What You May Also Need
Usually required
- Enphase Q Cable / IQ Cable with the .24 × .38 in (6.1 × 9.7 mm) profile Heyco lists, entering an enclosure with a matching 3/4" clearance or NPT hub.
May be required
- Q-CLIP-100: Manage cable slack outside the enclosure.
Optional upgrades
- M3234GBR-SM: Different gland — 5-hole PV cable, not Q Cable.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Not interchangeable with M3234GBR-SM without checking cable OD and hole count.
- Match cable OD and enclosure opening before ordering.
