If you are interested in energy storage, this announcement about LG Chem and SolaX Power collaborating seems potentially like a big one. LG Chem’s RESU6.4EX battery storage technology is being combined with a new hybrid inverter from SolaX Power and the system will be available worldwide in a few weeks. The SolaX inverter has been designed to work both on and off the grid. It also has an all-in-one charger in addition to the DC-to-AC inverter, and an energy management system. An animated illustration shows how the inverter works.
The LG Chem Li-ion RESU6.4EX battery has a storage capacity of 6.4 kWh, which can be expanded to 9.6 kWh or 12.8 kWh. It also has its own battery management system, and a free app which can be used to monitor its performance. There is a 10-year warranty and more spec information is here. Price information seems scant, but a UK website says it is £3,475, which is about $5,000. The LG Chem system has been designed to work well with solar power, as has the SolaX hybrid inverter. There are more details here.
“The partnership between SolaX Power and LG Chem highlights the significance of topics like renewable energies and their efficient use. It is also an indication of our market strength, and our high-performance product portfolio. We would like to take advantage of the opportunity with LG Chem, to further expand our business relationships with wholesalers and installers, especially within the European and Australian market,” said Michael Zhu, Global Sales Director at SolaX Power.
The LG Chem/SolaX Power energy storage system has been created to provide dependable grid protection, including during a power outage. So, what about the price? It wasn’t in the joint press release, so it isn’t clear, but one site lists some of the SolaX hybrid inverters between $1,300 and $2,100.
Based on these sources — which don’t appear to be perfect — one could guess the whole system’s price might be between $6,300 and $7,200.
It is fascinating to see these energy storage developments — especially following the announcement of the Tesla Powerwall — which seemed to anticipate, if not precipitate, some of them. Battery storage appears to be poised to be entering a new phase of greater visibility and usage.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
