(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, integr ating both ieee 802.15.4 radio transceiver and co mputing capabilities and is designed to run a fully compliant zigbee ? pro network protocol stack.
