Q:What are the advantages of microinverters?A:
Module-level monitoring and easy maintenance: Microinverters enable module-level monitoring, so users are able to check the operation data and performance of each and every module remotely in real-time and detect potential problems in time. This makes maintenance super easy. High efficiency: Microinverters are known for their module-level MPPT which means that PV modules operate independently of each other and would not be influenced in case some are underperforming due to shading. Therefore, in residential, industrial, and commercial power plants, microinverters guarantee 5–30% more energy output than traditional inverters. Reliability guaranteed: Hoymiles microinverter is marked by the IP67 enclosure rating. IP stands for “ingress protection”, and is a a rating system that assesses the resistance of an enclosure against water and dust. The grade is represented by two numerals, the first one indicating the protection degree against dust and the second one showing the protection against water. In the case of our enclosure rating of IP67, it means the equipment is dust-tight and is protected against the effects of temporary immersion in water. More specifically, our microinverters are tested to still perform well after being immersed 1 m in water. Make full use of your rooftop space: Our module-level MPPT means that panels can be placed in a way that the space on your rooftop allows. This is particularly cost-effective if your rooftop has slopes facing different directions. Industry-leading warranty: Our microinverter comes with a standard 12 years of warranty and is extendable to 25 years. Click here to learn more about our warranty information.

Q:What is Hoymiles' annual manufacturing capacity?A:
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.

Q:Are Hoymiles microinverters compatible with high-power PV modules?A:
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.

Q:What is the DC/AC ratio of Hoymiles microinverters?A:
We recommend that the ratio be between 0.8 and 1.35 depending on your solar project.
-
Q:How does Hoymiles microinverter cope with high temperatures?A:
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.
-
Q:What are the protection mechanisms of Hoymiles microinverters?A:
Our microinverters are built with all-around protection mechanisms such as anti-islanding protection, input reverse polarity protection.
