Best for Essential Home Appliances: EcoFlow DELTA 3 Max Plus (2048Wh) + 400W Solar Panel
Best Home Backup Generator for Apartments and Small Homes: EcoFlow DELTA 3 Ultra Plus (3072Wh) + 500W Solar Panel Kit
Best Whole-Home Generator: EcoFlow DELTA Pro Ultra X

Best for Entry-Level Backup: EcoFlow DELTA 3 Classic (1024Wh) + 220W Solar Panel
EcoFlow DELTA 3 Classic (1024Wh) + 220W Next Gen Bifacial Portable Solar Panel is the perfect entry-level solar generator solution both for home and recreational use off-grid.
DELTA 3 Classic (1024Wh) is the most affordable entry point into EcoFlow’s new DELTA 3 Series of solar generators and home backup battery systems.
With 500W of solar charge input, you can connect up to two EcoFlow Next-Gen 220W Bifacial Portable Solar Panels.
Or you can max out your solar input with 5 x EcoFlow 100W Portable Solar Panels.
Either way, you get a ton of bang for your buck.
With 1800W of AC output (3600W) EcoFlow DELTA 3 Classic can start and run most high-wattage home appliances, like refrigerators, televisions, space heaters and window or portable air conditioners.
However, it lacks sufficient power output and battery storage capacity to run multiple heavy duty appliances simultaneously during extended power outages.
Most blackouts only last a few hours, in which case you can keep your refrigerator running and your smartphones charged for the duration.
Want to watch some TV while you’re waiting for the power to come back on?
No problem.
Just remember to plug your wi-fi router into your EcoFlow DELTA 3 Classic (1024Wh) as well as your television and stream your favorite shows even during a power outage.
If you leave the portable power station connected to a household wall outlet, it will pass through grid power and automatically switch on during a blackout, ensuring you always have a full charge.
EcoFlow DELTA 3 Classic (1024Wh) is also ideal for home office use.
Desktop computers, external hard drives, and other precision electronics are extremely sensitive to variations in the supply of grid electricity, such as voltage drops and brownouts, let alone power outages.
Surge protector power strips offer limited protection against sudden spikes in power, but do nothing to mitigate the impacts of blackouts or brownouts.
Uninterruptible power supply (UPS) units are rechargeable battery devices that plug directly into grid power using a standard household electrical outlet, and sit between your computer, peripherals, or other devices which you must connect directly to the UPS.
Connecting a power strip or surge protector to a UPS is never recommended because it diminishes the protection the unit offers.
UPS and portable power stations for desktop computers and external hard drives should have an auto-switchover of 10 milliseconds or less (<10ms) to provide data center level protections against voltage and current variations or blackouts.
EcoFlow DELTA 3 Classic offers 10ms auto-switch UPS protection and with 1kW of battery storage, you can run your computer, peripherals, and router for hours during an outage.
Consumer UPS solutions typically only provide about 10-20 minutes of power before the battery runs out. If you’re at your desk when the lights go out, that should be enough time to shut down your computer and peripherals down properly which should prevent data loss and damage from the blackout.
However, if you’re not home and your computer is on, the UPS offers little protection. When the battery runs out, your computer won’t shut down correctly, unless the UPS provides specialty software and connects to your computer with a USB cable or other method.
Whether you need a solar generator for essential home appliances or a UPS for your home, EcoFlow DELTA 3 Classic is an affordable way to get both.

It’s easy to see why so many solar panel and home battery buyers are taking advantage of expiring clean energy credits before it’s too late.
Even If you don’t owe any income tax this year, or the amount of your credit exceeds your current tax bill, you can apply the non-refundable tax credit to future liabilities.
And the government incentives don’t stop there. Depending on your location, there are many state solar incentives, as well as those offered by utility companies and municipalities.
Make sure to take full advantage of the available programs that reward your family for switching to clean, renewable solar power.
The Residential Clean Energy Credit was originally scheduled to run until 2032.
However, the One Big Beautiful Bill Act now ends Federal solar tax credits as of December 31st of 2025.
Qualified Clean Energy Property purchased and installed on or after January 1st, 2026 will no longer receive the credit, even if it meets all the previous eligibility criteria.
Many US homeowners are rushing to install solar in 2025 so they don’t miss out on the substantial savings and maximize their return on investment.

What Is a Solar Generator?
A solar generator consists of photovoltaic (PV) modules — typically solar panels — and a balance of system that converts (and sometimes stores) AC and DC electricity.
A balance of system can be made up of discrete but compatible components or housed in an all-in-one unit like EcoFlow’s portable power stations.
A typical off-grid or hybrid residential solar power system includes:
Solar panels
Solar inverter
Solar battery
Solar charge controller (MPPT or PWM)
Transfer switch or Smart Home Panel
Mounting hardware for solar panel installation
Cables and wiring
An on-grid system has less components, but it won’t work in a blackout without battery storage.
Speaking of on and off-grid, there are three basic types of solar generators.
Off-Grid
Off-grid solar power systems generate electricity solely using solar panels and do not connect directly to the grid.
Solar power is intermittent by nature. You’ll generate less power on cloudy days and solar panels don’t work at night.
Off-grid solar solutions like EcoFlow DELTA Pro Ultra X store electricity in a solar battery to draw on during hours when little or no power is produced.
Although off-grid solar power systems don’t connect directly to the utility grid, many offer AC and DC charging capabilities.
Grid-Tied
Grid-connected solar power systems do not require storage.
A traditional on-grid solar system utilizes solar panels and an inverter, and a bidirectional meter to transmit and receive electricity from the utility grid.
A solar inverter is a necessity in all solar power systems because photovoltaic modules capture photons from sunlight and convert them into DC electricity. The inverter converts DC electricity to AC for use in your home and for the grid.
On-grid systems have their advantages. However, without storage, a grid-tied system won’t work during a power outage.
Hybrid
A hybrid solar power system, like EcoFlow DELTA Pro Ultra X, offers on-grid connection for charging and solar battery storage.
With a hybrid system, you get all the benefits of grid connectivity and the energy security of off-grid.

