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-touse, 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 is internally protected from a surge or lightning reaching the connection wires. The STEVAL-ISV013V1 demonstration board includes a PLM or ZigBee(R) 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(R) 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(R) PRO network protocol stack. The module features an embedded MPPT (maximum power point tracking) algorithm based on the "perturb and observe" (P&O) technique to September 2011 Doc ID 022189 Rev 1 For further information contact your local STMicroelectronics sales office. 1/5 www.st.com 5 2/5 1 Doc ID 022189 Rev 1 J1- 1 D30 SPV1001D40 1 SPV1001D40 D31 D32 SPV1001D40 J-SPARE2 J-SPARE1 J1+ 1 3m Ohm R6 0805/SMB D8 N.M.
