Protects against overloads and short circuits. The capacity of the inverter here means that maximum power limits the demand to which it can operate and provide electricity. Ideally, inverters between 756 and 1000 W are best suited for homes. There are also several other types of capacity-based inverters.
First of all, what load do you intend to feed? Let's say 1 TV (125 W), 8 light bulbs (6 W each), 2 fans (65 W each), 1 decoder (25 W) and 1 laptop (85 W). The total power required will be calculated as “%3D of device power x quantity”. Therefore, you'll need a total power of (125 × +) (6 × bulbs + (+) 65 × fans + (25 × decoder + (85 ×%) 3D of 410 W. This number will be the smallest inverter that can meet your needs, so it's a good idea to add 10 to 20 percent in addition and then buy an inverter of that size or more.
When the inverter uses appliances with high continuous charging capacities for long periods of time, it is not recommended to power the inverter with the same battery that was used to power your car or truck. Since most inverters indicate the surge power they are capable of, you should ensure that the inverter has a rated surge power greater than the total power of the devices and appliances you want to power it. In general, an inverter with a capacity of at least 2000 to 3000 watts should be used to power a house, although larger inverters will be needed for homes with a higher demand for electricity. In addition, an inverter that is too large will not be as efficient as an inverter of the right size.
You may find it practical to purchase a small pure sine wave inverter for any special needs you may have, and also a larger modified sine wave inverter for the rest of your applications.
