sonnenBatterie
Lithium Iron Phosphate (LiFePO4)
Energy Storage System

Do you want an energy storage system that lasts as long as your PV system?  The sonnenBatterie Energy Storage System has 27-28 years longevity!  Applications are for adding backup power to grid-tie systems - not for off-grid use. 

The sonnenBatterie Smart Energy Storage System uses Lithium-ion Iron Phosphate (LiFePO4) batteries, the longest-lasting and safest battery chemistry on the market which is superior to other battery chemistries –including Lithium-ion NMC (electric car batteries). With a long lifespan of 10 years / 10,000 cycles and a higher power output per kilowatt hour of storage, the LiFePo4 chemistry is ideal for stationary storage in addition to being more environmentally friendly. sonnen’s best-in-class technology is fully certified to UL standards making it the clear choice in smart energy storage.
