1. Pure Sine Wave Inverter
Delivers grid-equivalent stable power to safeguard sensitive devices (laptops, home appliances, medical equipment) from voltage fluctuations, ensuring seamless, damage-free operation.
2. Cold Start Function
Reliably initiates power supply even in low-temperature environments (-20°C to 0°C typical), perfect for outdoor use, remote areas, or winter conditions.
3. Selectable Input Voltage Range
Customize voltage settings to match different home appliances (e.g., 110V for US devices, 230V for EU gear) and personal computers, enhancing compatibility across scenarios.
4. Selectable Charging Current
Adjust charging speed based on application needs—high current for fast charging (e.g., emergency power) or low current for battery maintenance, balancing efficiency and safety.
5. Configurable AC/Solar Priority (LCD Control)
Easily set power input priority (AC mains first or solar first) via intuitive LCD panel, optimizing energy use for off-grid (solar-heavy) or on-grid (mains-backed) setups.
6. Dual Compatibility: Mains & Generator
Seamlessly connects to standard mains voltage or generator power, serving as a versatile backup or primary power source for homes, offices, or construction sites.
7. Auto-Restart on AC Recovery
Automatically resumes operation once AC mains power is restored, eliminating manual reboots and ensuring uninterrupted power for critical devices.
8. Overload & Short Circuit Protection
Built-in safety mechanisms cut off power instantly when overloads or short circuits occur, protecting the inverter, connected devices, and batteries from damage.
9. Smart Battery Charger
Adopts multi-stage charging technology (bulk, absorption, float) to extend battery lifespan, prevent overcharging, and maintain optimal battery performance long-term.
