V DC PV Combiner Box 1-In 1-Out is designed for the connection and protection of a single photovoltaic string. Installed between the solar modules and the inverter, it combines essential DC protection components within one compact enclosure.
The input circuit can be equipped with a photovoltaic fuse to protect against overcurrent and reverse-current conditions. The built-in DC surge protective device helps limit transient overvoltage and reduce the risk of damage to the inverter and other photovoltaic equipment.
A DC circuit breaker provides circuit isolation and enables the PV string to be disconnected during installation, inspection or maintenance. The internal component layout is clear and accessible, helping installers complete wiring and servicing efficiently.
This 1-in-1-out PV combiner box is suitable for residential rooftop installations, off-grid solar systems, small commercial PV arrays and other applications requiring a compact 1000V DC protection and connection solution.
Fuse ratings, circuit breaker ratings, connector types, labels and packaging can be customized for OEM customers, distributors and photovoltaic project contractors.
