What is a photovoltaic combiner box

Photovoltaic combiner box is a key device in the photovoltaic power generation system used to collect, distribute and protect the electric energy generated by photovoltaic modules. ‌The role of the photovoltaic combiner box in the photovoltaic system‌ lies not only in the collection and distribution of current, but also in the protection and monitoring of the system. It can significantly improve system reliability, reduce the risk of failure, and facilitate system maintenance and management.

Rating IP65

Our combiner boxes are waterproof, dustproof, and corrosion-proof and can be used uninterrupted for long periods of time in harsh environmental conditions

Photovoltaic solar string current aggregation

We provide multi-string input of up to 24 solar strings, and the maximum current of each string can reach 30A.

Effective isolation

The maximum voltage of the series isolation switch can reach 1500V DC, which can meet the needs of a wide range of photovoltaic power systems.

Lightning protection

The surge LD-40 series we use uses a 6mm shield storm lightning protection chip, which is sensitive, responds quickly, and protects against lightning instantly. Provide lightning protection for your photovoltaic power system.

Overcurrent protection

LQPV-32X with LED indicator light, touchable safety fuse, easy-to-replace fuse, provides over-current protection to ensure stable performance.

Short circuit protection

LQL7 and LQB1 series circuit breakers provide short circuit protection. Prevent damage and accidents.
