Akash Hirpara CSA C22.2 is the Canadian Standards Association's series of product safety standards for electrical equipment, referenced by the Canadian Electrical Code (CSA C22.1). For solar, CSA C22.2 No. 61730 covers PV module safety and C22.2 No. 107.1 covers power conversion equipment such as inverters. Canadian inspectors expect this certification.
Key Takeaways
- CSA C22.2 = Canadian electrical safety standard series.
- Equivalent in scope to UL listings used in the US.
- Joint UL/CSA listings are common in North America, so many products carry both marks.
- Required for solar equipment installed in Canada; not a substitute for a US UL listing on a US project.
What CSA C22.2 Covers
CSA C22.2 is not a single document but a series of standards published by the Canadian Standards Association, each addressing a specific category of electrical equipment, inverters, PV modules, junction boxes, connectors, and racking hardware among them.
A product is “CSA C22.2 listed” when an accredited testing lab has confirmed it meets the relevant part of that series for construction, insulation, grounding, and fault protection. In practice, the standard plays the same role in Canada that UL listings play in the US: it’s the baseline evidence an AHJ or utility asks for before approving equipment for interconnection.
Why Joint UL/CSA Listings Matter
Because the underlying safety requirements in the US and Canadian standards overlap heavily, testing labs frequently run a single evaluation and issue a joint UL/CSA listing report. That’s why it’s common to see both a UL number and a CSA C22.2 designation printed on the same inverter or module datasheet.
For an engineer specifying equipment on a cross-border portfolio, that joint mark is the quickest way to confirm a product is eligible for permitting in either country without needing a second round of certification.

If you’re comparing electrical safety standards across module and inverter equipment more broadly, QBITS Energy’s guide to solar inverter certification standards covers the IEC-based listings used outside North America, and its IEC 62109 entry is a useful point of comparison for the inverter safety requirements CSA C22.2 and UL 1741 both address.
For the US equivalents, see UL 1741 for inverters and UL 61730 for modules. The module safety standards comparison sets the North American and IEC listings side by side.
