SunGoldPower Split-Phase Inverter Charger | 4000W Pure Sine Wave | 12V DC–120/240V AC

High-Performance Split-Phase Inverter Charger for Home, RV & Off-Grid Power

The SunGoldPower LFP4K12V240VSP is a powerful 4000W split-phase pure sine wave inverter charger designed to support residential, off-grid, RV, and backup power systems. Built on a rugged low-frequency platform, this all-in-one unit integrates a pure sine wave inverter, intelligent high-capacity battery charger, and automatic AC transfer switch to deliver stable, reliable power for both standard and high-voltage appliances.

With 120V/240V split-phase output, this inverter supports a wide range of household and light industrial loads, including tools, pumps, and appliances that require higher voltage—making it ideal for advanced off-grid and backup installations.

Key Features

4000W Low-Frequency Pure Sine Wave Output: Provides clean, utility-grade power with high surge capability for electronics, appliances, and motor-driven equipment.
Split-Phase 120V / 240V AC Output: Supports both standard 120V loads and 240V appliances, offering maximum flexibility for home and off-grid systems.
All-in-One Inverter Charger Design: Combines inverter, smart charger, and automatic transfer switch for seamless switching between AC input and battery power.
12VDC Battery Input: Designed for 12V battery banks commonly used in mobile, RV, and off-grid applications.
240VAC AC Input Required: Accepts 240VAC input to enable split-phase operation and charging functionality.
Selectable Output Frequency: Supports 50Hz or 60Hz output via SW4 switch for global compatibility.
AC / Battery Priority Selection: Choose AC or battery as the primary power source using the SW5 switch.
Adjustable Charging Current: Linear adjustment from 0% to 100% allows precise control of battery charging rates.
High-Capacity Smart Charger: Integrated multi-stage charger up to 120A, with support for 7 battery types including LiFePO₄, AGM, Gel, and lead-acid (charger-disable option available).
Automatic Generator Start (AGS): Automatically starts and stops a generator based on battery voltage for fully automated backup power.
Low Idle Power Consumption: Efficient standby operation reduces battery drain and extends system runtime.
Fast AC Transfer Time: Typical ~10ms transfer time ensures uninterrupted power delivery.
Advanced Monitoring & Control: Features LCD display, remote control, and Battery Temperature Sensor (BTS) for accurate monitoring and safe charging.

Understanding Your Power Needs

Power Calculation Guide

Sizing Metric	Formula & Example
Energy Consumption (Wh)	Formula: Watts × Hours Example: 60W × 4 hrs = 240 Wh
Battery Capacity (Ah)	Formula: Watt-hours ÷ System Voltage (V) Example: 240 Wh ÷ 12V = 20 Ah
Inverter Size (W)	Formula: Total Watts × 1.25 (safety margin) Example: 300W × 1.25 = 375W → Use 400W inverter
Total Load Power (W)	Formula: Sum of all appliance watts used simultaneously Example: Light (10W) + Fan (75W) = 85W
Runtime (hrs) of Battery	Formula: (Battery Ah × Voltage) ÷ Total Load (W) Example: (100Ah × 12V) ÷ 240W = 5 hrs

Find Your Power Match

Need / Application	System Recommendation
Basic lighting + phone charging	Recommended Battery: 50Ah – 100Ah (12V) Inverter Size: 100W – 200W Notes: For small backup setups
Home office (laptop, fan, TV)	Recommended Battery: 150Ah – 200Ah (12V or 24V) Inverter Size: 500W – 1000W Notes: For moderate usage with 4–6 hours of backup
Home backup (fridge, lights)	Recommended Battery: 200Ah+ (24V or 48V recommended) Inverter Size: 1000W – 1500W Notes: Ideal for longer backups or heavier loads
Business / shop power backup	Recommended Battery: 300Ah+ (48V system) Inverter Size: 2000W – 3000W Notes: Suitable for commercial setups or extended power outages
