Generator Charge Its Battery (How They Work)

Generators are powered by different sources, including gasoline, natural gas, biodiesel, propane, and solar. Solar generators take energy from the sun to create power, which can be used to charge batteries.

Solar power generators are popular because they are environmentally friendly and cost-efficient. 

Here are some of the key points I will cover, plus more you’ll need to know:

  • What is a solar generator? 
  • What are the types of solar generators?

Does a Generator Charge Its Own Battery?

Yes. If the generator comes with a built-in battery, it will charge while the generator is collecting solar energy. Otherwise, you need to connect an external battery. 

A charger is used to connect a battery to the generator. Once connected, an external battery will charge while the generator is collecting solar energy. 

What Is a Solar Generator?

A solar generator uses sunlight as an energy source and stores excess energy in batteries. The batteries provide power to appliances or devices when the sun is not shining.

These generators are used as emergency power sources or to provide power at remote locations that leave buildings without grid access during natural disasters.

Generators come in many varieties, ranging from small portable devices that can be hand-carried to much larger units that require a vehicle to transport. When purchasing a solar generator, it is essential to consider how much power you need.

Solar generators can power appliances that run on 12V DC (Direct Current), like lights, televisions, appliances, and battery chargers.

However, it is crucial to choose a generator that provides the appropriate wattage for the devices you plan to power.

What Batteries Are Used with Solar Generators?

Batteries are either lead-acid, lithium-ion, or saltwater.

  • Lithium-ion batteries are lightweight and operate well in a variety of temperatures. They are expensive, and they last a long time;
  • Saltwater is a new technology that is still being developed. These batteries are expensive but have a long lifespan and can be discharged and recharged many times. These contain a liquid saltwater solution, which is safe and will not start a fire. Unlike the other two types of batteries, these do not contain dangerous materials, so they’re environmentally friendly; and
  • Lead-acid batteries are older technology, are inexpensive, and require more frequent replacement. 

What Is a Charge Controller?

Solar panels harness energy from the sun and convert it into DC power. The power is then sent to the charge controller, which regulates the flow of electricity to the battery.

A charge controller prevents batteries from being overcharged. It works by detecting when the battery has attained its maximum capacity and reducing the voltage to stop charging.

The charge controller stops sending power to a full battery and sends any excess current to the solar panels.

What Is an Inverter?

Energy from the battery must be converted from DC to alternating current (AC).

An inverter is used to convert DC into AC power. The larger the solar generator, the more powerful the inverter needs to be. 

The inverter transfers energy from the battery to whatever device or appliance is required.

What Are Series and Parallel Solar Panel Wiring?

A photovoltaic (PV) module converts electrical current into usable electricity. The PV module comprises many small solar cells that are connected in series or parallel depending on the voltage and current ratings.

Parallel circuits contain multiple paths over which a current can move, increasing amperage but not voltage. If a panel breaks, the circuit will continue to function.

Series circuits contain one path over which a current can move. The voltage of each panel adds together, but amperage remains the same. If one panel goes down in a series, the whole circuit is down.

How Are Solar Generators Used?

Solar generators are used for the following: 

  • Camping
  • RV trips
  • Boat trips
  • Emergency power 
  • Charging portable devices
  • Powering home appliances
  • Powering water pumps
  • A daily source of energy

What Are the Benefits of Using a Solar Generator?

Solar generators are a viable alternative to gas generators, with several distinct advantages: 

  • Solar generators do not produce any emissions and can be environmentally friendly;
  • Solar also has the added benefit of being able to store energy, which can come in handy during power outages or emergencies;
  • Gas generators must be refilled with fuel to continue running. 
  • Solar generators are quiet and create no fumes, making them ideal for indoor use and low noise applications;
  • Solar can be used almost anywhere without disrupting the area; and
  • Solar generators are generally more affordable than gas generators.

What Are the Types of Solar Generators?

Solar generators are either portable or backup.

Portable solar generators are the most common and are ideal for camping, power outages, and charging electronic devices. 

These generators are usually lighter and easier to carry than backup solar generators.

Backup solar generators are designed to provide power during emergencies. They will run for more extended periods.

They are larger and heavier than portable solar generators, but they can provide enough power to keep lights, television, and computers operating.

These units can be installed at home or in vehicles and boats to provide backup power during storms or other emergencies.

Solar generators can also power small businesses or remote locations that are not connected to the electrical grid. They can be used for missions, research expeditions, and other areas where electricity is unavailable.
