Buku Lotsogolera Kusankha Mabatire a Ma Solar Systems a Pakhomo
Kukhazikitsa makina oyendera dzuwa kunyumba sikuti kungosankha ma solar panels ndi inverter yokha. Chimodzi mwazinthu zofunika kwambiri kuti makinawo akhale omasuka komanso odalirika ndi batire. Batire imasunga mphamvu kuchokera ku ma solar panels kuti igwiritsidwe ntchito usiku, masiku a mitambo, kapena nthawi yamagetsi (ya makina omwe ali ndi chithandizo chowonjezera). Popeza mtengo wake ndi gawo lofunika kwambiri la ndalama zomwe zayikidwa, kusankha batire kuyenera kuchitidwa mosamala, osati kungotsatira zomwe zikuchitika.
Nkhaniyi ikuthandizani kumvetsetsa mitundu ya mabatire, momwe mungawerengere zofunikira pa mphamvu, magawo ofunikira aukadaulo, malangizo osamalira ndi zolakwika zomwe zimachitika kawirikawiri.
1. Mvetsetsani Cholinga cha Dzuwa Lanu
Gawo loyamba ndikudziwa zosowa zanu zazikulu:
1. Sungani ndalama zamagetsi (zolumikizidwa ndi gridi/zosakanizidwa): Mukufuna kuchepetsa kugwiritsa ntchito magetsi anu mukadali olumikizidwa ku gridi. Mabatire nthawi zambiri amagwiritsidwa ntchito posuntha katundu (pogwiritsa ntchito mphamvu ya batri nthawi yomwe magetsi akuyenda kwambiri) kapena ngati chothandizira magetsi akazima.
2. Kusunga nthawi yogwiritsira ntchito magetsi akazima: Cholinga chachikulu ndi kuigwiritsa ntchito kuti magetsi aziyaka nthawi zonse (magetsi, firiji, Wi-Fi, mapampu ena amadzi).
3. Off-grid (yopanda PLN): Batire imakhala pakati pa dongosolo chifukwa katundu yense amadalira kusungira mphamvu.
Cholinga ichi chimatsimikizira kukula kwa batri, kapangidwe koyenera, ndi zofunikira za mphamvu yapamwamba (kukwera) zomwe iyenera kupirira.
2. Dziwani Mitundu Yodziwika ya Mabatire a Solar Yapakhomo
a) Lead-acid (Yonyowa, AGM, Gel)
Mabatire a lead-acid amagwiritsidwabe ntchito chifukwa poyamba amakhala otsika mtengo, koma ali ndi zofooka:
– Ubwino: mtengo wotsika woyambira, wosavuta kupeza, ukadaulo wokhwima.
– Zoyipa: nthawi yogwira ntchito yafupika, yolemera komanso yokulirapo, mphamvu yochepa yochaja, komanso yosamva kutulutsa madzi ambiri.
– Zindikirani: Maselo onyowa amafunika kusamalidwa (madzi a batri ndi mpweya wabwino). AGM/Gel ndi "opanda kukonza" koma ali ndi zoletsa za DoD.
Lead-acid ndi yoyenera kwambiri pa bajeti yochepa komanso kugwiritsa ntchito pang'ono, koma nthawi zambiri mtengo wonse wa umwini ungakhale wokwera mtengo chifukwa umafunika kusinthidwa pafupipafupi.
b) Lithium-ion (makamaka LiFePO4/LFP)
Pa makina amakono a dzuwa apakhomo, LiFePO4 (Lithium Iron Phosphate) ndiye chisankho chodziwika kwambiri.
– Ubwino: nthawi yayitali yogwiritsira ntchito, DoD yapamwamba (yogwiritsidwa ntchito m'nyumba), magwiridwe antchito apamwamba, yopepuka komanso yaying'ono, komanso yosakonza kwambiri.
– Zoyipa: mtengo woyambira wokwera, umafuna njira yabwino yoyendetsera mabatire (BMS).
– Dziwani: LFP nthawi zambiri imakhala yotetezeka pa kutentha kuposa mitundu ina ya lithiamu, kotero nthawi zambiri imasankhidwa kuti igwiritsidwe ntchito kunyumba.
Ngati mukufuna kudalirika komanso kugwiritsa ntchito tsiku ndi tsiku (monga kuyendetsa batri usiku uliwonse), LFP nthawi zambiri imakhala yotsika mtengo pamapeto pake.
3. Magawo Ofunika: Kutha (kWh), Mphamvu (kW), ndi DoD
Anthu ambiri amalakwitsa kungoyang'ana "Ah" kapena "kukula kwa batri" osamvetsetsa mfundo zitatu zofunika izi:
– Mphamvu (kWh): kuchuluka kwa mphamvu komwe kungasungidwe. Izi zimatsimikizira kutalika kwa nthawi yomwe katunduyo angagwiritsidwe ntchito.
– Mphamvu yotulutsa (kW): kuchuluka kwa katundu womwe makina angagwiritse ntchito nthawi imodzi. Izi zimadalira mphamvu ya batri ndi inverter yopereka mphamvu yamagetsi yapamwamba.
