    A complete buyers guide to Tesla Powerwall 2

    The Tesla Powerwall 2 is a home solar battery storage system introduced by Elon Musk's electric vehicle company, Tesla, in 2015. With the help of this innovative device, households can save energy, thereby saving money and have backup power in case of emergencies. Tesla Australia is dedicated to bringing the newest Powerwall models closer to home energy solutions. Discover the main characteristics and advantages of owning a Tesla Powerwall with this guide.

    What is the Tesla Powerwall 2 price?

    A home battery system such as the Tesla Powerwall 2 allows you to store energy from your solar panels for later usage. A Powerwall 2 installation in Australia usually costs between $13,000 and $15,000. This cost covers delivery, the Gateway device, the battery itself, and expert installation by a licensed electrician. The Tesla battery Powerwall 2 is a really good deal. With a 13.5 kWh storage capacity, it's among the most affordable choices out there. Over time, the cost has varied. It arrived in 2017 at a reduced price of about $9,000. However, in 2022 the price rose to $16,500 as a result of high production costs and demand. Thankfully, Tesla started to cut the price in early 2023. Currently, the base tesla powerwall 2 battery price (excluding installation and Gateway) sits around $10,400 after including a Tesla rebate.

    Components of Tesla Powerwall 2 and its backup gateway

    Consider a battery as a container with two sides: the cathode, or positive side, and the anode, or negative side. An electrolyte is a particular solution that is used to separate them. The electricity flows due to this simple configuration. The technology used by the Tesla Powerwall 2 is lithium-ion. Here, a mixture of lithium, cobalt, nickel, and manganese (LiNiMnCoO2) makes up the positive side. Although the Tesla solar battery uses lithium-ion batteries, there are other battery options for residential energy storage, including lithium cobalt oxide (LiCoO2) and lithium iron phosphate (LiFePO4). The Powerwall 2 boasts a 10-year warranty and delivers a powerful 5kW output, ideal for larger homes. Need even more power? Multiple units can be easily connected for commercial applications. The Powerwall 2 is remarkably small, measuring only 1.15 by 0.76 meters. This makes it easy to place on a wall, indoors or out, according to what you want. Now, let us talk about the battery’s backup gateway. Consider a blackout. Your house is quiet, the appliances are silent. However, what if the lights were powered by your Powerwall battery and solar panels? The Tesla Gateway fills that need. Consider the Gateway to be the central nervous system of your backup power supply. It lets your Powerwall reach its full potential and take over smoothly in the event of an outage. In the event of a power outage, your solar and battery system would be inactive if the Gateway is not present. The primary advantage lies in the Gateway's ability to maintain your home's power isolation from the grid in the event of an outage. By halting the flow of energy back into the wires, this essential safety precaution safeguards utility personnel who are replacing power. Although this feature is integrated into some battery systems, the Tesla Gateway provides an alternative. It's crucial to account for this additional expense (about $1,700) when estimating the total cost of your solar and storage purchase.
