Each unit communicates over \u003cstrong\u003epower-line communication (PLC)\u003c\/strong\u003e back to the IQ Gateway for real-time monitoring and remote firmware updates, and it ships with \u003cstrong\u003eintegrated Stäubli MC4 DC connectors\u003c\/strong\u003e for a tool-free panel connection. Fully compliant with \u003cstrong\u003eG98, G99 and G100\u003c\/strong\u003e grid connection standards, the IQ9N is designed to grow with your system — it is backward-compatible with existing \u003cstrong\u003eIQ7 and IQ8\u003c\/strong\u003e installations and carries an \u003cstrong\u003eindustry-leading warranty of up to 25 years\u003c\/strong\u003e when paired with an internet-connected IQ Gateway.\u003c\/p\u003e\n\n  \u003c!-- STAT STRIP --\u003e\n  \u003cdiv style=\"display:flex; flex-wrap:wrap; gap:10px; margin:24px 0;\"\u003e\n    \u003cdiv style=\"background:#008377CF; color:#fff; border-radius:8px; padding:14px 18px; flex:1; min-width:130px; text-align:center;\"\u003e\n      \u003cdiv style=\"font-size:22px; font-weight:700;\"\u003e427 VA\u003c\/div\u003e\n      \u003cdiv style=\"font-size:12px; margin-top:4px;\"\u003eMax Apparent Power\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#008377CF; color:#fff; border-radius:8px; padding:14px 18px; flex:1; min-width:130px; text-align:center;\"\u003e\n      \u003cdiv style=\"font-size:22px; font-weight:700;\"\u003e97.44%\u003c\/div\u003e\n      \u003cdiv style=\"font-size:12px; margin-top:4px;\"\u003eEU Weighted Efficiency\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#008377CF; color:#fff; border-radius:8px; padding:14px 18px; flex:1; min-width:130px; text-align:center;\"\u003e\n      \u003cdiv style=\"font-size:22px; font-weight:700;\"\u003e600 W\u003c\/div\u003e\n      \u003cdiv style=\"font-size:12px; margin-top:4px;\"\u003eMax DC Input Power\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#008377CF; color:#fff; border-radius:8px; padding:14px 18px; flex:1; min-width:130px; text-align:center;\"\u003e\n      \u003cdiv style=\"font-size:22px; font-weight:700;\"\u003eIP67\u003c\/div\u003e\n      \u003cdiv style=\"font-size:12px; margin-top:4px;\"\u003eOutdoor Ingress Rating\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#008377CF; color:#fff; border-radius:8px; padding:14px 18px; flex:1; min-width:130px; text-align:center;\"\u003e\n      \u003cdiv style=\"font-size:22px; font-weight:700;\"\u003e25 Yrs\u003c\/div\u003e\n      \u003cdiv style=\"font-size:12px; margin-top:4px;\"\u003eWarranty (with IQ Gateway)\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#008377CF; color:#fff; border-radius:8px; padding:14px 18px; flex:1; min-width:130px; text-align:center;\"\u003e\n      \u003cdiv style=\"font-size:22px; font-weight:700;\"\u003eG98\/G99\u003c\/div\u003e\n      \u003cdiv style=\"font-size:12px; margin-top:4px;\"\u003eGrid Compliance\u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- RED CALLOUT: Installer requirements --\u003e\n  \u003cdiv style=\"border-left:5px solid #c0392b; background:#fdf2f2; padding:14px 18px; border-radius:6px; margin:20px 0;\"\u003e\n    \u003cstrong style=\"color:#c0392b;\"\u003e⚠ Installer Requirements\u003c\/strong\u003e\n    \u003cp style=\"margin:8px 0 0;\"\u003eThe IQ9N Microinverter must be installed by a \u003cstrong\u003ecompetent, suitably qualified electrical installer\u003c\/strong\u003e in accordance with \u003cstrong\u003eBS 7671 (IET Wiring Regulations)\u003c\/strong\u003e and all applicable local Building Regulations.
