    Sunny Tripower X as System Manager The Sunny Tripower X can be used as System Manager in systems with a total of five SMA inverters and a maximum system size of 135 kVA. When used as System Manager, the Sunny Tripower X in conjunction with an energy meter takes over the control at the point of interconnection and can control up to four lower-level inverters.
  • Page 20 SMA ArcFix SMA ArcFix is an Arc Fault Circuit Interrupter (AFCI). With this function, the inverter effectively detects arcs on the DC side and interrupts them. A detected electric arc causes the inverter to interrupt feed-in operation. To restart feed-in operation, the operational disruption which has occurred must be reset.
