Grid Connectivity Testing

Evaluation of Grid Connectivity Protection Devices

The use of renewable energy has risen in the last years and power distribution networks are being upgraded to smart grid: With the advancement of these technologies, the safety of grid connection to power generation and storage facilities will be more and more important.

TÜV Rheinland Japan provides performance testing for grid connectivity protection in distributed generation devices such as solar power generation or fuel cells. Our test facilities can handle grid connectivity tests with a maximum output of up to 50kW; evaluation and certification of devices under 50kW is possible. Long years of experience in the evaluation of IEC standards support TÜV Rheinland customers TÜV Rheinland can evaluate your device according to Japanese as well as international grid connectivity regulations.
