Solar inverter repairs: When to DIY and when to call the pros
Generac knows power better than anyone. That's why they have dominated the residential backup power market for 60 years and are continuing to lead. Building on decades of home backup power expertise, Generac is the leading global supplier of solar energy storage systems, backup power, and prime power products. Since 1959, Generac has grown its product offering from the largest home generator brand into a broad range of innovative clean energy products.
The company's PWRcell inverter system represents a breakthrough in residential energy storage, combining solar power conversion, battery management, and backup power capabilities into a single integrated platform. Introduced in 2019, the Generac Pwrcell has quickly ascended as a leading name in the solar battery market. It's crafted to simplify the process for homeowners to identify and acquire the precise battery size they require based on their energy consumption.
🔋Battery Integration
The PWRcell battery can charge from solar, the grid, or even one of Generac's home standby generators, allowing you to keep the power on for extended periods of time during an outage. Modular design ranges from 9-36 kWh storage capacity.
⚡Power Performance
PWRcell offers 30% more power output than our competitors (figure based on single storage cabinet of battery modules), and it offers more storage capacity, so you can run more than just the essentials. Up to 11 kW continuous backup power available.
🏠Smart Home Integration
With the Generac Smart Management Modules, homeowners can literally determine priority levels in terms of what gets access to energy at predetermined times. If a homeowner wants larger appliances, like an air conditioning unit, to continue to receive power, the Smart Management Modules can make that happen rather than electricity being sent to power outdoor lighting.
🛡️Generator Compatibility
Native integration with Generac standby generators provides extended backup power capability during prolonged outages. No other major battery system offers this seamless generator integration.
The Generac PWRcell inverter operates as the central hub of an integrated energy management system. The Smart Disconnect Switch (SDS) is like a central hub where everything comes together. It connects between your home's meter and main electrical panel (up to 200A), as well as the battery, AC solar panel output, and even a backup generator. Thanks to the SDS, which can combine the power output of any or all of those sources, the PWRcell system can keep your home running during a power outage.
The Generac three phase hybrid inverter utilizes proprietary REbus technology, operating at a fixed 380 VDC. This bi-directional, REbus-powered inverter offers a simple, efficient design for integrating smart batteries with solar installations. Boasting a commendable round-trip efficiency of 96.5%, the Pwrcell ensures that only a minimal 3.5% of electricity is lost during storage.
The PWRview monitoring app features comprehensive system oversight through real-time data tracking. While the PWRcell's intelligence automatically manages home energy to optimize efficiency and performance, you can monitor the performance of your battery on the PWRview app with real-time data. Generac also has an app called PWRview that allows you to control the system.
The Generac 7.6kW single phase inverter serves as the foundation for most residential installations. This model provides 120/240-Volt AC output with islanding, grid sell, prioritized renewable charging, zero export, and self supply modes. It has a peak power output range between 4.5 kW and 9 kW and a consistent power delivery between 3.4 kW and 7.6 kW.
The Generac three phase hybrid inverter addresses larger residential and small commercial applications requiring three-phase power delivery. The 11.4kW three-phase grid-tied inverter integrates REbus DC nanogrid technology with comprehensive monitoring capabilities.
Generac solar inverter with battery storage systems offer unparalleled flexibility. By providing a number of options and modular capabilities, the Generac PWRcell address the capacity and power needs of a wide range of clients. Not all storage systems provide this many options or this kind of flexibility. The Generac PWRcell is not the only modular system available on the market, but it is one of the few that offers enough flexibility to become "off grid" if desired. A modular system allows clients to purchase additional storage or capacity units to provide increased storage and dispatching solutions even if the utility grid goes down. With the modular capabilities of the Generac PWRcell, clients looking to be energy independent or entirely "off grid" can do so if they purchase the right amount of equipment.
PWRcell inverter installation requirements mandate certified installer training for warranty coverage. PWRcell is also fully integrated and lightweight, making installs faster and more efficient. Each component weighs 75 lb or less and is designed to work seamlessly with the rest of the system.
Generac inverter warranty coverage provides comprehensive protection through a 10-year warranty on all major system components. Covering parts, labor, and limited travel PWRcell Battery Cabinet, 10 Years PWRcell Battery Modules, 10 Years or 7.56MWh of energy throughput per module, whichever comes first PWRcell Inverter, 10 Years PWRmanager, 10 Years PV Link, 25 Years SnapRS, 25 Years PWRgenerator, 5 Years Limited
If you're a homeowner looking for a backup power solution in case of a power outage, the Generac PWRcell should be on your shortlist. We put it in the #9 spot on our Best Solar Batteries of 2025 list. However, some customers have experienced challenges. It may be difficult to get through to Generac customer service however they do pay attention to their customers... They have since reached out and is actively working to ensure my system is functioning normally.
If you prioritize power and capacity, then look no further than the PWRcell. Since power and capacity go hand in hand, the PWRcell yields the best of both.

Yes, Generac PWRcell systems uniquely integrate with Generac standby generators, providing extended backup power during prolonged outages when solar generation is insufficient.
The Generac PWRcell 2 is a home energy storage system that can provide whole or partial home backup power. This is the second generation of Generac's popular home battery solution, and the new version offers extra power output and new home integrations.
A typical Generac PWRcell 2 system costs between $14,000 and $25,000 before incentives. The system includes a modular battery cabinet, inverter, and smart disconnect switch for partial or whole home backup.
The PWRview app provides comprehensive system monitoring with real-time data tracking, consumption analysis, and battery status updates accessible from any smartphone or tablet.
AC-coupled only, meaning any solar installation must have its own inverter in order to connect and charge the PWRcell batteries. This allows compatibility with most existing solar panel systems.
