PWRcell
Generac is rolling out new capabilities to its PWRcell product line that turns the promise of whole-home solar backup power into reality.
Yes, Generac’s PWRcell solar and storage system is capable of providing intelligently managed backup power to the entire home, thanks to:
- a PWRcell Automatic Transfer Switch, known as the PWRcell ATS, with integrated load management;
- new higher-capacity batteries rated up to 18 kWh;
- the PWRcell inverter that can now deliver 9 kW of backup power from a single battery pack and up to 11 kW from a dual battery system.
System details
Enabling the entire system is PWRcell ATS, which unlocks the potential to provide whole-home power. While other battery storage systems’ capabilities are usually limited to a few preselected loads during an outage, PWRcell ATS allows Generac’s system to power the entire electrical panel.
In the event of a power outage, the PWRcell ATS disconnects from the grid, allowing the whole home to be islanded as power is routed from the battery and solar array to the home’s electrical panel. Because Generac protects the entire home, the need to move or transfer circuits to a separate sub-panel is eliminated, reducing system complexity and installation time.
To further bolster the whole-home capabilities of the PWRcell system, Generac has unlocked additional power output and is introducing a combination of load management options. With improved performance, the PWRcell inverter can now deliver 9 kW of backup power from a single battery pack and up to 11 kW from a dual battery system. Generac Smart Management Modules work with the load management device built into the ATS to manage all of that power and protect against system overload.
When paired together, the PWRcell ATS and SMMs allow up to 12 circuits to be managed and prioritized. By controlling how power is allocated, the PWRcell system not only keeps all the essentials running, but it provides the opportunity to start larger home appliances like air conditioners and water heaters during a utility power outage, which competing systems can’t handle.
Battery update
Since its introduction in 2019, the PWRcell battery has been one of the most powerful energy storage system available to homeowners seeking energy savings and backup power. Now, Generac is introducing the premium “EX” lithium-ion battery module, which features more battery capacity and improved thermal performance when compared with the standard PWRcell battery modules. PWRcell batteries installed with the optional EX modules will now store up to 18 kWh of usable capacity. The new PWRcell EX modules,
available in early October, allow for higher performance across a broader range of temperatures, making them ideal for outdoor installations.
Beginning in late September, PWRcell installers will also have the option to offer the all-new outdoor-rated PWRcell Battery Cabinet. This outdoor rated enclosure was designed to take full advantage of the improved thermal range of the new EX battery modules and includes additional hardware to help installers get the battery cabinet up and off the ground for easier exterior installations.
With the superior system design flexibility afforded by a single product system, Generac installers can give customers a complete whole-home power solution for the first time. Until now, solar and storage systems have been made of components from multiple companies. Generac entered the clean energy market with an integrated solar and storage solution that outpowered and now out-options the competition.
