Generacs Pwrview Monitoring App
Another optional addition to your PWRcell system is Generacs PWRview monitoring app.
Its a one-stop-shop for information about energy generation and usage in your house. The app contains data on solar generation, battery charge, grid usage, and more – and can even give you an estimate of your next utility bill based on that data its collected if you enter your rate plan.
It certainly sounds like a good app to have, and its functionality is similar to other solar monitoring solutions from equipment manufacturers and solar installers. Unfortunately, reviews of Generacs Android and iOS apps are not positive. Users complain about glitches, missing data, bad customer service, and more. This seems to be one area where Generac has stumbled, in regards to its PWRcell system.

The Generac Pwrcell Has Finally Arrived
There has been a lot of companies talking about entering this market and many of them have finally done it or have plans to and some have even left the battery sector, and Ill be cover all of them along with other renewable energy products making there way to homeowners.
Todays video is about a company you may already know, because theyve been around for over sixty years, providing whole home backup to hundreds of thousands of homeowners in the U-S and abroad. Generac, one of the largest generator manufactures, well up until mid 2019, when they acquired Pika Energy and Neurio home link, now theyre one of the largest battery storage manufactures.
Now Ive covered Pika Energy in previous videos comparing their technology to other solar plus storage solutions. And while they werent as well know as the Tesla Powerwall, they were a very competitive and innovative product that we installed in 2019. This new product line up from Generac will be dubbed PWRcell and it lives up to that name.
Its important for me to inform you about this acquisition by Generac because it means better pricing for you as the consumer if youve been holding off on solar and battery storage, but also means you have peace of mind with the product you purchase as the company has been around and is financially stable.
Well see how this pans out long term, but i feel Generacs is going to be planner in the solar plus storage market in years to come.
Powerwall Vs Generac: Dimensions And Weight

The Tesla Powerwall and the Generac PWRcell are not carbon copies of each other when it comes to specific components:
- The Powerwall is more so one cohesive piece, with an integrated solar inverter available.
- The Generac PWRcell comes available in several different configurations, depending on how many battery modules you would like to place within the cabinet.
Parameter | |
115 lbs. | 62.7 lbs. |
If youre going to compare the Powerwall and Generac PWRcell, you need to consider the size of both the inverter and the power cabinet together. You will notice that the Tesla Powerwall is similar to the Generac PWRcell when you combine the inverter and power cabinet dimensions.
The big difference here is the weight. The Powerwall does weigh considerably more than the PWRcell. This weight difference has a lot to do with the simplicity of the Powerwall setup. There are fewer individual components required during the installation of this system than is the case with the Generac PWRcell.

Pwrcell Solar + Battery Backup During Outages And Blackouts

One of the biggest complaints about early solar power bordered on a major drawback of grid-tied systems. During a blackout or power outage, the system shut down the array leaving the house without powereven though the sun shone, and the solar panels continued to produce power.
It is always dangerous and usually illegal to supply power to the grid during an outage. A grid-tie system adds power to the grid whenever an excess of power PV Array produces more power than the home can use. A grid-tie system cannot add power to the grid during an outage, so older systems simply shut down to remain in compliance.
The addition of a transfer switch solves the grid-tie issue. A transfer switch isolates the home from the grid while it produces its own powera major improvement for homeowners tired of power outages rendering their solar panels useless during an outage.
During an outage or blackout, PWRcell uses the PV array during the day to power the house and keeps the batteries charged. When the sun goes down, the system draws on battery power to keep the lights on and the home comfortable.
However, competing systems often shut down the PV array and switch to battery power the moment the power goes out, even though the sun is still shining. When the sun goes down, partially depleted batteries continue to discharge through the night and into the next day.
