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

A balanced energy portfolio at home yields cost savings, energy security and reduced carbon emissions. Produce and use power on your own terms, with or without the grid.

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 and can be recharged with the PWRgenerator
During a Power Outage: Run your home on battery, daily recharge with solar, optimize loads, top-off the battery with PWRgenerator when needed

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.

Rated 5 out of 5 by from Cold Battery We had a system installed and running for about 10 months now. We have a 22kw Generac and solar with batteries. At time of install was told the generator was not able to recharge the batteries, would be nice if it could do that. The system runs well and no complaints, but one. Recently had a problem where the batteries were not recharging during the day. After talking with the techs I learned it's because of the cold weather. Seems when the batteries get below a certain temperature they don't like to recharge. I wasn't told this prior to install or I might have changed the setup. We are having some cold spells here now with freezing temperatures. Today, finally above 50F and the batteries just started recharging.

Rated 4 out of 5 by from Needs a little bit more... Been running PwrCell since March 2021 and tied into solar panels. Works well, minus issues with PV Links. Been having to have them replaced every two to three weeks like clockwork. However, the application needs to have some sort of alerting capability or more user monitoring of the equipment. Great product, just needs a little bit more

Rated 4 out of 5 by from My system has been in for 5 months and so far all is good except for one item The missing feature is the seem less integration of the Powercell with my natural gas Generac Generator. This feature has been promised but a delivery date is always delayed.

Rated 5 out of 5 by from Excelent operation, but lacking some key features I have been running my PWRcell for almost a year with no major issues. The system is very efficient harvesting energy, and it provides whole home backup. There are just two issues that I think must be addressed. First, I would like to charge the batteries from my Generac Propane generator. I cannot understand why this is not happening. Second, the PWRcell app needs a major update. From the app, I would like to change the operating modes and also see again the usage rings in the interface.
