An inverter is generally a device for converting DC voltage to AC. The inverter receives DC power from sources such as batteries, solar panels, or fuel cells and converts it to AC power.
The output power can be converted to any voltage required.Inverters are divided into two main types in terms of phase: single-phase and three-phase. Also in terms of output waveform are divided into the following four types:
1. Square waveform output
2. Modified sinusoidal output (normal)
3. Modified sinusoidal output (stepped)
4Pure sine output
The recommended inverter for solar systems is a pure sinusoidal inverter, but the use of quasi-sinusoidal inverters is not a problem for the system if the sole purpose is to provide lighting or power to the CCTV camera.
Other categories of solar inverters are grid-connected and grid-independent.
Grid-connected inverters power AC-powered equipment by converting DC to AC voltage. The most famous brands of inverters connected to the network are SMA, Growatt and Steca. Cotek, Minwell Meanwell, EPEVER and SMA are also among the most well-known models in the field of grid-independent inverters.
