How Do Solar Generators Work?

Solar generators work much like batteries—they get charged and then discharged based on the electrical power available to them. Solar panels are the primary source of charge for solar generators. The panels convert sunlight into direct current, which then passes through the charge controller. The controller regulates the voltage in the solar batteries. The energy remains in the battery storage until it is eventually used. When it is time to use the energy, the inverter converts DC into AC so that it can be used by electrical devices. Solar panels are not the only way to charge the generators since most solar generators provide the option to connect to the grid or allow charging via the DC outlet of the car. However, you’ll get the fastest results with the solar panel network.

How Do Gas-Powered Generators Work?

Gas generators are perhaps the most popular choice for backup power supply in residencies. They can easily be installed alongside solar panels. In such a generator, the automatic transfer switch detects a power outage and moves the power source from the grid to the gas generator. Gas generators can run on various types of fuels, such as gasoline, propane, and diesel.

How To Calculate Your Total Solar Energy Needs?

Research has found that an average American home uses about 893 kWh of power a month. By this figure, the daily consumption comes to about 30 kilowatts or 30000 watts daily. Even the biggest residentially available solar generators typically have a capacity of 2000 watts. While this is enough to power small appliances, you cannot run air conditioners or other heavy devices. It is therefore vital to determine your solar energy requirements and the number of solar generators needed. Firstly, you need to identify the devices you will be using the generator for. We've listed the typical power requirements for some commonly used devices. Small to mid-sized RVs: 2000W to 4000W Emergency backup for a large residence: 5000W to 7500W Running multiple household appliances: 8000W to 10000W You might not be able to find anything larger than a 2000W generator. However, if a single solar generator does not fill your purpose, you can add extra batteries to the generator system. Alternatively, you could utilize solar panels for more power.

How Much Solar Generator Power Do You Require?

Since the power from solar generators is calculated in watts, you simply need to determine the total watts you make use of on a monthly basis. Once you’ve calculated this figure, you need to add another 10% or 20% to get a fair estimate of how much power is required. Power consumption of appliances is measured in either amps or watts. Most appliances typically use 120 volts. You need to remember the simple formula—Amps x Volts = Watts. For example, if your total wattage is 5000W, you need a 5200W to 5500W generator system.

How Long Can Solar Generators Keep Running?

Like most generators, a solar power station also springs into action as soon as it detects a power outage. Theoretically, solar generators can probably run infinitely. A solar generator can run as long as it receives power. In case your solar system produces 2000 watts, you can connect it with a powerful generator and have uninterrupted power supply. You can even attach extra batteries to your generator for more solar power. It will enable you to run additional devices. A 2000W solar-powered generator can do the following: Power a 50" television for 50 hours. Charge a laptop for about 40 hours. Support a refrigerator for 30 hours. Charge a smartphone for approximately 300 hours. Run multiple kitchen appliances.
