Problem
The fan turns on and off
during inverter mode.
Battery charging current is
lower than the charging set
point during bulk charge
mode.

Resistive Loads

Possible Cause
The inverter is running
continuously at high
power.
Ambient (environment)
temperature is high.
Alarm is turned OFF.
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.
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.
Solution
Do not be alarmed, the unit is performing
normally. The fan is activated
automatically.
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.
Press and hold the Select button for two
seconds to disable (or enable) the audible
alarm. See "Display Panel Operation" on
page 4–2.
