Malo Okhala Ochepa Amagetsi a BESS (≤ 60 V)
Zomangamanga zomwe ma module a batri a 40-60 V amafanana pamlingo wa nduna. Gawo lakutali la DC-DC mkati mwa hybrid inverter limawonjezera mphamvu ya batri kupita ku DC-bus, komwe imaphatikizidwa ndi mphamvu ya PV isanasinthe.
Malo Okhala Okwera Kwambiri BESS (85–600 V)
Zomangamanga zapakati, zotsatizana: ma module angapo amalumikizidwa mndandanda kuti apange chingwe cha batri cha 85-600 V. Bokosi lamagetsi okwera kwambiri (ma fuse ophatikizika, zolumikizira, zowongolera zisanayambike ndi kuyang'anira kudzipatula) amadyetsa chingwecho mwachindunji mu inverter's DC-bus kudzera pa buck/boost regulator.
Kufananiza Magwiridwe
Low-Voltge
Ubwino
- Dongosolo la chitetezo chowonjezera-low-voltage (ELV); chiopsezo chochepa chokhudza
- Kuyika modular, pulagi-ndi-sewero; kutsika kwa CapEx kwa mabanja omwe alibe bajeti
- Ma algorithms osavuta ofanana a BMS
kuipa
- Kutayika kwamphamvu kwambiri (I²R) → 3–5 % chilango cha mphamvu
- Mphamvu zochepa zotulutsa; zosayenera pa katundu wopitilira 3 kW
- Kusuntha kwamphamvu kwanthawi yayitali kudutsa midadada yofananira kumawonjezera kukonzanso
High-Voltge
Ubwino
- Kufikira 96 % paulendo wobwerera (RTE) chifukwa cha mafunde otsika komanso kuchepa kwa kutentha
- Kutulutsa kopitilira 5-10 kW; imathandizira HVAC, pampu yotentha kapena mawotchi otenthetsera madzi pompopompo
- Tizigawo zing'onozing'ono zodutsa zingwe → zopepuka, zolumikizana kwambiri ndi ma wiring harness ndi ma inverter maginito
kuipa
- Pamafunika akatswiri ovomerezeka a HV; Kuyesa kwamoto kwa IEC 63056 / UL 9540A
- Mphamvu yamagetsi ya cell-level ndi kutentha kofananira; BMS yapamwamba yokhala ndi kusinthasintha kogwira
- Mtengo wapamwamba wakutsogolo (batri + chitetezo cha HV)
Zochitika za Ntchito
Low-Voltge
- Zipinda zing'onozing'ono / nyumba zakumapeto kwa sabata zokhala ndi <10 kWh katundu watsiku ndi tsiku komanso zopanda zida zowononga kwambiri
- Malo oyendetsa ndege kapena malo obwereketsa komwe kuchotsedwa mwachangu kumayesedwa pamtengo wapamwamba kwambiri
High-Voltge
- Nyumba zokhala ndi mabanja apakati mpaka zazikulu zomwe zimangofuna > 90 % kugwiritsa ntchito mphamvu
- Kutsimikizira kwamtsogolo kwa V2H / kuphatikiza kwa jenereta zosunga zobwezeretsera kapena mapaketi okulitsa a 15 kWh–30 kWh
Leveld Cost of Storage (LCOS)
Low-Voltge
Kutsika kwa CAPEX, koma 5 % -8 % yowonjezera kutayika kwa mphamvu pakazungulira ndikusintha ma cell koyambirira kumatha kukweza LCOS yazaka 10 ndi 12-15 % motsutsana ndi HV.
High-Voltge
20–30 % CAPEX premium kuchotsera ndi > 90 % RTE ndi 8 000–10 000 moyo wozungulira; kusweka-ngakhale kumapezedwa mchaka cha 5-6 pansi pa mitengo ya TOU yaku Germany kapena California.
Chitetezo & Kutsata Malamulo
Low-Voltge
Imagwera pansi pa SELV (Safety Extra-Low Voltage); palibe kulumikizidwa koyenera kwa arc-fault; DIY-ochezeka m'malo ambiri.
High-Voltge
Ayenera kukwaniritsa IEC 62109-1/2, UL 1973 ndi ma code oyika a HV am'deralo; Kuwunika kovomerezeka kovomerezeka, kusokoneza kwa arc-fault circuit (AFCI) ndi ma protocol otseka <5 s pambuyo pozindikira zolakwika.
Pomaliza:
Sankhani low-voltage likulu likakhala lolimba, katundu ndi wopepuka komanso kuthamanga kwa kukhazikitsa ndikofunikira. Tchulani magetsi okwera kwambiri mukafuna kuchita bwino kwambiri, mphamvu yanthawi yomweyo komanso mtengo wotsikitsitsa wa moyo wanu pa kWh iliyonse. Mulimonse momwe zingakhalire, fananizani zomanga ndi mbiri ya katundu - osati njira ina yozungulira - ndikulimbikira kuphatikizika kovomerezeka kuti mutsegule chitsimikiziro chonse cha BESS yanu.
