Check first
- When exactly does it trip? Outage-linked → neutral–earth behaviour in backup. Dewy mornings → PV insulation. Under one appliance → that appliance. Random → measure, don’t guess.
- Which device trips — the main RCD, a sub-circuit RCD, or an MCB? An MCB is overcurrent, not leakage — different flow (Backup Not Working).
- Record the site’s N–E voltage in both grid and backup states — Kent service will ask for it. [KNB-VAL-04]
Escalate when
- Outage-linked tripping persists on a site wired exactly per the platform AC pages — send the N–E readings, RCD nameplate photo and trip log. [KNB-VAL-04]
- Leakage-class faults persist after the strings insulation-test clean and connectors are verified dry/sound.
- Anyone proposes running without the RCD “for now” — that is a stop-work, not a workaround.
Escalate to Kent New Energy service only — through your registered Kent partner channel or the Kent service desk details on your work order. Do not contact any third-party or component-manufacturer support line for a Kent-branded system: tickets outside the Kent channel are not tracked, not covered, and can void warranty handling.
