The bidirectional converter can achieve the electrical conversion between DC and AC. It can convert AC into DC to charge the battery and convert DC into AC to power loads or back feed the grid. The power conversion system features advanced digital control technology that helps to enhance a stable operation of the PCS system. It can switch among grid-connected discharging, grid-connected charging and off-grid operation modes. The power conversion system has a wide range of DC currency input; therefore it can meet the charging and discharging needs of different battery combinations. The PCS system is characterized by modular design in terms of structure and power, which allows flexible battery pack connections for the same power output. All of these designs greatly prolong the service life of batteries.

Configuration

AC/DC Converter Module

Bidirectional AC / DC converter can convert DC into AC and AC into DC. In addition, it can convert AC to DC to charge battery, and convert DC to AC to provide power to loads or back feed grids.

Static Transfer Switch

Automatic static transfer switch could be shifted within 10ms. Under normal operating conditions, the static switch is on. When mains power fails, the static switch would turn off immediately and the battery system thus shifts to off-grid modes to power loads.

Monitoring System

The power conversion system monitors the status of each battery cell and records the historical performance of those cells.

Topology System

Features

Multiple modes: grid-connected, off-grid, or on and off-grid modes are available.
Three-level control technology ensures high-quality output of electricity.
The power converter system supports communications including RS485, CAN, Ethernet.
Functions of low voltage: the micro-grid system composed of battery, energy storage inverter, PV solar panel could provide uninterruptible power supply.
100% unbalanced load capacity in off-grid operation.
Continuous 105% rated output power.
Many power storage inverters can be connected in paralleled way to increase capacity of battery system.
AC or DC input is acceptable to keep the normal operation of battery system.
Modular design allows the flexible combination of power conversion system (PCS).
