Choosing the Right Backup Power Solution for Your Residential Solar System

In today’s world, where electricity has become an indispensable part of our lives, ensuring a reliable power supply is crucial. For homeowners with solar systems, having a backup power solution is essential to maintain electricity during grid outages. At Supreme Solar, we understand the importance of backup power, and in this blog post, we will delve into the two primary options available: partial home backup and whole home backup. By understanding these options and their advantages, you can make an informed decision that aligns with your specific needs and budget.

Partial Home Backup

Partial Home Backup Explained: Partial home backup refers to backing up specific appliances and critical loads during power outages. This option is ideal for homeowners who want to ensure essential functions continue running, such as lights, refrigerators, garage doors, and Wi-Fi outlets.

Home Batteries as a Solution: To achieve partial home backup, home batteries or energy storage systems are commonly employed. These batteries operate on direct current (DC) and need to convert it to alternating current (AC) for household use. However, it’s important to note that the inverter inside the home battery limits its capacity for partial home backups.

Critical Load Panels: In a partial home backup setup, critical load panels play a vital role. These panels are connected to the home battery and allow you to select the specific appliances that will receive backup power during an outage. By connecting critical loads, you can ensure that essential devices and systems continue functioning until grid power is restored.

Whole Home Backup

Whole Home Backup Explained: Whole home backup provides a comprehensive solution by backing up the entire home, including larger appliances like air conditioning units, ovens, and other power-intensive devices. This option ensures that all electrical systems and appliances operate seamlessly during grid outages.

Generators for Whole Home Backup: To achieve whole home backup, generators are the go-to solution. These devices range in size from 14 to 22 kilowatts, depending on the power requirements of your home. They can be powered by either gas or propane, providing flexibility based on your fuel preferences and availability.

Automatic Transfer Switch (ATS): An essential component of whole home backup systems is the automatic transfer switch (ATS). This device monitors the power supply from the grid and automatically switches to the generator when an outage occurs. This seamless transition ensures that all appliances and systems receive uninterrupted power during blackouts.

Choosing the Right Backup Power Solution

Determining Your Power Requirements: Before selecting a backup power solution, it is essential to evaluate your power requirements. Consider the appliances and systems you want to back up during an outage. This assessment will help you determine whether a partial home backup or a whole home backup is the most suitable option for your needs.

Weighing the Pros and Cons: Both partial home backup and whole home backup have their advantages and limitations. Partial home backup is more cost-effective and focuses on critical loads, while whole home backup ensures a comprehensive backup solution but comes at a higher price point. Consider your budget, lifestyle, and specific backup needs to make an informed decision.
