Bezeichnung bei Amazon: Y&H 4,2KW On/Off-Grid-Hybrid-Solarwechselrichter DC24V zu AC220V integrierter 120A MPPT 6200W 27A PV-Eingang batterieloser Betrieb doppelter AC-Ausgang Offline-Firmware-Upgrade für Heim-Energie

• Reine Sinuswelle mit 4,2 kW Leistung und integriertem 120-A-MPPT-Solarladegerät. Verbesserter maximaler PV-Eingangsstrom auf 27 A (von 18 A), unterstützt eine maximale PV-Anlagenleistung von 6200 W. MPPT-Spannungsbereich: 60–450 VDC, maximale Leerlaufspannung 500 VDC. Verfügt über zwei Wechselstromausgänge (Hauptstrom 4200 W + Nebenstrom 840–2940 W), einstellbare Hauptlast-Abschalt-/Rückspannung…
• New offline firmware upgrade function via COMM port allows software updates. Enhanced 27A PV input current increases solar energy harvesting by 50%. Optimized circuit design eliminates electromagnetic interference, ensuring stable operation of sensitive electronics like smartphones, tablets, and communication equipment without disruption.
• Enhanced LIB-485 communication protocol enables seamless BMS connectivity with automatic parameter synchronization. LCD interface directly displays battery SOC, total voltage, charge/discharge current, cell temperatures, and cycle count. WiFi APP (optional) shows comprehensive lithium battery data in real-time. When batteries reach 100% charge, system automatically reduces grid input current to…
• Revolutionary PV-only mode upgraded with intelligent current limiting technology prevents output voltage collapse, allowing larger loads to run directly from solar power without battery backup. Prevents frequent shutdowns during fluctuating solar conditions and ensures reliable pure sine wave output for all appliances including refrigerators and air conditioners.
• Two independent AC outputs enable priority-based load shedding—critical loads remain powered while secondary circuits disconnect at user-defined voltage thresholds. Ideal for off-grid homes, cabins, emergency backup power, areas with frequent outages, and grid-tie energy savings. Compatible with mains or generator input, cold start function (23V), and comprehensive protection systems.
