Product Overview
This Sun Gold Power 4000W 24V split-phase pure sine wave inverter with charger is made for battery-based power systems that need both 120V and 240V output from one unit. 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.
With 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.
On 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.
Charging 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.

Why This One Makes Sense
This 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. You get 4000W continuous pure sine output with 12,000W surge for 20 seconds, plus a built-in transfer switch with typical 10ms transfer time to help keep power steady during source changes. The integrated 50A ±5A charger with selectable AC input ranges and 0%–100% adjustable charging current supports better control over battery charging behavior, while power saver mode at 19W idle consumption helps reduce standby waste. Add the LCD display, included remote control and BTS cable, and automatic generator start based on battery voltage, and it fits setups that need dependable backup behavior without stacking extra gear.
