Supports solar inverter / hybrid inverter up to single-phase 8 [kW] / three-phase 12 [kW]! Various tests in accordance with grid connection regulations can be automatically conducted at our testing facility in Osaka!

Various tests in accordance with the system interconnection regulations can be conducted automatically at our testing facility using the "System Interconnection Automated Testing Software." Additionally, it is possible to create test programs based on your company's optional tests and conduct them automatically. We also support remote output control function testing. Testing without code is possible using our new product, "Test Script Creation Software." Test results are output as Excel files, in addition to detailed display and verification of waveform data on the software screen. You can send us the equipment to be tested, and we can conduct the tests on your behalf. We also accept estimates for building similar testing environments. 【Please use our services if you: 】 ● Do not have a testing environment in-house and cannot conduct operational tests ● Want to confirm the performance of your development products before certification testing ● Want to improve the performance of your development products ● Do not know specific testing methods or evaluation criteria ● Want to confirm the benefits of automated testing ● Lack testing environments or personnel for testing
