Microinverter Read This First Dear customer, thank you for choosing the microinverter from TSUN. We hope you will find our products meet your needs for renewable energy. Meantime, we appreciate your feedback regarding our products. A solar microinverter, or simply microinverter, is a plug-and-play device used in photovoltaics, that converts direct current (DC) generated by a single solar module to alternating current (AC).
The microinverter is used in grid-tied applications, comprised of two key elements: Microinverter. TSUN monitoring system. The microinverter converts the DC electricity generated by solar panels into AC electricity which is in accordance with the requirements of the public grid and sends the AC into the grid, reducing the load pressure of the grid.

Pre-installation Check Check the Package Although TSUN’s microinverters have surpassed stringent testing and are checked before they leave the factory, it is uncertain that the microinverters may suffer damage during transportation. Please check the package for any obvious signs of damage, and if such evidence is present, do not open the package and contact your dealer as soon as possible.

Microinverter Step 1. Fix the microinverter. DANGER ·Do not install the equipment in adverse environmental conditions such as flammable, explosive, corrosive, extremely high or low temperature, and humid. WARNING ·Choose the installation location carefully and adhere to specified cooling requirements. Micro-inverter should be installed in a suitable position with good ventilation and no direct sunshine.

Microinverter Step 2. Connect the ground cable WARNING ·Ensure that all the microinverters are well grounded. ·Use ɸ6 screw for the ground port. Connect the ground cable to the enclosure of the microinverter. Step 3. Connect the AC cable of two microinverters WARNING ·According to the max current of the AC cables, there is a max installation quantity for the micro-inverter in each cable section.
Page 13
Microinverter Use Nylon cable ties to fix the AC cables onto the frame. Use a Connector Protective Cap to make sure the unused AC connector to be closed. Step 4. Connect the AC end cable of each cable section DANGER ·Do not install the AC junction box without first removing AC power from the system.

Microinverter Step 6. Make an installation map CAUTION ·If there is more than one installation site, please make the installation map separately and give a clear description of the installation site. ·The row of the table corresponds to the shorter side of the PV module and the column of the table corresponds to the longer side of the PV module.
(input port) to cease the output of active power or limit active power to a regulated level. This logic input can be the RS485 port, Ethernet port, and so on. TSUN microinverter provides an extra power control device that contains an RS485 port for this remote active power control. For more information, refer to the “User Manual of TSUN power control device”.
Check the voltage of the PV module and make sure that the PV1VoltOver_Fault below the maximum DC input voltage of the voltage is microinverter. If this fault appears continuously, please contact the TSUN PV2VoltOver_Fault service. This warning mostly appears in the morning or at dusk. It’s PV1VoltLow_Fault normal and will disappear automatically.
Microinverter Maintenance Guide Routine Maintenance Only authorized personnel are allowed to carry out the maintenance operations and are responsible for reporting any anomalies. Always use the personal protective equipment provided by the employer when carrying out maintenance. During normal operation, check that the environmental and logistic conditions are appropriate. 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.
Microinverter Recycling and Disposal This device should not be disposed of as residential waste. A Microinverter that has reached the end of its life is not required to be returned to the dealer. Users must find an approved collection and recycling facility in the area.
Within the warranty period of the microinverter, the invoice and date of purchase are required for the service. Besides, the trademark on the product should be visible, otherwise, warranty is not available. More information can be found in TSUN Warranty Policy. V1.0...
