Fronius Primo GEN24 Plus 6.0 — 6kW Hybrid String Inverter with Emergency Power

The Fronius Primo GEN24 Plus 6.0 is a single-phase hybrid string inverter combining the generation efficiency of a high-voltage string inverter (1000V DC input) with the backup capability of a battery-coupled hybrid — without requiring a separate hybrid inverter or battery inverter. Emergency Power Supply (EPS) mode provides 3kW of backed-up AC power during grid outages directly from the battery, with transfer time <5 seconds. SnapINverter wall-mount mechanism enables tool-free installation and replacement. DC input: Voc max 1000V, 2 independent MPPT trackers (380–800V MPPT range). AC grid: single-phase 230V 50Hz. Peak efficiency: 97.6% (inverter), 98.5%+ (MPPT). Compatible battery systems: BYD Battery-Box Premium LVS/LVL (48V series), BYD HVM (102–409V high-voltage), and Fronius Solar Battery. Battery DC voltage range: 40–60V (low-voltage) or up to 409V (high-voltage with HVM stack). Fronius Solar.web cloud monitoring: string-level yield, weather overlay, feed-in tariff tracking, and anomaly alerts via email/SMS. Open API for integration with home automation systems. Zero feed-in mode for export-limited grids. Built-in arc-fault current interrupter (AFCI). IP66, fanless. Weight: 19.9kg. Dimensions: 645 × 431 × 204mm. CE marked to EN 50549 for European anti-islanding; suitable for international markets with VDE-AR-N 4105 compliance.
