As one of the earliest companies enter into the field of new energy, Topband Automation is specialized in the R&D and manufacture of the system and equipments of electrical power and solar PV energy. Based on independent research and self-innovation, Topband Automation has its own independent intellectual property of products. The PowerSA series of PV monitoring system and equipments have become the first brand in this field. At present, the PowerSA-SUN series products of PV array monitor, data logger, weather monitor, combiner box, AC/DC power distribution cabinet, SCADA system and prevent reflux system, are widely used in different scaled PV power system and projects.


The PowerSA-SV lightning protection combiner box combines up to 24 PV strings DC input into one output, each equipped with fuses, and the output is equipped with circuit breaker and lightning protection. For large-scale PV grid-connected power generation systems, in order to reduce the connection lines between PV modules and inverters, facilitate installation, maintenance and improve reliability, it is necessary to add a DC converging device-PV combiner box between PV modules and inverters to provide lightning, short circuit and grounding protection. The combiner box is divided into two types, intelligent and non-intelligent.
The smart lightning protection combiner box is equipped with a monitoring unit, which can monitor the input current of each PV string, summarize the output voltage, detect the temperature, the status of the lightning protection device and the circuit breaker in the box.
The internal structure of the device is simple and clear, with neat and reasonable wiring. High reliability and easy maintenance. Outdoor wall-mounted installation, which can adapt to various harsh environments. In addition to related core components, others can be customized according to user requirements.
This product is used specially for 1500V system PV power station and it is wall-mounted.

All above is standard configuration, can adjust the configuration as per your demand.

In enquiring phase, we have Professional Structure engineer getting to know the technical demand from clients, then will tailor-made the structure design, clear array for the internal components, meanwhile, ensure the electricity saftey distance.


TOPBAND has established a complet test and verification laboratory system. Our own laboratory capability has been approved by CNAS National Laboratory, CIF laboratory acceditation of IECEE, and TMP Laboratory accreditation by DEKEA. Can be tested and verifed in all aspects of design, development, manufacturing at any stages: Electromagnetic compnatibility, safety, reliablity, environmental protection. etc.
