1.Short circuit production.9 kinds of protections: 


When the load is short circuit, the inverter will stop working.

2. High temperature production.

When the use environment is stuffy, the heat of the inverter can not be radiated. The temperature is above the rated temperature, the inverter will stop working.

3. High voltage protections.

The battery voltage is above the rated voltage of the inverter, the inverter will stop working.


4. Low voltage protections

The battery voltage falls during the usage. When it is lower than the rated voltage, the inverter will automatically cut the input voltage for the self protection.

5. Surge protection.

It can avoid the DC high voltage surging attack upon the electronic components inside.

6. Overload protection

When the appliances power is higher than the inverters power, the inverter will stop working for self protection.

7. Over current Protection

When the appliances current is  bigger than the inverter current, the protection components on the board will be cut automatically for self protection.

8.Fuse protection.

When the appliances resistance is bigger than inverters, the fuses on the socket will be automatically cut off for self protection.

9. Reverse protection

It can avoid the accidents of burning the inverter if the positive and the negative poles are reverse connected.


The resistive load applications and  the inductive load applications

For resistive load applications:

If you need the inverter to run the resistive load (like laptop, TV, electric cooker, LED light), please choose the inverter with continuous power higher than the appliance\'s rated power.

For example, for the power inverter with continuous power 2500w,it is suggested to run the appliance with rated power less than 2500w. It is best to use 80% of the rated power.

For inductive load applications:

If you need the inverter to run the inductive load (for appliance such as compressor, motor, water pump), please calculate the power of inverter 3 to 7 times higher than the rated power of your appliance.
