DC Inverter ke Eng?
A DC inverter, e tsejoang ka tloaelo e le aphotovoltaic (PV) inverter kapamotlakase oa letsatsi, ke sesebelisoa sa elektronike se matla se tsoetseng pele se fetolelanghona joale (DC) e hlahisoang ke liphanele tsa letsatsi hoalternating current (AC) e loketseng bakeng sa kgokelo ya marangrang kapa tshebediso ya lehae. E le karolo ea mantlha ea mekhoa ea ho hlahisa matla a photovoltaic, inverter e etsa mesebetsi e mengata ea bohlokoa ho kenyeletsaho latela lintlha tse phahameng tsa matla (MPPT), khokahano ea grid, taolo ea boleng ba matla, le ts'ireletso ea sistimi.
Li-inverters tsa sejoale-joale tsa PV li sebetsa ho pholletsa le mefuta ea motlakase oa motlakase ho tloha200V DC ho isa ho 1500V DC, e nang le litekanyetso tsa matla a tsoang ho1kW diyuniti tsa bodulo ho isa ho di-inverters tse bohareng tsa megawate tse ngata. Ho sebetsa hantle ha li-inverters tsa premium ho feta99%, ka katleho ea Europe-weighted (η) ka tloaelo ho tloha97% ho isa ho 98.5%.
Ho fapana le li-converter tse bonolo tsa DC-AC, li-inverters tsa PV li kenyelletsalitsamaiso tse bohlale tsa taolo e tsoelang pele ho ntlafatsa kotulo ea matla, ho lekola bophelo bo botle ba sistimi, le ho netefatsa hore e latela melaoana ea grid e ntseng e fetoha.
