Advanced Lithium Iron Phosphate Batteries

Manufacturing photovoltaic panels in Hawaii might seem like a risky proposition given the competition from low-cost producers on the mainland and in Asia and Europe.

But Honolulu-based Greenpath Technologies Inc. is giving it a shot, producing a niche product at its facility in Kakaako that combines lightweight folding solar modules and a battery storage system that can provide power in remote areas.

The company got a good response when it demonstrated its “Solar Transportable Alternative Energy Storage System” earlier this year at military and disaster relief exercises in the Philippines and Thailand, said Jim Chaney, Greenpath’s director of product development.

The energy storage part of the system features lithium iron phosphate batteries that have a longer life and charging times that are 10 times faster than other batteries used in military applications, he said. The brain of the system is a charge controller/inverter that converts the solar energy to usable voltage for lighting, electric motors and other devices.

Product Development: Embracing product safety and compliance

PRODUCT DEVELOPMENT: EMBRACING PRODUCT SAFETY AND COMPLIANCE Recent safety incidents on storage plants have raised concerns about the fire safety of battery storage systems. Such events are extremely rare compared to the cumulated global deployments of energy storage systems, which have reached more than 27 GWh by end of 2020 (Wood Mackenzie 2021). However, for…
