How to Buy a Home Solar Generator: A Simple Guide for First-Time Buyers

Homeowners are not as interested in solar generators as they used to be. But, they come with many benefits and can lead to substantial cost savings on your energy bills over time. These days, most people purchase their home solar generators instead of renting them from the power company.

If you’re considering buying a home solar generator, here is everything you need to know about buying a home solar generator and whether it makes sense for you. If you have ever rented a home in an apartment complex, there’s probably a home solar generator somewhere on your property.

These units provide power throughout the entire property and reduce the load on local power grids by reducing demand during peak hours. That way, everyone has access to affordable energy whenever they need it most.

What Is a Solar Generator?

Solar generators work with solar panels to provide constant emergency backup electricity to your home. It is beneficial if your electricity goes out. Still, you may also use it for off-the-grid living and camping. Generators are available in different options that include styles, sizes, utilization, and brands. 

You can purchase a ready-made solar generator or build your own. It all depends on your needs and what you have access to. But the important thing to consider is the customer support of the company, which will be helpful in the near future if you have problems with your unit.

The most common type of solar generator uses an array of solar panels to generate electricity and store it in a battery. During the day, when there is sunlight, the solar panels produce electricity. This electricity is then stored in a battery to be used at night when there isn’t any sunlight.

These generators work well for providing backup power in case of an emergency, as well as for off-the-grid living. You may also consider choosing a light weight unit to easily move it. 

An electrical outage can be quickly remedied by installing one of these kits, which includes a backup generator, solar panels, and a transfer switch. You’ll also be able to connect your solar generator system to all of the necessary wires and electrical components as smoothly as possible. 

How Does a Solar Generator Work?

A solar generator produces DC electricity from sunlight using a solar panel. The charge controller regulates the flow of electricity from the panel to the battery. An inverter converts the AC electricity generated by the inverter into accessible DC electricity.

You can use this power to charge phones, run appliances, like the fridge, or power lights. The size of your solar panel determines the amount of power generated. To get the most out of your solar panel, it is essential to position it correctly.

You’ll receive the most power in the summer when the sun is the strongest. The tilt of the solar panel also matters a great deal. Most panels should be angled between 35 and 45 degrees from horizontal to receive the most sun.

You’ll also want to ensure that your panel is clean, as dirt and debris can significantly reduce its efficiency.

Powered Backup Generators

Consider a powered backup generator if you’re looking for a reliable backup power solution. These generators are designed to provide backup power during power outages and can be used to power essential appliances and electronics.

Powered backup generators are available in various sizes and configurations to choose the suitable model for your needs. When shopping for a backup generator, consider the following factors:

Installing a Solar Kit as a Whole House Backup Generator

Despite being relatively new, solar generators are now offered in all-in-one packages. Solar generator systems have been around for decades, but the recent release has spurred production and marketing.

DIYers or anyone interested in taking on a home improvement project may install solar kits as a backup system for their whole household. The only difference is that each component of the solar generator is acquired and installed separately, which can save space and costs.

We will discuss the key components of a solar kit for whole-house generation in this article and the important factors to consider when buying and installing them.

Solar Panels

You want a high-quality solar panel installation to build a home that generates all of its electricity. Your house will only be able to run its electrical equipment as long as there’s electricity in the battery if you don’t plug your power station into a renewable energy source.

You may determine how many solar panels you require to operate your generator optimally with a solar generator. Solar generators are usually rated with a maximum solar input wattage to safeguard electricity production. 

ecoflow generator

Solar generators of medium size can charge approximately 100 to 500 watts of solar energy, while the Titan can accept up to 1,000 watts. When purchasing a standalone solar kit, you should consider your electrical load, spatial limitations, panel efficiency, and warranty periods.

You should also consider your anticipated electrical load when determining the size of your solar array.

Solar Batteries

The most significant part of an off-grid generator is the solar battery, which is the lifeblood of your home’s backup system. To prepare well for a crisis, the general rule of thumb is to have as much energy as possible. When selecting an off-grid backup system, you must consider the voltage.

While a 24V system charges all parts at the same rate, a 12V solar panel array charges 12V batteries. 

When purchasing a solar battery, you must know the voltage, chemistry, and storage capacity in addition to voltage and chemistry. You should buy one or more batteries capable of storing your approximate electrical demand while temporarily independent of the grid.

Charge Controllers

The two charge controllers in the Titan generator allow it to receive such a large amount of solar electricity.

Most solar generators and small stand-alone systems have only one charge controller, so two charge controllers may be required between the panels and the battery bank in a full-home off-grid solar storage system.

MPPT vs. PWM Solar Charge Controllers

There are two primary types of charge controllers: MPPT and PWM. Although MPPT controllers are more sophisticated, a PWM controller may be sufficient to maintain a battery bank for occasional use.

Choosing What’s the Right Solar Generator for You

There are a few things to consider when choosing a solar generator. 

  • The first is what you will be using it for. If you need it for emergency power, you will want a generator that can provide enough power for your needs. 
  • The second is how often you will be using it. A smaller generator may be all you need if you only need it occasionally. 
  • The third is how easy it is to use. 

Some generators are very easy to use, while others require more knowledge.


For many people, buying a solar generator sounds like an impossible task. The truth is that a solar generator is not nearly as expensive as you may have heard in many articles or reviews and has numerous benefits.

For example, buying a solar generator can help you save money on your monthly utility bills and reduce your carbon footprint at the same time. These generators are powered by the sun and don’t use any fuel, so they can run nonstop, even in cloudy weather conditions.

Before you buy your first home solar generator, you should know the advantages and disadvantages of this kind of technology and how to buy one.


Which is better, a whole house generator or solar?

There are pros and cons to both whole house generators and solar panels. Solar panels are more environmentally friendly but require a sunny area and can be more expensive to install. Whole house generators can be used anywhere and are less costly to install, but they use more fuel and are louder.

What size generator do I need to live off-grid?

Inverters should be around twice the size of their continuous output to power them correctly. For instance, you should connect a 4,000-watt inverter to an 8,000-watt generator. A minimum generator size of 8kW would be sufficient to power the loads and recharge the battery bank.

How many hours will a solar generator last?

A solar generator with a lithium battery is an excellent investment for anyone who wants to be prepared for a power outage. The watt-hours delivered by lithium batteries typically last 2 to 3 years, regardless of how often they are used.

A battery backup is a good investment. However, lead-acid batteries have shorter life cycles. You can also use battery storage to save money on solar incentives and offset peak demand rates.
