Should you add a Tesla Powerwall to your solar installation?


Whether you experience frequent grid outages, are looking for greater energy independence, or are hoping to maximize savings from your solar system, a Tesla Powerwall can be a great solution to accomplish your energy goals. The Solar Revolution is premier Certified Tesla Powerwall installer in the Boulder Colorado area.



The Tesla Powerwall is a lithium-ion battery that’s most often associated with storing energy generated by Tesla solar panels. However, you can now charge these batteries with any electricity source to use as a backup during a power outage. You can also connect up to 10 Powerwall units as a single energy storage system, making them viable for small and medium businesses as well as homes.


Behind the Powerwall’s sleek, minimalist white casing is one of the highest density residential and light commercial AC battery storage solutions on the market. The Powerwall 2 is a 13.5 kWh capacity rechargeable lithium-ion battery that boasts 7kW peak and 5kW continuous power. Each Powerwall holds 12.2 kWh of usable capacity and maintains a 10% reserve so that when the power goes out, the battery has enough power to turn your solar on to get the battery recharged when the sun comes up the next day. This is enough to run a few lights, keep your freezer from defrosting, and power a few select appliances.

One of the primary benefits of your Powerwall is that it will operate in a grid failure and your home will automatically switch over to the batteries.


If the sun is shining when the grid goes down, your solar system will continue to charge your batteries and stop sending any energy back to the grid. We are required by code to install a “gateway” unit that relays power from your system to the Powerwall and isolates all the power in the house from the grid. This ensures the safety of line workers and is an automatic process when the grid goes out.


If you already have a home solar energy system with its own inverter, the Powerwall 2 is a great option to add energy storage without modifications.


The Solar Revolution has been installing Powerwall’s with new solar systems and adding them to existing solar systems for the last 10 years. If you’ve been following Tesla for a while, you’ll know that their products are in high demand, which can result in delayed supply.
