Delta Introduces 480 VAC/125kW Power Conditioning System At Solar Power International

Delta has introduced its latest Power Conditioning System (PCS) at Solar Power International. The PCS is designed to convert power between static energy storage and the grid with top-of-the-line efficiency said the company in a statement.

Delta’s PCS is a bi-directional conversion system that offers both energy management and power quality management capabilities.

According to the company Delta 480 VAC/125kW PCS enhances the value of energy storage and ensure interconnectivity and quality power between renewable sources, energy storage technologies, the power grid, and consumers.

Serving as the cornerstone of the company’s new line of energy products, the bi-directional system works by converting AC power from the grid and photovoltaic inverters to DC power for static energy storage applications.

The PCS converts the stored energy back to AC power for seamless use by end users. With an impressive high-efficiency peak of 97.8 percent and a California Energy Commission (CEC) efficiency of 97.6 percent, Delta’s PCS ensures that consumers are getting the most out of their renewable resources and grid energy purchases. The solution, which is scalable up to 500 kW in parallel configuration, is designed for easy installation with straightforward wiring and integrated AC/DC switches. The Delta PCS solution also includes energy management and power quality management add-on features.

For commercial and industrial structures, the Energy Management application has a Peak Shaving Mode that allows for increased control over energy consumption and demand charges, such as fees based on a customer’s peak utility energy usage during a billing cycle, typically measured as a 15-minute interval. In this mode, when peak power consumption exceeds average value, the system will dispatch stored energy to reduce the amount of energy purchased from the grid, thus lowering utility costs.

For power providers, the Grid Power Quality Management application can compensate for poor grid voltage and frequency by providing both reactive and active power.

The company is also showcasing its comprehensive line of 3-phase photovoltaic (80/60/42/32/28/24 kW) inverters, which convert direct current (DC) output from a photovoltaic system into a utility frequency alternating current (AC) output, for residential, commercial and industrial applications.

“Making the most out of the renewable energy we currently have on hand is key to reducing our reliance on fossil fuels and creating a more sustainable future,” said M.S. Huang, President of Delta Americas. “With our new Power Conditioning System and line of PV Inverters, which feature high-end efficiency ratings, we’re enabling homes, businesses and utilities to optimize their energy usage within the built environment. These products create value not only for our customers, but for society as a whole.”
