About Function

Work Mode

Normal: In this mode, the microinverter operates normally and converts DC power into AC power to support the household loads and feeds into the public grid.

Zero Export Control : In this mode, the microinverter’s generation is limited based on the current household loads, and there is no extra power fed into the public grid.

Standby: There are several circumstances in which the microinverter will be  in Standby mode:

• The current condition contradicts with the microinverter operating requirements.
• No household loads or the export control value has been set as “0” on the DTU in the Zero Export Control mode.

About Installation

Accessories

*Note: All accessories listed above are not included in the package, and need to be purchased separately. Please contact our sales representative for pricing information. (M8 screws need to be prepared by installer-self.)

Installation Precautions

Please install the microinverter and all DC connections under the PV module to avoid direct sunlight, rain exposure, snow pile-up, UV, etc. Allow a minimum of 2 cm of space around the microinverter enclosure to ensure ventilation and heat dissipation.

*Note: For some countries, the DTU will be required to meet local grid regulations (e.g. G98/99 for UK).

Required Space Distance

If the microinverters are installed on a concrete roof or steel roof, their communication with the DTU may be slightly affected. Under such installation conditions, it is better for the microinverters to be installed 50 cm above the roof. Otherwise, more DTUs may be required to ensure communication quality between the DTUs and the microinverters.

Grounding Considerations

This microinverter is a Class I equipment with a basic isolation transformer, and this microinverter must be earthed. There is an earth wire inside the AC cable, so usually grounding can be done by directly using this wire. If the utility has any special requirements, grounding can be done by affixing the mounting bracket to the racking.

Preparation

Installation of this equipment is carried out based on the system design and the place in which the equipment is installed.

• Installation must be carried out with the equipment disconnected from the grid (power disconnect switch on) and with the PV modules shaded or isolated.
• Refer to the Technical Data to ensure that the environmental conditions fit the requirements of the microinverter (degree of protection, temperature, humidity, altitude, etc.)
• To avoid power de-rating due to an increase in the internal temperature  of the microinverter, do notexpose it to direct sunlight.
• To avoid overheating, always make sure that the air flow around the microinverter is not blocked.
• Do not install in places where gases or flammable substances may be present.
• Avoid electromagnetic interference that can compromise the correct operation of electronic equipment.

When choosing the installation position, comply with the following conditions:

• Only install on structures specifically conceived for PV modules (supplied by installation technicians).
• Install the microinverter underneath the PV modules to make sure that it operates in a shaded or shadowed environment. If this condition cannot be met, it maytrigger the microinverter production derating.

Insulation Resistance Detection

There is a resistance sensor in the microinverter to measure the resistance between the outputs of PV module and the ground. If there is a problem with PV module insulation, DC wiring or connectors of the module and so on, the resistance between the outputs of the module and the ground may decrease. If this resistance drops below a preset threshold, the microinverter will stop producing power and report this ground fault. This fault will persist until it is cleared on the S-Miles Cloud (Hoymiles Monitoring Platform). This fault will persist until the microinverter is rebooted.

Please note that this fault cannot be cleared if the cause of the failure is still present. If the fault persists, contact your installer or Hoymiles for possible replacement.
