630 KW Power Conversion System Outdoor Cabinet For Energy Storage / Micro Grid System

Siny-bank series of outdoor cabinet energy storage products are composed of centralized PCS integrated power control cabinet and high energy density lithium battery system cabinet into highly integrated energy storage products, which can realize the configuration of various power and capacity conveniently and flexibly, and can also realize the parallel networking of multiple devices to form medium and large energy storage systems. With flexible layout, convenient installation, convenient maintenance, and safe isolation, compatible with the application of user-side and power-generation side energy storage. PCS integrated power control cabinet mainly includes modular PCS, AC and DC power distribution system, monitoring system, PMS and protection system.

• Product features
• Charge and discharge management

• With battery charge and discharge management function, support constant voltage, constant current, constant power charge and discharge and 24-hour different time period charge and discharge power Settings, and can be updated through the remote cloud platform. When the maximum value of the battery string reaches the limit value, the energy storage converter automatically adjusts the battery string voltage within the limit value. The energy storage converter can take necessary current limiting measures according to the instructions of BMS or EMS to avoid damage to the battery and itself caused by charging and discharging current.

• Communication and monitoring

• The battery energy storage system can connect to monitoring devices such as RS-485, LAN, and EMS. Equipped with 4G communication module, through the cloud control system can realize the system software remote upgrade, remote start and stop functions, can support mobile phone small programs. Through the mobile phone small program, you can clearly display the real-time operation data and curves, real-time fault information, historical fault information.

• Power control

• Active power control and reactive power regulation can be realized according to the control system instructions. The energy storage converter can adjust the active power according to the command of the control system to ensure that its maximum output power and power change rate do not exceed the given value.

• Security and protection

• Integrated power control system is equipped with hardware fault protection and software protection at the same time, the protection function is perfect, to ensure the safety of the system in various failure situations.

  Provides the following protection functions:

  1) AC incoming line phase sequence error protection;

  2) Protection of power grid voltage imbalance degree;

  3) AC and DC overcurrent/short circuit protection;

  4) AC and DC over/under voltage protection;

  5) AC over/under frequency protection;

  6) DC polarity reverse connection protection;

  7) Heat dissipation system fault protection;

  8) over temperature protection;

  9) Battery overcharge and overdischarge protection;

  10) Communication fault protection.
