    up to 6000 Cycles lifespan

Enerhuis

  • ECO Pro

    100% Green Energy Usage, Zero Carbon Emissions

    • Use More of Your Own Renewable Energy
      Use renewable power left over after household consumption to heat water and increase self-consumption.
    • Smart Follow Available Surplus
      Heating starts when sufficient surplus power is available and stops when it falls below operating requirements.
    • No Grid-Powered Top-Ups, Economical and Environment-Friendly
      Turn surplus green power into hot water, without automatic grid-powered top-ups.
  • ECO

    Prioritize surplus green power, supplement with off-peak

    • Surplus Solar Comes First
      Automatically use surplus solar power for heating, making better use of the energy generated at home.
    • Top Up with Off-Peak Power
      Once off-peak periods and heating schedules are configured, hot water usage can be balanced between comfort and cost-efficiency.
    • Automatic Control for Everyday Convenience
      Reduce manual intervention, save energy and your effort.
  • FAST

    Quickly meet hot water needs without weather conditions

    • No Need to Wait for Surplus Solar
      Prioritize comfortable hot water usage, meeting heating needs even on cloudy days or at night.
    • Full-Power Heating
      Heat at full power within the configured equipment and installation limits to raise water temperature quickly.
    • Support Frequent Hot-Water Use
      Temperature-based heating control suits larger households and frequent hot-water use.
  • BOOST

    One-touch quick heating for instant hot water

    • Start with One Touch
      Press the side-mounted Boost button to start rapid heating for extra demand, such as visiting guests or a bath.
    • Customize Each Boost
      Simple operation, no need to readjust the daily running mode
    • Flexible Switching
      Boost ends when the target temperature is reached or the set duration expires. It can also be easily exit or manually canceled, and then return to your regular mode.

FAQ

  • Q
    What are the differences between the four modes of the Smart energy harvester (ECO Pro / ECO / FAST / BOOST)?

    The four modes help you balance energy saving and keep comfort:
    ECO Pro: 100% green power energy usage to maximize energy savings.
    ECO: Prioritizes green power energy, balances green energy and low-cost off-peak power.
    FAST: Full-power heating to achieve comfortable quickly.
    BOOST: Runs at full power for two hours, then automatically returns to the device's default mode.


  • Q
    Can the smart energy harvester work even when my solar panels are not producing power (e.g., at night)?

    Yes. In both ECO and FAST modes, the device automatically uses grid power (prioritizing low-cost off-peak electricity) to ensure your hot water or heating system continues operating uninterrupted, even when there is no sunlight.


  • Q
    Does the Smart energy harvester require daily maintenance?

    The device is designed for long-term maintenance-free operation. Simply keep its installation environment dry and well-ventilated; there are no internal moving parts requiring periodic servicing.


  • Q
    What is the power consumption of the smart energy harvester?

    In standby mode, the energy collector consumes only 3 watts. The device maximum heating load is 3.68 kilowatts, which meets Green Energy Association standards.


  • Q
    Do I need a smart power sensor with a smart energy harvester ?

    The standard configuration includes a current transformer (with a 5-meter cable) with the energy harvester. If the distance between your energy harvester and the electrical panel is less than 5 meters, you do not need to install a smart power sensor. However, if the distance is greater, making direct CT clamp installation impossible, or if you prefer a fully wireless connection for the energy harvester, then a smart power sensor is required. The smart power sensor enables Enerhuis products to be installed without hardwiring a current transformer. By transmitting real-time energy consumption data to your energy harvester, it ensures more efficient household electricity usage.
