STEVAL-ISV013V1: 350 ~ 450V @ 800mA, 10 ~ 55V in

The STEVAL-ISV013V1 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, diagnostic and protection.

The STEVAL-ISV013V1 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 realization. Furthermore, the maintenance cost is reduced thanks to the possibility of monitoring the individual panel status and to communicate these data to a remote control unit. The demonstration board realizes an isolated converter to be connected at the output of a single PV panel for distributed MPPT. This voltage is stepped up to the voltage, defined by the inverter, needed to realize a sinusoidal output with a magnitude big enough to transfer energy in the grid.

The module features an embedded MPPT (maximum power point tracking) algorithm based on the “Perturb and Observe” (P and 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 against surge or lightning reaching the connection wires. The STEVAL-ISV013V1 can integrate a PLM or ZigBee® for communication. The PLM is supported by a proprietary protocol stack for networking. 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.
