Inverter		Instruction
SUN2000-2/3/3.68/4/4.6/5/6KTL SUN2000-2/3/3.68/4/4.6/5/6KTL-L1	Link	Access the Power Adjustment screen on the FusionSolar app Select Power adjustment Select Grid-tied point control Select Active Power Change Control mode to Grid-connected with zero power Change Closed-loop controller: Inverter if only 1 inverter in the system SDongle/SmartLogger if more than 1 inverter Change Limitation mode: Total power – max self-consumption, inverter output = sum of power in each phase, but power injection to grid possible in case of big unbalance of loads. Single-phase –inverter output = 3 x power in the least consuming phase, therefore, no injection at all
