Ampt in Canadian Solar installation

Ampt LLC, a specialist in power conversion technology, announced the deployment of its DC optimizers in a 33 MW solar photovoltaic (PV) system with Canadian Solar, Inc. one of the world's largest solar power companies. The project uses Ampt’s DC String Optimizers in one of the largest deployments of DC power optimizers in the world.

The 33 MW installation capped off a six-month evaluation period by Canadian Solar, which began with a smaller demonstration project. Following the successful demonstration, Canadian Solar selected Ampt’s String Optimizer as it consistently outperformed other designs while costing less.

When compared to other options, Ampt String Optimizers delivered superior value. Ampt’s patented technology puts voltage and current limits on the output of each optimizer to allow twice the number of PV modules per string and eliminate half of the combiner boxes and associated cable and labor. Ampt also performs maximum power point tracking (MPPT) on every 20 modules to mitigate losses due to mismatch, and allows the inverter to operate at a high and narrow input voltage range to improve inverter performance. Ampt’s optional string-level data reporting via wireless communication helped validate comparison data.

According to research from Global Market Insights, DC power optimizers will continue to see rapid growth in the solar market. While the use of DC optimization started with the residential market at the module level, Ampt’s String Optimizers bring unique power conversion technology to large commercial and utility-scale power plants by lowering the total upfront cost of systems while increasing energy generation.

Ampt delivers innovative power conversion technology and communications capabilities that improve the way PV systems are designed. The company, along with strategic partners in the HDPV Alliance, is lowering system cost, improving ROI, increasing energy generation and broadening the PV solar market.
