INSTALLATION
START THE INVERTER To start up the Inverter, it is important that the
following steps are strictly followed:
1. Switch the grid supply main switch (AC) ON first. 2. Switch the DC switch
ON. If the voltage of PV arrays are higher than start up voltage,
the inverter will turn on. The red LED power will light. 3. When both the DC
and the AC sides supply to the inverter, it will be ready to generate
power. Initially, the inverter will check both its internal parameters and the
parameters of the AC grid, to ensure that they are within the acceptable
limits. At the same time, the green LED will flash and the LCD displays the
information of INITIALIZING. 4. After 30-300 seconds (depending on local
requirement), the inverter will start to generate power. The green LED will be
on continually and the LCD displays GENERATING.
WARNING Do not touch the surface when the inverter is operating. It may be hot
and cause burns.
STOP THE INVERTER To stop the inverter, it is mandatory that the steps below
are followed in the exact order outlined.
1. Select “Grid Off” in the Advanced Setting of Inverter LCD. 2. Turn off the
AC Switch between LEDVANCE inverter and Grid. 3. Wait approximately 30 seconds
(during this time, the AC side capacitors are dissipating
energy). If the inverter has DC voltage above the start-up threshold, the red
POWER LED will be lit. Switch the DC switch OFF. 4. Confirm all LED’s switch
OFF (~one (1) minute).
CAUTION Although the inverter DC disconnect switch is in the OFF position and
all the LED’s are OFF, operators must wait five (5) minutes after the DC power
source has been disconnected before opening the inverter cabinet. DC side
capacitors can take up to five (5) minutes to dissipate all stored energy.
