Yes – you can use either a zero-export function or a power adjustment function depending on your specific needs.

Hoymiles has been on the fast track and our annual production capacity has reached 2 million units on average. From 2016 to 2021, we registered a 100% increase in sales volume every year. As of 2022, over 1 million Hoymiles microinverters have been installed across more than 100 countries and regions. Our service network now spans more than 76 countries and regions and this number is expected to grow in the years to come.

Our microinverters feature a full-range lineup spanning from 300VA up to 5000 VA and they are compatible with all the mainstream 166/182/210mm modules with power ranging from 300W to 670W. Our microinverters are incredibly flexible as they can be connected to one, two, four, and eight modules at a time which are called 1-in-1, 2-in-1, 4-in-1, and 8-in-1 respectively in the Hoymiles ecosystem. It means that you don’t need to have as many inverters as the modules. For example, if your space is limited and you can only install two panels, then you can choose one of our 2-in-1 microinverters instead of two regular microinverters. You can always find a product that suits your needs because we are ready to fit you into any installation setting. Check our product list for more details and you’re very welcome to talk to our experts if you are still not sure which products to buy.

We recommend that the ratio be between 0.8 and 1.35 depending on your solar project.

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 as much DC current generated by PV modules into usable AC current as possible. The higher the conversion efficiency, the less the heat produced. Hoymiles 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 Hoymiles microinverter is designed in such a way that dissipates heat quickly (natural convection). The aluminum enclosure makes the product light and more erosion resistant.

Our microinverters are built with all-around protection mechanisms such as anti-islanding protection, input reverse polarity protection.
