1.Commercial Energy Storage Solution

● For companies, factories, commercial offices, charging stations and

other places that use large amounts of electric power and have large load

fluctuations or other places with large electric price differences between peak

and regular usage, the installation of an energy storage system will have a

major impact. The energy storage system can perform load shifting according

to high and low electricity pricing to stabilize the power grid and take advantage

of price differences; during power grid blackouts it can switch quickly to off-grid

power supply to implement emergency power supply to ensure important loads

continue to operate; as load requirements increase, the energy storage system

makes it easier scale the power supply system and to smooth out the load

impact thus saving of the investment costs of rewiring and transformer scaling

in applications such as electric vehicle charging stations or scaling old power

distribution systems, etc.

● Recommended products: PCS500K-A, PCS250K-A, PCS100K-A, etc.

● Applications: industrial companies, data centers, charging stations, etc.

● Solution features:

Load shifting: increases company profitability;

Emergency power supply: can be used to replace fire emergency

power supply (EPS) to save on system investment costs;

Smart monitoring: remote monitoring, highly automated operation.



2.Frequency and Voltage Modulation System

Solution

Large fluctuations in frequency and voltage in local power grids occur whensteel mills, glass factories, and other applications require large bursts of electricpower. This usually leads to an unstable power grid which affects the stability of other electrical equipment. In these situations, the addition of an energy storage system to the power grid can satisfy the requirement for quick response to sudden frequency and voltage changes and handle short term load power changes. Since the energy storage system only needs to handle power regulation for short periods of time, super capacitors or other power batteries can be used for short term energy storage.

Applications: primary power grid frequency and voltage modulationSolution features:Instant implementation of primary frequency modulation, secondary

frequency modulation can also be implemented;Effectively improves power grid frequency and amplitude stability;Fast dynamic response speed.

Recommended products: PCS500K-B, PCS1000K-B, etc.



3. Micro‐grid Energy Storage Solution● Micro-grid power distribution systems are formed from distributed power

sources, energy storage devices, energy conversion devices, related loads as

well as monitoring and protection devices. They are usually used in low and

medium voltage power distribution networks and involves many types of energy

devices to provide clean, efficient and stable electric power to loads.

● Solution features:

Ensures emergency power supply for various small ecosystems; isolated

island operation can also be implemented;

Highly permeable renewable energy can be introduced making it

environmentally friendly;

Customized photovoltaic, fuel power generation, and storage solutions

based on local conditions; better economic efficiency can be implemented;

High efficiency energy management; remote monitoring and highly

automated operation can be implemented.

● Recommended products: PCS500K-B, SPI500K-B, energy management

system



4.Wind and Solar Curtailment Solution

Since renewable energy generation is only possible at certain times andis volatile and unpredictable, its large-scale inclusion will introduce adjustment difficulties to power grids and large-scale wind and solar curtailment problems can also occur. The addition of energy storage solution to renewable energy generation solves this problem. By storing the unused energy and releasing it back during times of peak energy usage, the objective of smooth power delivery is achieved, and the problem of the instability in renewable energy generation is solved while waste is prevented.

Applications: locations with renewable energy generation limitations Solution features:

Reduces the effects of wind and solar curtailment, improveseconomic benefits;

Improves grid power generation stability and planning; Improves power grid scheduling.

Recommended products: PCS500K-B, PCS1000K-B, etc.
