CHGAOT 4000W High Frequency Inverter Instruction Manual

CHGAOT 4000W High-Frequency Inverter

1. The load (appliances) power aka the output of the inverter shall not be greater than the rated power, which could lead the inverter out of work.
2. Please ensure the input voltage of the inverter of the battery shall comply with the rated voltage, the inverter would be damaged, if the input voltage would be greater than 1.6 times the rated voltage.
3. When connected with an inductive or capacitive load, please reverse the allowance 3-5 times of load power. (aka 4-6 x Appliance power)
4. Red to the positive pole, Black to the negative pole, please connect it properly. Reversely connection would melt the fuse, it could work normally after replacing the fuse and connecting properly.
5. Forbidden to plug the inverter in mains power.

Instructions for use

Please read this manual carefully before using products. Thank you for choosing the vehicle inverter provided by us. We hope our products can bring you the most satisfied service.
Product Description
This high frequency inverter has adapted SPWM technology, and it’s highly efficient and reliable. Product has passed lS09001:2000. However, improper operation or misuse may still cause injury or loss, instruction and information provided in this manual must be followed all the time.

Technical Parameters

Note: Keep the power supply around the ventilation dry, within 1 meters must not have flammable items, strictly prevent the cause of fire.

Protective Functions
Overload protection: when overloading 125%, the inverter will send alarm, and stop working after 20 seconds.

1. Loads are reduced to accepted level, the inverter will resume working.

2. Short circuit protection: inverter is with short circuit protection.

3. Over-temperature protection: when the inside temperature of the inverter reach 80℃, the RED indication light will be on. The inverter will stop working, once the temperature drops to accepted level, the inverter will automatically resume working.

4. Low voltage protection: when the battery voltage is below the setting level, the inverter will send alarm by beeping. When the battery voltage keeps dropping to its shutting level, the inverter will beep, and the RED LED will lit, the inverter will stop working, when the battery voltage is increased to its restart level, inverter will automatically resume working.

5. Over voltage protection: when the input voltage is higher than the setting level, the inverter will stop working, when the input voltage is normal, it will automatically resume working.

6. Reverse connection protection: once there is reverse connection, the inverter fuse will be burnt. ln this case, please switch off the inverter, disconnect the power source, change the fuse.
   REVERSE CONNECT IS STRICTLY PROHIBITED.

7. LCD display: Inverter display as LCD LCD screen, display a variety of states, the following drawings detailed introduction.

installation

1. The function of the inverter is to convert the DC 12v/24v/48v/60v voltage into AC 110v/220V, before connection, please make sure the inverter is switched off.
2. When connecting the inverter to the battery, make sure that the battery voltage is consistent with the inverter reference voltage! ! !
3. Connect the Red cable of the inverter to the Positive pole of the battery, Connect the Black cable of the inverter to the Negative pole of the battery. Do not connect the cable reversely, otherwise, the inverter fuse will be burnt.
4. Turn on the inverter power switch, at which point the green (blue) indicator light is on, indicating that the inverter is working properly.
5. Please connect the loads to the AC output of the inverter, please do not overload. in the case of overloading, the inverter will send an alarm and stop working. To restart the inverter, please first switch off the inverter for 5 seconds, reduce the load, and switch it on again.

Precautions
The inverters are designed, manufactured and tested as per safety standards. However, as an electrical and electric product, it must be installed, operated and maintained strictly according to the related safety instructions as follows:

1. The reverse connection between the inverter and battery is strictly prohibited, it will burn the fuse of the inverter.
2. Please double check if the voltage of the battery matches the inverter input DC voltage, a mismatched connection between the inverter and battery can cause serious damage.
3. Double-check if the connections are correct, and make sure the connections are tight and firm.
4. Do not extend the inverter power cable.
5. When the inverter is not in use, please switch off and disconnect the inverter from the system.
6. Avoid contacting of any foreign objects or fluid. Do not touch the inverter with wet hand. Keep the product away from children. Avoid using it in damp, dusty, high-temperature areas.Do not use this product in1lammable and combustible area.
7. Install the product in a well-ventilated place, avoid using this product on or nearby hot objects such as an electrical heater etc.Do not cover the inverter, avoid direct sun shine, moisture, and water.
8. This inverter can not be parallel-connected.
9. lt’s strictly prohibited to connect this product to the city grid.
10. Do not try to repair the inverter, Once the inverter is opened, warranty is void.

Trouble Shooting

When there is no output, please check the follows:

1. Excessive use of electrical appliances, too heavy load. Solution: Reduce electrical appliances, the use of electrical total power should be less than the inverter-rated power.
2. Overheat protection. WORKAROUND: Reduce load cooling and restart after 15 minutes. (Summer temperature is high or the heat dissipation conditions are poor, should be appropriately reduced the use of the total power of electrical appliances.)
3. It must replace the fuse with the same capacity after fusing
4. Loose connection of the cable: make sure the cable is firmly and tightly connected.
5. Low voltage of battery; please charge the battery.
6. Battery exhausted: Please change the battery, the battery can be exhausted over the years.

Warranty

1. The company provides a free warranty period of one year. Please note that the dealer is in contact with the warranty and repair business.
2. The failure range of this insurance clause does not include damage caused by external factors: incorrect installation, misuse or improper operation, unauthorized private maintenance, damage during transportation, etc.
