Are modular batteries good for energy storage?

Think of modular batteries as Lego for energy storage. They’re made up of stackable or connectable units, so you can start with the basics and add more when you need extra capacity. No need to buy a massive, expensive battery from the get-go—just grow your system as your energy needs grow. Why Go Modular? How Much Do Modular Batteries Cost?

What is a modular battery system?

The modular design allows each battery module to function as an independent unit, connectable in parallel to boost storage capacity or in series to elevate system voltage. This flexibility enables customization to meet specific energy requirements.

Are modular battery systems scalable?

While modular battery systems are flexible and scalable, they have a few limitations to keep in mind: Having multiple modules means more connections, and this can increase the risk of something going wrong—especially with cheaper systems that rely on lots of manual cabling.

Are modular batteries easy to stack and grow?

Modular batteries might seem easy to stack and grow, but physical placement matters. Avoid putting your battery modules directly under the inverter. If you expand the stack later, relocating components can be a hassle and add to installation costs. Total capacity is also worth considering.
