Is Tesla Powerwall Battery Just a Toy or Much More?

Tesla has a new and exciting product – the Powerwall 2 storage battery. This new, or rather, updated product is much more powerful than its predecessor, and it even comes with an integrated inverter. This is a massive and significant upgrade.

Why is this good news? Well, because of you. Tesla’s new battery sets a new standard for other companies, and a competitive market means lower prices for you. But the more important question is this one – Why would you even want a battery for your house? The answer is surprisingly simple. If you want to save money, you can do it by investing it in a house battery.

The Powercell 2.0 will let you get power from your electricity provider at night when the rates are lower and then use it during the day. Additionally, if you have solar panels, it will let you be more power independent.

The thing is, these batteries are not cheap. They’re pricey, but for a good reason. Each unit costs $5,500, and your home will probably need at least two or three of them. If you opt for buying just a single unit, then you should use it just to power critical appliances in case of an outage.

Tesla Powerwall 2.0 can store 13.5 kWh of energy and provide 5 kWh of continuous power, and when we compare it to its competitors such as LG Chem RESU and sonnenBatterie eco compact, it’s obvious that Tesla has a significant advantage. Let’s take a look at the differences:

sonnenBatterie eco compact

Energy capacity: 4 kWh

Cost: $5,950

Cost per kWh: $1,488

Inverter: Included

LG Chem RESU

Energy capacity: 6.5 kWh

Cost: $4,000

Cost per kWh: $924

Inverter: Not included but can be bought for $2000

Tesla Powerwall 2.0

Energy capacity: 14 kWh

Cost: $5,500

Cost per kWh: $393

Inverter: Included

As we can see, Tesla Powerwall 2.0 is head and shoulders above its direct competitors. It’s now obvious that Elon Musk was not exaggerating when he said that this new product will be exciting.

Are there any downsides?

The Powerwall’s battery technology is quite similar to other rechargeable batteries of all sizes. That means that Tesla’s battery will eventually lose some of its ability to hold charge, but that was to be expected.

Tesla’s battery life will also deteriorate over time. That’s not an indicator of a flaw in design, that’s just unavoidable when it comes to batteries. All batteries lose their abilities over time. The good news is – Tesla Powerwall 2.0 comes with an unlimited 10-year guarantee. The warranty is one of the most important criteria because it can tell you how much faith a company has put into its product, and you can tell whether buying that product is a wise investment.

The installation of Tesla’s battery costs around $1,000, and it’s always done by certified professionals.

What’s in the batteries?

Tesla batteries use nickel manganese cobalt (NMC) battery chemistry, which is perfectly safe – until you puncture it. Don’t be afraid because NMC batteries are perfectly safe, but if they’re improperly charged or damaged, there’s definitely a modest risk of fire. That’s nothing to panic about since the chances of that happening are minimal, at least if you take good care of your battery.

Is it a toy?

As you can see, the answer is quite obvious ‒ NO. Tesla’s battery is one of a kind for now, and it offers much more than similar types of batteries. It’s hard to justify buying any other home battery than Powerwall. It offers much more capacity than its competitors, and you can obviously get twice the energy capacity for the same amount of money.
