FAQ

We offer a full range of products from 1-in-1, 2-in-1, 4-in-1 to 8-in-1, meaning that a single microinverter can connect one, two, four, or eight panels at once. We also have single-phase and three-phase products for different settings.

Our microinverters cover a wide output power from 300 VA to 5000 VA and are compatible with 166/182/210 modules.

Our microinverters have been certified globally and can be seamlessly tied to your local grid. You will always be able to find the right one for your solar journey.

Our microinverters boast high efficiencies. Our excellent 99.8% MPPT efficiency ratings make sure that more of your panel production is turned into usable energy. 

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.

Yes, you can either choose our HMT-2000-4T/MIT-5000-8T high-powered three-phase microinverter or use our single-phase products HMS series to form a three-phase system.

The Hoymiles Smart Power Export Management can intelligently control the output power of the photovoltaic system, and maximize the user’s power generation profits without violating grid export regulations. At the same time, this system can also accurately display the power and production of the photovoltaic system with the measuring meter, so that users can trade check the PV production online according to data on S-Miles Cloud.

In the Hoymiles Export Management solution, Hoymiles gateway DTU-Pro (or DTU-Pro-S) and additional meter (CT optional) are necessary. In the case of export limitation, the meter can be installed at the load side or the grid side.  The gateway DTU will dynamically adjust the PV power production according to the export power or load consumption as measured by the meter, so that the export power does not exceed the preset limit. To display the PV production accurately, the meter needs to be installed at the output of the PV system to enable the user to get the PV power production remotely.

Our failure rate is 0.18% on average.

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

They are installed differently on the AC side, and the trunk version is known for easier installation.

DTU, short for Data Transfer Unit, is a gateway of data collection and transmission. Microinverters can certainly work without DTU, but you will not be able to get the module-level power production data of your PV system, nor can you perform diagnosis and maintenance of your system online. In other words, you will not be able to tap the full module-level capabilities for which microinverters are built in the first place.

Furthermore, buying a DTU is more than buying a small gadget. It gives you free access to our monitoring platform S-Miles Cloud for life. You will have all the operation data at your fingertips. You can check on the module-level data of your PV system in real-time, diagnose any problems remotely, and maintain your system at minimal costs.

Currently, Hoymiles microinverters are grid-tied, but we are in the process of developing off-grid microinverters, and you can look forward to that. Our microinverters can form an AC coupling system with our hybrid inverters. If you are starting from scratch, then you can directly install our hybrid inverter which can work on- and off-grid.
