Troubleshooting before you return anything
Most field issues trace back to cable size, crimp quality, sealing or mating compatibility. Check these first.
| Symptom | Likely cause | Action |
|---|---|---|
| Connector runs hot | Undersized cable, incomplete crimp or loose mating | Check cable cross-section, re-crimp with the specified die, confirm the connector is fully latched |
| Water inside the connector | Cable outside the sealed range, damaged seal or incomplete assembly | Replace the seal, verify cable OD, re-assemble and follow the IP67 procedure |
| Connection separates under vibration | Locking clip not engaged or mismatched halves | Confirm mating compatibility, push until the lock clicks, inspect the clip |
| High contact resistance | Corrosion, wrong plating or poor crimp | Clean or replace the contact, verify crimp height and plating |
| Combiner box trips | Fuse or breaker below string current, or SPD at end of life | Check string Isc and inverter input, inspect the SPD indicator, replace with the matched rating |
Send photos and the batch label with the description — it usually shortens the diagnosis to one reply.
Warranty and returns
Standard warranty
Covers manufacturing defects for the warranty period stated in the quotation.
What to send
Photos, batch or label reference, quantity affected and the application conditions.
Assessment
We reply within 8 working hours and confirm replacement or credit after evaluation.
Installation conditions
Assessment follows the installation and operating conditions stated in the datasheet for the model.
If a part fails: three steps
Nothing is decided from a description alone. The batch reference links the claim to the production record.

Assess
We reply within 8 working hours with a cause assessment and the next step.
Resolve
Confirmed defects are replaced or credited; the lot reference is checked against the inspection record.
