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 inverte r/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 quali fy 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 the se settings, refer to th e el ec trical rating of conn ected load equipmen t .
Most equipment that is marked with a single voltage (120 VAC, for example) rath er than a
range (110–125 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.
