Outlines of this Chapter.
Introduce REFUSOL 20K-2T (853P020.200) safety inspection and start
processing.
6.1. Cable Connection Inspection
For first time operation, check the AC voltage and DC
voltage 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.
6.2. 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 REFUSOL
20K-2T (853P020.200) inverter will start automatically. Screen showing “normal”
indicates correct operation.
NOTE 1: Choose the correct country code. (refer to section 7.3 of this manual)
NOTE 2: Different distribution network operators in different countries have different
requirements regarding grid connections of PV grid connected inverters.
Therefore, it's very important to make sure that you have selected the correct
country code according to requirements of local authority. Please consult qualified