How Do Solar Generators Work?
All modern residential solar generators that produce electricity operate using the same basic principles.
Photovoltaic modules — typically solar panels — capture photons from sunlight and convert them into DC electricity.
The active component in solar panels are photovoltaic cells — usually monocrystalline or polycrystalline silicon — that generate electricity from solar irradiance (sunlight) using the photovoltaic effect.
PV modules transmit power to the solar inverter which converts DC electricity to AC for use in your home — and potentially for transmission back to the grid through a net metering program
If your solar generator stores electricity, DC power is sent to a charge controller and solar battery.
A hybrid solar power system offers both storage and grid connectivity so you benefit from the advantages of both.
What To Consider When Shopping for the Best Solar-Powered Generator for Home Backup
No matter what type of residential solar generator you’re looking for, there are numerous factors to consider before making a purchase decision.
Here are the most crucial:
Household Electricity Consumption
It is essential to accurately determine the total running and starting wattage of all the devices and appliances you want to run simultaneously with electricity produced by your solar generator.
You can get a ballpark estimate of your daily electricity consumption by dividing a recent electricity bill by 30 days. However, this is not something you want to guesstimate.
Learn how to calculate kilowatt-hour consumption for your home.
On-Grid, Off-Grid, or Hybrid?
Next, you need to make a decision about what kind of solar power system you want.
If you’re unconcerned about power outages and live in a location that offers net metering, you might consider a traditional on-grid solar power system.
However, with extended power outages occurring ever more frequently, investing in an off-grid or hybrid solar power system offers far more energy security.
AC Output
AC Output refers to the maximum amount of electricity a generator can produce on demand.
At a bare minimum, the AC output of your solar generator should exceed the combined wattage of all the appliances you want to operate simultaneously by at least 10%
Don’t forget to consider starting watts!
Many high-wattage appliances — particularly ones that use motors like refrigerators and washing machines — require significantly more power to turn on than they do to operate.
Thanks to proprietary X-Boost technology, EcoFlow’s solar generators offer up to double their operating AC output as surge power.
Storage Capacity
If you have an off-grid solar power system, battery storage capacity will determine how long you can run your appliances during the night or other times of day where your consumption exceeds your production of electricity.
Capacity is less of a concern for hybrid and grid-tied systems because they can access grid power during a shortfall. Except during a blackout.
Number of Solar Panels, Rated Power, and Efficiency
Every solar panel comes with specs for rated power in watts and efficiency.
For example, EcoFlow’s 400W rigid solar panel produces 400 watts of electricity per hour under Standard Test Conditions and offers industry-leading 23% efficiency.
Standard Test Conditions for Solar Panels
Condition Type  | Standard Test Condition  | Real-World Conditions  | 
Solar Incident Angle  | Always zero, irradiation beam always normal to the PV panel*  | Variable, and depends on time, date, and site latitude. In the case of rooftop systems, roof orientation, and inclination govern system capacity.  | 
Solar Irradiation  | Always equal to 1000 Watts/m²*  | Variable and depends on the time, date, and site latitude. Limited sunshine hours bound system capacity.  | 
Ambient Temperature  | Always 25°C*  | Variable and depends on the time, date, weather condition, and site latitude. Higher ambient temperature degrades PV panel efficiency and reduces system output.  | 
Air Mass Coefficient (AM)  | Always equal to 1.5*  | Variable and depends on the time, date, and site latitude. Higher AM with higher latitudes.  | 
System Losses (e.g., Wiring, Inverter)  | Always Zero*  | Variable and depends on the design and location of PV panels, inverter, and grid meter.  | 
*Cannot be achieved in real-world operation (Source: ResearchGate)
Real-world conditions rarely (if ever) match Standard Test Conditions. Even highly efficient solar panels will produce less than their maximum rated power for many hours of the day.

Peak Sunlight Hours
The number of hours of peak sunlight your solar panel installation receives has a significant impact on your electricity generation potential and varies widely based on location.
Available Surface Area for PV Module Installation
To maximize electricity production, you must install your solar panels in direct sunlight.
For most homeowners, a rooftop installation makes the most sense. However, ground installations can also be viable.
Ensure that you position your solar panels facing south. Carefully determine the ideal angle and tilt relative to your location relative to the position of the sun.
Budget
Last but not least, you need to weigh up how much you can afford to spend on a solar generator vs. your long-term return on investment.
With many government solar incentives available, it’s possible to substantially reduce your purchase cost.
Additionally, there are often low-to-no interest rate financing options if you purchase your solar generator direct from the manufacturer.
The sooner you achieve solar payback by recouping your initial purchase and installation costs, the sooner you start making money on your investments.
Solar panels last for decades.
Make sure to invest wisely, and you’ll reap the benefits for many years.
Frequently Asked Questions
Can Solar Generators Power a House?
Yes. If you purchase a solar generator with enough AC output and storage, it can power your home off-grid indefinitely. You also need to buy enough solar panels to meet your electricity production needs. Make sure to carefully assess any photovoltaic modules’ rated power wattage and efficiency. Factor in the peak sunlight hours at your location.
