How to choose the right battery system
Evaluate Battery Specifications
Compare factors like battery capacity, continuous power output, and on-grid vs. off-grid power output - understand the differences in performance and backup capability
Consider Battery & Installation Cost
Once you understand how different batteries stack up from a performance standpoint, compare the cost - ensure the relative price tags are in line with relative performance
Compare Warranty Coverage
Ensure your investment is backed up by solid warranty coverage - most battery manufacturers offer a 10-year warranty against material defects
How many battery modules do I need?
How to calculate the right number of BATTERIES for your system
Determine How Much You Want To Back Up, And For How Long
Identify What You Want to Back Up
The first step to determining how many battery modules you need for your home is to decide exactly what you want to back up, and for how long.
Understand How Your Main Panel Affects Battery Use
We guide you through unlocking local rebates, and answer your questions about the 30% Federal Tax Credit helping you reduce upfront costs and maximize long-term savings.
Estimate Duration and Power Usage
Once you’ve chosen the circuits you want to back up, consider how long you’ll need to run them on backup power. Just like a phone battery drains faster when streaming video, a backup battery will drain faster or slower depending on how much strain is placed on it.

Calculate how much power your backup circuits will need over your desired backup time
Once you’ve decided which circuits you want to back up and for how long, the next step is to calculate the total power demand.
For example, if you want to back up your EV charger, air conditioner, refrigerator, and your home’s lights and outlets for 4 hours each evening to avoid peak demand charges, you’ll need to know how much power each one uses per hour.
Keep in mind that actual backup time depends on how much energy you use. Running multiple large appliances at once will drain batteries faster, while careful usage will extend backup time.
The same method can be used for other backup setups: total the power usage of each device, multiply by how long it runs, and you’ll get a good estimate of how much battery storage you need.
Make sure your solar system can
fully charge your batteries
If you already have solar, check how much excess energy you generate and whether it’s enough to charge the batteries for your backup needs. You may need to add panels to meet your goals.
If you’re installing solar with your battery system, ensure the system is sized to cover your daytime use and charge the batteries adequately
