GE and Arista Partner on Renewable Energy

Arista designs and makes renewable energy systems and has partnered with GE to use their Durathon™Battery for their “Power on Demand” offering.

Power on Demand system uses renewable energy (wind, solar, …) and storage devices to keep that energy available for peak use.  Power on Demand can reduce energy costs by smoothing the demand for grid power and using stored power at peak times when energy charges are highest.

"“ … a custom-designed battery storage system and proprietary real-time demand monitoring technology. … releasing stored power only during peak demand periods, thereby reducing peak demand charges, … and lowering commercial electricity costs.”

GE’s Durathon Batteries are both smaller and lighter than traditional batteries, can last up to 20 years and are recyclable.

Compact wall-mounted electric vehicle charging

Charge your electric vehicle battery

GE charging station can be installed in the garage and quickly charge your electric vehicle to be ready for the next day’s commute.  The NEMA rating enables the device to be installed outdoors, if your situation requires.  …GE  wall-mounted electric vehicle charger is the Wattstation

…   “The GE WattStation Wall Mount delivers a full-cycle charge to a 24kWh battery in only 4-8 hours, whereas plugging an EV into a standard electrical outlet would require 12-18 hours to provide the same level of charge. 

Suitable for both indoor and outdoor installations, the GE WattStation Wall Mount is NEMA 3R rated to resist rain, sleet and even ice.

The unit measures only 24 inches tall, 16 inches wide and 6 inches deep.”   …
