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?
Selection of 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. Pure sine wave inverters with conversion efficiency below 80% are not worth buying. Look for inverters with higher efficiency ratings (usually above 85%) to minimize energy loss during the conversion from DC to AC.
- 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.
- Determine Your Power Requirements: Calculate the total power of all devices you plan to power with the inverter. Make sure the inverter is capable of more than this total power.
- Surge Power: Some devices require a higher initial surge of power to start up. Choose an inverter that can handle these surges.
- Continuous Power Rating: This is the maximum power the inverter can handle continuously. Make sure it meets your total power needs.
- Peak Power Rating: This refers to the surge of short-term power the inverter can handle. Check the specs for devices with high startup surges.
- Conversion Efficiency: Look for inverters with higher efficiency ratings (usually above 85%) to minimize energy loss during the conversion from DC to AC.
- Output Waveform Quality: Pure sine wave inverters produce clean power similar to the grid, making them suitable for sensitive electronic devices such as computers and medical equipment.
- Functionality and safety: Look for inverters with overload, short-circuit, over-temperature, and low/high voltage protection.
- Remote control capabilities: Some inverters come with remote controls for easy monitoring and operation.
- Durability and reliability: Choose a reputable brand known for quality and reliability and check the warranty period and availability of customer support.
- Installation and use: Consider inverters that come with clear instructions and necessary accessories for easy installation.
- Portability and size: If you need a mobile solution, make sure the inverter is portable and fits in the intended space.
