Possible Causes
Damaged or improperly installed gasket, Cracked enclosure, Cable entry not sealed, Mounting orientation not per spec
How to Fix / Troubleshooting
Shock hazard: Do not use the charger if water is inside the enclosure. Turn OFF the breaker immediately.
- Inspect exterior: Look for cracks, gaps around cable entries, or missing plugs in unused knockouts.
- Check mounting: Verify the charger is mounted vertically and per Enphase instructions so water cannot pool on top or enter vents.
- Drying: Do not open the unit yourself if it voids warranty. Allow the exterior to dry and keep power OFF.
- Professional service: A technician should open the enclosure, dry internal components, assess for corrosion, replace any damaged boards, and restore or replace gaskets and seals.
- Prevent recurrence: Improve shelter (e.g., awning) if the charger is exposed to direct rain or sprinklers.
