300w Off-Grid Inverter Application :
- User Manual of Power Inverter(small)
- Thank you for purchasing Mein inverter ! No matter connector to
Autos cig lighter socket or other 12v or 24v batteries ,
- can it supply sound AC power for household appliances, official
equipments and other electrical devices,such as ,TV sets,
- Electric fan,Refrigerator,lighting lamps,DVD,Amplifier, Audio,Video
cam,electrical tools,fax simile,Photocopy
- machine ,laptop. It is a necessity at field operation,driving
travelling,mobile office and power-off emergency,which become
- the best solution to the urgent demand of power supply on the
occasions of driving and power shortage .Please read the
300W Off-Grid Inverter guide book carefully before use.
A, Product Characteristics:
Adopted with advanced PWM chip technology,it is turned to be
small,light,quiet and of high conversion efficiency,It has
multi circuits protection,securely protecting your appliances and
car circuit. Its output port is conformed to all countries’s
standards. And ,we add 5v USB output charge socket on 60W~400W
inverters, can charge appliances with USB port,
such as MP3, digital camera,and mobile phone.
B, Operation environments:
1: Dry, Do not expose to water or spray.
2: Cool, Operate only in ambient temperatures between 0C and 45C.
3: Ventilated, Allow at least 5cm around the inverter are clean and
1: The input voltage of the inverter is in conformity with the
battery specified voltage.
2: The voltage of the appliance corresponnds with the inverter
specified output voltage.
3: Distinguish the polarities of the cigarette power cord or the
The red one is “+”,the black one is “-”,otherwise may damage the
4: The bigger the power of the appliance is ,the faster the
depletion of the battery’s power
will be and the bigger the capacity of the battery should be .
5: The AC output socket of the inverter can only supply
the domain electrical network from the power plant is not allowed.
D, Operation ways:
1: Assure the power of the appliances is under the the rated output
2: Put the switch on the “OFF/ON”Positon, insert the appliance’s
plug into the socket of the inverter, plug of the cigarette light
into the car’s cigarette light socket.Assure them connect
correctly.(Caution:The car’s cigarette light port only apply power
under 200W;when excess of it, please use the crocodile clip
cords,connect the sun terminal of the cord to the posts of the
inverter.The red connect to the “red”,the black to the
“black”;connect the other end of the cord with the crocodile clip
the posts of the battery, red to the “+”,black to the “-”.)
3: Put the switch on the position of “ON”,the green light is on,the
inverter begins to work.
4: When the green light AC/OUT is flashing and the alarm beeps with
inverterval,it means the inverter is under the protection
situation.Please turn off the switch,check if it is overload or
short circuit, check if the unput voltage of the battery is
abnormal,restart an use it after the problem is solved.
5, Instruction for charge:
1: When the power is depleted,charge the battery as soon as
possible,insert the plug of the power cord into the AC110~240
socket ,the other end into the inverter’s AC input port,charge it
about 5-15 hours(According to the battery’s capacity,the
bigger the capacity is ,the longer the charge time is ,the charge
is in stable mode with fixed voltage and current,when the
battery is full,protection effects automatically.).till the CH/Fu
lights off, which means the battery is full.Only inverters with
revert-charge function can charge the battery,the models
are:CH-500W GH-800W CH-1000W CH-1500W CH2000W
2: During charging,the cooling fan speed will change with the
ambient temperature(the higher the temperature is ,the faster the
speed is ,on the contrary,the lower the temperature is,the slovwer
the speed is ,eventually stop running.)
E, Failure and troubleshooting :
1)Inverters don’t work
A. Check if the plugs are connected properly,tighted or not.
B. Check if the switch is on.
C. Check if the cigarette lighter socket output voltage(If has
cords,check the polarities are right,
red to “+”,black to “-”,check if the battery is depleted.
2). Inverter output power is too low.to run a bigger electrical
A. The capacity of the battery is too small(change the battery or
shut off sone electrical devices.
B. The voltage of the battery is too low(charge or change it).
C. If the inverter can work normally at other cars,you need to
thicken the cord of the car cigarette lighter socket at a
professional Auto shop.(Do not excess of 200W while using cigarette
D.If connected to battery,(thicken the cord,or shorten it).
3)The inverter doesn’t work,Green light AC flashes, and the alarm
beeps from time to time.
A.The power of appliance is excess of the rated power,result in
protection,just reduce the power of the appliance.
4).Inverter beeps from time to time.
A.The voltage of the battery is too low(charge or change it).
B.Reduce the power of the appliance.
5)The temperature of the inverter is too high, it is normal when
under 65C(It has overheat protection).
