Function Introduction
Inverter output function: Open the switch of the front panel, the inverter will convert the battery's
DC power to pure sine wave AC, output from the AC outlet on the rear panel.
Over-voltage protection function: When the battery voltage is higher than the set value, the device
will automatically cut off the inverter output when the front panel LED will flash 3 times per
second and the buzzer alarm will sound. When the voltage drops to the "over-voltage recovery
point", the inverter will start to work again.
Under-voltage protection function: When the battery voltage drops below the set value, the device
will automatically cut off the inverter output when the front LED will flash 1 time per second and
the buzzer alarm will sound. When the voltage raises to the "voltage recovery point", the inverter
will start to work again.
Overload/Short circuit protection: If the load exceeds the rated power or a short circuit occurs, the
front panel LED will blink 2 times per second and the buzzer alarm will sound. When this state
occurs, the unit cannot restore itself. Turn off the power switch, check to see if the short-circuit did
occur and check whether the load is within the allowable range, then turn the power switch back on
to restore inverter output.
Fan, automatic control and thermal protection: If the machine internal temperature reaches the set
point, the unit will automatically start the cooling fan. If the temperature then becomes too high, the
device will automatically cut off the inverter output, the front LED will blink 2 times per second
and the alarm buzzer will sound. This state does not self-recover, so turn off the machine and leave
it off until the temperature of the machine drops down, then turn on the switch, restoring inverter
output.
Reverse battery protection function: The device has complete reverse battery protection, which
means that if the batteries polarities are hooked up incorrectly, the fuse in the unit itself will be
automatically blown to prevent damage to the battery itself and also to your devices. Your devices
and batteries will be safe, but the inverter itself will not be operational.
Protection Functions
Lacking-voltage Alarm: When input DC voltage is at 9.5V ~ 11V, buzzer alarm will sound and the
green LED light will flash slowly. This means that the accumulator will need to be charged.
Low-voltage protection: When input DC voltage is below 9V ~ 10.5V, buzzer alarm will sound and
the green LED light will flash quickly The power inverter with the battery charge will cut off
power automatically, protecting your battery for damage caused by excessive discharge.
Over-voltage protection: When input DC voltage is over 15V, buzzer alarm will sound and the green
LED light will flash quickly. The power inverter with battery charge will cut off power
automatically to protect the inverter.
Anti-polar protection: The fuse will be burned out if the inverter is connected to the wrong
polarities on the battery. In this case, you should turn off the inverter power switch and change the
battery connection cable. The fuse in the inverter will need to be replaced with a fuse of the same
specification.
