losses and cause malfunction of the 
inverter. 
Once the inverter is connected to the 
batteries, a 230 V voltage is present in 
the outlet of the inverter. 

Control and indicators 
Control switch on/off 
There is a switch on the inverter to 
activate or deactivate it. Use this function 
to save the energy of the batteries when 
you are not using the inverter. 
Green indicator 
A green light on the inverter indicates its 
function mode: 
Illuminated

: a 230 V voltage is present in 

the outlet, the inverter is on. 

: 

_  _  _ : No load (stand-by) 
__ __ __ : the 230 V voltage has been 
cut due to an alarm; the inverter will 
resume function when the failure has 
disappeared (see the failure table). 

: the 230 V voltage is NOT present in 

the outlet, the inverter is off. 

Acoustic indicator 
The AJ inverter has an acoustic indicator 
for the following instances: 
Intermittent beep

: there is a failure in the 

inverter and the outlet voltage will be 
interrupted. 
Possible failures: 
Overheat: the acoustic indicator beeps 3 

ºC before cutting the tension. If the 
temperature reaches its normal level, 
the voltage in the outlet is not 
interrupted. 

Low battery voltage: the indicator beeps 

for a minute before the interruption. If 
the voltage of the battery rises, the 
outlet voltage is not interrupted. 

 

have pressed the ON/OFF switch to 
restart the inverter. The tension in the 
outlet will be immediately present after 
the acoustic signal. 

The inverters from the AJ 500-12 are 
equipped with a stand-by system which 
is in function when no load is 
connected. In that situation the inverter 
is in low power consumption mode. 
The output tension is not continuously 
present and the LED is blinking as long 
as no load is detected. 
The minimal load detected can be 
adjusted between 1 and 20 W. In most 
cases this adjustment is not 
necessary

. This adjustment is made 

with a small screw driver in the hole 
marked stand-by. This adjustment is 
made with a small screw driver in the 
hole marked stand-by. Adjusting the 
switching-on level is as follows: Switch 
off all consuming devices; turn the 
Turning Knob to the Left (counter-
clockwise)until the LED is blinking, 
switch ON the smallest consuming 
device (i.e. Mobile phone charger); turn 
the Turning Knob slowly to the right 
until LED is lit continuously. Check that 
the inverter will go back in stand-by 
mode when you remove the load. If 
not, this means that the load is too 
small to be detected. 
If the stand-by is not required, turn the 
Knob fully to the right.  
 In the full counter clockwise position, 
the sensibility is minimal (20 W). Do 
not push on the screw driver. 
NOTE: in this mode the output voltage 
is intermittently present at the output
