Supplier's note

  1. Three Breakthroughs:

    • Pure Sine Wave Output: Eliminates device damage risks common with modified sine wave inverters.
    • Integrated Charger: Reduces system complexity by combining inverter and charger functions.
    • 85% Efficiency: Outperforms standard inverters (typically 75-80%), saving energy in solar setups.

  2. Version Selection Guide:

    • Base Model: Best for households with standard loads (e.g., TVs, lights). Its 3000W capacity handles most daily needs without excess cost.
    • Advanced Model: Ideal for solar systems with high-demand appliances (e.g., microwaves). The +50% surge power and extended certifications (RoHS) suit commercial or semi-industrial use.
    • Pro Model: Tailored for heavy-duty scenarios like marine applications or industrial backups. The 6000W surge and IP54 rating ensure reliability in harsh environments.

With the Pro’s 92% efficiency, you can reduce battery size by 15% compared to older models—saving space and costs. Pair its IP54 rating with outdoor solar arrays to withstand dust and moisture.
