Partial Home Backup

Keep Your Essentials Running with Tesla Powerwall Partial Backup

Power your lights, refrigerator, internet, and key appliances during outages without the cost of full home backup.

What is Partial Home Backup?

Partial home backup is a smart way to keep essential systems running during a power outage without powering your entire home. With Tesla Powerwall, you can choose which circuits are backed up, allowing you to focus on what matters most.

Instead of supplying electricity to your entire house, the system is designed to support critical loads such as lighting, refrigeration, internet, and selected outlets. This reduces system size and cost while still providing reliable protection during outages.

What Can You Power with Partial Backup?

A partial backup system is designed to support the most important systems in your home during an outage.

Common Essentials Include:

Lights throughout your home
Refrigerator and freezer
WiFi and internet equipment
Charging outlets for phones and devices
Garage door opener
Security systems

This setup ensures your home stays functional and comfortable even when the grid goes down.

How Tesla Powerwall Partial Backup Works

Tesla Powerwall stores energy from your solar panels or the grid and keeps it ready for use when needed. During normal operation, the system can help reduce electricity costs by optimizing energy usage.

When a power outage occurs, Powerwall automatically switches to backup mode. Only the selected essential circuits receive power, allowing the battery to last longer compared to full home backup systems.

This automatic transition happens instantly, so your home stays powered without interruption.

Why Partial Backup is the Most Popular Choice

Many homeowners choose partial backup because it offers the best balance between cost and protection. Instead of investing in a large system to power the entire home, you can focus on essential needs.

Benefits:

Partial backup gives you peace of mind without overbuilding your system.
