y0.28
UPS voltage lower limit
0.0～200.0%
Default: 70.0%
Used for setting UPS power voltage lower limit, when inverter is detecting light load direction,
UPS power voltage is lower than the setting of y0.28, inverter will change to detect reverse direction
y0.29
UPS voltage lower limit error
0：Invalid
Default: 1
1：Valid
