We live in a world where warranties matter more than products sometimes. They give you peace of mind, especially when you are making a large investment like a home battery systems
Tesla Powerwall offers a 10-year warranty that too with a guaranteed 70% end-of-warranty capacity. Most homes using Powerwalls, charge and discharge them on a daily basis, and over time, the rechargeable batteries start losing their ability to hold a charge as well as recharge fully.
This isn’t unique to just home batteries, even car batteries need to be eventually replaced. This is why Tesla Powerwall offers a 70% guarantee, which means that your Powerwall will still have 70% (or even more of the original capacity) at the end of 10 years.
Generac PWRcell also has a 10-year warranty. However, it doesn’t guarantee any battery capacity at the end of this tenure. Generac offers a throughput warranty, which means how much energy has been cycled through the battery storage system in MWh. Cars also come with this warranty option. Here the company offers coverage of 100,000 miles or 10 years whichever comes first. In Generac’s case, the warranty is for 10 years or a set amount of energy throughput. This is based on the size of the battery-
The warranty offered by Generac PWRcell is less attractive than Tesla’s as the former offers no guarantee on your battery’s capacity at the end of 10 years. In fact, there isn’t a guarantee that your warranty will even last 10 years in case you reach the throughput amount before that estimated tenure of 10 years. After this, let’s also see the difference in Tesla Powerwall Vs Generac cost.
