Ø Do not use the equipment if any operating anomalies are found. Avoid temporary repairs. Ø All repairs should be carried out 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.
“The world’s First Daisy-Chain 4 in 1 Unit Microinverter” with extremely wide DC input operating voltage range (16-60V) and low start-up voltage (22V only). Hoymiles 4 in 1 unit Microinverter HME-1000T/1200T/1350T/1500T-AU is the perfect selection for PV system with uneven number of panels with world’s NO.1 CEC weighted efficiency – 96.50% (peak efficiency 96.70%) in 2015.
A) Hang the microinverter on the screw (shown as picture below), and tighten the screw.The silver cover side of the Microinverter should be facing the panel. *Note: Please install the microinverter at least 50cm above the ground/roof for better communication with Hoymiles DTU.

2. If the alarm occurs frequently, check whether the grid frequency change rate change rate is within the acceptable range. If no, contact the local power operator or change the grid frequency change rate limit via Hoymiles monitoring system with the consent of the local power operator. Power grid outage Please check whether there is a power grid outage.
ü Flashing Red and Green alternately: Firmware is corrupted. *Note: All the faults are reported to the DTU, refer to the local APP of the DTU or Hoymiles Monitoring Platform for more information. 6.3 On-site Inspection (For qualified installer only) To troubleshoot an inoperable microinverter, follow the steps in the order shown.
5. Check the DC connections between the microinverter and the PV module. 6. Verify the PV module DC voltage is within the allowable range shown in appendix Technical Data of this manual. 7. If the problem persists, please call Hoymiles customer support. Warning Ø...
Avoid temporary repairs. All repairs should be carried out using only genuine spare parts. If all the microinverters connect to the DTU-Pro, the DTU can limit the output power imbalance of all the microinverters between phases to below 3.68kW if required. Please refer to “Hoymiles Technical Note Limit Phase Balance” for more details.
7.2 Storage and Transportation Hoymiles packages and protects individual components using suitable means to make the transport and subsequent handling easier. Transportation of the equipment, especially by road, must be carried out by suitable ways for protecting the components (in particular, the electronic components) from violent, shocks, humidity, vibration, etc.
An external indication of earth fault alarm can be provided by the connecting the PV System to Hoymiles monitoring app/portal. For details of how to configure monitoring please refer to document “HMP Operating Guide (Webpage) V2.0” and “HMP Operation Guide (APP)”.
DC current. But the maximum short circuit current must be equal to or less than the maximum input DC short circuit current. The output DC power of PV module is NOT recommended to exceed 1.35 times the output AC power of the microinverter. Refer to “Hoymiles Warranty Terms & Conditions” for more information. 8.1 DC Input Model...
