It is a low-frequency split-phase inverter with a built-in battery charger and an AC auto-transfer switch, designed for home, business, RV, trailer, boat, off-grid, and emergency backup applications. The goal is straightforward: run a wide range of appliances on clean power, recharge the battery bank from AC input, and switch sources automatically when incoming power is interrupted.\u003c\/p\u003e\n\u003cp\u003eWith split-phase 120VAC and 240VAC output, it supports mixed loads without forcing you to choose between standard outlets and higher-voltage appliances. The output waveform is pure sine wave and includes bypass mode, delivering stable AC output for everyday use. It is rated for 4000W continuous output with a surge rating of 12,000W for 20 seconds, providing extra headroom for short start-ups and momentary demand spikes. Typical transfer time is 10ms, helping keep power steady when switching between AC input and battery power.\u003c\/p\u003e\n\u003cp\u003eOn the battery side, it is designed around a 24V system with a nominal input voltage of 24V and a minimum start voltage of 20V. It includes a low battery alarm range of 21V to 22V, a selectable low battery trip range of 20V to 21V, a high voltage alarm of 32V, and a low battery restart voltage of 26V. For standby efficiency, idle consumption is 48W, with power saver mode idle consumption of 19W, which helps reduce waste when the system is waiting between charging cycles or backup events.\u003c\/p\u003e\n\u003cp\u003eCharging is handled by an integrated AC charger rated at 50A ±5A. The AC input range is selectable between 140–270VAC and 184–253VAC, and charge settings are selectable based on battery type with adjustable charge current from 0% to 100%. Battery charging follows a 3-step intelligent charging process, and overcharge protection shutdown is specified at 31.4V. The unit supports AC or battery priority selection and includes automatic generator start based on battery voltage, plus an LCD display for system monitoring. Remote control and a BTS cable are included for easier control and battery temperature sensing support.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4000W low-frequency pure sine wave inverter with charger\u003c\/li\u003e\n\u003cli\u003eInverter, battery charger, and AC auto-transfer switch combined in one unit\u003c\/li\u003e\n\u003cli\u003eSplit-phase design supporting 120V and 240V output\u003c\/li\u003e\n\u003cli\u003eAC or battery priority selectable\u003c\/li\u003e\n\u003cli\u003eAutomatic generator start based on battery voltage\u003c\/li\u003e\n\u003cli\u003eAdjustable charging current from 0% to 100%\u003c\/li\u003e\n\u003cli\u003eSupports 50Hz or 60Hz output frequency\u003c\/li\u003e\n\u003cli\u003eLow idle current for improved efficiency\u003c\/li\u003e\n\u003cli\u003eLCD display for system monitoring\u003c\/li\u003e\n\u003cli\u003eRemote control and BTS cable included\u003c\/li\u003e\n\u003cli\u003eSuitable for home, business, RV, trailer, boat, off-grid, and backup applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous output power: 4000W\u003c\/li\u003e\n\u003cli\u003eSurge rating: 12000W, 20 seconds\u003c\/li\u003e\n\u003cli\u003eAC output voltage: 120VAC and 240VAC\u003c\/li\u003e\n\u003cli\u003eAC input voltage: 240VAC\u003c\/li\u003e\n\u003cli\u003eOutput waveform: pure sine wave, bypass mode\u003c\/li\u003e\n\u003cli\u003eTypical transfer time: 10ms\u003c\/li\u003e\n\u003cli\u003eNominal efficiency: greater than 88%\u003c\/li\u003e\n\u003cli\u003eNominal input voltage: 24V\u003c\/li\u003e\n\u003cli\u003eMinimum start voltage: 20V\u003c\/li\u003e\n\u003cli\u003eLow battery alarm: 21V–22V\u003c\/li\u003e\n\u003cli\u003eLow battery trip: 20V–21V, selectable\u003c\/li\u003e\n\u003cli\u003eHigh voltage alarm: 32V\u003c\/li\u003e\n\u003cli\u003eLow battery restart voltage: 26V\u003c\/li\u003e\n\u003cli\u003eIdle consumption: 48W\u003c\/li\u003e\n\u003cli\u003ePower saver mode idle consumption: 19W\u003c\/li\u003e\n\u003cli\u003eCharger rate: 50A ±5A\u003c\/li\u003e\n\u003cli\u003eAC input range: 140–270VAC, 184–253VAC selectable\u003c\/li\u003e\n\u003cli\u003eOvercharge protection shutdown: 31.4V\u003c\/li\u003e\n\u003cli\u003eSelectable charge settings based on battery type, adjustable charge current 0%–100%\u003c\/li\u003e\n\u003cli\u003e3-step intelligent battery charging\u003c\/li\u003e\n\u003cli\u003e4000W 24V low-frequency pure sine inverter\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003eBTS cable\u003c\/li\u003e\n\u003cli\u003eUnit weight: 55 lb\u003c\/li\u003e\n\u003cli\u003eUnit size: 22 × 9.1 × 7.5 inch\u003c\/li\u003e\n\u003cli\u003eShipping weight: 64 lb\u003c\/li\u003e\n\u003cli\u003eShipping size: 27 × 13.4 × 13 inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat’s Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4000W 24V low-frequency pure sine inverter\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003eBTS cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eBest For\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHome backup systems needing split-phase 120VAC and 240VAC output\u003c\/li\u003e\n\u003cli\u003eOff-grid cabins and workshops using a 24V battery system\u003c\/li\u003e\n\u003cli\u003eRV, trailer, and marine setups that need pure sine power\u003c\/li\u003e\n\u003cli\u003eSystems needing integrated AC charging at 50A ±5A with 0%–100% charge current adjustment\u003c\/li\u003e\n\u003cli\u003eGenerator-backed setups using automatic transfer and automatic generator start based on battery voltage\u003c\/li\u003e\n\u003cli\u003eLoads that benefit from 12,000W surge capability for short start-ups\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy This One Makes Sense\u003c\/h2\u003e\n\u003cp\u003eThis unit is a practical way to build a 24V battery-based power system that can run both 120V and 240V loads while keeping installation clean.
