No.  A standard grid tied solar PV system will not provide power in the event of a power outage as the Canadian Electrical Code dictates that the system must be disconnected from feeding into the grid in the event of an outage; however you can consider modifying the configuration of the existing grid tied system by adding a battery bank and correspondingly sized inverter/charger and critical loads panel to provide power in the event of an outage. Let us know if you’re seeking more information about adding battery back-up to a critical loads panel, whether you have a grid tied solar PV system or not, and we can assist you with sizing the necessary battery bank to power the critical loads for a certain number of days. Consult an professional for the installation of your solar PV system. Raysolar and it’s Partner network can help make your solar project a reality.
