Alpha ESS

Alpha Energy Storage System

A new kind of power storage solution

AJ’s Electrical are proud to offer Alpha ESS (Energy Storage Systems) to Tauranga and the Bay of Plenty.

The combination of German design standards, Lithium Iron Phosphate battery chemistry, modular expansion and advanced electrical functions makes Alpha ESS a safe, reliable, cost-effective choice for solar energy storage and off-grid home electricity. Both the Alpha ESS Smile5 and Smile S6-HV can AC- and DC-couple to solar arrays or suitable power sources – including the national power grid.

The Alpha ESS units are also serious competitors of UPS’ (uninterruptible power supplies) if used without solar panels.

Alpha ESS Smile5

4.6 kW Hybrid Off-Grid System

The Alpha ESS Smile5 is all you need for a truly off-grid or combination off-grid/mains-connected home. Its high-tech ‘islanding’ function can keep your home’s essential circuits running without interruption in case of a grid power outage.

With the Smile5, it’s possible to directly connect a solar panel array (DC) at the same time as mains AC and solar invertor AC. This flexibility in connectivity makes it perfect for retrofitting to existing off-grid solar panel systems.

The Smile5 comes in a range of battery sizes. Depending on your off-grid energy storage needs, it is expandable up to 60.6 kWh.

  • Lithium Iron Phosphate (LiFePO4) cells are the safest among lithium battery types
  • Suitable for a new solar panel system or as a retrofit to an existing system
  • DC and AC compatibility
  • German-designed, high-performance and built to last
  • Many configurable operation modes
