Can You Add Batteries to Your Existing Solar System?

If you’re in Columbus or the surrounding areas and already have solar panels on your home, you might be wondering: Can I add batteries later on?

The answer is: usually, yes.

We’ve retrofitted dozens of solar systems across Central Ohio with backup battery storage. At BC Solar, we make sure the process is smooth, honest, and tailored to your exact system — no unnecessary upgrades, no upselling.

How It Works

Adding batteries to an existing solar setup depends mostly on one thing: your inverter.

• If your inverter is compatible, we can likely add batteries with minimal changes.

• If your inverter isn’t compatible, we’ll upgrade it or add an additional hybrid inverter that works with your battery bank.

Not sure what kind of inverter you have? No problem. We’ll inspect your setup and give you a clear, no-pressure explanation of what’s needed — and what’s not.

We’ve done this for everything from small 5kW residential systems to larger homes with complex electrical setups.

Why Add Batteries?

If your home already produces solar energy, batteries can take your system to the next level.

Here’s what you gain:

• Backup power during outages — no flickering lights or spoiled food.

• More control over your energy — store extra power for evening use.

• Peace of mind — your home stays powered even if the grid doesn’t.

Columbus homeowners are increasingly asking for battery storage — especially after experiencing grid instability, harsh weather, or just wanting more self-reliance.

What We Won’t Do

At BC Solar, we don’t play the sales game. We won’t recommend a $15,000 upgrade if a $1,200 inverter retrofit does the job.

We believe in doing the right thing — because it’s the right thing.

So whether you need:

• A small Enphase retrofit

• A full Sol-Ark battery-centered rebuild

• Or just some honest guidance

We’ll walk you through your options and give you straightforward pricing.

FAQs

Can you retrofit any solar system with batteries?

Most systems can be retrofitted, but some require inverter upgrades. We’ll assess yours and give you clear guidance.

What types of batteries do you install?

We’re battery agnostic. We install Sol-Ark, EG4, Fortress, and other top-rated lithium battery systems depending on your needs.

Will I still be connected to the grid?

Yes — unless you want to go off-grid. We specialize in grid-tied battery systems that give you backup power and let you benefit from net metering when available.

How much does it cost to add batteries?

Costs vary based on your system and needs. Most homeowners spend between $7,000–$14,000 for batteries and a compatible inverter. We’ll give you a custom quote with no pressure.
