How CEC Efficiency Ratings Make or Break Your Solar Investment

When an inverter meets CEC requirements, it means the device has been thoroughly tested and proven to convert DC power from solar panels to usable AC power with minimal energy loss.

The Efficiency of Solar Inverters

You may encounter the following terms referring to efficiency when looking for an inverter: peak efficiency, Euro efficiency and CEC efficiency. The difference between these is explained below.
