What Is a Whole House Generator?
A whole house generator is a backup power system supplies electricity to your entire house during an outage. Connected to the main panel via an automatic transfer switch (ATS), keeping essentials like AC, lighting, and appliances running seamlessly. Unlike portable or traditional standby generators, modern systems whole house generators provide cleaner, scalable power.
The Rising Need for Whole-Home Backup Power
How a Whole House Generator Works
How a Whole House Generator Works
Before an Outage
A whole-house backup generator remains in standby mode, continuously monitoring utility voltage. When grid power drops, the system instantly detects the outage through its automatic transfer switch (ATS).
During an Outage
Within milliseconds, the ATS disconnects from the grid and redirects power from the whole house generator to your 200-amp service panel, ensuring seamless backup for all circuits.
After an Outage
When grid electricity is restored, the system automatically switches back, stabilizes voltage, and returns the standby generator to monitoring mode—preventing surges or interruptions.

FAQs on Whole-House Generators
FAQs on Whole-House Generators
Is a whole home generator worth the investment?
Anker SOLIX whole house generators are designed for homeowners seeking long-term energy security rather than short-term emergency backup. With up to 30kW output, 200A whole-panel coverage, scalable storage up to 90kWh, and flexible solar and multi-fuel integration, it provides full-home protection during extended outages.
Compared to traditional gas generators, it offers quieter operation, lower maintenance, and expandable capacity—making it a strong investment for households prioritizing reliability and energy independence.
How long can a whole house generator run?
A backup generator for home can run from several hours to multiple days, depending on fuel type, energy capacity, and household power demand. Fuel-based generators are limited by refueling cycles, while battery-based systems depend on stored energy and recharge options. For longer, more flexible runtime, systems like the Anker SOLIX E10 Whole-Home Backup Generator extend operation by using modular 6.1 kWh LiFePO4 battery units, high-efficiency power management, and the ability to recharge via solar, grid, or generator bypass—supporting multi-day or continuous backup when paired with renewables.
Can Anker SOLIX whole house generators power a whole home?
Yes. When properly configured, Anker SOLIX can power an entire home through 200A automatic transfer switch capability. With up to 30kW turbo output and high surge handling (275 LRA), it can support central air conditioning, large appliances, and all branch circuits simultaneously. Its modular design allows expansion from 30kWh to 90kWh, enabling multi-day backup depending on household energy consumption.
What appliances can a home generator power?
A home generator can typically power essential appliances such as refrigerators, lighting, internet equipment, medical devices, sump pumps, and heating systems. Larger systems can also support HVAC units, electric cooking appliances, washers, dryers, and well pumps. With 7,680W of continuous 120V/240V output and up to 10,000W of short-term surge power, the Anker SOLIX E10 is capable of running both everyday essentials and high-demand appliances, including air conditioners and other motor-driven equipment.
How big of a generator do I need to run my whole house?
Most homes require 6,000–12,000 watts to run an entire house, depending on HVAC size, cooking appliances, and simultaneous usage. Homes with electric heating or multiple large motors may require more capacity. The Anker SOLIX E10 starts at 7,680W continuous output and uses a modular design, allowing homeowners to add battery or inverter modules to scale power and runtime as needed—eliminating the need to oversize the system upfront.
Is a whole house generator tax deductible?
In most cases, no. However, if the generator supports medically necessary equipment or qualifies under certain energy or emergency-preparedness incentives, partial deductions or credits may apply. Always check with a tax professional for specific eligibility.
Do I need a licensed electrician or permit to install the Anker SOLIX whole-house generators？
Yes. Because a backup generator for house connects to your main electrical panel—often through a 200A automatic transfer switch or Power Dock—a licensed electrician is required to complete the grid connection and ensure compliance with local electrical codes. In many regions, permits and inspections are also necessary.
Once the primary connection is professionally installed, additional battery modules can be added independently to expand capacity, thanks to the system’s modular design.
