FAQs
Please read our FAQs page to find out more.
What’s the difference between a standby generator and a portable generator?
A standby generator is permanently installed outside your home and automatically powers your entire house during an outage. Portable generators are smaller, movable, and best for running essentials or outdoor needs.
How do I choose the right generator size?
Start by calculating the wattage of the appliances you want powered. Smaller homes may need 10–14 kW, while larger homes often require 18–26 kW or higher. Portable units range from 2,500–18,000 watts.
Do generators need professional installation?
Standby generators require professional installation with a transfer switch for safety and compliance. Portable generators typically do not — they can be set up manually with extension cords or an inlet box.
What fuel options are available?
Most standby generators run on natural gas or liquid propane. Portable units are available in gasoline, dual-fuel (gas/LP), tri-fuel (gas/LP/natural gas), and diesel.
Do Generac generators come with warranties?
Yes — Generac offers a 5-year limited warranty on residential standby models, with extended options available. Portable models also include manufacturer warranties.

What’s the benefit of a home battery system?
Home batteries store solar or grid power for backup use, reduce reliance on the grid, and can help lower energy bills by shifting usage to off-peak times.
Can Mango Power and Lion Energy batteries power my whole home?
Yes. Mango Power systems offer whole-home backup with modular expansion. Lion Energy’s batteries are stackable, making them ideal for growing energy needs.
Do batteries work without solar?
Yes. While batteries integrate perfectly with solar, they can also charge directly from the grid to provide backup during outages.
What warranties do home batteries include?
Tesla, Mango Power, and Lion Energy all offer 10-year limited warranties, ensuring long-term performance.
