The ZB30K provides enough energy to power all your appliances and HVAC up to a full day during power grid disruptions and up to a week without *HVAC. With enough installed solar panels you could run essential items for years.
The ZB30K connects to a **Safety Transfer Switch installed by a licensed electrician near your main circuit panel and stays fully charged when your power is on.
When the power goes out, the Safety Transfer Switch cuts the connection to the grid and allows power to flow from the battery into your Main power box. It happens so fast (usually within a second) you probably will not notice.
**Air conditioning and/or furnaces
**This is for the safety of utility linemen that may be working on lines near your house and prevents the power from your battery to provide power to the electrical lines leading to your home.
