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: 4.0kg
* Easy integration into custom enclosures or existing systems.
* Optional accessories: terminal blocks, self-recovering fuses, and display module.
