I’d happily say that Tesla’s powerwall 2 is one of the best solar batteries on the market today. When you compare it to the powerwall 1, you can really begin to see how far the technology has come.
AC/DC Built-In Inverter
Having an AC inverter included makes the battery more available for all homeowners without the extra cost of installing a hybrid solar inverter. Not only this but its increased storage capacity of 13.5kWh mean that your home can be powered for longer. However, this doesn’t mean you can just connect the powerwall up to some solar panels, you will need an inverter to get this to work.
Did you also know that you can stack up powerwalls for extra capacity. Unlike most other batteries, you can link powerwalls together to combine a large storage space for your energy. Although costly, it’s a great way of overcoming a limited capacity if you have a large building or use a lot of power.
Liquid Cooling System
Additionally, a powerwall 2 comes with a liquid cooling system which sets itself apart from every battery on the market right now. This means it can perform in extreme conditions whether its -20 or +50 degreesC.
By using Lithium cells in their batteries, Tesla is offering some of the best batteries that are available in the world. The 2170 lithium battery in the powerwall 2 is similar to those that are in the Tesla cars.
Overall, a Tesla powerwall 2 is a really good solar battery in the day and age. However, I do think that solar batteries still have some improvements to make. One big one is the price, for homeowners it’s hard to justify spending so much on a solar battery. However, if the budget is there then a powerwall is possibly the best option on the market.
