are within the acceptable range
Attention
AC grid connection
Use multimeter to confirm that three lines and PE line are connect correctly. DC
pv connection
Use multimeter to confirm that positive pole and negative pole of PV strings,
and the Voc of each string is lower than the inverter max DC input.
5.2. Start Inverter
Step 1:
Turn ON the DC switch.
Step 2:
Turn ON the AC circuit breaker.
When the DC power generated by the solar array is enough, the SOFAR
3.3~12KTLX-G3 inverter will start automatically. Screen showing “normal”
indicates correct operation.
NOTE 1:
Choose the correct country code. (refer to section 6.3 of this manual)
NOTE 2:
Different distribution network operators in different countries have different requirements
