Lithium Solar Batteries

Lithium solar batteries offer faster charging, longer lifespans, higher efficiency and lower maintenance requirements than traditional batteries. Lithium batteries are ideal for off-grid systems, home backup, RVs, and cabins. Explore top-rated LiFePO4 and lithium-ion options from trusted brands at SolarTown.

Lithium Solar Batteries for On-Site Energy Storage

Whether you're building a fully self-sufficient battery bank to power life off the grid, or simply adding backup power to cover your home during outages, lithium batteries are the most reliable storage solution on the market right now.

Here are a few key advantages of lithium batteries.

No Maintenance

Where other solar batteries require routine maintenance tasks like monitoring state-of-charge and refilling fluids, lithium batteries are maintenance-free. It's by far the most convenient option if you just want your battery bank to work to keep the lights on without constant oversight.

Longevity

Lithium batteries typically carry 10-15 year warranties, compared to 3-7 years on average for flooded or AGM batteries that are properly maintained. In addition, flooded and AGM batteries have a tendency to fail early if they are poorly maintained.

Easier Design and Expansion

In a lead-acid system, cables need to be the same length to charge the batteries properly. Lithium battery banks don't have this restriction. It doesn't matter if you mismatch cable lengths, making it much simpler to design and install a lithium battery bank.

It's also easier to expand on lithium, as the system is modular. If you need more storage, you can add another battery with no issues. You don't need to worry about rewiring the whole battery bank to rebalance the system.

Cost Effective

Lithium batteries have historically been considered the "premium" option for solar. But in the past 10 years, the cost of Lithium batteries has dropped more than 75% - so much that it's now become one of the most affordable options as well.

Their ability to outperform other battery types while staying competitive on cost is a key reason why lithium dominates the solar market today.
