Configuration

Cfg AC Limits (Configure AC Limits)
Lo AC Volt
Full name Low AC Transfer voltage (AC under voltage level)
Configurable setting Low AC Transfer voltage is the voltage below which the inverter/charger no
longer qualifies AC as good, opens the relay, and attempts to transfer to Invert
mode if Invert is enabled.
When to use This setting lets you adjust the AC parameters when AC supply is outside of the
lower voltage range required for electrical equipment.
Outcome The lower level of voltage that will be accepted as good by the inverter/charger
can be varied.
Lo AC Freq
Full name Low AC transfer frequency (AC under frequency level)
Configurable setting This setting lets you adjust the frequency at which the inverter/charger no longer
qualifies AC as good and attempts to transfer to invert mode.
When to use This setting lets you adjust the AC parameters when the AC supply is outside the
lower frequency range required for electrical equipment.
CAUTION: Risk of damage to equipment
The following configuration settings adjust the quality of the AC input source that the
inverter/charger will qualify and pass through to your AC loads. Voltage or frequency that
is too high or too low for a particular piece of load equipment may cause damage to that
load.
Before adjusting these settings, refer to the electrical rating of connected load equipment.
Most equipment that is marked with a single voltage (120 VAC, for example) rather than a
range (110125 VAC) can be expected to run properly over the range of 108 VAC to 125
VAC, since this is the normal operating range of electrical utilities.
Lo AC Volt [90.0V]
Range of values Increment Default
85 to 110 VAC 1 volt 90 VAC
Lo AC Freq [55Hz]
Range of values Increment Default
55 to 58 Hz 1 Hz 55 Hz
