7 Turning The Pv Inverter On/Off; Start-Up Procedures; Dc Voltage Checking; Ac Utility Voltage Checking - Delta H5E 220 Operation And Installation Manual

7 Turning the PV inverter on/off
The internal temperature may exceed over 70°C while operating.
To avoid injury, do not touch the surface of the inverter whilst the unit is
in operation.
After installation, please ensure the AC, the DC and communication
connection are correct. When enough power is generated from the PV
array, the device will operate automatically and will initial 'self-test'.
This self-test takes approximately 2 minutes and will occur at first start-up
of the day.
When undertaking Battery wiring, please ensure that the BX6.3_DD system is
shutdown.

7.1 Start-up Procedures

7.1.1 DC Voltage Checking

Firstly, uncover the PV arrays and expose them to full sunlight. Please note, the
sunlight must be intense enough to produce the required output voltage for the
inverter to start up.
Measure the PV array open circuit DC voltage across the DC positive (+) and
negative (-) terminals.

7.1.2 AC Utility Voltage Checking

Using an AC voltmeter, measure the AC open circuit utility voltage between L1 (L)
and L2 (N) Ensure the voltage is at approximately the nominal value. The inverter
operates with a line-to-line voltage range around the nominal value.
Refer to Chapter 11 output section for the utility voltage operating range for the
inverter model.
