Can Tesla Powerwall be Installed Outside? | Powerwall Solar Battery’s Possibility 

Since its introduction back in 2015, Tesla Powerwall has been one of the best solar batteries available in the market for residential use. And although their price can be a bit high, they make up for that with high capacity as well as longevity.

Can Tesla Powerwall be Installed Outside

However, accommodating the Tesla Powerwall can be a bit of a challenge since it requires some wall space. As a result, people often wonder, can Tesla Powerwall be installed outside? Well, the answer is yes. As Tesla Powerwall is rated for both indoor and outdoor installation, you can install the Powerwall outside without any issues. Read on, to find out more.

What Should You Know Before Installing Tesla Powerwall Solar Battery Outside?

Tesla Powerwall is appropriately sized to fit just about everywhere. However, if for some reason you absolutely cannot fit it inside your house, then it can be installed outdoors as well. Here’s why it is ok to install the Tesla Powerwall outside:

1. It’s Weatherproof

One of the great things about Tesla Powerwall is that it’s designed to be weatherproof. Therefore, it has a weather-resistant shell on the outside to protect its interior from harsh weather. Therefore, it’s completely protected against rainfall and corrosion.

The design is complete with a built-in thermal control system. It kicks in whenever the internal temperature exceeds its operating limits or drops below it for that matter. Therefore, you can place it outside without worry and save that space inside your house.

2. Efficiency Concerns

The recommended ambient temperature for Tesla Powerwall is between 32- and 82 degrees Fahrenheit. However, it can still operate between -4 degrees and 122 degrees Fahrenheit. However, when the recommended temperature changes, the thermal controller kicks in. It draws power from the Powerwall to keep it under operating temperature. 

So, when installed outdoors, it may need to run all the time. this will greatly reduce your Powerwall’s efficiency. That’s because by letting the thermal controller run constantly, you are wasting the power that’d otherwise be used to power your home.

3. Wi-Fi Issues

Another thing to keep in mind is that your Tesla Powerwall came with a built-in Wi-Fi connection and it needs to be connected to the Wi-Fi to deliver optimal performance. So, when you install it outside, where the Wi-Fi signal is often very low or weak, you risk getting it disconnected from the internet. therefore, it may not function as well as you expect it to, especially during power outages.

4. During Natural Disasters

As outages happen mostly during natural disasters, getting damaged by any flying debris in a hurricane or the risk of getting submerged in water in case of a flood is a constant worrying factor if you choose to install your Powerwall outside. So, keep that in mind too, if you live in a cyclone, flood, or snowstorm-prone area.
