Product Description and Features
1000V DC PV Combiner Box for Three Solar Strings
The 1000V DC PV Combiner Box 3-In 1-Out is designed to combine three photovoltaic string circuits into one protected DC output. It provides a centralized connection point between the PV array and the solar inverter, reducing field wiring and simplifying system installation.
Each input circuit can be equipped with a dedicated photovoltaic fuse to provide overcurrent and reverse-current protection. The integrated DC surge protective device helps protect downstream equipment against transient overvoltage caused by lightning-induced surges or switching events.
A DC circuit breaker on the output side allows the combined circuit to be safely disconnected during commissioning, inspection or maintenance. Clearly arranged internal components make wiring, troubleshooting and component replacement more convenient.
The insulating enclosure helps protect the internal electrical components from dust, moisture and accidental contact. This 1000V DC PV combiner box is suitable for residential solar installations, commercial rooftop systems, off-grid PV projects and other applications requiring three-string combination.
SOLKV supports customized fuse ratings, circuit breaker ratings, connector types, labels, logos and packaging for distributors, installers and photovoltaic system integrators.

FAQ
What information is required when selecting a PV combiner or protection box?
Please provide the maximum system voltage, number of PV string inputs and outputs, maximum current per string, required surge protection level, connector type and installation environment.
Can the fuse and circuit breaker ratings be customized?
Yes. Fuse, breaker, surge protector and connector ratings can be configured according to the PV string current, inverter requirements and project specifications.
Are OEM and private-label services available?
Yes. SOLKV can provide customized logos, labels, packaging, connection methods and internal component configurations for distributors and project customers.
What does 3-in-1-out mean?
It means the combiner box receives three separate PV string inputs and combines them into one DC output connected to the inverter.
