Setting value for surge protection U>> in [V]

"Overvoltage Time U>>"

Setting value of time for surge protection U>> in [s]

"Long Time Average Limit"

This function calculates a moving average voltage value over the set time and
compares it with the set overvoltage protection value. If the overvoltage protec-
tion value is exceeded, a disconnect occurs.

Parameter

Description

"Long Time Average
Limit"

Activate / deactivate the voltage average limit value
"On" / "Off"

"Overvoltage Averaging
Time U>"

Time period over which the average value is calcu-
lated in [s]. (If 0 s is set, the check is not active)

"Overvoltage U>"

Setting value of the surge protection with average
value formation U> in [V]

"Fast Overvoltage Disconnect"

Fast overvoltage disconnect for voltage spikes that can respond within one peri-
od.

Parameter

Description

"Fast Overvoltage Dis-
connect"

Activate / deactivate fast RMS overvoltage discon-
nect (exceeding 135 % of rated voltage) "On" / "Off"

"Fast Overvoltage Dis-
connect Time"

Setting value of time for fast surge protection (peak
value exceeded by 35 %) in [s]. This disconnect can
be configured in the time range of microseconds.

"Startup and Reconnection"

Before the inverter is allowed to connect, the connection conditions for voltage
