4.2 The LCD Display
The PVI 3000-5300 inverter is supplied ready to operate so there are no settings, which need to be made by the user for fully
automatic feeding of power into the grid. The device comes standard with an LCD display on which various data can be read.
All indicated data is only an indication and has tolerances of up to
5%.
The PVI 3000-5300 inverter has a 16 x 2 LCD to show the operating status, input/output data, and error messages. As long
as the DC input voltage is above the pre-set threshold value, the LCD continues to display the information following the
process flow illustrated in the Figure 4.2.1.
The process flow may follow the
operating mode
,
fault mode
, or
idle mode
. The operating mode is when the system goes
from power-on to
system check
,
monitoring
, and then
grid feeding mode
without any fault condition detected. The inverter
is should work following the operating mode and eventually feeds the power to the grid. During the system check and
monitoring mode, if a fault condition that could be cleared automatically is detected, then the system will go into the fault
mode that the system could return to the operating mode once the fault condition goes away. One obvious example is that an
“island” condition is detected due to the grid going off and then back on later, the fault condition is cleared when the power
returns. If a fault cannot cleared on its own, then the system will enter the idle mode and will need a service person to clear
the fault and reset the system. These three modes are illustrated in the Figure 4.2.1.
The following figures explain how the display works in the
operating mode
.
When the DC input voltage goes above the pre-set threshold value, the inverter is powered up and will show the company
name and model name (PVI 4000 in this example) on the LCD as shown below.
After 3 seconds, software versions of two embedded CPU’s, Sequential and Current controllers, will be displayed on the LCD.
Afterward, the serial number (S/N), the baudrate (BR) / address (ID) for the communication port will be displayed..

And then three (3) seconds later, it displays the setting of the nominal grid voltage configuration. The grid type setting of
208/240 with neutral is used as the display example shown below. For the grid type setting, please refer to section 2.3 Wiring
the Inverter.
