Note a: The maximum input voltage is the maximum DC input voltage that the inverter can withstand. If the input voltage exceeds this value, the inverter may be damaged.

Note b: The maximum input power of an MPPT circuit is 21.6 kW. If the input power exceeds this value, the inverter may limit the output power of PV modules.

Note c: If the input voltage is beyond the MPPT voltage range, the inverter cannot work properly.
