Flatpack2 PS System ~ Hybrid Solar
The example in Figure 2 represents a typical hybrid, solar Flatpack2 PS system for DC
power supply of telecom and industrial equipment.
The system is fed from strings of solar panels (DC feed), and uses a diesel generator as
AC feed backup at night and during cloudy days, thus ensuring extra battery charging.
Extra AC feed backup can also be supplied by wind turbines or from the Mains grid.
The hybrid, solar system consists of paralleled solar chargers and rectifiers in power
shelves, Smartpack2-based system controllers and DC distribution unit. Battery banks,
LVD contactors, etc. are typically also a part of the system.
The Smartpack2 Master controller serves as the local user interface, while the
Smartpack2 Basic controller monitors the system’s internal wiring. The I/O Monitor2 CAN
node provides the system with input monitoring and output controlling signals.
You can configure the system from a standard web browser, via WebPower, or installing
the PowerSuite application in a computer.
