A whole-house generator, or a standby generator, is a backup electrical system that automatically supplies power to a home during a power outage. Unlike typical generators for houses powered by gas or propane, EcoFlow offers huge 90kWh capacity solar-powered solutions that keep your home running smoothly, rain or shine.
Home Standby
Generator vs.
Home Solar Generator
Solar backup generators for the home harness sunlight through solar panels, converting up to 16.8kW of solar into electricity. This clean energy is stored in batteries of up to 90kWh for backup or energy bill savings. The home generator directly connects to home circuits using a transfer switch or smart subpanel, so when needed, it powers the entire home. Solar generators offer sustainable and reliable power during emergencies or every day to reduce energy bills.
A solar generator is the energy storage for solar energy, converting the DC energy into AC that can power appliances. Solar generators have various outlets, from AC to USB-C, to run an array of devices.
Solar panels capture the sun's rays in photovoltaic cells, then convert the energy into Direct Current (DC). Solar panels come in various sizes and types, including portable and mountable.
EcoFlow Smart Home Panel 2 is the center of our house generator system. With an auto-switchover and power monitoring, this intelligent subpanel offers outage protection and savings in one.
A standby generator automatically activates when a power outage occurs. It uses its own fuel source, like natural gas or propane, to generate electricity and supply it to essential appliances and systems in your home. Once utility power is restored, it switches back to standby mode. It provides seamless backup power during outages.
The ATS is a crucial component that monitors the electricity from the grid and generator. When it detects a loss of utility power, it triggers the standby generator, disconnects the main circuit panel, and seamlessly connects to the generator.
The subpanel is an additional electrical distribution panel connected to the main circuit board. It manages and distributes power from the generator to specific circuits, such as lights, refrigerators, and heating systems, ensuring they receive power during outages.
The main circuit panel, or breaker box, is the central distributor of a building's electricity and connects to the grid and generator through an ATS.
The generator is the heart of the backup power system and converts fuel (propane or natural gas) into electricity. When the main power supply is interrupted, the generator automatically produces electricity to power the connected circuits.
A propane tank holds the fuel source that a standby generator burns to generate. While propane is commonly used due to its stability and long shelf life, natural gas can also be used.

Frequently Asked
Questions
Is it worth getting a whole house generator?
A whole house generator ensures that you and your family have energy security when a power outage strikes. With extreme weather events becoming more common and the aging power grid becoming increasingly unreliable, there has never been a better time to invest in a whole house generator. You can also save on your electricity bills over time — or even eliminate them completely with clean, renewable solar power.
What is the cost of a whole house generator?
The cost of a whole house generator depends on numerous factors. The most critical are fuel type, power output and storage requirements, and how much electricity your family consumes. Gas generators may be cheaper upfront, but generators that offer solar charging with solar panels will save you money on fuel, maintenance, and lifespan in the long run.
Can the EcoFlow whole home generator run on renewable energy sources?
Yes. The EcoFlow whole home generator solution offers up to 1600W of solar charging capacity using portable, rigid, or flexible solar panels (3200W if you connect two DELTA Pros with a Double Voltage hub). How much electricity your whole house generator can provide in a day depends on environmental factors such as how many hours of peak sunlight your home receives. Still, solar generators function even on overcast or stormy days. You also have the option to add the Smart Generator (Dual Fuel), which can run on clean-burning and easy-to-store propane (LPG), as an additional backup charging source.
Can a portable generator power a whole house?
Yes, you can power your whole house using a DELTA Pro portable power station and solar panels. Which configuration is right for you depends on your household electricity consumption and how many appliances you want to run simultaneously during a blackout. If your HVAC systems require electricity, you’ll probably want to invest in the Advanced Kit, 4 - 8 x rigid 400W solar panels, and additional storage capacity with DELTA Pro Smart Extra Batteries.
What kind of fuel does the EcoFlow whole house generator run on?
One of the most significant advantages of the EcoFlow whole house generator is how many charging options it gives you. Using solar panels, you can generate up to 1600W of clean, renewable solar power simultaneously. You can keep your system fully charged between blackouts by quickly charging it with household (AC) electricity. You even have the option to recharge using propane (LPG) and/or gasoline by adding a Smart Generator Dual Fuel to your setup.
How often do I need to perform maintenance on my EcoFlow whole home generator?
One of the many advantages of solar-powered whole house generators is that they require no regular maintenance. Aside from keeping your solar panels free from obstructions and cleaning them every 6-12 months, your EcoFlow whole home generator requires no maintenance, unlike gas generators that need routine upkeep. And because solar is clean and renewable, there are no fuel costs either.
How big of a generator do I need to run my whole house?
Every house is different. There’s no one-size-fits-all generator solution that will work for everyone. That’s why EcoFlow gives you so many options to customize power output and storage to meet your family’s unique needs. To determine how big a generator you need, decide which appliances you want to run simultaneously during a blackout and total up their starting and running wattages. Your generator’s power output capacity must exceed that total wattage — preferably by 10-20%. Looking at your average electricity consumption over the course of a year from your monthly electricity bills is also a good way to estimate how big a generator you need.
Is the whole house generator from EcoFlow easy to install?
The whole house generator solution from EcoFlow is plug-and-play. You can add additional power output and storage capacity — and even a Smart Generator Dual Fuel that operates on propane (LPG) or gas — as easily as plugging an appliance into a wall socket. If you’re using rigid solar panels permanently installed on your roof to generate electricity, you may opt for professional installation. And if you’re integrating your whole house generator with your household wiring with a transfer switch or Smart Home Panel, you may want to hire a professional electrician for half an hour. That’s it.
What happens if there's a power outage while I'm away from home?
You can control and monitor EcoFlow’s whole house generator solution from anywhere with an internet connection using the EcoFlow smartphone app. You can also program your whole house generator regularly to kick in during peak hours to save on your electricity bills. Want your generator to start up immediately during a blackout? You can do that, too — with virtually no interruption to your electricity supply.
What is the expected lifespan of an EcoFlow whole house generator?
The lifespan of any generator is largely dependent on how often you use it. The DELTA Pro portable power station(s) at the heart of EcoFlow’s whole house generator solution can cycle (discharge and recharge) 3,500 times before diminishing in efficiency and 6,500 times before reaching 50% capacity. On average, your whole house generator will last you for 10 years or more and is warrantied for five years.
