Solar inverters (string inverters, microinverters, and hybrid/multi-mode inverters) are classified under 8504.40 as static converters. A hybrid inverter with integrated battery management system (BMS) and EPS (emergency power supply) function is still 8504.40 — the primary function is DC-AC power conversion. MPPT charge controllers (Maximum Power Point Tracking units managing battery charging from solar panels) are also 8504.40. Grid-tied inverters with reactive power control and anti-islanding protection are 8504.40. Anti-dumping duties: the EU and US have both investigated Chinese-origin inverters — check TARIC and USITC ADD orders. UL 1741 (US) and EN 62109 (EU/UK) certifications are required for grid-connected installations.
