OPERATION
To gain more understanding of these operational notes, it is suggested that they be read in conjunction with hands on access to an inverter with DC power applied.
When you first apply power to the SA41 with default factory settings, the SA41 should be in STANDBY mode. There may be a quiet pulsing sound and the red neons on the power point will flash if turned on. The SA41 is now ready for use with no further adjustments necessary, using the factory settings.
If the display shows TIME, the default settings have been changed, and the day and time will need to be set before the display will return to STATUS.
ENERGY MANAGEMENT
The SA41 incorporates ENERGY MANAGEMENT, which allows you to monitor and control your energy system by displaying information on the Liquid Crystal Display. Settings can be adjusted via the front panel keys.
STATUS
Status : STANDBY
Inverter : OFF
Status : CONT
Inverter : ON
Status : RESET
Inverter : OFF
The first screen will display the Status of the SA41. There are three status conditions: STANDBY, CONT (continuous) and RESET, which are explained in more detail below.
When this screen is displayed, the Status can be changed by pressing the UP or DOWN keys. Each time the UP key is pressed, the status will change from STANDBY to CONT then RESET and back to STANDBY whereas the DOWN key will change the Status in the reverse order.
The second line indicates whether the inverter is ON or OFF, i.e. if there is 240V available or not. During pulsing, OFF is displayed on the second line, reverting to ON when a load is connected and the inverter starts.
The STANDBY mode means that the SA41 is producing pulses of power while waiting for an appliance to be switched on. This is frequently called the “demand start” because as soon as the appliance is operated, the SA41 will turn on and remain on until the appliance is switched off. After a 10 second delay, the SA41 will return to STANDBY mode, awaiting another load.
This feature is extremely important as it conserves valuable battery power when no appliances are on.
CONT mode (continuous) means the inverter will be on at all times regardless of the load. This situation is useful if you have small loads such as VCRs or digital clocks that require 24 hour power, or if loads are too small to be sensed in the STANDBY mode. The only disadvantage is that when no appliances are operating, the SA41 will be drawing more power than it would in STANDBY mode.
RESET mode electronically shuts down the inverter. When placed in this mode, any overload or shutdown conditions are also reset.
