    Features and benefits

    Why I love EASUN Hybrid Solar Inverter 6.5KW

    • Rated power 6.5kW/6.5kVA, power factor 1: This robust power rating ensures the inverter can handle significant electrical loads, providing 6.5 kilowatts of continuous power and 6.5 kilovolt-amperes of apparent power. A power factor of 1 indicates exceptional efficiency, meaning virtually all the power drawn is converted into useful work, minimizing energy waste and maximizing the performance of connected appliances and systems.
    • Dual AC output: The inclusion of dual AC outputs offers enhanced flexibility for power distribution. Users can segment their loads into critical and non-critical circuits, ensuring essential appliances remain powered even during specific operational modes or grid outages, thereby increasing system reliability and user convenience.
    • MPPT range 60V~450V, 500Voc: With a wide Maximum Power Point Tracking (MPPT) voltage range from 60V to 450V and a maximum open-circuit voltage (Voc) of 500V, this inverter can efficiently harvest power from a broad array of solar panel configurations. This wide range optimizes solar energy capture throughout the day and across varying weather conditions, leading to higher overall system efficiency and energy yield.
    • Feed-in to grid: The «Feed-in to grid» capability allows the inverter to export surplus solar energy back to the utility grid. This feature is crucial for grid-tied systems, enabling users to potentially earn credits or compensation from their utility provider, effectively reducing electricity bills and contributing to a more sustainable energy ecosystem.
    • High frequency with small size and light weight: Utilizing high-frequency technology, the inverter achieves a compact form factor and reduced weight (10-22KG, 560*375*185mm). This design simplifies installation, requires less physical space, and makes the unit easier to transport and handle, offering practical advantages for both installers and end-users.
    • Pure sine wave AC output: The inverter produces a pure sine wave AC output, which is identical to the power supplied by the utility grid. This ensures compatibility with all types of electronic devices, including sensitive equipment like computers, medical devices, and audio systems, preventing damage and ensuring their optimal performance without distortion or interference.
    • Solar and grid power loads at the same time: This hybrid functionality allows the inverter to intelligently combine power from both solar panels and the utility grid to supply connected loads simultaneously. This maximizes the utilization of solar energy, reduces reliance on grid power, and provides a seamless power supply, especially beneficial during periods of high demand or fluctuating solar irradiance.
    • WIFI remote monitoring (optional): The optional WiFi remote monitoring feature provides users with the convenience of real-time data access and control over their solar system from anywhere. This allows for easy tracking of energy production, consumption, battery status, and system alerts via a smartphone or computer, facilitating proactive management and troubleshooting.
    • Ability to work without battery: A significant advantage, this inverter can operate and supply power directly from solar panels to loads even without a connected battery bank. This reduces initial system costs, simplifies installation, and offers a viable solution for applications where battery storage is not immediately required or desired.
    • CAN/RS485 for BMS communication: Equipped with CAN and RS485 communication ports, the inverter can directly interface with Battery Management Systems (BMS). This intelligent communication ensures optimal charging and discharging of compatible battery banks, prolonging battery life, enhancing safety, and improving overall system efficiency and reliability.
    • 9 inverters in parallel: The capability to parallel up to 9 inverters allows for significant scalability of the solar power system. This means users can expand their power capacity as their energy needs grow, reaching up to 58.5kW (9 x 6.5kW), making it suitable for larger residential, commercial, or industrial applications without needing to replace the entire system.
