Finding the best Backup Solar Batteries for Your Home can be difficult, so we put together this detailed list of the best of the best so you can make your decision wisely. Each battery manufacturer produces batteries with different specifications, from those that offer small batteries meant to power a few appliances to those that offer massive storage laying several days. They also each provide warranties that can vary to suit your needs after the installation process. This list of amazing backup battery manufacturers is ever-changing and expanding, so please check back often. If you find another location that should be listed here – or one that should be removed – please let us know!
1. Electriq Powerpod
Address: 14451 Catalina Street, San Leandro, California, 945777, United States | (855) 250-7097
Product Details: The PowerPod is a smart home battery backup device built to protect against blackouts and save on energy costs. The PowerPod prioritizes keeping batteries charged and ready for grid disruption in Backup mode, using only solar energy. When the grid operation is disrupted, the device will automatically start insulation, and power local loads with solar power or stored battery power.
Key Features: In TOU (Time of Use) mode, the inverter remains grid-connected, but gives priority to the use of batteries and renewable sources to run loads during high-speed periods. Power supplied from the batteries will try to match the load for as long as possible during peak time of use (TOU).
In Self-Supply mode, the PowerPod gives priority first to power local loads with solar and/or stored power. The PowerPod will use the generated solar energy to recharge the batteries before any power is exported to the grid. If the battery is full and there is a surplus of power available, the surplus is exported to the grid. If the battery is exhausted and no solar power is available, power is drawn from the grid to power loads as a last-priority source.
In Custom Mode, you can set discharge and charge periods to match your specific energy lifestyle. Once a schedule has been set, the system will strictly adhere to these periods while unloading or charging. When unloading in this mode, all other modifiers are ignored except for the battery reserve value set by the user and the current charging status of the battery. When charging in this mode, the predetermined periods that are set by the user are the only hours that the battery will attempt to charge up to 100%. This mode is only available on AC-coupled systems.
What Makes Them Different: The Electric Power app provides analytics and insight into the production, consumption, and storage of data in an intuitively designed interface. Correlated utility rates, weather forecasts, historical consumption, and other factors, Electriq View automates savings by controlling PowerPod and other smart appliances to reduce energy consumption at peak rates. The Electriq Power app is available on both web and mobile applications and can be accessed via the cloud from anywhere in the world.

Together, these components ensure that your home enjoys continuous, uninterrupted power – day and night – when you’re connected to the grid or even when the grid is down.
What Makes Them Different: The Ensemble system begins with Enphase Energy AC Modules or IQ Series Microinverters coupled with panels that turn sunlight into clean electricity. Choosing what to do with the energy generated by your PV system is entirely in your hands. You can use the Enphase Enlighten mobile app to:
- Power your home with solar energy right away
- Turn it to the storage of the solar battery for later use
- Feed it to the grid (if your state offers net energy metering)
Seamless integration of Ensemble Technology components allows homeowners unprecedented control over how and when they can use the clean energy generated by their PV systems.
Frequently Asked Questions
1. What are your procedures for ensuring a contactless installation process?
Solar is installed on the roof or the ground, and we already observed social distancing procedures. Our crews wear safety equipment including Personal Protection Equipment to prevent the spread of COVID-19 not only to our clients but also within our crews.
2. How is the sales process if we cannot meet in person?
With just a few pieces of information about your solar project, we can design an online solar proposal for your review. We then set a time to review the proposal by phone or Zoom to answer any questions you have. The financing process is paperless and contactless, any hard copies are sent by Priority Mail/FedEx. All of the contracts and disclosures are contactless using e-signatures.
3. How is the permit process contactless?
Many jurisdictions are starting to allow online permit applications and communication is facilitated by email. Final inspections are still completed in person, but social distancing and PPE are used to prevent the spread of COVID-19.
4. How do we ensure our installation crews are COVID-19-free?
Any of our installers who show up to work with an elevated temperature, coughing, fever, or other sickness, are sent home until the symptoms have subsided.
5. Where can I find more information about COVID-19 and the Solar Industry?
Please check with the SEIA (Solar Energy Industry Association) on all of the latest developments and safety protocols in the solar industry.
