BATTERY BACKUP FOR HOME UK UPDATE

Increased Power output via software updateĮarlier in 2021, Tesla announced a new software update that can increase the continuous and peak power rating by up to 50% on some later model Powerwalls. Heat and batteries just don't go well together.

The IP rating (weather rating) remains high at IP56, although it still should be installed in a sheltered location, such as a carport or garage, and out of direct sunlight if possible. Still weighing in at 120kg, it is definitely not light, although thankfully, it can now be ground-mounted as well as wall-mounted. Interestingly it also has a simple on/off switch on one side. Gone are the sleek curves of the first Powerwall, giving way to a more practical rectangular shape with venting on either side for cooling and a bright green LED strip. The larger cells have several advantages, including a greater energy density and a longer runtime.Ĭompared to the first Powerwall, the Powerwall 2 was designed to be more compact, easier to handle and simpler to install. The original Powerwall 1 used the smaller 18650 size cells, while the Powerwall 2, reviewed here, uses the larger 21-70 cells, which have a 21mm diameter and are 70mm long. The Powerwall uses lithium NMC (Nickel-Manganese-Cobalt) battery cells developed in collaboration with Panasonic, which are similar to the Lithium NCA cells used in the Tesla electric vehicles. Price drop! After years of consecutive price rises, 2023 has seen two reductions taking the price down to just under $13,000 dollars in Australia (excluding installation), a total drop of $3,330 in just 4 months. However, it is now one of the more expensive on the market. When first released, the Powerwall was one of the most affordable AC-coupled battery systems. Likewise, the price increased substantially in the US to over $11,000. The first modest increase of $950 was announced in March, the second in May, and the largest and most recent price hike was in October, lifting the cost of a Powerwall system above $16,000 Australian dollars. During 2021, there were several price fluctuations, but in 2022 the price shot up dramatically with three consecutive price increases. Surprisingly, another two price increases occurred during 2020, lifting the price to around AU$11,000. The Powerwall had its first price increase in late 2018, bringing it up to AU$10,000 (US$7400).
