Ampt announced the deployment of its string optimizer to power a 65 MW solar project located in the California Independent System Operator (CAISO) region. The photovoltaic power plant includes a DC coupled 25 MW/100 megawatt hour (4-hour) battery energy storage system and uses Ampt string optimizer to provide low-cost power at stable voltage to support the operation of critical facilities, including large artificial intelligence data centers.

The hybrid solar energy+energy storage system can achieve energy stability and transfer, ensuring the provision of renewable energy even in intermittent solar power generation. The system itself utilizes machine learning to evaluate the optimal timing and strategy for grid interaction. By signing power purchase agreements (PPAs) with multiple off takers, the power plant is expected to generate tens of millions of dollars in revenue for the local economy. In addition, it will also help advance California's goal of achieving 100% carbon free energy by 2045.

The Ampt string optimizer is an advanced DC/DC converter that can output all available photovoltaic power at a fixed voltage, helping to meet the strict power requirements of artificial intelligence data centers, as even millisecond level fluctuations can affect their performance during AI training. By stabilizing the voltage at the power generation point, Ampt can ensure stable power supply for the inverter and battery system, thereby providing stable and reliable electricity to the purchaser. In addition, the Ampt optimizer can reduce the inherent volatility losses of large-scale photovoltaic systems caused by factors such as cloud cover, pollution, and temperature changes, thereby maximizing solar energy output.

Mary Adam, Vice President of Global Sales at Ampt, stated, "By operating on the DC side, Ampt's technology can improve overall efficiency while reducing total system costs, making renewable energy a viable and flexible option for high-performance computing environments. We look forward to continuing to work side by side with our customers and partners to optimize their renewable energy power plants and support the infrastructure of these data centers
