Inverter Applications
The
Freedom HF
performs differently depending on the AC loads
connected to it. If you are having problems with any of your loads, read
this section.
Resistive Loads
These are the loads that the inverter finds the simplest and most efficient
to drive. Voltage and current are in phase (i.e. in step with one another).
Resistive loads usually generate heat in order to accomplish their tasks.
Toasters, coffee pots, and incandescent lights are typical resistive loads. It
is usually impractical to run larger resistive loads—such as electric stoves
and water heaters—from an inverter due to their high current
requirements. Even though the inverter can most likely accommodate the
load, the size of battery bank required would be impractical if the load is
to be run for long periods.
The fan turns on and off
during inverter mode.
The inverter is running
continuously at high
power.
Do not be alarmed, the unit is performing
normally. The fan is activated
automatically.
Battery charging current is
lower than the charging set
point during bulk charge
mode.
Ambient (environment)
temperature is high.
Do not be alarmed, the unit is performing
normally. The charging current
automatically de-rates at high ambient
temperature.
Improve ventilation. Make sure the unit’s
ventilation openings are not blocked.
Alarm does not sound when
an error is encountered.
Alarm is turned OFF.
Press and hold the Select button for two
seconds to disable (or enable) the audible
alarm. See
“Display Panel Operation” on
