My solar panels aren't feeding back — installer, inverter, or supplier?

DIRECT ANSWER

Three links: panels → inverter → meter/supplier. We give the 4-step elimination diagnosis + claim route.

Diagnostic order:

  1. Check inverter display or app. Error code? Photo, contact installer (2-5 year warranty).
  2. Check smart-meter P1 port or readingfeed-in counting up? If no → inverter or wiring; if yes → supplier billing issue.
  3. Check supplier portalis feed-in shown as consumed? Mismatch with meter = admin error, request revision.
  4. No fix → written complaint to installer (within warranty) or supplier (billing error) with 14-day deadline + Geschillencommissie announcement. For installer claims: keep installation agreement + warranty terms ready. For inverters: manufacturer has own RMA (Goodwe, SolarEdge, Enphase).
