About Function

4.1 Work Mode
Normal: In this mode, the microinverter operates normally and converts DC power into AC power to support the household loads and feed 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 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

5.1 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.)

5.2 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 the UK).

5.3 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.

5.4 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.

5.5 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 not expose it to direct sunlight.
• To avoid overheating, always make sure that the airflow around the microinverter is not blocked.
• Do not install in places where gases or flammable substances may be present.
