Product Description

Product Description

MOREDAY PV combiner boxes are designed to consolidate the DC input from 4 to 36 PV strings into a single output. Each input channel is equipped with a fuse, while the output side includes both surge protection (SPD) and a circuit breaker. This greatly simplifies the DC wiring between the solar modules, distribution cabinet, and inverter.

The combiner box provides multiple layers of protection, including lightning protection, short-circuit protection, and reliable grounding. It is available in two types: intelligent and non-intelligent versions.

The intelligent PV combiner box is equipped with a monitoring unit that enables real-time monitoring of:

Input current for each string
Internal temperature
Surge protection status
Circuit breaker status
Output voltage summary
This solution enhances system safety, reduces installation complexity, and improves overall maintenance efficiency for both on-grid and off-grid solar systems.

The design and configuration strictly follow the "Technical Specification for Photovoltaic Junction Equipment" (CGC/GF 037:2014) standard.

We provide users with safe, efficient, aesthetically designed, and practical photovoltaic system products.

The product features an outdoor wall-mounted design, making it suitable for harsh environmental conditions.

While the core components are standardized, other configurations can be customized according to user requirements.
