Inverter Operation - Latronics PV Edge Grid Connect Instruction Manual

When the Inverter is switched on all 4 LED'S light up for 1 second while the
microprocessor performs a start up and system check procedure.
100% Light (Overload)
This light illuminates when the power level
is between 75% - 100%. This light also
indicates overtemp/overload. In this mode
the lower lights will be OFF and this light
will flash.
75% Light (AC Grid)
This light will be ON when the power level is
between 50% -75%.
This light also has 2 other modes of
operation.
When in either of these 2 modes the bottom
light will be OFF.
This light will be ON when the solar input is
present and the AC grid is disconnected
and/or awaiting reconnection.
This light will FLASH for 90 seconds when
the inverter initially connects to the AC grid
and performs a voltage and frequency
stability check before feeding power into the
AC grid.
50% Light (AC Fault)
This light will be ON when the power level
is between 25% - 50%. When an AC fault
is present this light will FLASH and the
bottom light will be OFF.
25% Light
This light will be ON when the power level
is between 0% - 25% or it will flash during
a battery maintenance cycle (see pg12).

INVERTER OPERATION

Indicator Lamps
The 4 lights on the front panel indicate the
Inverter power level in increments of 25%
LED 4 -100% (top Led).
LED 3 - 75%.
LED 2 - 50%.
LED 1 - 25%. (Bottom Led).
If the Inverter were supplying 60% of
Full power then Led's 1, 2 & 3 would be illuminated.
Power from Solar Panels or
If the temperature inside the
Inverter reaches preset levels, the
variable speed fan will switch on
initially in low speed and then into
higher speed if the temperature
continues to increase. Obstruction
of the air intake and output will
reduce the power rating of the
