About Sustainable Energy

Sustainable Energy ( designs and manufactures advanced
power electronics for distributed smart grid and micro-grid applications.
Advanced power electronics are a critical interface between all distributed
generation and storage systems devices, ensuring the delivery of high quality
alternating current (AC) to the power grid as well as providing utility control
over the interconnection and power quality.

Sustainable Energy's bi-directional low voltage energy storage inverter directly
connects low voltage batteries to the grid with the power industry's highest
round trip (battery charging and discharging) efficiencies. The inverter meets
tough utility smart grid standards such as Germany's VDE 4105 which is becoming
a global standard and enables full utility control over the battery dispatch and
power quality functions.

The inverter's software configurable platform has been designed from the ground
up to be easily integrated into power management systems, with the industry's
only open industry standard communications software to support a highly cost
competitive OEM strategy and allowing rapid development of OEM partner product

Sustainable Energy's platform is based on patented breakthroughs in power
inverter design that enable its platform to convert high current/low voltage DC
into high quality AC with conversion efficiencies that are materially higher
than anything in the market with an inherently lower cost structure.
