4.2KW PURE SINE WAVE HYBRID INVERTER: Designed for 24V battery systems with 4.2kW rated AC output and a built-in 120A MPPT solar charger. Supports up to 6200W PV array input, 27A max PV current, 60–450V MPPT operating range and 500V max PV open-circuit voltage. UPGRADED PERFORMANCE: 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. ADVANCED LITHIUM BATTERY INTEGRATION: Supports compatible lithium battery BMS communication via RS485, allowing battery information to be exchanged with the inverter. The LCD can display battery SOC, total voltage, charge/discharge current, cell temperature and cycle information. PYLON and PACE protocol options are available in the inverter settings, while WiFi remote monitoring is optional. BATTERY-FREE SOLAR OPERATION: The inverter can operate with or without a battery, giving users greater flexibility when building or expanding a solar power system. In battery-free operation, available PV power can supply connected loads directly, while the pure sine wave output is designed for household and backup applications. SMART DUAL AC OUTPUT: Separate main and second-load outputs allow priority-based load management. The 4.2kW model provides 4200W main output and an adjustable second-load range of 840–2940W. Suitable for home backup, off-grid systems and applications using mains or generator input, with 23V cold-start voltage and built-in protection functions.
