Samsung SDI introduces 5.5 kWh and 8.0 kWh residential energy storage units

Samsung SDI unveiled two residential energy storage systems (ESS) at Intersolar Europe 2015 in Munich, Germany. The new 5.5kWh and 8.0kWh units join the existing 3.6kWh system.

The new residential EES integrates the PV inverter, battery PCS and Li-ion battery. As a DC system, the Samsung All-in-One system is highly efficient in storing solar energy into electrical energy because PV generation in form of DC is stored in battery without DC/AC inverting.

The battery in the All-in-One is the same battery used in German premium EV cars and grid-scale energy storage system in Schwerin, Germany. Samsung SDI says that it is the only Li-ion battery company without a single recall. Samsung SDI assures long- term product warranty for 5 years, with a performance guarantee of 10 years.




I'd say the Tesla batteries is much sexier.


They already had a 5.8kwh system, the specs are quite interesting:

Pretty good for LMO, 80% DOD, 4,000 cycles to 80% capacity.

The 8kwh unit will offer a good comparison to the Tesla Powerwall 7kwh.


Both LG and Samsung may compete favorably (with regards to looks, quality, performance and price) with Tesla/Panasonic, Sony, Toshiba and European manufacturers for ESS units.

The two large Korean manufacturers can afford to quickly upgrade and mass produce their ESSs in all major world markets.


Calgarygary....screw the battery, I'll take the sexy model draped over it like it was a hot rod magazine LOL


This market is clearly something that has been waiting to happen because they've all been eyeing it and some were already dipping their toe in the water. But with Tesla's announcement, it's now high profile.

Will be interesting to see if it takes off or they need another generation of batteries to bring the cost down and make it truly affordable. And "generation" in battery terms means about 3-5 years. Just how I'm using the term here.


If the picture makes you want to screw the battery, you are worryingly confused....

No price per kwh. Reason. They can't compete with Tesla's products. Tesla's announcement was not big news because they showed a grid battery (apparently lots of other producers offer that. The big news for the battery storage industry is Tesla's price level which is about 60% below the market price currently.

Apart from price Tesla's product scales from small to incredibly large. Samsung does not. Tesla's powerwalls are sexy even without a pretty young woman. They are more compact and less heavy. Half of Samsungs. Tesla's product is also more flexible. If you at a later point in time decide to double your solar panel installation from say 6kw to a 12kw installation you can also double the number of supporting powerwalls and replace the separate inverter with a larger one. This is not an option with Samsung's system that is locked into one size.


Koreans have adapted to the automobile/ship/electronic markets (etc) with great successes and they will do so with future competitive ESS and EV batteries market.

TESLA/Panasonic will have many powerful competitors from Asia and Europe before 2020 or so, as did the Big Three with the results we all know.

Let us not forget that 60+% of the ESS, EV batteries, BEVs, solar systems, wind turbines and other energy units market will soon come from ASIA. Most of the manufacturing will be done locally to reduce transportation and manufacturing cost.

The King of the road has moved.
