System frequency modulation: the frequency modulation millisecond response of energy storage system
reduces the impact of load fluctuations on the power grid and improves the stability of the power grid.
Peak-load shifting: alleviate the contradiction of power consumption at peak, improve the utilization of
transmission and distribution lines, and ease the upgrading of power grid.
Reserve capacity: Ensure the safe and stable operation of the system in case of power failure.
DESAY energy storage products are widely used for the following:
Power generation side and grid side energy storage, industrial and commercial energy
storage, UPS communication base station stand-by power supply, household energy storage
and portable energy storage.
System frequency modulation: the frequency modulation millisecond response of energy storage system
reduces the impact of load fluctuations on the power grid and improves the stability of the power grid.
Peak-load shifting: alleviate the contradiction of power consumption at peak, improve the utilization of
transmission and distribution lines, and ease the upgrading of power grid.
Reserve capacity: Ensure the safe and stable operation of the system in case of power failure.
Peak-valley arbitrage: charge at low electricity prices, and generate power at high electricity prices to
achieve peak-valley spread arbitrage and reducing power utilization costs.
Off-grid operation: Photovoltaic, storage and charging integrated equipment ensures stable electricity
consumption, and is applied to automobile charging piles and users in remote areas.
Standby power supply: provide emergency power, and ensure stable power supply in case of power
failure.
Portable power supply: meet the off-grid electricity demands for emergency relief, medical rescue,
outdoor operations or outdoor travel.
Peak-valley arbitrage: charge at low electricity prices, and generate power at high electricity prices to
achieve peak-valley spread arbitrage and reducing power utilization costs.

Peak-valley shifting: Reduce the power consumption costs of enterprises or parks and save electricity fees for users by
storing energy in the valley period and supplying energy in peak demand response.
Demand response: If the short-term power consumption is higher than the transformer volume, the energy storage system
will discharge electricity quickly to satisfy load energy demands.
Standby power supply: When the power supply is suspended, it will offer uninterrupted power for important loads for a short
period of time, reducing the economic loss caused by the sudden power failure of the load.
Power transaction: Support short-term power trading on the power trading market based on load prediction to maximize
income.

Active safety is the core feature of our platform:
The platform utilizes intelligent monitoring and data
analysis, be able to identify potential risks of batteries
in advance and issue warnings.
EMS
Smart monitoring system
The company monitors the system status inreal
time through Wi-Fi or 4 G modules in order to
take pre-warning and preventive measures. The
system also supports localsystem information
preview, Web cloudaccess, and mobile appcloud
monitoring
Power Consumption Strategy
The system supports the configuration of
different kinds of power consumption strategies,
energy dispatching, and peakload shifting
viacloud in order to relieve power grid pressure
during peak hours, reduce the running costs of
the power grid, and enhance economic benefits.
Account Management
It also supports the management of different types of
accounts and authority distribution. The primary
account includes several kinds of management
accounts, such as distributor, operator, and user
accounts. Authorities include setting options and
options that canonly be viewed.
Automatic Settlement
The powerful background management statistics
support the statement statistics of each energy
storage system (industrial and commercial /
container energy storage systems). It also
supports various kinds of statistical models and
download functions.
