STEVAL-ISV013V1
250 W DC-DC solar module demonstration board
for distributed photovoltaic architecture
Features
■Input voltage range from 10 V to 45 V
■Output voltage range from 350 V to 430 V
■Digital control section managed by the STM32
■Several I/O connectors to be connected to the
photovoltaic panel (input side) and the inverter
(output side)
■Ready to be connected to a PLM or ZigBee®
external module for communication
■Possibility to meter and monitor the status of
the panel
■Fire and anti-theft protections
■RoHS compliant
Description
The STEVAL-ISV013V1 demonstration board is a
fully integrated module designed for a smart
junction box in distributed photovoltaic
architecture. The module represents an easy-to-
use, fully-protected solution to implement precise
photovoltaic panel control, diagnostics and
protection.
The STEVAL-ISV013V1 demonstration board is
the base element for a new photovoltaic panel
configuration able to increase the panel energy
produced and to simplify the photovoltaic field
design and implementation. Furthermore, the
maintenance cost will be reduced as the device is
able to monitor the status of the individual panels
and to communicate these data to a remote
control unit. The STEVAL-ISV013V1
demonstration board uses an isolated converter,
which is the input of the panel output. This voltage
is stepped up to the voltage defined by the
inverter, needed to create a sinusoidal output with
a magnitude big enough to transfer energy to the
grid.
The module features an embedded MPPT
(maximum power point tracking) algorithm based
on the “perturb and observe” (P&O) technique to
search for the best operating point of the panel in
order to maximize the energy produced in every
environmental condition.
The module is internally protected from a surge or
lightning reaching the connection wires.
The STEVAL-ISV013V1 demonstration board
includes a PLM or ZigBee® module for
communication. The PLM is supported by a
proprietary protocol stack for networking. A
gateway to RS485 in modbus is available. The
unit is designed to operate in a harsh
environment, offering a high level of protection
and very high reliability.
The ZigBee® module is based on system-on-chip
(SoC) technology, integrating both IEEE 802.15.4
radio transceiver and computing capabilities and
is designed to run a fully compliant ZigBee® PRO
network protocol stack.
