About Microinverter

This system is composed of a group of Microinverters that convert direct current (DC) into alternating current (AC) and feeds it into the public grid. The system is designed for the incorporation of one Microinverter for two photovoltaic modules. Each Microinverter works independently that guarantees the maximum power generation of each photovoltaic module. This setup enables user to control the production of a single photovoltaic module directly, consequently improving the flexibility and reliability of the system

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

5.2 Installation Precaution

Please install the Microinverter and all DC connections under the PV module to avoiding direct sunlight, rain exposure, snow layup, UV etc. Allow a minimum of 2 cm of space around the microinverter enclosure.

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

5.3 Space Distance Required

Please install the Microinverter at least 50cm above the ground/roof for better communication with Hoymiles DTU. Please contact with Hoymiles technical engineer if there is any special circumstance.

5.4 Preparation

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

The installation must be carried out with the equipment disconnected from the grid (power

disconnect switch open) and with the photovoltaic modules shaded or isolated.

Referring to the Technical Data to make sure the environmental conditions fit the microinverter's requirement (degree of protection, temperature, humidity, altitude, etc.)
To avoid power de-rating due to an increase in the microinverter internal temperature, do not expose it to direct sunlight.
To avoid overheating, always make sure the air flow around the inverter is not blocked.
Do not install in places where gasses or flammable substances may be present.
Avoid electromagnetic interference that can compromise the correct operation of electronic equipment.

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

Install only on structures specifically conceived for photovoltaic modules (supplied by installation technicians).
Install Microinverter underneath of the photovoltaic modules to make sure it works in theshadow. If this condition cannot be met, might trigger the inverter production de-rating.

6.3 On-site Inspection (For qualified installer only)

To troubleshoot an inoperable microinverter, follow the steps in the order shown.

1. Verify the utility voltage and frequency are within ranges shown in the in appendix Technical Data of this microinverter.
2. Check the connection to the utility grid. Verify utility power is present at the inverter in question by removing AC, then DC power. Never disconnect the DC wires while the microinverter is producing power. Re-connect the DC module connectors and watch for five short LED flashes.
3. Check the AC branch circuit interconnection between all the microinverters. Verify each inverter is energized by the utility grid as described in the previous step.
4. Make sure that any AC breaker are functioning properly and are closed.
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

Do not try to repair the microinverter. If the troubleshooting fails, please return it to the factory for replacement.

6.4 Routine Maintenance

1. Only authorized personnel are allowed to carry out the maintenance operations and are responsible to report any anomalies.
2. Always use the personal protective equipment provided by the employer when carry out the maintenance operation.
3. During normal operation, check that the environmental and logistic conditions are correct. Make sure that the conditions have not changed over time and that the equipment is not exposed to adverse weather conditions and has not been covered with foreign bodies.
4. DO NOT use the equipment if any problems are found, and restore the normal conditions after the fault removed.
5. Conduct an annual inspection on various components, and clean the equipment with a vacuum cleaner or special brushes.

Do not attempt to dismantle the Microinverter or make any internal repairs! In order to preserving the integrity of safety and insulation, the Microinverters are not designed to allow internal repairs!

The AC output wiring harness (AC drop cable on the Microinverter) cannot be replaced. If the cord is damaged the equipment should be scrapped.

Maintenance operations must be carried out with the equipment disconnected from the grid (power switch open) and the photovoltaic modules obscured or isolated, unless otherwise indicated.

For cleaning, do not use rags made of filamentary material or corrosive products that may corrode parts of the equipment or generate electrostatic charges.

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.

Each branch should provide a circuit breaker, but no need for central protection unit.

6.5 Replace Microinverter

a. How to remove the Microinverter.

De-energize the AC branch circuit breaker.

Remove the PV panel from the racking, and cover the panel.

Using a meter to measure and make sure there is no current flowing in the DC wires between panel and microinverter.

Use the DC disconnect tool to remove the DC connectors.
Use the AC disconnect tool to remove the AC connectors.
Un-screw the fixing screw on the top of the microinverter and remove the microinverter from the PV racking.

b. How to replace the Microinverter:

Please record down the new Microinverter's SN.
Please make sure the AC branch circuit breaker if off, and following the Microinverter installation steps to install the replacement unit.
Go to the monitoring platform (if customer already register this station online), please access the "Device List" page and find the device that you just replaced. Please click the down arrow next to the "More" on the right side of the page, and select "Replace". Input the new Microinverter's SN and click "Ok" to complete the station changes.

7. Decommissions

7.1 Decommissions

Disconnect the inverter from DC input and AC output; remove all connection cable from the Microinverter; remove the Microinverter from the frame.

Please pack the Microinverter with the original packaging, or use the carton box that can afford 5kg weight and can be fully closed if the original packaging is no longer available.

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. Please dispose the packaging elements in appropriate ways to avoid unforeseen injury.

It is the customer's responsibility to examine the condition of the components transported. Once receiving the Microinverter, it is necessary to check the container for any external damage and verify receipt of all items. Call the delivering carrier immediately if damage or shortage is detected. If inspection reveals damage to the inverter, contact the supplier, or authorized distributor for a repair/return determination and instructions regarding the process.

The microinverter storage temperature is -40 - 85^

7.3 Disposal

• If the equipment is not used immediately or is stored for long periods, check that it is correctly packed. The equipment must be stored in well-ventilated indoor areas that do not have characteristics that might damage the components of the equipment.
  Take a complete inspection when restarting after a long time or prolonged stop.
• Please dispose the equipment properly after scrapping, which are potentially harmful to the environment, in accordance with the regulations in force in the country of installation.
