![]() Installation costs are generally about $4,000. This brings the total cost, including installation, to $14,600-$16,850. EnergySage lists the pre-install cost of the Powerwall at $10,600 to $12,850. A Powerwall's dimensions are 45.3 in × 29.6 in × 5.75 in.Īs mentioned previously, Tesla no longer offers the Powerwall as a stand-alone purchase-it must be added to a Tesla Solar order. Powerwalls are stackable, and you can have 10 stacked in total. In April 2021, Tesla CEO Elon Musk announced that the Powerwall is now bundled with other Tesla solar products, meaning that Tesla solar panels and the Powerwall cannot be purchased independently. Installers are widely installing the Powerwall+, which integrates a solar string inverter and system controller, though the original Powerwall (also called Powerwall 2) is still available in some cases. Enphase allows you to add a maximum of 4 IQ 10 battery units per installation. These batteries are also modular, so multiple units can be used together to increase your home's storage. This means that you won’t be able to pair an Enphase battery with a pre-existing inverter system unless it is an Enphase system. It is important to note that the Enphase IQ is only compatible with the M and IQ series Enphase microinverters. When it comes to energy storage, Enphase offers two IQ battery sizes: For the past 10 years, the company has been the market leader in microinverter technology. Round-Trip Efficiency (RTE): how much energy your battery can provide your household compared to how much you can storeĭepth of Discharge (DoD): the percentage of a battery's energy that has been discharged relative to the overall capacity of the batteryĮnphase is known for its reliable solar equipment. While a larger pipe allows more water to flow through, it also depletes the water source more quickly, so various levels of battery power and capacity can work well depending on your appliances and energy needs.Ĭycle: when a battery has been drained and recharged ![]() The energy capacity is like the amount of water that will push through the pipe, and battery power is like the size of the pipe itself. To help you visualize power and capacity, let’s compare a battery to a water pipe. ![]() Batteries with a higher power rating are capable of powering heavy-duty appliances or many appliances at once, while high-capacity batteries can store more total energy and run your appliances for longer periods of time without needing to recharge.Power: the amount of energy that can be pulled from the battery (high power ratings can supply more energy but burn through the storage capacity faster) We will start by going over the basics of both the IQ Battery and the Powerwall, and then we’ll evaluate the products based on pricing, efficiency, depth of discharge, battery type, warranties, and monitoring.Įnergy/storage capacity: the amount of electricity a battery can store In this article, we will compare the Tesla Powerwall and Enphase IQ batteries so you can make informed decisions if you are interested in energy storage. Outside of its popularity, however, is the Powerwall really "all that"? While it has several impressive features, it is important to compare its capabilities with those of other leading energy storage options. Tesla's energy storage device, the Powerwall, has been so popular that Tesla has had to implement waitlists and adjust their supply to meet the public's high demand. Their electric vehicles and other, more recent developments (specifically, their CEO's activities) frequently find their way to headlines and day-to-day conversations. If you're tired of dealing with power outages or if you feel like expensive peak grid electricity prices are eating away at your wallet, you might benefit from solar energy storage.Įven if you're someone who is new to solar technology, you've likely heard of Tesla.
