The Powr2 POWRBANK is a portable power supply that integrates with diesel generators to optimize load capacities. Using advanced lithium ion battery technology and automatic load level sensing, the POWRBANK can switch power flow as needed between the generator and the POWRBANK. Pairing the unit with electricity-producing systems also enables the storage and use of alternative energy sources. Six POWRBANK models are available with outputs from 3.7 to 60 kilovolt amps. Storage ranges from 7.5 to 120 kilowatt hours. All models feature Powr2's Node Energy Control Module (ECM) 7-in. touch screen which retrieves data from all connected devices. The system displays the information on the screen and uses it to inform which energy source to use and which loads to prioritize.
