UEC Electronic’s Ground Renewable Expeditionary Energy Network System (GREENS) saves fuel, money, and reduces the frequency of resupply missions. GREENS is the first viable solution to replace traditional fuel-fired generators. GREENS was developed as a USMC Program of Record but has applicability to both civilian and military customers. The system collects solar energy and converts it into useable power. Excess solar energy is stored in the array of high energy density battery systems (HEDBS) for use when solar energy is insufficient. The system is light-weight and man portable. The GREENS HEDBS is safe, and has been approved as UN/DOT Class 9 tested for commercial shipment.
———————————————————————————————————–
One GREENS will provide up to 1kW of power, and up to five systems can be paralleled together to provide 5 kW of power. No formal operator training is required. System deployment time is quick less than 15 Minutes by an untrained user. The system can be used as a completely renewable solution, or can be used in a hybrid configuration with a generator. If used as a hybrid solution, the GREENS controller will auto-start the generator if necessary to recharge the batteries, and will run the generator at peak efficiency.
When the sun is out we should all be taking advantage of it. Either through Solar electrical or solar heating. Up until now its been expensive or difficult to find a heater that takes advantage of the suns incredible heating power. Step by step video walks you through assembling this kit. All you need is a pair of scissors, a glue gun (and about 8-10 regular size glue sticks), a piece of 1 1/2 pipe at least 4 feet long and some flat black paint.
