PV Combiner Box yog dab tsi?
A PV mixer lub thawvyog huab cua tsis zoo hluav taws xob thaiv nruab nrab ntawm lub hnub ci PV array thiab lub inverter. Nws sau cov DC tso zis los ntawm ntau lub hnub ci vaj huam sib luag cov hlua, sib txuas rau hauv ib qho kev sib txuas, thiab xa cov hluav taws xob ua ke mus rau lub inverter los ntawm ib qho kev sib txuas.
Yog tsis muaj lub thawv PV sib txuas, lub hnub ci loj loj yuav tsum tau khiav ib khub ntawm DC cables los ntawm txhua txoj hlua ncaj qha mus rau lub inverter. A 12- hlua kev lag luam ru tsev yuav txhais tau tias 24 tus neeg DC cables - kev teeb tsa npau suav phem thiab qhov tseem ceeb ntawm kev xaim tsis raug thiab kev pheej hmoo txhaum. Lub thawv PV combiner daws qhov no los ntawm centralizing tag nrho cov hlua txuas rau hauv ib qho kev sib koom ua ke, tiv thaiv, thiab kev pabcuam.
Tshaj qhov yooj yim cable consolidation, niaj hnubphotovoltaic combiner lub thawvyog ib qho kev tiv thaiv tag nrho: nws muaj DC PV fuses uas tiv thaiv txhua txoj hlua ntawm nws tus kheej, Hom 2 DC SPD uas tiv thaiv hluav taws xob thiab hluav taws xob puas tsuaj, thiab DC rho tawm hloov pauv uas tso cai rau kev nyab xeeb ntawm tag nrho cov array rau kev saib xyuas - tag nrho hauv ib qho IP65 weatherproof enclosure.
