Pre-commissioning function for automatic validation of system components and cabling during installation and prior to connection to the network. Easy to assemble with 2 people due to lightweight, modular design (each inverter includes 2 or 3 synergy units and one synergy management device). Independent operation of each synergy unit increases uptime and ease of maintenance. Built-in temperature sensors detect wiring faults for increased protection and safety. Built-in arc fault protection and optional fast shutdown. Built-in PID limiting function for maximum system efficiency. Monitored (applicable to DC and AC SPDs only), field replaceable surge protectors for greater withstand of surges caused by lightning or other events: integrated RS485 surge protection and type 2 DC SPD modules, optional type 2 AC SPD. The optional integrated DC kill switch eliminates the need for external DC isolators. Built-in module-level monitoring with Ethernet or cellular communication for full system visibility.
