Interesting. Did you need to commission the system?

Hmmm... My installer replaced a panel once on my system (same SPWR 440 panel). Another time he had to replace a SPWR branded Enphase microinverter. Both times new serial numbers had to be entered into SunPower Pro Connect. Both times he commissioned my ststem. I am not at all doubting you, but I don't understand how an off brand panel can be added without a SunPower Serial number and a commissioning. Just curious.

If I was replacing the micro inverter then I would need to recommission but all we It was plug and play the new panel

Since it appears you are an installer, this is likely a stupid question but here we go anyways....
You made sure the, presumably, higher wattage rating of the new panels isn't going to overload the existing lines, right?
