Solar Battery FAQ 

PWRcell is a battery storage system that harnesses power from the sun or the electric grid to help you reduce energy costs, minimize your reliance on the electric grid, and be prepared for unexpected power outages. Every PWRcell battery storage system consists of at least one PWRcell inverter and at least three lithium-ion battery modules in a cabinet. 

PWRcell stores energy from either solar panels or the grid in lithium-ion battery modules. The inverter converts the stored energy from direct current (DC) energy into alternating current (AC) energy which can be used to power your home during peak demand times or utility power outages. 

Generac does not manufacture or distribute solar panels, but our storage solutions are compatible with most panels. Authorized Generac installers can help you select and purchase the right panels for your home, and install the entire system.

How long your battery lasts depends on several factors including how large (kWh) your battery is, how much power your home uses over a certain time, and how much power (kW) your inverter is rated to push through to your house at a given time.

Battery storage system sizing is a critical part of your consultation, so make sure to discuss desired usage plans with your local authorized Generac installer.

PWRcell Solar + Battery Systems offer you the ability to offset your usage of the electric grid. During peak demand times, when utility prices are at their highest, the stored energy can be deployed to power your home, helping you minimize usage of the highest cost energy from the grid.

During a utility power outage, Generac PWRcell provides energy resiliency, by giving you backup power that can be recharged from the sun when the grid goes down. Your system can use stored battery energy to keep your home loads running, and to allow your solar panels to continue to produce power and/or charge your batteries during the day.

Generac is proud to offer the largest energy storage capacity in a single cabinet when compared to competitive products on the market today. One PWRcell cabinet, consisting of six battery modules, offers 18kWh of energy storage capacity. Combine up to two PWRcell battery cabinets, with a total of 12 battery modules, for up to 36kWh of energy storage capacity. 

Each home has unique energy needs. Generac PWRcell offers a modular design for easy customization that meets most customers’ electricity needs. Given the number of configurations available, we recommend that you work with an authorized Generac installer to determine the right size for your home.

Yes! Generac PWRcell Solar + Battery Systems have a modular design that allow you to add capacity as your needs change. You can store as little as 9kWh and up to 18kWh in a single cabinet, up to a total of 36kWh in two cabinets.

Because of the modular design and lightweight components, Generac PWRcell systems are easy to install. Your local authorized Generac installer will be able to give you an accurate estimate for your unique solution, as time varies due to installer schedules, municipal code requirements and other factors. 

The battery is often installed in locations such as the garage, a utility room, or even outdoors. Your local, authorized Generac installer will discuss the best available mounting options for your home and system.

The PWRcell inverter and battery storage cabinet both include a 10-year warranty that covers the cost of parts, labor, and limited travel time for all qualified warranty claims within the warranty period.

Basic maintenance includes cleaning the cabinet exterior with a soft cloth, ensuring the areas near the intake or exhaust vents are free from debris that could obstruct airflow, and removing and cleaning the air filter as needed. Additional service, as required, may be performed by an independent authorized service dealer.
