*1: The Li-lon battery usually contain two mainstream type: LFP and Ternary Lithium battery.
*2: When the input voltage is greater than 980V. the inverter will enter standby mode. and when the voltage returns to below 95oV the inverter will return to normal operation.
*3: Please refer to the user manual for the MPPT Voltage Range at Nominal Power.
*4: For Brazil and Chile, the Max. Power is the same with the Nominal Power
*5: For Brazil, for 12K, 15Kand 20K, the Max. Current to Grid is 18.2A@220V, 22.7A@220V and 30.3A@220V respectively.
*6: For Brazil, for 12K, 15K and 20K, the Battery Reverse Polarity Protection is integrated
*7:AFCl is integrated in Brazil
*8: 5K is expected to be available around October.
