According to Clenergy, the latest announcement follows positive reports and feedback from its use at the solar farm, in Kanegasaki, where the box has been connected to a Clenergy SolarTerrace III ground-mounted system. The Sino-Australian company claims that the box is designed to be adaptable to changing requirements and that software for integrating the box into a system and monitoring performance, is sourced from local partners.

When combined with software provided by local partners, the box provides real-time monitoring and power generation reports. The SJB can transmit as well as gather data. Other features include lightning protection and failure warnings. The company claims the SJB is weather proof and secure. The product is in the process of being assessed for TÜV accreditation.

The Japanese solar power market, traditionally considered a difficult region for foreign manufacturers to enter, has seen companies such as CNPV and Jinko Solar gain Japan Electrical Safety & Environmental Technology Laboratories (JET) accreditation for their PV modules in recent weeks. Clenergy claimed the company is “certain” about SJB’s market potential in Japan.

Clenergy’s String Joint Box product manager Hisashi Matika, said: “Our combination of the Clenergy SJB hardware and the local partner software, delivers cutting edge real-time monitoring service and accurate PV generation reports to our clients.”
