PROBLEM TO BE SOLVED: To provide a three-input solar inverter apparatus.SOLUTION: A three-input solar inverter apparatus including two maximum power follow-up controllers can be used as one-input, two-input and three-input solar inverters without changing spatial hardware by embodying a connection box function by including diodes and fuses in an inverter apparatus without embodying many input ports for respectively inputting DC power outputted from solar modules by a connection box different from the inverter apparatus. When using the three-input solar inverter apparatus as one-input solar inverter, efficiency of the inverter is improved by making it possible to remove loss of diodes. |
