12.
Disconnect all AC and DC connections before working on any circuits associated with the
inverter. Turning the ON/OFF switch on the inverter to off position may not entirely remove
dangerous voltage.
13. Keep the Inverter,Batteries & all cabling away from children.
5. PROTECTION FEATURE
This Inverter is equipped with numerous protection features to ensure safe operation.
Input Low Voltage Protection:
A: When battery voltage is below 10.8V
±
0.2V(for 12V input inverter)/21.6V
±
0.4V(for 24V
input inverter)/ 43.2V
±
0.8V(for 48V input inverter) The
Buzzer will sound 2 times and
RED LED will blink 2 times every eight seconds
, which indicates DC power supply
voltage is descending and batteries need to recharge.
B: When input voltage is below 10.2V
±
0.2V(for 12V input inverter)/20.4V
±
0.4V(for 24V input
inverter)/ 40.8V
±
0.8V(for 48V input inverter),The
Buzzer will sound 3 times and RED
LED will blink 3 times every eight seconds
; AC output will be automatically shut off.
Input Over Voltage Protection
When input voltage reach 15.5V
±
0.2V (for 12V input inverter)/31V
±
0.4V (for 24V input
inverter)/62V
±
0.8V (for 48V input inverter),The
Buzzer will sound 4 times and RED
LED will blink 4 times every eight seconds
; the AC output will be shut off automatically.
Short Circuit Protection
When short circuits occur,
RED LED constantly flashing
; AC output will be shut off.
Overload Protection
When overloads occur,
RED LED constantly flashing
,: AC output will be shut off.
Reverse polarity protection: Fuse and/or MOSfet
a. via Fuse: When battery terminals are reverse connected, fuse(s) will be blown to protect
appliances.
b.via MOSfet(Optional): When battery terminals are reverse connected, the inverter won’t work
until the fault is corrected.
Over Temperature Protection
When heat sink temperature exceeds 45ºC, the inner cooling fan will automatically turn on to cool
the inverter; when Temp drops to less than 30ºC,the inner cooling fan will automatically shut off.
When inner temperature exceeds 75ºC, The
Buzzer will sound 5 times and RED LED
will blink 5 times every eight seconds
; AC output will automatically shut off.
