Ampt, the DC optimiser company for large-scale photovoltaic (PV) systems, has announced the deployment of its string optimisers to power a 65MW solar projected in the California Independent System Operator (CAISO) region.
The company said its string optimisers, which are DC/DC converters, can be used to deliver power at a stable voltage to support critical facilities including AI data centres.
The PV power plant it has been deployed in includes a DC-coupled 25MW/100MWh four-hour battery energy storage system (BESS).
The hybrid solar and storage system solution is claimed to enable energy firming and shifting to ensure renewable power availability as solar generation can be intermittent.
This includes being affected by factors such as cloud cover, soiling and changes in temperature that can all cause losses.
It uses machine learning to assess optimal timing and strategies for grid interaction.
The string optimisers are said to enable the full available PV power to be delivered at a fixed voltage so that power requirements of AI data centres can be met.
It stabilises voltage at the point of generation, which the company said ensures a steady supply to both the inverter and BESS for reliable power to offtakers.
Mary Adam, vice president of global sales, Ampt, said, “By operating on the DC side, Ampt’s technology enhances overall efficiency while lowering total system costs to make renewable energy a viable and resilient option for high-performance computing environments. We look forward to continuing to work side-by-side with our customers and partners to optimise their renewable power plants and infrastructure supporting these data centres.”
