Frequently asked questions
Do I need an electrician to install a whole home backup system?
Systems that connect to your main panel, a smart panel or a transfer switch should be installed by a licensed electrician to meet local code. Plug-in setups that use an inlet box need less work, but a professional check is still recommended.
Can I add more batteries later?
Yes. These systems are modular, so you can start with the capacity you need and add compatible expansion batteries later.
How long does shipping take?
Orders ship free within the United States and arrive in 4 to 6 business days.
