Dynapower Company LLC, a Vermont-based leading supplier of power conversion systems, was selected by Panasonic Eco Solutions Canada to design and manufacture a 280 kW bi-directional energy storage inverter for use at the British Columbia Institute of Technology [BCIT] in Vancouver, Canada. The custom designed inverter will have five (5) independently controllable DC inputs; four (4) battery inputs and one (1) input with Maximum Power Point Tracking (MPPT) for the integration of solar.
“We chose Dynapower because of their significant experience in producing unique solutions for unique requirements,” said Goki Otowa of Panasonic. “Dynapower’s engineered solutions and professional support has helped us navigate through the complex requirements from the customer and define the path to success.”
At the BCIT campus the loads will be two electric vehicle chargers with possible future expansion to include critical support infrastructure for the university. The system will permit electric vehicles to be charged from solar generated power, and when solar power is being produced but no cars are being charged the solar energy will be stored in batteries for use when solar generation is not possible, such as at night or on cloudy days.
“Providing a highly engineered solution to Panasonic a global leader in electronics is technically demanding and a recognition of Dynapower’s expertise in energy storage” said Adam Knudsen, President of Dynapower. “We look forward to expanding our partnership with Panasonic as we continue to design and manufacture power electronics for energy storage systems.”
The inverter is equipped with Dynapower’s proprietary Dynamic Transfer algorithm permitting bump-less transfer from grid tied mode to stand-alone [microgrid] mode without any affect to the connected loads. The inverter has 5 DC inputs, 4 battery inputs each rated at 70 kW and 1 solar input rated at 250 kW. The level of efficiency achieved with a 5 DC input energy storage system is unparalleled and opens up significant new market opportunities. The inverter will be tested to UL 1741, IEEE 1547 and IEEE 519 standards and certified for compliance. The system installation will begin in September and full commissioning is scheduled for October.
