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.

3Protective Functions

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

1. Loads are reduced to the 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 reaches 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 an alarm by beeping. When the battery voltage keeps dropping to its shutting level, the inverter will beep, and the RED LED will light, the inverter will stop working, when the battery voltage is increased to its restart level, the 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 a reverse connection, the inverter fuse will be burnt. ln this case, please switch off the inverter, disconnect the power source, and 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.
4 Installation
1. The function of 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 battery, Connect the Black cable of the inverter to the Negative pole of 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 firstly switch off the inverter for 5 seconds, reduce the load, and switch it on again.
5) 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:
4

1. 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 mismatch connection between the inverter and battery can cause serious damage. 3. Double check if the connections are correct, 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 it off and disconnect inverter from the system. 6. Avoid contacting of any foreign objects or fluid. Do not touch the inverter with a wet hand. Keep the product away from children. Avoid using it in damp, dusty, high-temperature area. Do not use this product in1lammable and combustible areas. 7. Install the product in a well-ventilated place, avoid using this product on or nearby hot objects such as electrical heaters, etc. Do not cover the inverter, avoid direct sunshine, moisture, and water. 8. This inverter can not be parallel connected. 9. It’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.
6) 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 battery, battery can be exhausted over the years.
7) 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.

Exclusions

The battery is low
The battery voltage is high

Start by making an alarm sound (judge the alarm sound as one, BI-BI-BI… ),
the LED red light flashes, The voltage continues to decrease and
the machine shuts down.
Alarm sound first (judge alarm sound is two, BIBI – BIBI – BIBI…) THE LED
red light flashes, The voltage continues to rise and the
machine shuts down.

The battery is fully charged
The battery is fully charged or replaced in line with the nominal voltage of the inverter

Too much load
The temperature is too high
The output is shorted The battery is turned
back

First issue an alarm sound (judge the alarm sound as a continuous alarm, BIBIBIBIBIBI… ), the LED flashes red
and the machine shuts down.
Alarm sound first (judge alarm sound is three, BIBIBI – BIBIBI – BIBIBI… ), the LED flashes red, the temperature
continues to rise, and the machine shuts down.
Alarm sound without damaging the circuit (judge alarm sound as
continuous alarm, BIBIBIBIBI…)
The built-in fuse is blown and the machine is powered on and unresponsive.

Reduce the load
Subtract the load and wait for the inverter to
cool down
Just disconnect the short circuit
Replace the new fuse
