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.
