Solar panels aren’t the only component that you should be thinking about when you evaluate your solar system equipment. Solar power inverters play an equally important role in a solar system: they convert the electricity your solar panels create into a form that can be used by the appliances, lighting, and other electronics that are in your home. Once you understand how Solar Inverter in Pakistan work, and the different types of inverters available for solar, the Pakistan Solar Traders can help you compare solar quotes with different inverter types.
How Solar Inverter work in a PV System?
When the sun shines on your solar photovoltaic (PV) system, electrons within the solar cells start to move around, which produces direct current (DC) energy. Circuits within the cells collect that energy for you to use in your home.
This is where your solar inverter comes in. Most homes use alternating current (AC) energy, not DC, so the energy produced by your solar panels isn’t useful on its own. When your solar panels collect sunlight and turn it into energy, it gets sent to the inverter, which takes the DC energy and turns it into AC energy. At that point, your solar electricity can power your appliances and electronics or, if you’re producing more electricity than you need, it can feed back into the grid.
Types of Solar Inverters
There are abundant of well-known creators of Solar Inverters all over the world. But there are a few types of solar inverters available in the market which includes the following.
Off Grid Inverters / Hybrid Solar Inverter
Off grid inverters are used in remote systems wherein the solar inverter is fed DC power from a battery panel.This battery panel is charged by solar panels.Several such inverters have integrated with basic battery chargers which can be used to boost the battery from an AC power source.
On grid solar inverter / Grid Tie inverter
An inverter which is associated with the grid can be said to be a grid tie inverter. These inverter feed power in the electricity grid by corresponding phase and frequency. And, the frequency ranges 50Hz in India and 60Hz in North America of the o/p AC power with the effectiveness supplied AC power. These inverters are designed to automatically shut down once sensing a loss of supply from the utility.
Battery backup Inverters
These special types of inverters are particularly designed to draw energy from a battery. The charge of the battery is preserved by using an on-board charger and an additional energy is transferred to the grid. Such inverters have the ability to provide AC power to particular loads during power outages. They also have the anti-islanding function.

Solar Hybrid Inverter
An intelligent hybrid inverter or smart grid inverter is a trending generation of inverter for solar applications using renewable energy for home consumption, especially for solar photovoltaic installations. Some see this as a new technology, however in some parts of the world the application of such products has been around since the 1990s. Electricity from solar panels is generated only during the day, with peak generation around midday. Generation fluctuates and may not be synchronized with a load’s electricity consumption. To overcome this gap between what is produced and what is consumed during the evening, when there is no solar electricity production, it is necessary to store energy for later use and manage energy storage and consumption with an intelligent hybrid (smart grid) inverter. With the development of systems that include renewable energy sources and rising electricity prices, private companies and research laboratories have developed smart inverters for synchronizing energy production and consumption

How Solar Inverter Works And Its Applications
Nowadays, the necessity of the using renewable sources like solar has increased. A solar inverter is a common inverter but uses energy from the sun that is solar energy. This type of inverter aids in changing the DC into AC using solar power. DC is the power which flows in one direction in the circuit and helps in providing current when there is no electricity. Direct current is used for small appliances such as gadgets, iPod, MP3 players, etc. where there is power stored in the battery. In the case of AC (alternative current) is the power that supplies back and forth inside the circuit. Generally, the AC power is used for household appliances.A solar inverter helps many devices that run on DC power to run on AC power so that the operator makes use of the AC power. If you are thinking why to use this inverter as an alternative to the normal electric one, then it is because the solar inverter makes use of the solar energy which is obtainable in ample from the Sun and is clean and also pollution free.
What is a Solar Inverter?
The Solar Inverter is an essential device in any solar power system. Its basic function of the inverter is to change the variable Direct Current output of the solar panels into Alternating Current. The various electrical and electronic components connected in the circuit help in the conversion.
Solar Inverter
The converted Alternating Current power is used for running your appliances like the TV, Refrigerator, Microwave, etc. For some particular applications, we can directly use the Direct Current power from the solar panel such as LED night lights, a cell phone charger. Generally, the power of a home solar power system is used for power AC loads.

The main goal of this project is to design a system which uses solar energy for household loads using an inverter. The hardware requirements mainly include Bridge-MOSFETs drive, Step up Transformer, Voltage regulator, MOSFET driver, PWM inverter IC, Solar Panel, and Battery.
Solar Inverter Block Diagram
Solar energy is changed to electrical energy with the help of photovoltaic cells. This energy is stored in batteries during daytime for the operation purpose whenever needed. The proposed system is designed to utilize solar energy for home loads using an inverter.
A solar inverter converts the DC (Direct Current) output of a PV solar panel into a utility frequency AC (alternating current) that can be fed into a commercial electrical grid (or) used by a local, off-line electrical n/w.
In this proposed system, the solar energy is stored in the battery from PV cells. This energy of the battery is altered to AC supply of 50Hz frequency using PWM inverter IC with MOSFET to the driver MOSFET bridge & step-up the voltage by a transformer, all in off-line n/w only but not grid tie type.
For sample purposes a battery of the SMF kind of and 5 AH (not supplied, it is generally used in small UPS) is necessary to be used as solar cells required would be of very high power type casting very high. Moreover, this project can be added to a charge controller for over voltage, under voltage protection and overload protection.
