PLENTICORE G3

DE Warranty conditions

Current text

labour: In years 1–5 KOSTAL may reimburse an installer exchange allowance as goodwill, using its separately published current rate for the nearest installer; distant-installer travel/accommodation and higher unapproved allowances are excluded. Years 6–10 exclude exchange and further installer costs. Owner-selected full-term labour and installer costs for manual software updates are not covered.; registration: Activate Smart Warranty through the KOSTAL Solar Webshop; the additional five-year Smart Warranty plus phase requires Solar Portal registration. The German instrument states a window within six months after purchase or twelve months after KOSTAL delivery; it does not resolve which clock controls when both dates are known. Confirm unit eligibility rather than choosing an earlier/later deadline. Claims need model/serial, purchase evidence, commissioning report/date, fault information, inverter logs and installation/string/DC details; the installer requests service through support. Required software updates must be reviewed at least every three months. Authorised online updating requires portal/network/internet access; manual updates are offered when online access is not consented to, with installer update costs borne by the owner. Ongoing internet obligations also appear in the instrument; unconditional offline warranty eligibility is not established. KOSTAL's public Garantie page, checked 6 October 2026, states that Smart Warranty activation is possible within the first six months after first commissioning, and that Smart Warranty plus applies to KOSTAL inverters up to 25 kW with a commissioning date from 1 April 2022. The conditions document places its purchase and delivery window in the Solar Portal registration step for Smart Warranty plus and states no separate commissioning-based activation deadline. Neither source states which date controls when several are known; this record relies on the conditions document valid from 1 July 2026.; remedy: KOSTAL normally provides an equivalent exchange unit in advance, but may require return first. Exchange units are generally refurbished, with at least original technical performance unless technical development requires a modification; the remaining original warranty transfers to the exchange unit. Support recommending an exchange does not confirm a warranty case: KOSTAL determines the cause and eligibility. Years 6–10 provide a repair phase with owner-funded shipping and exchange/installer costs. No-fault inspection and cleaning charges may apply; failure to return the defective unit can result in a device-price plus transport invoice. Reimbursements require prior agreement and submission within six months after the analysis result.; removal reinstallation: The installer removes the defective inverter, installs and commissions the exchange unit. The years 1–5 exchange allowance is conditional goodwill rather than an unlimited removal/reinstallation entitlement; years 6–10 exclude exchange and installer costs. The defective unit must be returned in appropriate packaging, with KOSTAL retaining the described device ownership rights. No unconditional full-term removal/reinstallation cover is established.; transferability: An unrestricted transfer right was not established.; transport: For a covered Smart Warranty claim in years 1–5, the appointed parcel service is free when the defective unit is returned within the specified return period; the instrument does not state a universal numeric return deadline. Years 6–10 exclude outbound and return freight, and the owner/installer organises suitable packaging. Overseas territories, islands and non-EU countries have separate conditions; these are not transferred to Germany as unrestricted freight cover.

DE Warranty scope

Before

Germany; conditional ten years after registration. Service and freight narrow materially after year five.

After

Germany; KOSTAL Solar Electric GmbH service and warranty conditions valid from 1 July 2026 (DOC02239562-0007) provide a conditional ten-year 5+5 Smart Warranty / Smart Warranty plus structure from first commissioning for eligible PLENTICORE inverters. Activation and additional Solar Portal registration apply; this is not ten years of identical service or freight coverage. Accessories such as batteries and sensors are outside this instrument. Missing required updates, improper maintenance, software faults/non-compliant settings and exceeding the product-manual backup operating-hour limit are among the exclusions. Applicable unit dates, registration and approved-country conditions must be checked; G2, MP G3 and BI G3 configurations are not substituted for the scored L G3 20.0.

US Support Note

Before

kostal-solar-electric.com/en-us and the United States PLENTICORE path return 404. German VDE-AR-N 4105 evidence is not UL 1741 evidence and is not transferred onto a United States catalogue.

After

kostal-solar-electric.com/en-us and the United States PLENTICORE path return 404. German VDE-AR-N 4105 evidence is not UL 1741 evidence and is not transferred onto a United States catalogue. Re-audited 2026-09-22: this determination rests solely on the fetch failure recorded above, with no independently reachable regional catalogue, store or archived copy consulted. Downgraded to not_reviewed - unavailable was not confirmed, and this pass did not re-fetch to confirm available either.
