Integrated Power Conversion System (PCS) with Wide Voltage Range
The bidirectional converter can convert DC into AC and AC into DC. It can both convert AC to 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 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 DC input range of 200V-900V, which can better suit the charging and discharging needs of different battery combinations. The power conversion system is characterized by a modular design, which allows flexible battery pack connections for the same power output. All of these can greatly increase the service life of batteries.
Application
- To meet industrial and commercial demand management, peak shaving
- To conduct peak shaving during high power demand periods and valley filling during off-peak hours
- To serve as backup power
- Power storage, voltage peak and frequency regulation
- To form a microgrid 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 converter is a RS485 / Ethernet Converter and it is compatible to the power grid.
- Functions of low voltage ride through and reactive power compensation;
- Off-grid function: 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 storage PCS.
