Product Description

JN-H series Pure Sine Wave Inverter User Manual

Firstly, thank you very much to purchasing our product JN-H pure sine wave inverter. For your better use and understanding of our products .Please read this user manual clearly before installing and using the equipment, and keep it properly. You need following this manual when install and debug the inverter. It may damage the inverter and other electrical equipments or your body if misused or incorrect connection inverter.
Warnings
1. Electric shock should be avoided and also keep it away from children!
This inverter output is standard pure sine wave AC power, and the AC output socket has high voltage alternating current ,like the same general household  AC outlet ,there is potential danger .Stay away and don't touch it because it may cause serious consequences or death. Please keep away from the children and intellectual disabilities, or it may cause dangerous.
2. Do not close to flammable explosive materials.
Do not use this inverter where there's flammable and explosive gas. Such as, gasoline ship hull or propane tanks, etc.
3. High voltage risk. do not disassemble and touch freely.
Unauthorized disassembly or modification of this inverter may result in serious accidents. High voltage inside the inverter to prevent electric shock.
4. Do not connect the wire whatever you want.
This series of inverter is used for off -grid solar system. Both of the CND line of inverter and electronic equipments should be connected to the ground. AC output zero line shouldn't be regarded as GND wire. It's not be allowed to connect ac inverter to electricity grid.  (eg: family 220V AC line). Otherwise, inverter maybe damaged even though power switch of inverter closed, moreover, fire may be happen.

II. Usage
The installation should be operated by a person with enough electrical theory knowledge or somebody who acquire practical experience.
1. Connection Steps:
(1)Check if all the components are all included.(such as, accessory bags and operation instruction. At the same time inspect whether battery(power) voltage is accordance with the inverter rated input voltage. The input battery (power supply) must be able to provide enough current. Details calculate is that the output power /input voltage/0.85=output current.
For example: load of 1000w, the output voltage is 12v, so the input current =1000/12/0.85=98 (Ampere).
Appropriate connection wires should be chosen according to the current rule that within 1 meter 8A/mm. 12mm connect wires should be regarded as the 1000w inverter with input voltage 12v. and so on.
2) The GND wire of inverter should be connected to ground firstly before using. Do not regarded zero wire as the ground connect line.
3) Close the power of inverter, ie, press down the button "OFF" .
4) Confirm the positive and negative polarity of battery, high voltage is the positive and low one is negative.
5) Pull out the inverter input terminal, red means positive polarity (+) and black refers to negative polarity (-).
6) Choosing the suitable black area line according to the first step and then connect to black wire of inverter input terminal and pull tight at last.
7)Choosing the suitable red area line according to the first step and then connect to red wire of inverter input terminal and pull tight at last.
8) Connect the black wire on the other side of the battery negative pole and ensure connection is firm.
9) Connect the red wire on the other side of the battery positive pole and make sure connection is firm.
10) Check and confirm all the connection is correct and then the turn on the inverter power, just press the button "ON" is ok.
11) Inverter will get stable alternate current within 5 seconds after the inverter's normal working indicator light green light turn on.
12) Connect the power equipment not exceeding the nominal rated power of the inverter to the AC-OUT socket at the output of the inverter.
13) Press the button "ON" and then the power switch of load will be opened.

IV.Notice

1. The inverter only can be connected the load with the power which less than rated power.

Notice: Two or three times power of inverter should be chosen for some electronic equipment with high start current. LIke: Refrigerators, freezers, color TV, water pump, motor, air conditioning, air compressor, computer and similar appliances are included.
(2) Battery voltage must match with the input voltage of inverter, otherwise, it will damage the inverter with high voltage.
(3) Prohibited reverse battery although anti-reverse protection, to avoid damage to equipment! 
(4) Minimize input wire length, as the larger of inverter input current, to reduce the loss.
(5)If the inverter turn on and the output power is too large, lead to generate output protection, it should be shut down, reduce the load, after 10-15 seconds turn on again, if the frequent overload boot will likely make the inverter permanently damaged
(6) It is forbidden to connect inverter with electricity grid, otherwise, inverter may be damaged permanently.
(7)Do not using your wet hand touch the inverter and operate it in moist environment .It should be used in the cool and ventilated environment.

Notice: Do not block the air outlet and inlet of inverter cooling fans, keep it in a good ventilation environment.

(8) Inverter should be closed if it's not in working status. Disconnect the inverter and battery if long time using or go outside for long time.
(9) Output voltage and frequency of inverter should be match with the electric equipment .Or, it will damage the electric equipment.
(10) If used in the place where elevation above 1000 meters, increase 1000 meters above sea level per time, the output power should be decrease 5%..

V. Common troubleshooting (just for your reference)
1. The indicator light is off and not in working status after inverter started.

1. Check if the connection is bad, or reconnection it.
2. Check whether wire between battery and inverter is reverse or not, if yes, please reconnection and change a new and

same specification fuse for inverter.
2. Warning indicator light turns red and no output from inverter after it started.

1. Please check if voltage specification for battery is matched with inverter rated input voltage, if not, please kindly change it with a right one.
2. Check whether battery with enough power or not, otherwise, please change a new one.
3. Check if the temperature too high, ie, more than 70 Celsius degree, or, please cool down the inverter and then put it in a ventilate place. Restart it after inverter come to a normal temperature.
4. Check if the load power exceed inverter rated power, if yes, please decrease load power or change a higher power inverter and then restart it.
5. Check and make sure output and load terminal aren't short circuit and then restart it.
6. Please restart it 10 seconds later after power on if starting inverter failed first time.

VI. Cleanliness & Maintenance

1. Wipe off the dust on the surface of inverter cabinet gently with a dry towel
2. Please dip appropriate cleaner to wipe if too much dust or oil
3. Cleaning outlet and inlet of fan with brush regularly
