Step 1 Turn on DC switch.
Step 2 Turn on AC switch.
When the solar arrays generate adequate power, the inverter will startup automatically.
Display showing “normal” indicates correct operation.
Step 3: Choose the correct country code. (refer to section 6.3 of this manual)
Notice: 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 electrical engineer or personnel from electrical safety
authorities about this.
DASS Tech Co., Ltd is not responsible for any consequences arising out of
incorrect country code selection.
If the inverter indicates any other fault, please refer to part 7——error messages for help.
