PV module, consequently improving the flexibility and reliability of the system About the Manual This manual contains important instructions for the MI-600/MI-700/MI-800 Microinverter and must be read in its entirety before installing or commissioning the equipment. For safety purposes, only a qualified technician who has received training or has demonstrated competence may install and maintain this microinverter under the guidance of this document.
• Do not use the equipment if any anomalies are discovered while operating. Avoid temporary repairs. • All repairs should be carried out by using only qualified spare parts, which must be installed in accordance with their intended use and by a licensed contractor or authorized Hoymiles service representative.
“Daisy-Chain 2-in-1 Unit Microinverter” with wide DC input operating voltage range (16 V–60 V) and low start-up voltage (22 V only). The Hoymiles 2-in-1 Unit Microinverter MI-600/MI-700/MI-800 is a reliable solution for PV systems with an uneven number of panels, and offers high CEC weighted efficiency – 96.50% (peak efficiency 96.70%) in 2015.
“1040xxxxxxxx” and “1041xxxxxxxx”, please refer to Section 6.2 and Section 6.4. *Note: The 3rd generation of this microinverter (SN: 1042xxxxxxxx) can only work with the new Hoymiles DTU, DTU-Pro (SN: 10F7xxxxxxxx, 10F8xxxxxxxx, 10FBxxxxxxxx), DTU-G100 (SN: 10D2xxxxxxxx), DTU-W100 (SN: 10D3xxxxxxxx) and DTU-Lite (SN: 10D6xxxxxxxx).

3. If the alarm still exists, contact your dealer or Hoymiles Technical Service Center. 1. Please make sure that the PV module open-circuit voltage is less than or equal to the maximum input voltage.
Alarm Name Suggestion 1. Please check if the microinverter works normally. 2. Check the communication status between the DTU and Hoymiles Monitoring System, or between the DTU and the microinverter. Try to Offline make improvements if the communication is poor.

Island detected station, contact the local power operator to check whether there is a grid island. 3. If the alarm still exists, contact your dealer or Hoymiles Technical Service Center. 1. If the alarm occurs accidentally and the microinverter can still function normally, no special treatment is required.
(3) Other Status • Alternating red and green flashing: Firmware is corrupted. *Note: All faults are reported to the DTU, refer to the local DTU app or S-Miles Cloud (Hoymiles Monitoring Platform) for more information. Status LED Indicator (SN: 1040xxxxxxxx, 1041xxxxxxxx) The LED flashes six times at startup.
Avoid temporary repairs. All repairs should be carried out by using only genuine spare parts. If all microinverters connect to the DTU-Pro, the DTU can limit the output power imbalance of all microinverters between phases to below 3.68 kW if required. Please refer to the “Hoymiles Technical Note Limit Phase Balance” for more details.
Storage and Transportation Hoymiles packages and protects individual components by using suitable means to facilitate the transport and subsequent handling. Transportation of the equipment, especially by road, must be carried out by using means that are suitable for protecting the components (in particular, the electronic components) from violence, shocks, humidity, vibration, etc.
DC short-circuit current. The output DC power of the PV module is NOT recommended to exceed 1.35 times the output AC power of the microinverter. Refer to the “Hoymiles Warranty Terms & Conditions” for more information.
