The PWRcell battery is not only the most powerful battery on the market, it is also the most flexible and scalable. It can be set up for completely outdoor installations in nearly any climate with the optional  Outdoor Rated (OR) PWRcell battery cabinet and new PWRcell battery module. The PWRcell battery can be configured to meet any budget or lifestyle: with as few as three battery modules for just 8.6kWh of capacity and 4.5kW output; or, four, five and six battery module configurations yield more power and capacity up to 18kWh capacity and 9kW output. When even more power is needed, multiple PWRcell batteries can be connected to a single PWRcell inverter for up to 36kWh of storage capacity and 11kW continuous backup power.

Rated 5 out of 5 by from Overall, I'm impressed. I was looking at options for back up power here in hurricane country and didn't want some loud and dirty gas powered lawnmower engine and ended up going with solar panels and Generac PWRcell back up system. The install was as smooth as it gets, the crew was great. The Generac products are easy to understand and operate. I really don't know what else to say. I'd done my homework last year looking at propane fired generators but took a few months to think about and decided solar was the best way to go. Why pay an electric bill if you don't have to. These systems are not cheap, but reducing or eliminating an electric bill is just smart and green, and solar batteries keep charging when the power goes off, so... Not looking forward to the next weather even that knocks out my power, but this time I will be ready.

Rated 4 out of 5 by from Just installed so not a complete rewiew. The installation took 2 days and the installers just left yesterday and my unit is not up and running yet so all I can review is the installation. The crew showed up as schedules and each of the crew seemed to know their role and went to work right away. All the men and the woman worked at a team to complete the installation as schedules. Now I wait for the inspections and the power company to change out my meter and activate my solar unit. It is a very complex system so I just hope it works as efficiently as promised without too much control on my part.

Rated 5 out of 5 by from Smart Battery System We love the PWRcell because it takes the "storage' and 'backup' conversation to a new level. This is a energy cost management tool as well with it's TOU management through it's app. AND if you have AC, and you want it to start on backup power, good luck. You NEED the Generac with its 50amp surge.

Rated 3 out of 5 by from Poor warranty service System controller was bad from factory dealer. Wall battery could not be integrated with solar panels due to bad controller. It has been 3 weeks since problem was identified and unit arrived today to my installation company. It will be changed out next Tuesday. I will let you know how well it works soon. I would have expected it to be sent next day air to my installer. I hope it was tested before sending it out.

Rated 3 out of 5 by from Regrettable decision My Generac batteries (2.85 kWh), don’t last past an hour on self supply. My electric company has a peak time in summer and another one in the winter. There are zero setups that I can use so I don’t have to go out twice a day daily, to change the setup. There is a similar setup but it doesn’t include weekends. I can’t get anyone at Generac to work with me to setup a program for me so I don’t have to manually manipulate the inverter twice a day. So besides the fact that the batteries don’t last past an hour (the HVAC not running) and having to manually control the inverter, sure it’s a very impressive ornament.

Rated 5 out of 5 by from Super Installation and neat and clean appearance I just had my Generac PWR Cell and inverter installed. the installation was fantastic. the service techs and electricians were fast friendly and the attention to detail was great. the options that I have as far as visual and remote control over every aspect of usage is fantastic. the monitor allows for easy set up and functionality by anyone with ease. thanks for a fantastic product, im sure it will serve me well Mike
