MN EnerStore 500

MN EnerStore 500

The MN EnerStore Zinc‐bromide flow batteries convert variable electricity to supply on-­demand electricity. Zinc-­bromide batteries have a higher energy density, are environmentally friendly, made from highly recyclable materials and completely recoverable at the end of their service life. They are modular and configurable to meet power requirements for a wide variety of grid interactive (on-­grid) and grid independent (off-­grid) market applications.
