When it comes to preparing for power outages, there’s no better ally than a solar backup generator. Its ability to harness the unlimited power of the sun makes it a reliable and sustainable solution, providing you peace of mind during unexpected power failures.

Solar generators are typically designed for portable and off-grid use, and their power output is limited compared to traditional backup generators. But they can provide excellent supplementary power when you want to cut back on your grid use and lower your energy bills.

They are also an excellent resource for emergency power once the grid goes down. Plus if it’s portable enough you can pack it up in your trunk or RV and take it with you on your travels, especially if you are going off-grid.

Can Solar Be Used For A Whole House Backup Generator?

To act as a whole house backup generator, a generator must have a large enough capacity to power all essential appliances and systems in a home, such as HVAC, refrigeration, lighting, and communication devices. A typical whole house backup generator has a power output of 20,000 to 30,000 watts, which is much higher than solar generators currently on the market.

But if you make smart choices with your power requirements in an emergency situation, like not running your air con continuously with your solar generator, you can survive, and survive well with your supplementary portable power unit.

See below section about expanding your solar generator with extra batteries and smart generators.

What is a Solar Backup Generator?

A solar backup generator is a state-of-the-art system designed to capture, store, and convert solar energy into electricity. The unit contains a charge controller, batteries, and an inverter, it provides a consistent source of power during grid outages. You also need to accompany it with solar panels. You can buy a complete kit with the panels included, or use your own or existing panels and just buy the generator.

How Does a Solar Backup Generator Work?

Solar panels absorb sunlight, generating a flow of electrons, thereby creating direct current (DC) electricity. The charge controller then manages this DC power, directing it to the batteries for storage. Upon demand, the stored DC power is converted into alternating current (AC) electricity by an inverter suitable for common household appliances.

So basically it sucks up the sun via solar panels and transfers this energy to a battery. You can then plug in all your devices via usb ports, traditional wall plugs and some models can connect to your grid.

Why Choose a Solar Backup Generator?

Environmental Benefits

Solar backup generators are champions of renewable energy. They harness solar power, a clean and limitless resource, eliminating the need for fossil fuels. This translates into fewer carbon emissions, promoting a cleaner and healthier environment.

Cost Efficiency

Though the upfront cost of a solar backup generator might seem significant, the long-term benefits can far outweigh it. The primary operating resource, sunlight, is free, which means you can enjoy virtually zero operating costs. Moreover, with potential government incentives and savings on electricity bills, it’s an economically attractive solution.

Smart Energy Management & Independence

Having a solar backup generator can provide you with a good level of energy autonomy. This technology reduces your reliance on the power grid, allowing you to maintain power during grid failures or shortages. This independence can be incredibly reassuring, particularly during extreme weather conditions or emergencies.

When the power goes out you can keep your necessary cooking, medical and food storage appliances and devices running. Not to forget about having warm water. And having an ample supply of coffee from your machine can get you through many an emergency crisis or power outage!

Choosing the Right Solar Backup Generator

Solar Generator Capacity

When choosing a solar backup generator, the first factor to consider is its capacity. Evaluate your energy needs by identifying the key appliances you would need to power during an outage, and ensure the generator’s capacity aligns with these requirements.

Battery Life

The longevity of the generator’s power supply is determined by its battery life. The longer the battery life, the more resilient you will be during periods of limited sunlight or longer power outages.

Installation and Maintenance

Installation Process

While some homeowners may opt for a DIY approach, professional installation is often recommended to ensure safe and efficient operation. Technicians can provide expert guidance on the best location for solar panels and the necessary wiring configurations.

Regular Maintenance and Safety

Solar backup generators require minimal maintenance, you’ll find primarily maintenance with your kit involves cleaning the solar panels to ensure maximum sunlight absorption. However, routine checks on the overall system, including wiring, connections, and battery health, are also crucial for optimal safety and performance.

The Future of Solar Backup Generators

Solar technology is constantly evolving, making solar backup generators more efficient, affordable, and accessible. As individuals and communities seek to embrace sustainability and energy independence, solar backup generators are poised to play a pivotal role in shaping the future of power generation.

Investing in a solar backup generator is not just a wise decision for reliable power backup; it’s also a commitment to sustainable living and environmental stewardship. While it provides a practical solution for power outages, it also champions cleaner energy and long-term cost savings, making it an excellent choice for homeowners.

Expandable Solar Generators Can Up The Power

One of the drawbacks with using solar is capturing enough power from the sun to power your entire house. Solar generators are limited by battery size and energy storage and they require a lot of solar panels if you want to charge large capacity units. Unless you chain them together. Many solar generators have an expandable ecosystem.

Expandable solar generators provide the flexibility to increase power capacity as per your needs. They come with the option of adding more solar panels or batteries to the existing setup, thereby increasing their power generating and storage capacity.

When your power requirements increase, instead of buying a new, larger generator, you can simply add more solar panels or batteries to your existing system. This is not only cost-effective but also allows for a more customized solar solution tailored to your specific needs.

EcoFlow Delta Pro Expandable Options

The average American house uses 29kWh according to shrinkthatfootprint. So, if you do want total power independence you can run 2 x Ecoflow Delta Pro power stations alongside extra batteries and smart generators to utilize 25kWh of energy. Then you can almost completely opt out of the grid. You also need their smart panel to plug into your home curcuits for this to work.

You won’t have much change out of $10k and it’ll probably cost more if you want the optimum amount of solar panels.

Maybe worth considering if you want to completely escape the grid, over the long term it may be worth it. Even you wanted to use it alongside the grid you may be able to lower your energy costs to between 50-70%.
