Delta was founded in 1971 and has been the global leader in switching power supply solutions since 2002 and

DC brushless fans since 2006. Delta offers some of the most energy efficient power products in the industry,

including switching power supplies with efficient over 90%, telecom power with up to 98%, and PV inverters with

up to 98.8% efficient. We have also developed the world's first server power supply certified as 80 Plus Titanium

with over 96% efficient. We regularly invest around 8% of our annual sales revenues in R&D and have worldwide

R&D facilities in Taiwan,China, Europe, India, Japan, Singapore,Thailand, and the U.S.

Delta’s power conditioning systems (PCSs) are built on the basis of years of experience in power

electronics and energy control technology. The compactness of these systems saves space while offering

scalability for various system configurations, as well as battery technology independence and integrability

with battery systems from mainstream brands.

This means they can enable customers to build up energy storage systems (ESSs) that meet the

requirements of grid-tied/off-grid, utility-scale, and behind-the-meter applications to improve energy

efficiency and operational profitability.

Advanced Control for

Energy Storage Applications

Delta’s advanced control systems enable their PCSs to precisely manage battery energy storage and discharge

in line with the needs of different energy storage applications under minimum risk.

Optimizing Surplus Renewables

PV Self-Consumption

RE100 Commitment

Store excess solar power to boost the usage of locally

produced power.

Eliminate the gap between purchased renewable energy

supply and actual demand to help realize RE100.

Managing Fluctuation

Frequency Regulation

PV Smoothing

Real-time detection of grid frequency and

implementation of charging and discharging to

maintain frequency stability.

Eliminate fluctuations in solar power generation and

allow power to be connected to the grid steadily.

Matching Supply and demand

Energy / Load Shifting

Charge batteries during off-peak periods and

discharge to supply power during peak periods on

the basis of ToU or generator scheduling.

Peak Shaving

Discharge power when the consumption exceeds

upper limits to flatten peaks in electricity demand.

Ensuring Self-Reliance

Backup for Power Generators

Backup Power Supply for Commercial & Industrial

Replenish power in a timely manner to prevent underfrequency load shedding and large-scale power

outages during grid failures.

Provide energy for critical systems when the grid fails, thus

avoiding costly downtime and pollution from diesel engines.

DC-Coupling

Solar-Plus-Storage

• Storing excess solar power in the day time and

keep earning during the night time.

• Curtail initial investment on equipment and

installation.

• String-level DC/DC converters with independent

MPPT that can increase solar energy generation.

• Runs as a microgrid system that can seamlessly

switch between grid-tied and off-grid modes.

Optimizing CAPEX of PV systems paired with energy storage system by leveraging a PCS (DC/AC converter) and

avoiding the installation of a dedicated MV transformer.

Solid Oxide Fuel Cell (SOFC) Systems

• Grid-tied solution for low-voltage batteries.

• Triple-hybrid microgrid systems with multiple

energy sources.
