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.
You can adjust Lo AC Volt settings as follows:
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.
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 (110–125 VAC) can be expected to run properly
over the range of 108 VAC to 125 VAC, since this is the normal supply range of
electrical utilities.
