Product Description and Features
500V PV Combiner Box with Panel-Mount Connectors
The 500V DC PV Combiner Box 1-In 1-Out provides a compact connection and protection solution for one photovoltaic string. Its panel-mount connector design supports convenient plug-in wiring between the solar array and downstream DC equipment.
The enclosure integrates a photovoltaic fuse, DC surge protective device and DC circuit breaker. The fuse protects the circuit against overcurrent, while the surge protective device helps limit transient overvoltage caused by lightning-induced surges or switching events.
The DC circuit breaker provides circuit isolation for installation, inspection and maintenance. Panel-mounted input and output connectors help reduce internal field wiring and allow compatible PV cables to be connected without opening the enclosure.
This 500V DC PV combiner box is suitable for residential photovoltaic systems, small off-grid installations, RV solar applications and other low-voltage DC projects. Its compact structure makes it particularly useful where installation space is limited.
SOLKV provides OEM and ODM services, including customized protective component ratings, connectors, product labels, logos, packaging and internal configurations.

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.
What is the difference between a 3-in-1-out and a 3-in-3-out box?
A 3-in-1-out combiner box combines three PV strings into one output. A 3-in-3-out protection box keeps the three circuits independent and provides a corresponding output for each input.
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.
Can these products be installed outdoors?
Outdoor suitability depends on the confirmed enclosure protection rating, UV resistance, cable-entry method and operating temperature. These specifications should be verified before publishing an IP rating or outdoor-use claim.
