Configuration
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.
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.
Lo AC Freq
Full name Low AC transfer frequency (AC under frequency level)
Configurable setting This setting lets you adjust the lowest frequency at
which the inverter/charger no longer qualifies AC as “good” and attempts to
transfer to invert mode.
You can adjust Lo AC Freq settings as follows:
When to use This setting can be used when the AC supply frequency is
lower than the set value required for the electrical equipment.
Outcome The lower frequency of the AC supply above which it will be
qualified as “good” by the inverter/charger can be varied.
Hi AC Volt
Full name High AC transfer voltage (AC over voltage level)
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.
Failure to follow these instructions can damage the unit and/or
damage other equipment.
