There’s a growing shift toward sustainable home backup power, and solar has emerged as an excellent alternative that doesn’t emit fumes, run on fuel, or require maintenance.
EcoFlow’s range of solar generators eliminates ongoing fuel costs and storage concerns. If you have room for a battery, a few solar panels, and enough sunlight in your area, you can swap your gas generator for a solar generator and get eco-friendly and consistent backup energy.
Compare Solar Generators to Gas Generators
When the electricity goes out, solar generators are a cleaner, quieter, and more convenient solution than traditional gas generators.
Solar Generators
Solar generators can be used indoors or as a complete home solar system. They don’t require fuel, require minimal maintenance, produce zero emissions, operate silently, and can charge during outages using solar panels.
Pros
No toxic fumes, no risk of carbon monoxide poisoning
Can safely use indoors
Run silently
Sustainable alternative that reduces your carbon footprint
Minimal maintenance
No fuel storage required
Can recharge using solar power
Cons
Higher upfront cost
Weather-dependent charging
Limited power output compared to large gas generators
Gas Generators
While gas generators have a high output, a low initial cost, and can work in any weather, they’re also noisy, produce toxic fumes, must be used outdoors, and require ongoing fuel costs and regular maintenance.
Pros
High output
Lower upfront cost
Weather independent
Cons
Noisy
Produce toxic carbon monoxide emissions
Must be used outdoors in a well-ventilated area
Require fuel storage for continuous operation
Ongoing fuel costs
Require regular maintenance
Cut Grid Ties: Solar Power for Home Backup
Solar generators empower you to cut your ties with the grid completely. If you want to connect the generator to your home for automatic electricity access, just look for a solar generator that slightly exceeds your home’s energy requirements. The EcoFlow DELTA 3 Plus Solar Generator (PV220W) is a good entry-level home backup choice.
Your system will capture sunlight during daylight hours and convert it into usable energy stored in the battery element. With consistent sunlight, you can power your home long-term beyond emergency backup during outages.

Choose the Right Solar Generator: Lifestyle, Power, and Space
Choosing the right solar generator requires considering your lifestyle, energy requirements, and the available space in your home.
Lifestyle
How often does your area experience power outages? If it’s frequent, you’ll likely need a solution for essential devices, not just convenience.
You should also consider the number of people living in your home and your consumption patterns. Are you using a lot of electricity at times with little sunlight? That could prove challenging unless your generator can capture enough energy when the sun is at its peak.
Power Requirements
This is arguably the most critical part of choosing a generator. A generator with an output that is too low won’t run all the appliances you need, and a generator with an output that is too high will incur unnecessary costs.
Calculate the total wattage of the devices you want to run. Consider surge power needs for appliances with a compressor or motor, such as refrigerators.
Your backup generator size must match your critical load requirements at a minimum. However, it’s best practice to choose a generator with an output slightly higher than you need, so there’s room to grow if needed.
The EcoFlow DELTA Pro 3 Solar Generator (PV400W) is a good option if you have larger power demands or expect your energy needs to grow over time.
Space Constraints
How much space do you have for the battery component and solar panel in your home? Do you have roof space that allows a permanent rooftop installation, or do you prefer a portable setup you can take down or take with you if needed?
If you want a portable unit, you’ll need storage space and enough room in your car to tote it along on your adventures.

Battery Chemistry and Longevity: Why LiFePO4 Matters
Battery chemistry directly impacts the number of years your generator will last, its safety during charging and storage cycles, and its performance consistency.
LiFePO4 batteries are the best option for solar generators or portable power stations, for many reasons:
Offers 3,000+ charge cycles
Maintains capacity well over time
Performs well in extreme temperatures
Superior thermal stability (reduces the risk of fire)
Disposing of LiFePO4 is more environmentally-friendly than standard lithium-ion
The impressive longevity offsets the higher initial cost
What Is a Standalone Power Station for Home Backup?
A standalone power station is not connected to solar panels but acts as a large battery pack that can charge essential devices. It can deliver energy during outages to keep medical devices, refrigerators, and lights on. Large enough power stations may even be able to run the entire home’s energy needs.
Scalable Home Backup: Planning for More Power with a Larger Battery Pack
Many battery packs are expandable, meaning you can purchase additional batteries to pair together, providing a higher output and storage capacity. You could also opt for a larger power station from the start.
Whatever approach you take, a bigger backup provides better resilience. It future-proofs your investment, extends critical appliance runtime, and can support more devices simultaneously.

Frequently Asked Questions
What Is the Most Reliable Solar Generator?
Reliability depends on battery chemistry, build quality, and the manufacturer’s warranty. The LiFePO4 battery is the most reliable battery chemistry. Look for a generator with this battery, positive customer reviews, and high testing and quality control standards.
Can You Power Your Whole House With a Solar Generator?
A solar generator can potentially power a whole house; it just depends on your home’s size, power consumption, and generator output and capacity. Large units can power most essential circuits, but whole-house backup will require significant capacity. Consider integrating it using professional installation and prioritize your loads to extend runtime.
What Are the Disadvantages of a Solar Generator?
The primary disadvantages of a solar generator are a higher upfront cost, weather-dependent charging, a longer charging time than gas refueling, and battery degradation over many years. Still, the benefits significantly outweigh the drawbacks.
EcoFlow Delivers Reliable, Scalable, and Clean Backup Power
Solar generators, like the EcoFlow DELTA Pro 3 Solar Generator (PV400W), provide a clean, quiet alternative to gas. They’re also sustainable, scalable, and offer long-term reliability. With a diverse product range that meets various needs, there’s something for every power requirement and budget. Consider switching to clean backup power and investing in the future of home resilience.
