Residential storage is a fledgling, exciting space right now for solar installers looking to diversify their services or expand. From heavy-duty deep-cycle batteries all the way to full, future-proofed energy storage systems, there are a ton of options in the market to support a variety of customer and installer needs. To help sort through it all, we asked manufacturers in the residential energy storage space to explain what’s new and unique in their offering. Here is what they had to say.
A top solar and battery brand wnow with a full residential energy storage system solution
Product Spotlight: EverVolt
- Simplicity: Only three main components: the inverter, the battery enclosure and the battery modules.
- Flexibility: Comes in both AC or DC-coupled versions and can provide between 11 and 102 kWh of energy storage per system
- Powerful: Can be stacked to provide up to 13.2 kW of continuous back-up power to support pumps, A/C units, and EV chargers.
Panasonic, one of the world’s largest makers of lithium-ion batteries, is taking a universal approach with its EverVolt residential energy storage system. It can be installed with a new or existing solar system and can be tailored to a homeowner’s individual needs. In addition, EverVolt requires only a one-person installation and is field serviceable. It comes equipped pre-programmed time-of-use settings to help manage energy consumption and operating cost, advanced software and a user-friendly app for homeowners, allowing customization between multiple operating modes’ visibility into system status.
What’s unique: EverVolt is available in both AC- and DC-coupled versions. In addition, EverVolt is backed by a 10-year warranty provided by a company with a century-old record of staying power and dependability. While younger battery companies may come and go, leaving customers wondering about the fate of their warranty, Panasonic provides homeowners and installers with the peace of mind that comes with its legacy of reliability.
What’s new: Panasonic announced a strategic alliance with Span, makers of the Smart Panel which is now compatible with Panasonic’s EverVolt. The solution provides flexibility and customization that traditional electrical panels do not, putting monitoring and control for 28 circuits in the palm of the user’s hand via smartphone. When the power goes out, the Smart Panel isolates the house and empowers the customer to control the loads that are most important to maintain power, as well as provides visibility into back-up time and built-in intelligence that optimizes power depending on homeowners’ needs. In addition, the Panasonic alliance with Span simplifies and streamlines installation and labor by reducing the number of components needed by half or more.

Residential energy storage systems that are customizable to fit your energy needs
Product Spotlight: The Electriq PowerPod
- AC and DC-coupled options and On-grid or Off-grid
- 4 operating modes: Rate Arbitrage (Time-of-Use), Self-Supply, Backup, Grid Services/Demand Response
- Stackable: up to 3 inverters (5.5-16.5 kW), up to 34.2 kWh per inverter (11-102 kWh).5-16.5
PowerPod supports autonomous off-grid applications with loads up to 21 kW peak per inverter (16.5 kW continuous). The Electriq PowerPod comes in four different AC or DC-coupled models: the PowerPod 11.4, 17.1, 22.8, 28.5 and 34.2. All PowerPod models are modular, meaning they can be stacked together to create even larger, more powerful battery systems. The largest PowerPod 34.2 boasts a maximum power rating of 5.5 kW to go along with 34.2 kWh of usable capacity. The smallest PowerPod model, the 11.4, offers 4.5 kW of power and 11.4 kWh of usable capacity.
What’s unique: The PowerPod System includes a smart home energy software, Electriq Dashboard, to monitor and control your home’s electricity use and optimize energy efficiency. The Electriq Power app provides analytics and insight on production, consumption, and storage data in an intuitively designed interface. Correlating utility rates, weather predictions, historical consumption, and other factors, Electriq automates savings by controlling the PowerPod to lower energy consumption during peak rates. The Electriq Power app is available on both web and mobile applications, and can be accessed from anywhere in the world through the cloud.
What’s new: Electriq Power offers both in-person and online training programs and customer resources. The PowerPod Certification and Training Webinar is a free certification training and in-depth storage market update for installers. Certification ensures that systems are installed safely and correctly, thereby minimizing the time required for installation, simplifying the commissioning process, and preventing the need for system configuration adjustments post-installation.
