.

Remark: The solar energy system often works under harsh environmental conditions, such as high temperature and ultraviolet radiation. Therefore, the solar system and photovoltaic array must be

17 / 56

connected using a specialist photovoltaic electric cable as the DC cable.

Caution!

` Regarding the inverter equipped with DC switch, please ensure the switch is in "OFF" position before connecting the inverter with PV panels. Then switch to "ON" when finished connecting job.

` Before connecting the PV panels, please ensure the plug connectors have the correct polarity. Incorrect polarity connection could permanently damage the unit.

` Checks short-circuit current of the PV string. The total short-circuit current of the PV string cannot exceed the inverter’s maximum DC current.

` High voltage exists when the PV panel is exposed to the sun.

Please secure the terminal connection, and do NOT touch any exposed components in case of electric shock.

` If you choose the models without DC switch an external disconnection device should be used. It should be multi-pole switch-disconnector (all poles disconnected simultaneously), which has been approved according to standard IEC/EN 60947-3. The rated current should be between 20A and 25A.

RS485 interface is used for multipoint communication. EzLogger can monitor and communicate with 50 inverters at the same time.

18 / 56

But the maximum length of the cable should not exceed 1000 m. All the inverters, which communicate through one cable, should use provided RS485 interface (a piece of 10# cable is recommend to be connected for waterproofing without RS485 cable connection). The typical inverter connection graph through RS485 is shown below.

Figure 3.4.3-1

The graph below shows the monitoring system connection, in which inverters’ multipoint communication can be realized through RS485 interface. The software ‘EzExplorer’ used in PC end can realize real-time monitoring of 16 EzLoggers at the same time.

This area indicates the flow of energy. Flashing dash lines between the sun and modules and inverter means there is energy walks from the sun to modules and then modules transfer it to inverter. Full line between inverter and the grid means the grid is available but inverter is not yet feeding power at the time. Flashing dashing lines means inverter is feeding power to grid. No line means grid is not available.

In all levels of menu, it will automatically enter the first item of the first level menu if no action is taken within 20S, meanwhile, the modified data will be stored into internal memory.

When PV panel is feeding power to the inverter, the screen shows the first interface of first-level menu.

The interface displays current state of the system. It shows

“Waiting” in the initial state; it shows “Normal” during power generation mode; if there is something wrong with the system, error

39 / 56

message is shown. Please see chapter 4.7 for details.

Press any key once to turn on the LCD backlight when it is off; if the backlight is on, press ‘DOWN’ key to enter the next menu displaying data of Vpv and Ipv; press ‘ENTER’ to lock the current interface.

In the first level menu, the displayed information can be switched through ‘DOWN’ and ‘UP’ key operation, there are 7 interfaces in total, which are circulatory.

The second-level menu can only be selected through ‘ENTER’ from the seventh interface.

In the second-level menu, third-level menu can only be accessed through ‘Histogram’.

4.5 Usual Start and Operation Display

When the input voltage reaches inverter turn-on voltage, LCD starts to work in a second, LCD displays “waiting”. If the grid is accessible,

‘Checking xxxSec’ will be shown up in 3sec, counting down from

30sec, the machine starts self-checking, when it shows “00Sec” you can hear the relay triggered 4 times, LCD displays “Normal” afterwards. The instant power output will be shown at the right bottom of LCD.

The following examples will demonstrate the information display through key operation, given that the default initial menu is set as the first interface of first-level menu.

7. Maintenance

Regular maintenance ensures a long operating life and optimal efficiency of the entire PV plant.

Caution: Before maintains please disconnect the switch on AC and

DC sides. Wait 10 seconds until the residual voltage has been drained.

7.1 Cleaning the Fans

DT series inverter is fitted with two fans on its left side. The fan intakes and handle covers should be cleaned yearly with a vacuum cleaner. For more thorough cleaning, completely remove the fans.

1. Disconnect the switch on AC and DC sides.

2. Wait 10 seconds until the residual voltage has been drained and the fans are no longer turning.

3. Disassembly the out fan assemble (indicated as below figures)

• Loosen the five M4*0.75 screws with a crosshead screwdriver, then remove the fan assemble out the cabinet about 50mm slowly

• Open the lockers of the two fan connectors and remove them from housing, then take the fans assemble away

4. Clean the ventilation grid and the fan with a soft brush, a paint brush, a cloth, or compressed air.

5. Reassembly the out fan assemble into cabinet

7.2 Checking the DC Disconnect

In the case of normal use, the DC Disconnect does not require any maintenance.

It is recommended, though not compulsory, to:

• Check the DC Disconnect regularly.

• Activate the DC Disconnect 10 times in a row once a year.

Operating the switch will clean the contacts and will extend the life of the DC Disconnect.
