Use Required Reading
1. This machine has no reverse connection function, battery positive and negative lines can not be connected back, otherwise it will damage the inverter.
2. There are four 16-square models for the use of two red and two together, two black and in, together. You can not use one alone. Otherwise the current is not enough to carry the high power.
3. When the INVERTER is not in use, please turn off the inverter switch, so as not to affect the life of the internal components, loss of battery power.
4. 12V high voltage protection voltage is 15V, 24V high voltage protection voltage is 29V, 48V high voltage protection voltage is 57V. Do not exceed the voltage, or the inverter will be high-voltage protection, do not work.
5. If you want to extend the lead between the battery inverter to be thickened.
6. Battery is how many volts must use how many volts inverter.
7. The larger the battery number, the greater the power used. The power of the battery is small.
8. Smart Fan has 2 boot modes
1) The inslde temperature reaches 45 intelligent fan starts.
2) If high power is used, the intelligent fan turns straight and the low power does not turn.

Matters needing attention
1. The installation and commissioning of the equipment shall be carried out by professional electrical maintenance personnel familiar with the struct-ure and operation hazards of the device.
2. Failure to comply with this precaution may cause physical injury.
3. Do not connect this equipment to the civil power distribution box, such as home lines.
4. The inverter should be away from water, avoid water droplets on the mac-hine or gradually above, do not use wet hand plug or unplug.
5. If the inverter is in a cool environment, the appropriate temperature should be -20degrees Celsius ~ 50 degrees Celsius, avoiding direct sunlight and hot air vents.
6. Inverters should be kept away from flammable substances, or where flam-mable gases are accumulated.
7. After long-term use, the inverter will heat, so avoid close to the heat-sensitive substances.
8. Ensure smooth ventilation and good heat dissipation.
9. High pressure danger, please do not open this machine.
10. Use the right type of wire to avoid fuse because of excessive inverter current.
11. Make sure the inverter connects the correct battery, otherwise it will fuse the fuse of the inverter. Turn off the switch when the machine is not in use.
12. Please turn off the switch and clean with a dry cloth before cleaning.Do not use wet cloth or cleaning agent.

Product Characteristics
The inverter adopts the SPWM technology of MCU micro-processing control, pure sine wave output and pure waveform. The unique dyna -mic current loop control technology ensures the reliable operation of the inverter. Strong load adaptability, including inductive load, capacitive load, resistive load, mixed load. Strong overload and impact resistance. With input overvoltage, undervoltage, overload, overheating, output short circuit and other perfect protection functions. Sinusoidal inverter adopts LCD liquid crystal display mode, the state is clear at a glance. Stable performance, safe and reliable, long service life.

FAQs and Solutions
1. Outside interference: The inverter may be disturbed by some strong electromagnetic waves in use, such as nearby motors, power converters, strong magnetic fields, etc.
2. The inverter has no reaction:
1) The battery and inverter are not connected and reconnected.
2) The pole of the battery is reversed and the fuse is fused. Replace fuse.
3. Low output voltage
1) Overload, load current exceeds nominal current, turn off partial load and restart.
2) The input voltage is too low. Ensure that the input voltage is within the nominal voltage range.
4. Low Voltage Alarm
1) The battery is dead and needs to be charged.
2) Battery voltage is too low or poor contact, recharge, check battery terminals or clean terminals with dry cloth.
5. Inverter without output
1) Battery voltage is too low, recharge or replace battery.
2) The load current is too high, turn off part of the load and restart the inverter.
3) Inverter overtemperature protection. Let the inverter cool down for a while and put it in a ventilated place.
4) The inverter failed to start and restarted.
5) Terminal connection, fuse, replace fuse.
6. The inverter does not work: Check the power switch, fuse and battery connection or smoke.
