A pure sine wave inverter can convert direct current to alternating current. Unlike square wave inverters and modified sine wave inverters, pure sine wave inverters produce waveforms similar to those we get from commercial grid systems and can drive a variety of electronic devices including inductive loads. So, how to choose a pure sine wave inverter?
- The output power
The output power of the pure sine wave inverter should be greater than the sum of the power ratings of the appliances you need to run at the same time. Therefore, first determine the power requirements of your appliance. After determining the power requirement, give the inverter a certain expansion value. Our recommended scaling value is around 1.2 times the power requirement. - Battery voltage
In addition to the total output power, the battery voltage also needs to be considered. If the battery voltage is 24 volts, you should choose a 24 volt pure sine inverter. - Conversion efficiency
Pure sine inverters come in many forms, with different capacities and different efficiencies. The efficiency of the inverter is a key factor that you should pay close attention to. Conversion from DC to AC usually generates heat and causes losses. Therefore, before purchasing a pure sine wave inverter, be sure to read the instructions carefully. Inverters with conversion efficiency below 80% are not worth buying. - Run time
Run time refers to the time the inverter can run. This largely depends on the capacity of the battery (measured in Ah) and the total power to run the device. Make sure the battery has enough power to run the inverter with the required electrical equipment.
