Acquisition of data for individual certification of solar power and storage battery power conditioners (PCS).
Acquisition of data for individual certification of solar power and power conditioners (PCS) for storage batteries.
By conducting a simulated interconnection test 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 a part of the certification system for low-voltage interconnection protection devices conducted by JET (General Incorporated Foundation, Electrical Safety Environment Research Institute), which allows for the acquisition of equivalent data through certain tests. 【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 measurement circuits 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 evaluations of devices can be conducted for certification of JET interconnection protection devices. 【Location of Testing Facilities】 - Maebashi City, Gunma Prefecture *Please feel free to contact us through our company website.
