First Commissioning; Led Status - Technaxx TX-203 User Manual

First commissioning

After mechanical and electrical installation of the solar power system, you can put the
system into operation. There should be enough sunshine for this. The solar panels
need to produce at least a start voltage of 22V.
Initial state:
1. The micro inverter is connected to the solar panels (see DC connection)
2. The individual micro inverters are connected to each other on the AC side if you
have more than one (see AC connection)
3. The cables are fixed protected from rain and sunlight
4. The feed line is connected to the mains via a circuit breaker
Proceed as follows:
1. Turn on the circuit breaker and any other switches that may be present.
2. Switch on the main AC switch.
3. The unit LED should begin flashing green after you turn on the AC circuit breaker.
See chapter LED status for more information.
4. The micro inverter starts feeding (grid synchronization) within 2 minutes if there is
sufficient solar radiation. The status LED indicates the basic function. You can check
the feed-in power with a suitable power socket energy meter* (*needs to be water
proof for outside use!).
5. If you have installed a feed-in meter, you can also use it to check the current feed-
in power or energy.
Note: When AC power is applied but the micro inverter is not started, approximately
0.2W of power can be measured for each micro inverter using a power meter. This
power is reactive power, not consumption from the utility grid.

LED status

The LED of each micro inverter provides information about the current status. All micro
inverters draw their supply voltage from the DC connector/solar panels.
Status during power up
The green LED will flash fast a few times. Then switch-on process usually takes up to
2 minutes. Following LED status can occur:
Flashing fast red (1s):
Flashing slow green (3s):
Flashing fast green (1s):
No LED Flashing/LED off:
No AC connection
AC connection &
DC connection voltage lower 22V
AC connection &
DC connection voltage over 22V
No DC connection/solar panels
connected
