!

CAUTION!

R

ISK OF LETHAL ELECTRIC SHOCK

.

It is admitted to work on the PV Inverter only after switching the relative power sources.

The VDE regulations must be followed:

Disconnect

Ensure that the device cannot be reconnected

Ensure that no voltage is present

Ground and short-circuit the unit if necessary (not on the DC side)

If necessary, cover or shield any adjacent live components

The following power sources must be isolated:

Grid voltage for grid feeding

Grid voltage for internal power supply (optional)

DC voltage from the photovoltaic generator

Simply switching off the main AC and DC switches is not sufficient to ensure proper isolation of the device. The main switches only separate the power circuit from the grid and the photovoltaic generator.

!

CAUTION!

R

Dangerous accidental-contact voltages can be present in the PV Inverter even when the main AC and DC switches are switched off!

Wait at least 5 minutes after switching off the PV Inverter.

ISCONNECTING

The DC voltage is isolated using the internal or external DC input fuses, or using an external circuit breaker if present. Isolation by removing the DC input fuses must occur under load-free conditions.

The device contains capacitors on the AC and DC sides that must discharge once the device has been switched off. After switching off, dangerous accidental-contact voltages remain within the device for several minutes. If there is a fault in the device, these voltages may also be present for a longer period of time. Wait at least 5 minutes after switching off the device before opening the device.

5.7. First Time Powering Up

5.7.1. Before Powering Up

1. Check the PV array.

Note:

The PV array open circuit DC voltage must be greater than 500Vdc and less than

1000Vdc.

a. Measure the PV array open circuit DC voltage across the DC positive (+) and negative (-) terminals in DC distribution.

2. Check the AC utility voltage.

Use an AC voltmeter to measure the AC utility voltage. The voltage level should be at the nominal value of 270 Vac Line-Line.

5.7.2. Powering Up the Inverter and Self-test

1. Configure the PV inverter settings.

To provide power to the inverter, switch on the DC switch. The LCD display would be worked normally after 40seconds.

a. For the first time start-up, the Select Country screen is displayed. Highlight a country in the list by pressing the up  or down  buttons and press

ENT to select or EXIT to cancel.

b. Verify the language you selected is correct by pressing ENT for Yes or EXIT for No. Select No to return to the previous screen.

c. The Select Language screen is displayed. Highlight a language by pressing the up  or down  buttons and press ENT to select or EXIT to cancel and return to the first screen.

d. The Main Menu screen is displayed. Highlight E-Today by pressing the up

 or down  buttons and press ENT to select or EXIT to cancel. e. The E-Today screen is displayed while the inverter performs a self-test. If the self-test passes. the System Boot Countdown screen is displayed. If the self-test fails, the test is performed again .

f. The System Boot Countdown screen is displayed and the countdown begins. Press EXIT to return to the Main Menu screen.

g. The Main Menu screen is displayed. Highlight Power Meter by pressing the up  or down  buttons and press ENT to select.

Insulation

Inverter will meansure the impedance between Array and PE before connect to grid. If the impedance between Array and PE is lower then the value that set in Insulation

Settings, inverter will stop connecting to grid. There are 4 modes users can select in

Insulation settings: ON, Positive Ground, Negative Ground, or Disable. Installer can also select different impedance according to the actual situation.
