Please follow the local grid code and then choose the
corresponding grid standard.
Grid level: there're several voltage levels for the inverter
output voltage when it is in off-grid mode.
LN:230VAC LL:400VAC,LN:240VAC LL:420VAC ,
LN:120VAC LL:208VAC , LN:133VAC LL:230VAC.
IT system: For the IT grid system, the Line voltage
Normal connect: The allowed grid voltage/frequency
range when the inverter first �me connect to the grid.
Normal Ramp rate: It is the startup power ramp.
Reconnect a�er trip: The allowed grid voltage
/frequency range for the inverter connects the grid
a�er the inverter trip from the grid.
Reconnect Ramp rate:It is the reconnec�on power ramp.
Reconnec�on �me: The wai�ng �me period for
the inverter connects the grid again.
PF: Power factor which is used to adjust inverter
reac�ve power.
HV1: Level 1 overvoltage protec�on point;
