Tesla Powerwall 2.0
Australian RenewEconomy evaluated 30 different home energy storage systems and found out that Tesla's offer on its latest energy storage system is the best of the best.
The new Tesla Powerwall 2.0 not only beats competitors, but second best model is 30% behind Tesla on price per warranted kWh under 1 cycle per day utilization.
Tesla Powerwall 2.0 (unveiling story) is 14 kWh ESS (13.5 kWh usable) with 10 years warranty, with built-in inverter (AC version) or DC converter (DC version). Up to 9 units can be installed in one system.
Tesla Powerwall 2.0 Specs (updated)
Having built-in inverter makes Powerwall 2.0 even more attractive compared to other ESS.
"The SolarQuotes Battery Comparison table gives the cost per warrantied kilowatt-hour for over 30 battery systems when fully cycled once per day. The results are shown in the graph below, and as you can see, both versions of the Powerwall 2 are well ahead of the closest competition.
The Powerwall 2 is almost 30% cheaper than its next closest competitor, but the comparison is actually better than the graph makes it appear because the AC version of the Powerwall 2 includes a built in battery-inverter and the DC version includes a built in DC converter while its closest competitors on cost per stored kilowatt-hour do not.
This means the AC Powerwall 2 could installed without any additional hardware while the next 4 battery systems on the graph would require a separate battery-inverter to be installed the same way."
