CERTIFICATIONS & COMPLIANCE

For every applicable requirement,
find the matching product boundary and manufacturing evidence

Compliance is not a certificate added at project end—it is an engineering chain maintained from product boundary, design input, manufacturing control, and test validation through factory evidence and site applicability. Every requirement must answer: where it applies, who controls it, how it is verified, and where the evidence lives.

The “certified” in a single market does not automatically mean that any project can be used directly, and the project still needs to be reconfirmed in combination with on-site conditions, grid specifications and AHJ requirements.
