Where is Samsung in home ESS device "All in One" of USA market?

LG Chem., Samsung SDI, Tesla-Panasonic and BYD is four major manutacturer of Li-Ion battery in the world

Tesla(powerwall), LG(Resu) and BYD(B-Box) is release home ESS device already 

but can't find Samsung (all in one) in market specially USA

USA is the largest home ESS market in the world

Samsung SDI has “all in one” brand home ESS already that is similar type of Powerwall2 included PCS device in battery system

and many time participate to exhibition in world wide but can't find it in USA market

Samsung SDI still focus on battery for his cellular phone, electric car and large or medium size ESS, maybe small size home ESS device is very little position in his current business plan

 

but home ESS device is very sharply expand in USA, Japan, Australia and Europe(specially Germany) because this country is very enpansive cost of electricity and high percentage of solar and wind power in their power grid

therefore their government has incentive system for home ESS

this means home ESS market of this countrys will be expand more sharply in the further

Also many other new competitor like as BMW, Benz & Nissan release home ESS device in USA market

if Samsung will delay release more his home ESS, may be at a disadvantage in the home ESS in USA market
