-
Q:Does every product include online monitoring?A:
Absolutely. S-Miles Cloud, our smart monitoring platform, is available for every product online or on your mobile device.
-
Q:Are your microinverters certified for safety and standards compliance?A:
Yes – you can click here to see a full list of the relevant certificates.
-
Q:Can your microinverters limit output power?A:
Yes – you can use either a zero-export function or a power adjustment function depending on your specific needs.
-
Q:Why is the LED on my microinverter flashing red?A:
This may indicate an issue with your grid voltage. Contact your installer for more support.
-
Q:What is MPPT efficiency?A:
Maximum Power Point Tracking (MPPT) is a technique used with variable power sources to maximize energy extraction as conditions vary.
MPPT efficiency represents how effectively a microinverter tracks to the maximum power point. In short, the higher the efficiency, the more output power you will get from each panel. Ultimately, this determines the return on your solar investment.

Q:What are the advantages of Hoymiles compared with other microinverter makers?A:
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.
-
Q:Does Hoymiles microinverter support three-phase systems?A:
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.

Q:How does Hoymiles microinverter achieve power export management ?A:
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.
