The REbus
TM
Microgrid is the underlying technology that allows for the efficient and robust
interconnection of different types of renewable energy products. This section is informational only and
not required knowledge for operation of your Pika B801 Charge controller.
4.1 Simple and Efficient Power Distribution and Management
The REbus
TM
Microgrid architecture was designed with renewable energy in mind. A clean-sheet
approach to power distribution resulted in the most practical and efficient interconnection technology
available. The REbus
TM
Microgrid operates at variable voltage in a defined band, b/- 180-200 V
relative to ground which simultaneously allows for efficient power transmission, reduced shock hazard,
and simplified electronics for a bidirectional converter such as the B801. The variable voltage
communicates energy availability to the attached REbus
™ devices, which allows for prioritized energy
storage and load shedding. The REbus
TM
Microgrid is designed to support many different types of
renewable energy sources and power converters, as well as accommodating future 380VDC REbus
TM
Microgrid loads that are presently in development.
4.2 Integrated Power Line Carrier (PLC) Communications
The REbus ™ Microgrid standard also specifies an optional power line carrier communication technology
that enables devices on the same REbus™ M icrogrid to communicate with one another. The B801 uses
this capability to gather information about your system such as the status and energy production of your
Pika T701 Wind Turbine or your solar array, which connects to the REbus
™ Microgrid through the Pika
S2001 PV Link.
4.3 REbus ™ Control Protocol (RCP)
REbus ™ Control Protocol (RCP) is a communications protocol developed specifically for the transfer of
data between REbus ™ -compatible power converters and data management products. RCP is an open-
standard protocol which enables independent developers to interface with REbus ™ products and create
software and applications to enhance user experience. Please visit the Pika Energy website to learn
more about RCP and the software applications that are currently available.
