Overview

The Pfhotonika system consists of a fully integrated, off-grid renewable energy storage and delivery system. The initial system for military applications is comprised of two (2) trailers one containing a fold-out 5kW/50kW /100kW solar array and the second an energy storage system and control module.

Excess solar power is converted into high pressure (350-2000 psi) hydrogen stored in lightweight carbon fiber tanks. The stored hydrogen is used to supply 5kW/50kW/100kW fuel cells for distributed power generation.

A connection to diesel generators is provided to utilize their wasted generation capacity for later use via the fuel cell when generator sets are operating on partial load or standby modes. A programmable controller with a hardened wireless tablet manages all of the various hybrid power distribution schemes to best make use of all energy.
