2017 NEC 690.12 Kev Tawm Sai Sai - Hloov Hloov Tseem Ceeb

NEC 2017 hu rau kev hloov qib hauv kev kaw nrawm nrawm ntawm cov hnub ci hloov chaw ntawm NEC 2014's array qib ntawm kev yuav tsum tau kaw.

Pib txij Lub Ib Hlis Tim 1 2019 thaum NEC 2017 pib siv mus rau hauv cov kev cai lij choj, txhua tus coj nyob hauv thaj tsam 1-ft ciam yuav tsum raug txo mus rau 80V lossis tsawg dua hauv 30 vib nas this ntawm kev kaw nrawm.

Rapid Shutdown

Qhov feem ntau ua hauj lwm-nqi thiab tsuas yooj yim kaw qhov kev daws teeb meem

Ntawm ib qho micro-inverters thiab cov ua kom zoo dua, BFS kaw nrawm dua ib qho kev xaiv ntxiv uas yog tus nqi tsim nyog thiab kev daws teeb meem yooj yim ntawm kev kaw nrawm nrawm, nrog khawm zoo hloov mus rau kev lag luam saum ru tsev thiab tseem muaj cov roj teeb-hauv tshuab suav nrog xws li cov fais fab sab nraud.

Raws li peb tuaj yeem pom BFS chav nyob tsis tas yuav wifi nrog lub hnub ci inverter.

Lest poob lub zog poob los ntawm inverter 24V mus rau qhov hloov thaum muaj xwm ceev, uas yog kev sib txuas ntawm cov tshuab kaw nrawm thiab inverter.

3 txoj hauv kev los kaw cov vaj huam sib luag rau 0V, ntau dua NEC2017.

* Kev tuav thaum muaj xwm ceev kaw

* Tsis siv neeg kaw ntawm inverter AC fais fab tuag

* Tsis siv neeg kaw thaum lub sijhawm kub tshaj 85 ℃

Plug thiab ua si yooj yim installation

Txhua pawg BFS kaw nrawm ua haujlwm ob lub hnub ci ci thiab muab tso rau tom qab ntawm lub panels thiab txuas rau tus ncej vaj huam sib luag.

Qhov zoo txaus rau 800W DC zog, yog li haum rau feem ntau ntawm cov hnub ci vaj huam sib luag uas tam sim no muaj nyob rau ntawm kev ua lag luam.

Cov koog BFS tau txuas nrog hauv kev siv cov khoom siv sib txuas thiab txuas ua ke thiab cov teeb liab cable yog tom qab coj mus rau qhov chaw nyab xeeb, uas tuaj yeem nyob txhua qhov chaw yooj yim mus cuag.

Sai li qhov kev nyab xeeb hloov tau raug qhib, BFS "txiav-nqis" lub hnub ci vaj huam sib luag los ntawm kev cais tawm tag nrho DC cabling hauv lub tsev txoj cai rov qab rau sab nraub qaum ntawm cov teeb tsa ua haujlwm.

Nyob hauv cov tsev loj dua, muaj ntau cov chav tsev nyob, ntau tus Chav Nyob Nyab Xeeb yuav nyob hauv ntau qhov chaw ntawm lub tsev, lossis hauv cov plag tsev sib txawv raws li qhov xav tau.
