Grid-tied solar system with battery backup, or "solar plus storage", is a hybrid system that stays online whether the grid is up or down. All you need to do is capture energy from the sun and store it in a deep-cycle solar battery, then supply that power to either your home or to the grid using a hybrid inverter. This can be especially useful if you are in an area with an unreliable grid due to peak demand or severe weather, or if you simply want to start making and using your own electricity. Browse our selection of battery backup system options below to explore more.
Our battery backup solar power kits have all the major system components needed to generate and store solar power, including solar panels, mounting hardware, batteries, solar charge controller, hybrid inverter, and other balance of system (BOS) components. We have the solar power system kit for you, to meet your energy storage needs!

If you’re going solar with a grid-tied solar power kit, it's worth considering battery backup as well. Grid-tied systems are often the easiest and most cost-efficient type of solar power system to install. However, their main drawback is that when the grid goes down, UL requirements mean grid-tie systems shut down immediately as well. This way your system isn't sending electricity to the grid, potentially endangering lineworkers during an outage.
A hybrid system can take your home off the power grid during an outage. In “island mode,” your home can remain online as an isolated microgrid until utility power is restored. As technology improves, backup power systems have gotten easier and easier to design, install, and maintain. The video below will take you through some of the decisions you’ll make as you begin your DIY project.
Video: How Do You Add Batteries to a Grid-Tied Solar System?
Our video about adding batteries to an existing grid-tied solar system will answer all of your questions about storing your own energy for when the grid is down. Watch to learn more about AC coupled and DC coupled systems!
Generally battery backup doesn't mean powering your entire house. Rather you will identify a few "critical loads" (refrigerator, well pump, select lights, outlet for charging devices, etc.) you want to run in a power outage. Battery backup allows you to have all of the benefits of a grid-tied solar system, and to have power during a grid outage.
The first step is determine your power needs. Check out our grid-tied solar calculator to get started.
We have a variety of DIY solar kits to meet your backup power needs, so you are sure to find a grid-tied system with battery backup for you. What's in a solar power system kit with battery backup? See our high-level list below, or browse the products above to learn more!
Are you looking to add solar battery backup to an existing grid-tied solar power system? We have you covered. Similar to installing a new grid-tied solar kit with battery backup, the first step in getting started is to determine your list of critical loads that you'll want to power during an outage. Check out our calculator to get started on your critical load list.
The new major components you will need in order to add battery backup to an existing grid-tied system—also known as AC Coupling—are a pre-wired AC-coupled system and a battery bank. We also offer DC-coupled systems depending on your needs.
