A solar inverter, or converter or PV inverter, 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. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
Solar inverters use maximum power point tracking (MPPT) to get the maximum possible power from the PV array. Solar cells have a complex relationship between solar irradiation, temperature and total resistance that produces a non-linear output efficiency known as the I-V curve. It is the purpose of the MPPT system to sample the output of the cells and determine a resistance (load) to obtain maximum power for any given environmental conditions. The fill factor, more commonly known by its abbreviation FF, is a parameter which, in conjunction with the open circuit voltage (Voc) and short circuit current (Isc) of the panel, determines the maximum power from a solar cell. Fill factor is defined as the ratio of the maximum power from the solar cell to the product of Voc and Isc.
After knowing in detail what is a solar inverter and how it is a suitable making appliance work at residential & industrial levels we must discuss about the several advantages of the solar inverter.
Solar energy has constantly helped in decreasing the greenhouse effect and global warming.
By using of solar based devices will help in saving money and also energy. Because many people have started using these devices.
A solar inverter helps in changing the DC into batteries or AC. This supports people who use a partial amount of electricity.
The synchronous solar inverter that helps small homeowners and also power companies as they are huge in size.
The multifunction solar inverter is the finest among all and works powerfully. It converts the DC to AC very carefully which is suitable for commercial establishments.
This inverter is cost effective, i.e. low cost than generators.
Apart from these there are additional devices too, that make use of solar energy such as, solar heater, cooker.
Mobile charger with fan optional
Temperature compensation for better battery charging for various climate and terrain
Battery reverses polarity protection with fuse
3/4 LED indication systems for system and battery status
Efficient Over charge and deep discharge protection
