A home inverter is a device that converts direct current (DC) electricity stored in a battery to alternating current (AC) electricity, which can power household appliances during a power outage. 

• Modified sine wave inverters: Produce a less pure AC waveform, suitable for most basic appliances but may not work well with sensitive electronics. 
  
   
• Pure sine wave inverters: Generate a clean AC waveform, compatible with all types of appliances, including sensitive electronics. 

Calculate the total wattage of appliances you want to run simultaneously and select an inverter with a slightly higher wattage capacity. 

Most household appliances like lights, fans, TVs, refrigerators, and small kitchen appliances can be operated with a home inverter. 

Battery life depends on the battery capacity, power consumption of appliances, and the inverter's efficiency.
