Generac PWRcell Batteries — Modular Energy Storage

About Generac PWRcell

Generac PWRcell is a modular lithium iron phosphate (LiFePO4) battery system designed for residential solar-plus-storage and standalone backup power applications. The system consists of a PWRcell inverter cabinet and stackable battery modules, allowing homeowners to start with a small system and expand as needed. PWRcell is compatible with new solar installations and can be retrofit to existing solar systems through AC coupling.

What sets PWRcell apart from competitors is its seamless generator integration. Generac is the world's largest generator manufacturer, and the PWRcell system is designed to work with Generac home standby generators as part of a complete backup power ecosystem. When grid power is unavailable, PWRcell can automatically start a connected Generac generator to recharge batteries and power the home, providing unlimited backup runtime.

Modular 9-18kWh Storage Capacity

PWRcell's modular design allows configurations from 9kWh to 18kWh of usable storage capacity. The system uses 3kWh battery modules that stack inside the inverter cabinet, with each cabinet holding up to six modules. Most residential installations start with 9-12kWh (3-4 modules) and expand as energy needs grow or budget allows.

The modular approach offers several advantages:

• Start with a smaller, more affordable system and expand later
• Replace individual modules rather than the entire battery if needed
• Right-size storage for actual consumption rather than oversizing upfront
• Add capacity as electric rates increase or consumption grows

Smart Load Management with PWRmanager

The PWRcell system includes Generac PWRmanager, an advanced load management system that intelligently prioritizes circuits during outages. Instead of a simple "all or nothing" approach, PWRmanager can cycle heavy loads like air conditioners, water heaters, and EV chargers to maximize battery runtime for critical circuits like lighting, refrigeration, and medical equipment.

PWRmanager uses smart circuit breakers that communicate with the PWRcell inverter, allowing homeowners to set priority levels for each circuit through the Generac mobile app. During an outage, the system automatically manages loads according to priority and battery state of charge, ensuring essential systems stay powered for as long as possible.

10-Year Warranty

Generac backs the PWRcell system with a 10-year warranty covering the inverter, battery modules, and accessories. The warranty guarantees 70% of original capacity after 10 years, which is competitive with other leading battery systems. As an authorized Generac dealer, Portlandia Electric Supply handles warranty registration and claims on behalf of our customers, providing a seamless support experience.
