Adding battery storage to your solar system is one of the best ways to increase your energy independence and protect your home against power outages. But with so many options on the market, how do you choose the right battery? At Helio GreenTech, we’re familiar with the best in the business, including Enphase, Sol-Ark Storz, FranklinWH, the new Tesla Powerwall 3, and the 5P battery.

Here’s a breakdown of these options, why they stand out, and what you need to know before adding a battery to your solar system.

Do You Need a Battery to Go Solar?

The short answer is no! Solar systems don’t require batteries to function. In fact, many homeowners start with solar panels and add a battery later. This flexibility allows you to begin saving on energy costs immediately while giving you time to evaluate whether a battery makes sense for your home and goals.

If you’re ready to add battery backup today, you can start with a home backup system for as low as $5,000.
