Microinverter

*Unmatched Safety Features: Microinverters offer unparalleled safety compared to string solar systems. Unlike the high DC voltage in a solar array of string systems, microinverter systems connect modules in parallel, each carrying voltages within 60V. This substantial reduction in voltage significantly minimizes safety risks. Consequently, microinverter systems effortlessly meet rapid shutdown requirements, and our microinverters comply with specifications outlined in UL 1741 and NEC 2017/2020 690.12.
*Effortless Monitoring and Maintenance: Microinverters provide module-level monitoring, allowing users to remotely check the real-time operation data and performance of each module. This capability enables the timely detection of potential issues, simplifying the maintenance process.
*Exceptional Efficiency: Microinverters are renowned for their module-level Maximum Power Point Tracking (MPPT), ensuring independent operation of PV modules. In cases of shading or underperformance in some modules, others remain unaffected. This feature guarantees 5-30% more energy output in residential, industrial, and commercial power systems compared to traditional inverters.
*Reliability Assurance: Our microinverters boast an IP67 enclosure rating, indicating robust resistance to dust and water ingress. With this IP67 rating, our microinverters ensure high durability and reliability, maintaining optimal performance even in challenging environmental conditions.
*Optimize Rooftop Space: Our module-level MPPT allows panels to be arranged according to the available space on your rooftop. This flexibility proves to be cost-effective, especially if your rooftop features slopes facing different directions.
*Industry-Leading Warranty: Our microinverters come with a standard 10-year warranty, extendable up to 25 years, demonstrating our commitment to providing a reliable and long-lasting solar solution.

*We offer a full range of products from single-in to quad-in configurations. This means that a single microinverter has the capability to connect one, two, four or more panels simultaneously.
*Covering a broad output power spectrum ranging from 500VA to 2800VA, our microinverters are compatible with PV modules featuring 60~75 cells and 120~150 half cells. The BYM2800 solution stands out with the industry’s highest maximum output power, boasting a continuous input current of 20A.
*Our solution features an industry-leading wide operating temperature range (-40°C to +70°C), reinforced by a comprehensive thermal design incorporating full potting, thermal grease, and thermal pads technology.
