Generac’s generously proportioned home system
US residential back-up system provider Generac claims that the modules in its new battery energy storage devices offer the “highest storage capacity available on the market today”.
The company launched its new system PWRcell and its PWRview control and monitoring app in 2019, pitching both to the US industry at last September’s Solar Power International / Energy Storage International show.
At the beginning of this week, Generac said the products are now available to buy through the company’s installer network. It claims that users can realise “thousands of dollars of savings over the life of the product” through charging the battery with solar-generated or off-peak energy, in order to ride out peak demand times.
It comes with a 10-year limited warranty, also offers back-up power and is available in modular blocks from 8.6kWh up to 34.2kWh. The company claims that this outdoes the likes of Sonnenbatterie Eco, Tesla’s Powerwall and LG Chem RESU systems for modular capacity.
In related news, Generac acquired solar inverter manufacturer Pika in mid-2019.
EV player SERES spins out battery division
Automotive technology company SERES (SF Motors Inc), has completed the spin-out of its in-house Battery Technology Division into a new entity, TeraWatt Technology Inc.
Headquartered in Santa Clara, California, SERES currently produces two models of electric vehicle (EV) and has R&D centres in Japan and in Michigan; e-powertrain manufacturing and EV manufacturing sites at two separate locations in China; as well as a new product lab and an EV assembly plant in the US.
Established as a subsidiary in 2017, TeraWatt describes itself as a firm that engineers “ultra-high density lithium-ion batteries that work” and in August 2019 launched a 4.5Ah prototype solid-state battery design with a third-party validated energy density of 432Wh per kg, and expected to be available to “select early adopters in 2021 and full release in 2022”.
