Product Description

Features

Bi-Directional Power Conversion
 * DC to AC: Delivers 3000W continuous (6000W peak) pure sine wave AC output.
 * AC to DC: Built-in smart charger with up to 30A max charging current (12V system).
 * Seamlessly switches between grid power and battery mode, making it ideal for backup power and off-grid applications.
 

Multi-Battery Compatibility
 * Supports Lead-Acid, Lithium (LiFePO4), Gel, and Water batteries with automatic voltage recognition (12V/24V DC).
 * Advanced 3-stage charging (Constant Current, Constant Voltage, Float) ensures efficient and safe battery maintenance.
 

Clean & Stable Pure Sine Wave Output
 * THD ≤ 3% – Provides utility-grade power quality, safe for sensitive electronics like laptops, medical devices, and audio
 systems.
 

True UPS Functionality
 * Ultra-fast transfer time: ≤15ms (grid to inverter)
 * Ensures continuous operation for critical loads during power outages.
 

Comprehensive Protection & Safety
 * Full protection: Overload, Short Circuit, Over/Under Voltage, Overheating, Reverse Polarity.
 * Intelligent thermal management: Triple-fan cooling system activates at 45°C.
 * Overheat protection at 90°C with auto-recovery at 60°C.
 

Real-Time Monitoring & Control
 * Optional LCD display and wireless remote control for real-time monitoring of:
 * Input/Output Voltage, Power, Frequency
 * Battery Status, Charging Current, Fault Codes (e.g., Overload, Short Circuit)
 * Clear LED indicators for operational status: Green (normal), Red (fault/charging), Yellow (warning).
 

Compact & DIY-Friendly
 * Dimensions: 380×215×70mm | Weight: 4kg
 * Easy integration into custom enclosures or existing systems.
 * Optional accessories: terminal blocks, self-recovering fuses, and a display module.
