In this mode, single or multiple microinverters communicate with the S-Miles platform via Wi-Fi. You need to have a Hoymiles account and create an online power plant. You can view the performance of all devices under your plant by connecting the microinverter to the platform via a router.
HMS Extension Connector NOTE Hoymiles doesn’t offer the AC cable and mounting bracket for sale. You need to buy them separately. When purchasing them, ensure compliance with local regulations and consider the following guidelines: • AC cable: Ensure it meets the necessary requirements.
• Plug-and-Play Configuration: In this setup, you should order an HMS Plug and Play Cable from Hoymiles. One end of the HMS Plug and Play Cable directly connects to the microinverter, while the other end plugs into the socket. This configuration ensures simple and convenient installation without requiring additional stripping and crimping operation.
9 N·m. Do not over-torque. NOTICE Due to the on-site conditions of the roof and the placement of the microinverter, you may need additional DC Extension Cables. You can purchase them from Hoymiles by emailing sales@hoymiles.com. Assembly Diagram [A]: HMS Sealing Cap...

If you need to space microinverters farther apart due to an obstacle, Hoymiles offers two solutions: • Using a longer HMS Connection Cable: Hoymiles offers cable lengths of 1.1 m, 2.0 m, 2.3 m, 3.0 m, and 4.6 m. If you require a different length, contact our sales team by emailing sales@hoymiles.com.
This method is ideal for multi-microinverter systems. To enable remote access, you need to connect the mi- croinverter to the S-Miles Cloud via a router. Once you log in to your Hoymiles account and create an online power plant, you can monitor the perfor- mance of the entire plant from anywhere, at any time.

1. Ensure the PV module's open-circuit voltage is less than or equal to the maximum input voltage. PV-1 input overvoltage 2. If it is within the normal range, contact your dealer or Hoymiles technical support. 1. Ensure the PV module's open-circuit voltage is not lower than the minimum input voltage.
E) Reconnect the AC power. F) If DC and AC connections are normal, the LED indicator will flash green five times. G) If the problem persists, contact the Hoymiles Technical Support Team at service@hoymiles.com. Maintenance Regular inverter maintenance is essential for ensuring longevity and optimal performance assets. The checklist provides specific tasks for the maintenance process.
• Disposal of the microinverter must comply with the related local regulations to avoid pollution. The microin- verter must not be disposed of with normal waste. • Do not make repairs yourself. Hoymiles microinverter does not have any user-serviceable parts inside. 7.1 Removing the Microinverter Procedure Step 1: Switch all AC circuit breakers to the OFF position.
Technical Data Technical Data WARNING! Be sure to verify the following before installing Hoymiles Microinverter System. • Verify that the PV module voltage and current specifications are compatible with the microinverter. ▷ Make sure that the maximum open circuit voltage of the PV module is within the microinverter’s operating voltage range.
