WARNING! Do not place any items on the inverter during operation. Do not touch the heat sink when
the inverter is operating, as some parts may be hot and cause burns.
The incoming voltage must not exceed the maximum values shown in the technical data in order to
prevent damage to the equipment. Consult technical data table in the Appendix for further details.
Start-up procedure:
1) Set the AC disconnect switch (external or part of switchbox depending on version) to the inverter
to ON.
2) Set the inverter’s DC disconnect switch (external or part of switchbox version) to ON.
3) Once both switches are closed, the inverter starts the grid connection sequence.
• The check routine may take from 30 seconds up to several minutes, depending on grid condition.
• The routine is indicated by the flashing green LED marked POWER.
• Three screens are shown on the display during the check routine:
a) Measuring isolation resistance: “Measuring Riso…” , connection in progress with progress indication.
b) Grid voltage value and status compared to specified values (within/outside range).
c) Grid frequency value and status compared to specified values (within/outside range).
4) When the connection sequence is completed,
the inverter starts operating.
• Normal operation is indicated by a warning sound and the green LED staying permanently ON, (sunlight is
sufficient to export power to the grid).
• If the check routine gives a negative result, the inverter will repeat the procedure until all grid voltage and
frequency parameters and grid configuration are found to be in the specified range.
• During this process, the green LED will keep flashing.

onnection of system to the grid
The two-line Liquid Crystal Display (LCD) is located on the front panel and shows:
• Inverter operating status and statistics;
• Service messages for operator;
• Error messages and fault indications.
During regular operation, the display will cycle through available data. The display changes to
a different screen every 5 seconds or screens may be scrolled manually by pressing the UP
and DOWN buttons located to the right of the display.
1) The following screen is displayed upon inverter start-up:
