4000W DC 24V Split Phase Pure Sine Wave Inverter With Charger – All-in-One Power for Off-Grid and Backup Systems

Power your home, cabin, or mobile setup with confidence using the 4000W DC 24V Split Phase Pure Sine Wave Inverter With Charger from the LFP Series. Designed for high reliability and flexibility, this inverter combines a pure sine wave inverter, intelligent battery charger, and automatic transfer switch into a single unit. It delivers stable 120V or 240V output for a wide range of residential and commercial applications.

Pure Sine Wave Technology – Stable & Efficient

With low-frequency pure sine wave output, this 4000-watt inverter provides clean, reliable power suitable for sensitive electronics, tools, and major appliances. Adjustable 50/60Hz output makes it compatible with both domestic and international power standards.

Dual Voltage Split Phase Output

Perfect for powering both 120V and 240V appliances, this inverter requires a 240VAC input and delivers dual-phase output, ideal for homes, workshops, and remote operations.

Smart Charging & Generator Auto-Start

Features an adjustable charging current (0–100%) via linear switch, giving you complete control over battery charging. It includes an automatic generator start function that kicks in when battery voltage drops too low, then shuts the generator off once charging completes—keeping your system running smoothly and autonomously.

Flexible Priority Modes

By default, this inverter is set to AC priority mode, but with the simple flick of SW5, you can switch to battery priority—making it adaptable for both grid-connected and off-grid scenarios.

Complete System Integration

Includes a Battery Temperature Sensor (BTS) cable and remote control for safe, optimized charging and convenient monitoring. Low idle current ensures maximum efficiency, even during standby.
