As energy independence becomes increasingly important for homeowners, solar battery storage systems have become a crucial part of any new solar system. With 30+ years of experience in renewable energy, Sundance Power Systems provides expert guidance on selecting the best battery storage solution for your home or business. Sundance is truly the regional trailblazer when it comes to battery storage for our solar system.
Battery storage handles critical loads during a power outage, providing peace of mind when the grid goes down. Beyond emergency backup, battery storage can help offset time-of-use pricing that utility companies are using more frequently these days.
Our Renewable Energy Consultants (RECs) are trained to accurately assess your power needs, listen to your goals and design a system that maximizes your energy independence.
Solar batteries have been around for a while, but the technology has grown incredibly in recent years. Homeowners and businesses are seeing the value of solar battery backup as a way to maximize the solar energy generated by their solar panels. Here is an overview of the various battery types. Currently, almost all new batteries use a form of lithium but the older battery types are still a tried and true solution!
Key Battery Types Available in 2025
Today, there are a wide variety of solar battery options available. Each type offers unique advantages, and our expert team can help you select the best option for your specific energy needs: As the market evolves, the best solar battery systems 2025 will likely incorporate advancements in efficiency and storage capacity. By evaluating your energy usage and preferences, you can make an informed decision that not only meets your current needs but also adapts to future growth. Our team is dedicated to guiding you through this selection process to ensure optimal performance and value.
1. Lithium Iron Phosphate (LFP)
Similar to standard lithium-ion chemistry but more thermally and chemically stable, making it safer with less chance of fire. LFP batteries don’t contain nickel or cobalt (avoiding human rights and environmental concerns), and typically have higher peak power ratings and even longer life than standard lithium-ion options.
2. Lithium-Ion (Li-ion)
While more expensive than lead acid batteries, they offer significant advantages:
- Higher depth of discharge, allowing you to use more stored energy
- Longer lifespan due to higher cycle life
- Higher energy density (takes up less room & weight)
- Higher round trip efficiency (less energy wasted)
- Virtually maintenance-free
3. Partial Charge Carbon (AGM)
Absorbed Glass Mat batteries are a version of sealed lead acid battery that tends to be more efficient with greater lifespan and cycle life than traditional lead acid batteries. They typically charge about 5 times faster than flooded lead acid batteries and have a higher charging efficiency, while requiring less maintenance.
4. Sealed Lead Acid Battery (Gel)
More expensive than traditional lead acid batteries but require less maintenance and are considered safer. They tolerate heat better than AGM batteries but do not tolerate fast charging and can be ruined by overcharging.
5. Flooded (Wet) Lead Acid Battery
The oldest type of rechargeable battery with over 115 years of commercial use. It’s the cheapest battery type on the market and is highly recyclable. The disadvantages include low depth of discharge vs cycle life, shorter lifespan, larger size, and requirement for periodic inspection and maintenance.

What factors should I consider when choosing a solar battery?
Consider your energy needs, budget, available space, and what you want to power during outages. Key technical specifications to evaluate include peak power (surge capacity), depth of discharge (DoD), round trip efficiency, retention rate, cycle life, and warranty terms. Our Renewable Energy Consultants can guide you through these considerations.
How does battery storage help during North Carolina’s seasonal storms?
In Western North Carolina, homes and businesses are susceptible to power outages during strong summer thunderstorms and blustery winter weather. A battery storage system provides seamless backup power during these outages, keeping your critical systems running. This means your refrigerator stays on, your lights work, and your water system pump continues to operate.
Can I add a generator to my battery system?
Yes! Many modern battery systems offer generator integration, which means a generator can be integrated to communicate with the inverter to charge the batteries when needed, and/or power the back-up loads when necessary. This creates a comprehensive backup power solution.
How long will a battery system power my home during an outage?
The duration depends on the battery capacity and your energy usage. Our design team performs a thorough load analysis to determine which essential appliances and systems you want to power during an outage. We then size your battery system to provide the appropriate backup duration for your specific needs.
What maintenance is required for different battery types?
Lithium-ion and lithium iron phosphate batteries are virtually maintenance-free. Sealed lead acid (AGM and gel) batteries require minimal maintenance. Flooded lead acid batteries need the most attention, requiring periodic inspection and maintenance including checking water levels and cleaning terminals.
Don’t wait for the next power outage to consider your energy security options. With current incentives reducing costs by up to 52%, solar battery storage is more affordable than ever. Investing in solar battery storage not only enhances energy independence but also maximizes savings on electricity bills. By harnessing the sun’s power, users can take advantage of commercial solar battery benefits, such as reduced peak demand charges and increased resilience during outages. These advantages make solar battery storage an attractive option for both residential and commercial applications.
