Tesla Powerwall Capacity: Understanding the Ah Rating
Introduction to Tesla Powerwall Capacity
The Tesla Powerwall is a popular home battery system designed to store excess energy generated by solar panels or the grid, providing backup power during outages and reducing energy bills. One of the key specifications of the Powerwall is its capacity, measured in kilowatt-hours (kWh). However, another important aspect of the Powerwall’s capacity is its Ah (ampere-hour) rating. In this section, we will delve into the world of Ah ratings, explaining what they mean and how they relate to the Tesla Powerwall.
What is Ah Rating?
Ah rating is a measure of a battery’s capacity to store electrical energy. It represents the total amount of charge a battery can supply over a given period. The Ah rating is calculated by multiplying the battery’s voltage (in volts) by its capacity (in ampere-hours). For example, a battery with a voltage of 12V and an Ah rating of 100Ah can supply 100 ampere-hours of charge at 12V.
How Does Ah Rating Relate to the Tesla Powerwall?
The Tesla Powerwall comes in two main models: the Powerwall 2 and the Powerwall+. The Powerwall 2 has a capacity of 13.5 kWh, while the Powerwall+ has a capacity of 9 kWh. However, the Ah rating of the Powerwall is not directly listed on the Tesla website. To determine the Ah rating of the Powerwall, we need to calculate it based on its capacity and voltage.
Calculating Ah Rating from Capacity and Voltage
The Powerwall 2 has a capacity of 13.5 kWh and a voltage of 400V. To calculate its Ah rating, we need to divide its capacity by its voltage. However, since the Powerwall’s voltage is not constant (it varies between 350-420V), we will use an average voltage of 385V for our calculation.
13.5 kWh (capacity) / 385V (average voltage) = 35.06 Ah
Therefore, the Ah rating of the Powerwall 2 is approximately 35.06 Ah.
