Power Conversion System( Bidirectional Inverter Performance )
Characteristics And Specifications


The power conversion system can control the charging and discharging process of the battery, conduct AC/DC conversion, and directly supply power to AC loads without power grid. PCS is composed of DC/AC bidirectional converter, control unit, etc. The PCS controller receives background control commands through communication, controls the converter to charge or discharge the battery according to the symbol and size of the power command, and realizes the regulation of the active power and reactive power of the grid. The PCS controller communicates with the BMS through the CAN interface to obtain the status information of the battery pack, which can realize the protetive charging and discharging of the battery and ensure the safe operation of the battery.

Charge and discharge system of PCS.jpg

                                                                      (Charge and discharge system of PSC)
The system consists of battery, PCS and grid, which is the most basic application scenario. It is often used for peak-load shifting. There are two operating modes, manual and automatic (setting charging and discharging time and power).

                                        Solar energy storage system(PV charging controller and PCS separated)

The PCS in this system, is built-in MPPT solar charging module, integrated EMS management system. It can realize that the solar panels provide power to the load preferentially through PCS, and the excess electricity is used to charge the battery. When the battery is fully charged, the electricity from the solar panels is fed into the grid through PCS.
·When the solar panel power is insufficient, the battery is discharged to supply power to the load.
·When the battery power is insufficient to support the load, the battery and the grid power supply the load at the same time. As the battery power varies from 100% to the battery under voltage protection value (can be set), the corresponding grid power supplies the load from 0% to 100%.
·The PCS has a load port. This port has the UPS function to meet the load uninterrupted power supply.

System Features

· Specially designed for smart grid and smart micragrid to accept power grid dispatching.
· Meet the requirements of lead acid battery, lithium battery, super capacitor, vanadium battery and other different forms of energy storage, and has a wide range of applications; Bidirectional inverter, constant power, current, voltage charge and discharge and other battery charge and discharge modes can be selected.
· With time period working mode setting function, set up reasonable working mode according to local power network

characteristics.   

· Two AC interfaces, i.e. mains interface and load interface, to realize grid connected operation and independent isolated grid operation.
· Perfect islanding detection and mode switching of parallel and off grid, when the power supply is suddenly cut off the PCS can automatically and seamlessly switch to the off grid working mode separate from the grid and establish a micro grid to operate independently.
· RS485, Ethernet, can bus and other communication interfaces are optional to realize remote monitoring.
·The smart grid master control system can be interconnected with on grid solar inverter,on grid wind power system, tidal power generation system, diesel generator and other energy modes to form a hybrid energy smart grid, which can realize a variety of networking modes.
