Level up your solar power with storage

PWRcell 2 is designed to maximize energy savings and bring you peace of mind with clean, reliable backup power. Pair PWRcell 2 with a PWRmicro Solar Microinverter for even more power, greater savings and reliability.

Why Battery Storage

  • Gain energy independence

    Produce, store, and manage your own energy, reducing reliance on an unstable grid.

  • Prepare for power outages

    Store solar power your panels have already harnessed so it’s ready to use during an outage. Add a Generac Home Standby Generator for the ultimate peace of mind.

  • Reduce energy costs

    Switch to stored solar energy to offset peak costs. Plus, use what you’ve harnessed during the day to power your home at night.

 

18 kWh capacity in a single cabinet


PWRcell 2 features one of the highest residential storage capacities available, providing not only additional savings opportunities compared to solar alone, but also up to 33% more backup capability than the current solar storage industry leader.

Powerful alone. Brilliant together.

Adding a Generac home standby generator up to 28 kW provides the ultimate peace of mind and energy independence with virtually endless* backup capabilities. When battery levels get low, the generator will automatically kick on to simultaneously power the home and recharge the battery.

*Subject to fuel availability

   

Harness more of the solar your panels produce

Pair PWRcell 2 Solar Battery Storage with Generac PWRmicro Solar Microinverters and get up to 40% more solar power into your home than with the industry leading microinverters.* *Comparison based on maximum power output of PWRmicro (2 x 410 W = 820 W) versus all residential Enphase IQ8 microinverters.

PWRcell 2 FAQs

Get answers to frequently asked questions about the PWRcell 2 Solar Battery Storage System.

PWRcell 2 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 2 system consists of one Generac Smart Disconnect Switch (SDS), one inverter, at least one battery cabinet, at least three lithium-ion battery modules, one PWRmanager load management device, and an ecobee Smart Thermostat Enhanced.

PWRcell 2 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 capacity is.
  • How much energy (kWh) your home uses over a certain time.
  • How much power (kW) your inverter is rated to push through to your house at a given time.
  • The size (kW) of your solar array. When paired with solar power, your home battery can recharge during daylight hours.
  • Load management capabilities

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 2 is available in configurations from 9 to 36 kWh of battery capacity—your installer can help size the system based on your usage and backup goals.

A home battery like PWRcell 2 enables you to store energy from solar or the grid and use it to power your home at night and during peak demand times when utility rates are most expensive. Compared to solar power alone, when you are limited to offsetting utility costs when the sun is shining.
