A PWRcell Solar + Battery Storage system has all the power and capacity you need, enough to save money on energy bills and keep the whole home powered when the grid goes down. PWRcell goes above and beyond the competition with up to 9kW of continuous backup power and cohesive load management for further protection. PWRcell represents the next step in Generac’s 60-year history of backup power technology leadership.
The PWRcell system is not just a powerful battery, but is also the most flexible and scalable home energy system on the market. With a standard Outdoor Rated (OR) battery cabinet, the PWRcell is compatible with most installs in nearly any climate. The PWRcell can also be configured to meet any budget or lifestyle so you don’t pay for more than you need: with as few as 3 battery modules for up to 9kWh of capacity and 4.5kW output, all the way up to our 6-module configuration providing up to 18kWh of capacity and 9kW output. If more power is needed, we’ve got you covered; multiple PWRcell battery cabinets can be connected to a single PWRcell inverter for up to 36kWh of storage capacity and 11kW continuous backup power.

True Energy Independence

The PWRgenerator is a revolution in home energy security, exclusively from Generac. When solar power is unavailable or insufficient, this DC-coupled generator rapidly recharges the PWRcell Battery to keep your home powered long-term during outages. Because PWRgenerators are designed to run more frequently and for longer periods, they are quieter, more fuel efficient, and have extraordinarily long service cycles.

How does it work?

Day: Home runs on solar, charges the battery, and sells extra power to the grid
Night: Home runs on battery power, energy use is optimized
During a Power Outage: Run your home on battery, recharge daily with solar, top-off the battery with PWRgenerator when needed

The PWRmanager advanced load management device adds unbeatable flexibility and value to the PWRcell System by enabling whole home backup, controlled via the user-friendly PWRview app. The PWRmanager enables batteries to work smarter, so fewer batteries can power the home for longer. PWRmanager gives the homeowner flexible access to all loads during an outage while automatically managing loads to extend backup times and prevent inverter overload. This easy-to-install load management device integrates seamlessly with PWRcell, providing reliable power when it’s needed most.

Rated 1 out of 5 by from Buyer Beware Our system with battery back-up went on-line in Sept 2020. It operated perfectly till March 2022, then we started having a series of intermittent and and hard failures with the PVRSS sub-system. All 3 of the SNAP units have been replaced with the latest version, and the S/W has been updated, but we are still having problems. Bottom line, 1/3 to 2/3 of system has been off-line for the past 6 months. Unfortunately, it appears other Generac customers in our area, have been having similar problems. This is not acceptable!

Rated 5 out of 5 by from The product has great fetures , the app needs updating Great product.,. currently have one inverter and two battery cabinets. Would like to see a software update that would allow the App to allow the user to switch operating modes. This would be great especially if your away from the house and need to make changes throuh out the day and evening due to events that may arise. Otherwise its a great system and its saving me boatloads of money on my electric bill.

Rated 4 out of 5 by from Need the tweeks the other customers are talking about. Common sense that the generator should be able to charge the batteries Like the people said in the other reviews, the generator should be able to charge the batteries. And maybe the cover could have some recessed handles , double as vents.

Rated 3 out of 5 by from Low Reliability I own the PowerCell system with 2 Inverters and 18Kwh since Novrmber 2021. Every single month is an issue with one of the inverters, phone customer service take 25+ min to pickup the phone. Once they pickup the phone, be ready to waste 1hr+ of you time. They have "tried" to help with the same exact result everytime, please call the installer. This is a very expensive system so I expect to work flawlessly but it is not. I am regretting to spend so much money in this system. I am selling my excess of power so I am losing money everytime this does not work. So do the math on equipment cost and money loss. I hope Generac fix the issues as I though this was the best system in thr market, at least on paper.

Rated 3 out of 5 by from My system was installed 1st weel of December Our system with battery backup, was installed through Sanctity Solar the first week of December. (Contract was signed June 2021.) However, it has never produced electricity. It appears that there is a problem with the Snaps. But no one really knows as no one from Generic nor Sanctity Solar LLC has cared enough to check out system to ensure that is the problem. I asked about when warranty starts. Generic said for ME to determine if there is a part under warranty that has malfunctioned. I do have 2 Generac portable generators that I have had for years that always start when I needed them. Only had to replace a battery on the one with electric start. Thus, I know that it makes great products. I just need my solar to start working.

Rated 4 out of 5 by from battery back up and recharging Please develop a flexible wrap that can be placed around the battery cabinet and plugged in like an electric blanket so the temperature can be controlled and the batteries / cabinet warmed up on cold days. This would allow the batteries to be charged. My battery back up is outside and it would be nice to recharge them during the colder months. Otherwise, the 9K batteries run the whole house for up to 4 or 5 additional hours after the sun goes down and its a good savings.

Rated 3 out of 5 by from Cold weather charging inadequate We installed a 9 kw system in May 2021. The battery cabinet was placed on an outside wall. Things were pretty good until winter set in, when we noticed the batteries were not always taking a charge on sunny days. After a month of erratic charging and several phone calls, the installer informed us the batteries would not charge when it was below about 45 degrees, and Generac was looking at the problem. Modern Li-ion batteries should operate well below freezing temperatures, although at reduced capacity. It will be disappointing if we get a band-aid solution like relocating batteries into the basement or putting a sleeping bag over the cabinet.

Rated 3 out of 5 by from Solar+ 2 inverters 15kwh system battery back up I just got a 15kwh solar panel system with 2 Generac inverters and the pwrcell. I have it set to sel sufficient. The batteries are 100% charged and it’s now night time yet the home is running on grid power… and there are 0 resources to change it to battery back up scheduled at night. Also the app is awful no help whatsoever. You’d think with the price tag on this product there would be more help on this. Your website. Boasts the app controls the system… the app shows you what’s going on with it kind of. Can’t control anything from the app. No trouble shooting on the app. HOW DO I GET IT SO BATTERY BACK UP AUTOMATICALLY KICKS IN WHEN NOT ON SOLAR!!! You shouldn’t need a tech to come out to do something that should be relatively simple.
