The Top Solar Batteries of 2024 and How to Choose the Right One
Solar batteries are a key component of any off-grid solar system, providing a means to store energy generated by solar panels for use when the sun isn’t shining. With the rapid advancement of technology, new battery brands and models are being introduced to the market at an unprecedented rate. However, the best solar batteries are those that enable you to meet your specific energy goals. In this article, we’ll highlight the top solar batteries of 2024 based on popular features and provide some guidance on how to choose the right solar battery for your home.
Best Solar Batteries of 2024
It’s important to note that the “best” solar battery can vary greatly depending on your specific needs. Some homeowners prioritize backup power, others aim to reduce their reliance on grid electricity, and many, especially in California, need battery storage to maximize the savings potential of their solar system. The best solar battery also largely depends on whether you’re installing it with a new solar system or adding it to an existing one. After reviewing the technical specifications of dozens of battery models on the market, we’ve identified a few of the top options for each purpose.
Best Solar Batteries for Backup Power
Backup power during grid outages is one of the most sought-after features of a solar battery. While most batteries offer this feature, a few stand out in 2024.
Franklin Home Power
Quick facts: AC-coupled Lithium Iron Phosphate (LFP) Solar self-consumption, time-of-use, and backup capable
What we like: If you’re looking to back up everything during a grid outage (including central air conditioning), the Franklin Home Power system is a top choice. By combining three 13.6 kWh aPower batteries with a single aGate controller, the Home Power system can provide up to 15 kW of continuous power and 40.8 kWh of usable energy. A single aPower has a peak power output of 9 kW to handle large surges like an AC or freezer kicking on.
Drawbacks: At 408 pounds, a 13.6 kWh aPower battery is significantly heavier than comparable models. It’s also worth noting that 13.6 kWh is the only battery size offered in the Franklin Home Power system, making it difficult to customize the system size.
Solar Self-Consumption, Time-of-Use, and Backup Capable
Solar.com’s top choices for best solar batteries in 2024 include Franklin Home Power, LG Home8, Enphase IQ 5P, Tesla Powerwall, and Panasonic EverVolt. However, the best battery for you depends on your energy goals, budget, and whether you already have solar panels or not.
