A solar inverter or PV inverter is a type of electrical converter, which converts the variable Direct Current (DC) output of a photovoltaic (PV) solar panel into a utility frequency Alternating Current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

Types of Solar Inverters
Solar inverters may be classified into two broad types:
⦁ Stand-Alone (Off-Grid) Inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays.

⦁ Grid-Tied (On-Grid) Inverters, which match phase with a utility-supplied sine wave. The key role of the grid-interactive or synchronous inverters or simply the grid-tie inverter (GTI) is to synchronize the phase, voltage, and frequency of the power line with that of the grid. Solar grid-tie inverters are designed to quickly disconnect from the grid if the utility grid goes down.

⦁ Hybrid Inverter – 2020 Beginning Year in India.

A hybrid inverter is the combination of an on-grid and off-grid solar inverter. This inverter can control the solar panel arrays for storing batteries and power grids, simultaneously. These are more versatile but more expensive than on-grid and off-grid inverters. It can easily work without a grid, store electricity to batteries as well as export the excess electricity to the grid.

Benefits of Hybrid Solar Inverter

It works On-Grid as well as Off-Grid Inverter. It is a stand-alone system and can work without a grid. It can store electricity and provides power backup. You can also export excess electricity to the grid.

Features of Hybrid Solar Inverter
#1. More Efficient - If there is a power cut or the grid becomes unstable the hybrid solar inverter automatically switches over to battery supply and continues to operate independently from the electricity grid.#2. Portable – Due to its lightweight, a hybrid solar inverter can be easily moved from one place to another.
#3. Long Life – A hybrid solar inverter comes with a lifespan of 5 years.
#4. Compact Size – A hybrid solar inverter is available in a variety of sizes and is usually about the size of a medium fridge. 
#5. Service Free Product – A hybrid solar inverter is an IoT based product and hence requires zero to very less servicing and maintenance.
#6. Display Features - These units come with a display unit/ touch screen that displays voltages, temperatures, outputs, etc.
