Hybrid Power Conversion System (PCS) with Solar Access
Hybrid power conversion system (PCS) with solar access consists of PV control modules and bidirectional DC/AC converter. PV modules increase the voltage produced by solar panel for bidirectional AC/DC converter or to charge battery. The PV controller in PV modules will make full use of the maximum power point (or MMP) to give full play to solar power. Bidirectional AC / DC converter can achieve the power conversion between DC and AC. Furthermore, it can convert AC to DC to charge battery, and convert DC to AC to provide power to loads or back feed the grid. In addition, the hybrid power conversion system with solar access is easy for installation and maintenance.
Bidirectional AC/DC module
Bidirectional AC / DC converter can do the power conversion between DC and AC. Additionally, it can convert AC to DC to charge battery, and convert DC to AC to power to loads or back feed the grid.
Static Transfer Switch
Static Transfer Switch could be shifted within 10ms automatically. Under normal operating condition, the switch is on. When mains power fails, the switch would turn off and the battery system thus shifts to off-grid modes to power loads.
Monitoring System
The system monitors each individual battery cell and records its historical performance.
Maximum Power Point Tracking
PV modules increase the voltage produced by solar panel for bidirectional AC/DC converter or to charge battery. The PV controller in PV modules can make full use of the maximum power point (or,MMP) to give full play to solar power.
