Sravana Sameeralu Serial 4th Technology Definition
Low-Voltage Residential BESS (≤ 60 V)
Chivakwa chakagoverwa umo 40-60 V bhatiri module inofananidzwa pamwero wekhabhineti. Iyo yakasarudzika DC-DC nhanho mukati meiyo hybrid inverter inowedzera bhatiri voltage kune yemukati DC-bhazi, uko inosanganiswa nePV simba risati rapinda.
High-Voltage Residence BESS (85–600 V)
Iyo yepakati, yakatevedzana-yakaturikidzana architecture: akawanda mamodule akabatana munhevedzano kugadzira 85-600 V bhatiri tambo. A high-voltage control box (yakabatanidzwa fuse, contactors, pre-charge uye isolation monitoring) inodyisa tambo yakananga muinverter's DC-bhazi kuburikidza nebhaki / boost regulator.
Kuenzanisa Kwekuita
Low-Voltage
Pros
- Kuwedzera-low-voltage (ELV) kuchengetedza hurumende; zvishoma kubata-ngozi
- Modular, plug-uye-kutamba kuisirwa; yakaderera CapEx yemhuri dzine bhajeti
- Yakareruka yakafanana BMS algorithms
Cons
- Kurasikirwa kwepamusoro kwekudzivirira (I²R) → 3–5 % chirango chesimba
- Simba rekuburitsa shoma; haikodzeri> 3 kW mitoro yakamira
- Kureba kwenguva yakareba simba kudhiraivha kune anofanana mabhuroko anowedzera magadzirirwo ekugadzirisa
High-Voltage
Pros
- Kusvika pa96% yekufamba-famba zvakanaka (RTE) nekuda kwekudzikira kwemvura uye kuderedzwa kwemafuta
- Inoenderera mberi 5-10 kW kubuda; inotsigira HVAC, pombi yekupisa kana pakarepo-yemvura-inopisa kupisa
- Diki tambo muchinjiko-zvikamu → yakareruka, yakawanda compact wiring harness uye inverter magineti
Cons
- Inoda nyanzvi dzeHV dzakasimbiswa; yakaoma IEC 63056 / UL 9540A yekuedza moto
- Stringent cell-level voltage uye tembiricha inoenderana; advanced BMS ine inoshanda kuenzanisa
- Yakakwira kumberi mutengo (bhatiri + HV kuchengetedza giya)
Application Scenarios
Low-Voltage
- Dzimba diki / dzimba dzekupera kwevhiki dzine <10 kWh zuva nezuva mutoro uye isina yakakwirira-inrush midziyo
- Pilot kana zvivakwa zvekurojesa uko kubviswa nekukurumidza kunokosheswa pamusoro pepamusoro pekuita
High-Voltage
- Dzimba dzepakati-kusvika-dzikuru dzemhuri imwe chete dzine chinangwa> 90 % simba rekuzvishandisa.
- Remangwana-proofing yeV2H / backup jenareta yekubatanidza kana 15 kWh-30 kWh ekuwedzera mapaketi
Levelisad Cost of Storage (LCOS)
Low-Voltage
Yakaderera CAPEX, asi 5 % -8 % yekuwedzera kurasikirwa kwesimba pakutenderera uye kukurumidza kutsiva sero kunogona kusimudza gumi-makore LCOS ne12-15 % maringe neHV.
High-Voltage
20–30 % CAPEX premium inoderedzwa ne> 90 % RTE uye 8 000–10 000 kutenderera hupenyu; kutyora-nyangwe kazhinji inowanikwa mugore 5-6 pasi peGerman kana California TOU tariff.
Chengetedzo & Kutevedza Kodhi
Low-Voltage
Inowira pasi peSELV (Safety Extra-Low Voltage); hapana inosungirwa arc-fault disconnection; DIY-inoshamwaridzika munzvimbo dzakawanda.
High-Voltage
Inofanirwa kusangana neIEC 62109-1/2, UL 1973 uye yemuno HV yekuisa makodhi; inosungirwa kutariswa kwekudzivirira, arc-fault circuit interruption (AFCI) uye shutdown protocols <5 s mushure mekuona kukanganisa.
Mhedziso:
Sarudza yakaderera-voltage kana capital yakamanikana, mitoro yakareruka uye kumhanya kwekuisa kwakakosha. Taura high-voltage kana iwe uchida zvakanyanya kunyatsoshanda, yakakwirira ipapo simba uye yakaderera yehupenyu hwese mutengo pakWh. Chero nzira, enzanisa dhizaini kune iyo mutoro profile-kwete imwe nzira yakatenderedza-uye simbirira pane yakasimbiswa yekubatanidza kuvhura iyo yakazara waranti kukosha kwekugara kwako BESS.
