If you are a new installer of Hoymiles, and have not had your installer account before, please approach your distributor to create an account;

If you are our new distributor, please tell us your sales contact and account ID you want, and email to service@hoymiles.com, we will create one for you.

If you are an end-user, please contact your installer for your login details.

1. Verify that the voltage and current specifications of the PV module match those of the microinverter.
• The maximum open circuit voltage rating of the PV module must be within the operating voltage range of the microinverter.
• We recommend that the maximum current rating at MPP should be equal to or less than the maxi- mum input DC current.

2. The output DC power of PV module shall not exceed 1.35 times of the output AC power of the microinverter. Refer to “Hoymiles Warranty Terms & Conditions” for more information.

If you still need further help, please send the specification of the panel to service@hoymiles.com

As a Hoymiles partner, you can access a range of training courses as well as useful resources for improving your product knowledge and technical capability. Find out more on our training page or contact us for more details.

To help you find the right fit for every location, you can connect via WiFi, GPRS or LAN depending on your specific products.

If your system has stopped reporting data, S-Miles Cloud can help you uncover the root cause. After logging in, check whether your station is listed as ‘offline’. If so, check your DTU is connected to the internet (indicated by a flashing green LED). If the DTU seems to be online but still isn’t connecting with S-Miles Cloud, check that you have entered the correct serial number.

Maximum WiFi range depends on the materials between the sender and receiver.

Yes, providing they use the same method of connection.

For the daisy chain version, 12Awg. For bus versions, a choice of 10Awg or 12Awg.

Yes – contact your sales representative for an account.

If your DTU is not connected to S-Miles Cloud, there are three things to check. First, make sure you have correctly entered your WiFi password in the DTU. Second, check that the WiFi network is operational. Finally, your signal strength may be weak. If so, contact your installer.

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

This may indicate an issue with your AC voltage. Contact your installer for more support.

Maximum Power Point Tracking (MPPT) is used to adjust solar installations for the maximum performance in a range of conditions (like the amount of sunlight or temperature).

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.
