- Khoom Taw qhia
Lub thawv PV AC combiner feem ntau yog siv nyob rau hauv loj -scale photovoltaic fais fab nroj tsuag, nyob nruab nrab ntawm lub inverters (uas hloov DC rau AC) thiab cov kauj ruam - nce transformer. Nws lub luag haujlwm tseem ceeb yog uamuab cov AC outputs los ntawm ntau lub inverters ua ntej faib lub zog sib sau ua ke.
Muab ntau tshaj/luv- tiv thaiv Circuit Court, saib xyuas lub zog zoo, thiab kev ua raws li kab sib chaws.

Nco tseg:
DC Combiner Box: Rau txoj hlua -raws li PV systems, kom DC- sab kev nyab xeeb.
AC Combiner Box: Rau ntau-inverter systems (piv txwv li, ua lag luam ru tsev), optimizing kab sib txuas.
DC Combiner Boxes tuav PV hlua aggregation thiab tiv thaiv (pem hauv ntej-kawg).
AC Combiner Boxes tswj cov zis inverter thiab daim phiaj sib cuam tshuam (rov qab- kawg).
Loj - nplai / kev lag luam feem ntau siv ob qho tib si rau qhov kawg - mus rau - kawg kev nyab xeeb thiab kev ua tau zoo.
Daim ntawv thov
● Kev lag luam / kev lag luam PV(ntau -inverter parallel systems)
● PV + lub kaw lus cia(bidirectional zog tswj)
● Microgrids(on/off{0}}grid switching)
● Daim ntawv thov ib puag ncig tshwj xeeb(Offshore PV, Siab -qhov siab version, suab puam fais fab nroj tsuag)
