No ke aha e pono ai e hoʻohana i nā kaula pv DC i nā ʻōnaehana pv?

He nui nā mea kūʻai aku i nā nīnau penei: No ke aha i ka hoʻokomo ʻana i nā ʻōnaehana pv, pono ke hoʻohana ʻana i ka hui like-parallel o nā modula pv i hoʻolaʻa ʻia i nā kaula pv DC ma mua o nā kaula maʻamau?

I ka pane ʻana i kēia pilikia, e nānā mua kākou i ka ʻokoʻa ma waena o nā kaula pv DC a me nā kaula maʻamau.

1. uwea kumu:Ordinary uwea hoʻohana maʻemaʻe keleawe uea, i melemele i ka nana aku a hiki ke hoʻokō wale kumu uila conductivity requirements.The pv DC uwea hoʻohana tinned uea keleawe, a me ka hana i oi paʻakikī ma mua o ka nele keleawe uea. ʻOi aku ka palupalu o ka uea keleawe tinned a maikaʻi ka conductivity uila.Ke hoʻohālikelike ʻia me ka uea keleawe ʻole, hiki iā ia ke pale aku i ka ʻili o ka ʻōpala, a ʻoi aku ka ikaika o kona pale ʻana i ka corrosion a me ke kūpaʻa oxidation, hiki ke hoʻolōʻihi i ke ola lawelawe o nā kaula nāwaliwali o kēia manawa.

2. Insulating shell material:Ordinary cables usually use XLPE insulation sheath.PV DC cables are insulated and sheathed with irradiated cross-linked polyolefin.The key index “irradiation” is usually after irradiated by a radiation accelerator, the molecular structure of the cable. e hoʻololi ʻia nā mea e loaʻa ai ka hana ʻoi aku ka ikaika. No ka laʻana:

3. I ke kiʻekiʻe wela a me ke anuanu kaiapuni, ka puʻe a me ke kuʻekuʻe ikaika e lilo i mea ikaika, a me kekahi degere o ka lapalapa ahi retardant hopena, ka mea hiki ole ke hana i hamama lapalapa, etc. papa hou o ka pale pale insulating ma mua o nā uwea maʻamau.

I ka hōʻuluʻulu ʻana, ʻoi aku ka ikaika o ke ola a me ka lōʻihi o ka pv DC ma mua o nā kaula maʻamau, a he kaula hoʻohui i kūpono no nā ʻōnaehana hana mana pv.No laila, e noʻonoʻo ana i ka palekana a me ka paʻa o ka ʻōnaehana pv, pono ʻoe e koho i kahi ʻoihana.PV DC uwea.

TORCHN makemakehoʻokuʻuʻO 3kw a me 5kw Power frequency inverters ma ʻAukake 1st, me ka hiʻohiʻona kiʻekiʻe, ke kumu kūʻai kiʻekiʻe, a me ka WIFI.Hoʻolālā ʻia e ʻae iā ʻoe e kūʻai i nā huahana pono a nani hoʻi, e hoʻopakele iā ʻoe i ke kumukūʻai a me ka manawa.
