FORT COLLINS -- Ampt LLC reports rapid adoption of the company’s String Optimizer products in large-scale PV solar+storage projects totaling one gigawatt-hour (GWh).
Ampt String Optimizers are DC/DC converters that deliver higher performing solar+storage systems that cost less than solutions without Ampt, the company said.
Ampt said it attributes the recent series of projects to the adaptive technology in its String Optimizers that delivers value in a wide range of system sizes and storage applications.
These projects combine solar PV with DC-coupled energy storage. The mix of projects include several PV systems ranging from 50 to 100 megawatts (MW), multiple projects between 10 and 30MW, and numerous 10MW and under projects.
The PV-to-battery-to-inverter ratio on these systems range up to 2:1:1 with two- to five-hour charge durations being most common.
Project locations in the U.S. include California, Hawaii, Massachusetts, New Jersey, and New York.
In January, Ampt String Optimizers were deployed on a record-breaking PV peaker power plant that has 28MW of solar PV and 100 megawatt-hours (MWh) of DC-coupled energy storage.
"These projects are a testament to the industry's recognition of the value that both Ampt optimizers and DC-coupled energy storage bring to solar," said Darryl Parker, Ampt VP of sales and marketing.
Including energy storage allows PV systems to provide energy on demand and supports grid stability. DC-coupled energy storage systems charge batteries directly from the DC solar array to achieve a lower cost per megawatt-hour compared to AC-coupled approaches.
"Innovations in energy storage are driving its rapid growth in large-scale PV systems around the world and Ampt's technology is an example of what can be done to improve economics," said Levent Gun, Ampt CEO.
"We look forward to continuing to build strong relationships with our partners and customers to increase global renewable energy capacity."
