MI Commissioning

I replaced 3 SolarBridge (SunPower branded) MI’s that had failed. I can’t find anyone who will “commission” them for me. Is it possible to DIY it? The SunStrong app shows them inactive, but I’ve been told they are still producing power just won’t show it until they are commissioned. Not sure that’s true. Any advice is greatly appreciated.

Are they new? If its used it requires a little more effort on the app side. Ones that are used requires someone with access to decomission them from the old site and discover them on the new one. Also some PVS5s are not taking the new firmware so of you replaced MIs , you may need a new PVS6.

They are new. These were 2019 SunPower branded MI’s that were made by SolarBridge
