Enphase Combiner Box Substitute
I can't find an Envoy Combiner Box anywhere. Is there a way to build a code-compliant Enphase combiner box?
This question has been asked often by installers during this market shortage. Enphase provided the following helpful advice to make your own Q Combiner:
To make your own Qcombiner box…Use an off-the-shelf subpanel with the required ampacity and circuit capacity for the job.
- Buy an IQ Envoy standalone and wire it off a 2-pole 10A breaker in the subpanel, along with a neutral connection.
- Install/mount the Envoy in an NEMA 3R non-metallic enclosure adjacent to the subpanel, such as the Arlington EB1111 or EB1212.
- Cellular, wi-fi or hardwired options can be used for providing internet, and production and consumption CT's would be wired (if needed) as shown on page 3 of the IQ Envoy quick install guide.
- Page 12 of this guide covers some details: https://enphase.com/sites/default/files/downloads/support/TechBrief-Pla…
Good luck with your project!
I added a photo of one of the enclosures noted, thanks!
