FAULT FINDING
1. INVERTER STAYS ON EVEN WHEN NO APPLIANCE IS BEING USED.
This can be a common problem known as a "phantom load", but can be easily overcome with
ENERGY MANAGEMENT. Some appliances will need to be switched off at the power point as they
may still represent a small load despite being switched off at the appliance. Check again to make sure
there are no appliances left on, then sequentially switch off appliances at the wall and by watching your
night light (as described in "Handy Hint" on page 19), check to see if the SA41 returns to pulsing
mode (after a 10 second delay). Once you have found the offending appliance, adjust the sensitivity of
the demand start up (see set parameters) until the inverter turns off. Once this is done re check that
small loads will still bring the inverter on when required.
2. INVERTER WILL NOT COME ON WHEN SMALL APPLIANCE IS SWITCHED ON.
This means that your demand start sensitivity is set too high. With the appliance in question switched
on, adjust the demand start sensitivity until your SA41 turns on. See Demand Start Sense on page 10.

If the heatsink reaches its maximum operating temperature, the SA41 will
shut down to protect itself. The SA41 will come on again only when the
temperature drops to a safe level. The present temperature of the heatsink is
also displayed.
When the Alarm 1 input on the SA41 is activated, (see "Settings" on page
12) this message is displayed and the buzzer sounds. The buzzer will
continue to sound as long as the input is active.
When the Alarm 2 input on the SA41 is activated, (see "Settings" on page
12) this message is displayed and the buzzer sounds. The buzzer will
continue to sound as long as the input is active.
If the battery charge drops below the ‘Min charge’ setting, and the ‘Lo
Chg alarm’ setting is set to ‘ON’ then this alarm will sound. You are then
able to take appropriate action such as removing loads or starting a
generator to prevent further discharge and possible damage to your
b
atteries.
