Acquisition of data for individual certification of solar power and power conditioners (PCS) for storage batteries.

last updated：Nov 28, 2024

By conducting simulated interconnection tests in accordance with the certification tests for JET system interconnection protection devices, data can be obtained that will assist in discussions for individual certification.

This service is capable of obtaining equivalent data for certain tests related to the low-voltage system interconnection protection device certification system conducted by JET (General Incorporated Foundation, Electrical Safety Environment Research Institute). 【Target Equipment】 - Single-phase PCS for residential storage systems and solar power generation systems 【Features of the Testing Equipment】 - Easy load adjustment using a resistance load device manufactured by our company - Customization of the measurement circuit is possible to obtain the necessary data 【Benefits of This Testing Equipment】 - Data can be obtained that is useful for discussions on individual certification. - Performance evaluation of the device can be conducted for certification of JET interconnection protection devices. 【Location of the Testing Facility】 - Maebashi City, Gunma Prefecture *Please feel free to contact us through our company website.
