Maximum Continuous Power
This metric looks at the maximum amount of power in kilowatts (kW) that can be output at one time. If you think of power as water running through a pipe, the continuous power amount would be dictated by the diameter of the pipe and how much water could be pushed through it at once.
The maximum continuous power rating determines which appliances you can run, since bigger and more robust appliances require more power.
Tesla Powerwall
The Powerwall has a maximum power rating of 5 kW.
Generac PWRCell The stats for PWRCell vary based on which model you choose, from 3.4 kW to 6.7 kW.

Usable Capacity
Usable capacity refers to the maximum amount of energy that can be stored in your battery when it’s fully charged. Using our water pipe analogy again, the usable capacity refers to how much water is available to run through the pipe.
Power and capacity go hand in hand because greater power will provide more energy faster, therefore burning through the total capacity more quickly than a system with less power. Capacity dictates how long your appliances can run for.
Tesla Powerwall
The usable capacity of a Powerwall is 13.5 kWh.
Generac PWRCell
Again, this varies based on the model, from 8.6 kWh to 17.1 kWh of usable capacity.

The Verdict
We vote the Generac PWRCell as the winner, with Tesla Powerwall as a close second. Both of these battery systems are powerful, scalable, capable of charging electric vehicles, and easy to monitor in real-time. They both come with solid warranties and are in similar price brackets.
We chose the Powerwall because it is more of a complete and robust package backed by a trusted brand. However, it really comes down to personal preference, the size of your solar energy system, and any future plans for scaling up your system as to which battery is the best for your needs.
