  • What is a BWN Power microinverter?

    BWN Power Inventer series microinverters are on/off-grid inverters when working with our EMS series controller, which will magically create a residential solar storage system that will support battery mode operation without mains power. In addition, the independent MPPT input ensures the MAX output of each solar panel. Since the 25-year lifespan of microinverters is designed to be the same as the solar panel, customers do not need to worry about the hassle of replacing the inverter after a few years.

  • Why choose BWN Power microinverter?

    Most customers are unaware of limitation of the today's solar technology. So, to address the limitation we have invented a microinverter technology that is completely grid agnostic. This means that even if the grid fails and there is no sufficient sunlight, the BWN Power energy system will continue to produce energy and meet the demands of the home or business.

    The BWN Power microinverter system's capabilities further enhanced when the ensemble technology is incorporated into our AC battery storage solution. With BWN Power microinverter series you can have a system that will continuously produce energy, regardless of the presence or absence of the grid that is solar during the day and storage at night.

    That is what we mean by always on and it can address challenges like those the other island nations and countries with weak grids. We also believe BWN Power series microinverter will grow our total addressable market worldwide. For example, there are over 1.2 billion people with limited or no access to energy in regions.

  • Does BWN Power microinverter support three-phase systems?

    Yes, you can either choose our HMT-2250 high-powered three-phase microinverter or use our single-phase products to form a three-phase system.

  • How does BIWN microinverter cope with high temperatures?

    First of all, we put electrolytic capacitor, the most important and fragile component of a microinverter in the coolest part inside its body, ensuring the longevity of the microinverter while not compromising the overall performance.
    Second, our microinverter is known for high conversion efficiency, namely converting almost all DC current generated by PV modules into usable AC current. The higher the conversion efficiency, the less the heat produced. BWN Power microinverters got the best CEC weighted efficiency of 96.5% and CEC peak efficiency of 96.7%. The industry-leading efficiency maximizes the energy harvest and helps users get the best returns on their solar investment.
    The enclosure of the BWN Power microinverter is designed in such a way that dissipates heat quickly (natural convection). The aluminum enclosure makes the product light and more erosion resistant.
