How Does A Solar Generator Work

How does a solar generator work? We often see some black glasses arranged in rectangular and placed on buildings or houses’ rooftops. These are known as solar panels that make the solar generator work. Solar generators create sustainable, reliable, and independent energy. This system runs your places 24 hours a day and seven days a week without gas and oil.

How does a solar generator work?

In this article, I have explained how a solar generator work in detail. Although it may sound technical, do not worry it is not that complex. But has a little bit of theory that you have to know about your solar generator.

A solar generator uses solar panels to capture the sun’s energy and then convert it to electricity. These panels capture the sunlight power and then convert it into direct electricity or current. This direct current then travels to the solar battery inside the generator through a charge controller, which is used to regulate voltage and the amperage. Then an inverter converts the stored direct current into the battery in AC. AC is the energy source that most appliances need. Some appliances also have a DC port.

What is a solar generator?

A solar generator is a portable power bank that stores solar-powered electricity and then provides you on demand. It is completely different from other regular power generators. It has batteries that store energy in itself and use it for later. A solar generator consists of four components that serve as a backup electricity source for electric appliances.

Working of solar generator:

Here I explain how does your solar powered generators work in a step-by-step approach.

  1. Once your solar energy panels starts producing energy it goes to your charge controller.
  2. Electricity travels through the wire and it’ll go to your charge controller.
  3. Then this energy goes to the BMS (battery management system). The BMS sense the voltage that’s inside your battery pack.
  4. Once it reaches full capacity on charge, your BMS will send the signal to your charge controller to stop sending more electricity to your battery for charge.
  5. Once your battery is charged, the charge controller will get disconnect from the solar panel. You’ll be in a full state of charge for your battery.

Pro Tip: If you take care of the battery, it’ll ultimately take care of you and will last longer.

Components of solar generator:

A solar generator is different from a regular generator because it involves equipment like solar panels, a charge controller, a battery, and an inverter.

Lets break these parts in alliance with their functionality.

1. The solar panels:

Solar panels are placed where sunlight can reach them easily often on the rooftop or outside open area of the house and uses solar panel connectors to connect with a generator inside the house. When the sunlight hit the solar panel, the solar panel will automatically generate electricity.

2. The charge controller:

The purpose of the charge controller is what the name says, it controls the charge from the solar panel to the battery pack. This component is used to regulate the voltage and the amperage. Also responsible for preventing overcharging of the battery. The charge controller blocks the current from going back to the panel. The charge controller also drains out the unnecessary battery.

3. The Battery management system(BMS):

This Battery system is located inside the solar generator and is used to store solar energy. More often, lithium-ion batteries are used because they are durable. These Batteries are easily maintained and have a long lifetime.

4. The Inverter:

The solar generator inverter’s main function is to convert direct current in AC. As most appliances are functional on AC instead of DC. So, it is essential to invert the from DC to AC.

5. The ports and the outlets:

The solar generator has several ports to plug in the devices. These include the Ac outlet, USB A and C ports, and the carports.

Categories of solar generator:

There are two main types of a solar generators are here:

1.    Solar backup generators:

Solar backup generators are used to provide emergency backup in power outages. These use many batteries to increase energy storage and have a high capacity. Mostly used for home appliances and work as an efficient generator.

2.    Portable solar power generator:

This kind of generator is used to back up small areas and has low capacity. Portable solar generators are lightweight and can be easily move from one place to another.

Benefits of solar generator:

Solar generators provide a green solution that can be more effective than gas generators. Also having backup power for your home appliances and personal devices is essential as more and more people rely on these technologies to survive to thrive and connect with others. Solar generators are not only used to power home appliances like fans, small to medium size air conditioners, and refrigerators but are also useful for providing reliable backup power for critical medical devices such as CPAP machines and other at-home health monitors.

The solar generator is used for recreational activities such as fishing, camping, or RV trips when it comes to these activities investing in a portable solar system is the way to go.

Advantages and disadvantages of solar generators:


  • Have Unlimited stock of energy
  • Are lightweight and easily moveable
  • Are environment-friendly
  • Best source for backup power
  • Need low maintenance
  • Have no noise


  • Expensive
  • Have limited power supply

Why not gas generator:

If you go to an average home after a typhoon season when the powers are down every three days on average they spend 5 dollars on gas. Every seven-week, they have to do maintenance which means they are going to change the oil. You also have to change the spark plugs, drain the gas tank, and replace it again. Therefore, lots of maintenance goes into it and you have to spend a lot of money on it.


How much time does your solar generator need to charge?

Your solar generator gets charged in around 48 hours according to its capacity. However, this time depends on its size and its energy resources.

Can you plug in your solar generator all day?

Yes, you can plug in your solar generator all day. It will not damage your solar generator.

How noisy your solar generators are?

No, solar generators are not noisy. Because it does not contain any moving components and this helps to perform tasks in silent mode.

Can your solar generator also work after sunset?

Yes, your solar generator can work all day even after sunset. Solar generators work all day and store electricity with solar panels. You can use this electricity at night with a battery of solar generator.


The solar generator can provide energy consistently over a long period without requiring anything other than the sun. Whether you are in search of a practical off-grid living alternative or want a standby power supply in case of a power outage.

In this article, I briefly describe how a solar generator work. The solar generator has some important components that convert sunlight to direct current and these components are; a charge controller, battery management system, inverter, solar panels, and ports or outlets. For more detail, read the above article in detail. After reading this article, hopefully you have get a clear about the working of solar generators.
