user’s manual inverter SE3.3Ni - SE3.8Ni - SE4.6Ni
DC power generated by the PV array to the AC power that is then fed into the grid. The inverter may stop feeding the power and go back to
monitoring mode once any condition for grid feeding mode is found not fulfilled.
Fault :
When fault(s) occurs and been detected in the operating mode described above, the inverter will terminate the present state, stop feeding
power to the grid, and then jump into the fault mode that executes preset sequence. When the faults have been cleared for certain period of
time, the inverter will leave fault mode and enter system check mode. Some faults, like component failure, will cause the inverter go into the
idle mode that will need service staff to clean the errors.
Idle :
Once the inverter jumps into this operating mode, the inverter has detected a malfunction of the ENS and has stopped feeding the power to
the grid for safety reason. Normally this is a failure that can not be removed on field. It needs service personnel coming to remove the problems
and put the system back to operation.
3.2 Operation Feature
1. FLEX-MPPTs :
Through the FLEX-MPPTs feature, the SE inverters may manage the PV strings in either the independent mode or the master/slave mode or
both. The SE inverter is designed to support up to three independent PV strings. If each PV string is exposed and obtains the sun light enough
to generate DC power and the DC voltages are different, then it is prefer to select independent mode that each PV string is tracked by its own
MPPT. If any two or all three PV strings may be able to get same intensity of the sunshine and generate the same DC voltage, users can then,
through the internal jumper (see Figure 3.2.1), select the Master/Slave mode that any two PV or all three PV strings can be connected in
