Mr Bill,

Enphase microinverters are not compatible with all solar panels. You should check compatibility using the Enphase compatibility checker: https://enphase.com/installers/microinverters/calculator Hopefully your Canadian Solar pv panels are compatible but I have yet to a PV panel by Canadian Solar that will work with Enphase microinverters. I made the mistake of personally purchasing Canadian Solar panels before without checking and luckily I caught the shipper before they were shipped and I returned them without a fee. Good luck and keep up updated.
