Solar Energy: Tesla Powerwall: What you need to know
Tesla characterizes the Powerwall as a ” rechargeable lithium-ion battery with liquid thermal control. ” This is one of the few residential energy storage companies that produce small scale batteries for energy storage at home. The Powerwall’s first generation was introduced in April 2015 and then in October 2016 an upgraded Powerwall 2.0 was announced. The unit price of a Powerwall 2.0 battery (not including installation costs) was $ 5,500 before April 2018. But since then, this has increased to $6,700.
The electrical interface of Powerwall offers a simple connection to any home or building. Tesla’s Powerwall is Australia ‘s most popular battery storage system. The Powerwall is compact and contemporary and can be easily and quickly mounted inside and outside on your floor or walls.
Tesla battery packs are an ideal match for solar panel systems, especially in off-grid projects where homeowners need to become totally independent of their utility. A solar storage solution such as the Tesla Powerwall enables you to continue to maintain a continuous power supply in the day or night.
How does the battery pack of Tesla measure against all other energy storage options available at home? Continue reading to more about the Tesla Powerwall.
An AC coupled energy storage solution will take AC electricity either from your standard grid connecting solar inverter or from the grid itself, transform it to DC electricity which can be stored in the battery and then transform it back to AC electricity, once excess energy is needed. The main difference between this kind of solution and the previous Powerwall model is that this unit has its own battery inverter and system for battery management.
The Powerwall works differently based on the mode it’s in. The most common mode is labelled, home self-powering. This simply means that whenever the solar system in the house generates even more energy than the electrical appliances in the house, the Powerwall will take the excess power and store this in the battery until the battery is fully charged. When the electrical demands of the house exceed what the solar panels produce at that moment, the power wall releases the energy in the battery to power the electrical charges until the battery is completely discharged.
PowerWall 2 can store 14 kWh of energy (kilowatt hours). Based on the average US home consumption of around 28 kWh a day, it is quite a substantial amount of storage to handle a lot of the electricity use of a typical house during the night.