– Kuzama kwa Kutulutsa Mphamvu (DoD): kuchuluka kwa mphamvu yogwiritsidwa ntchito. Mwachitsanzo, batire ya 10 kWh yokhala ndi DoD ya 90% imatanthauza kuti mphamvu yogwiritsidwa ntchito bwino ndi ~9 kWh.
Batire ya "high kWh" sikutanthauza kuti imapereka mphamvu yapamwamba kwambiri. Onetsetsani kuti batireyo ikugwirizana ndi zosowa za magetsi za m'nyumba mwanu.
4. Momwe Mungawerengere Zofunikira pa Mphamvu ya Batri
Njira yothandiza: kudziwa katundu wofunikira komanso nthawi yobwezera yomwe mukufuna.
Gawo 1: Lembani ndalama zofunika (chitsanzo)
– Nyali: 100 W yonse
– Firiji: 150 W (chiwerengero chapamwamba chingakhale chokwera kwambiri compressor ikayamba)
– Wi-Fi + zipangizo zazing'ono: 30 W
– TV: 80 W
Chiwerengero chapakati: 360 W
Gawo 2: Dziwani nthawi yake
Mwachitsanzo, ngati mukufuna kusunga maola 8:
Mphamvu = 360 W × maola 8 = 2.880 Wh = 2,88 kWh
Gawo 3: Lowetsani zinthu zotayika ndi zosungira
Ganizirani kutayika kwa inverter ndi makina (monga 10–15%).
2,88 kWh × 1,15 ≈ 3,31 kWh
Gawo 4: Lumikizani ndi DoD
Ngati mukugwiritsa ntchito LFP DoD 90%:
Kuchuluka kwa mphamvu = 3,31 / 0,90 ≈ 3,68 kWh
Chifukwa chake, batire limafunika mphamvu pafupifupi 4 kWh poyerekeza ndi zomwe zili pamwambapa (ndi bwino ngati muwonjezera mphamvu yosungira malinga ndi momwe mumagwiritsira ntchito).
Pa makina omwe amagwiritsidwa ntchito tsiku ndi tsiku (osati nthawi ya mdima yokha), mutha kuwerengera mphamvu yausiku yomwe mukufuna kuti batire igwire, mwachitsanzo kugwiritsa ntchito kuyambira 6:00 PM mpaka 6:00 AM.
5. Volti ya System: 12V, 24V, kapena 48V?
Kwa nyumba, makina a 48V nthawi zambiri amakhala ogwira ntchito bwino komanso otetezeka (magetsi otsika mphamvu yomweyo). Makina a 12V/24V ndi oyenera kugwiritsidwa ntchito pang'ono, monga magetsi osavuta kapena nyumba zazing'ono.
Ngati mukufuna inverter ya 3 kW kapena kuposerapo, 48V nthawi zambiri ndi chisankho chanzeru chifukwa:
- zingwe siziyenera kukhala zazikulu ngati makina a 12V,
- kutayika kochepa,
- dongosolo lokhazikika kwambiri la katundu wolemera kwambiri.
6. Udindo wa BMS ndi Kugwirizana ndi Inverter
Pa mabatire a lithiamu, BMS (Battery Management System) ndi "ubongo" womwe umateteza maselo ku mphamvu yochulukirapo, kutulutsa mphamvu mopitirira muyeso, mphamvu yochulukirapo, ndi kutentha kwambiri. Mukasankha batire, onetsetsani kuti:
- BMS imathandizira mphamvu yofunikira yolipirira/yotulutsa mphamvu,
- pali chitetezo cha kutentha,
– ngati makina anu ndi osakanikirana, onani momwe kulumikizana kukuyenderana ndi inverter (CAN/RS485).
Kugwirizana kumeneku kumathandiza inverter kuwerenga SOC (mkhalidwe wa chaji) molondola ndikuwongolera chaji moyenera.
Ngati sichikugwirizana, chingathe kugwirabe ntchito pa makina ena, koma kukhazikitsa kuyenera kusamala kwambiri kuti kupewe kuwerengedwa kolakwika kwa ma SOC.
7. C-Rate: Kutha kwa Kuyenda kwa Current
C-rate imafotokoza momwe batire ingayambitsire/kutulutsa mphamvu mwachangu. Chitsanzo:
– Batire ya 10 kWh yokhala ndi 0,5C imatha kupereka mphamvu pafupifupi 5 kW mosalekeza.
- Ngati muli ndi katundu wokwera kwambiri (mapampu amadzi, ma air conditioner ena), onetsetsani kuti batire ndi inverter zimatha kuthana ndi kukwera kwa madzi.
Komanso samalani ndi mphamvu yopitilira komanso mphamvu ya batri (ngati gawo la batri likupereka izi), osati mphamvu yokha.
8. Moyo wa Mzunguliro, Chitsimikizo, ndi Kutentha Kogwira Ntchito
Mabatire samangonena za "ma kWh angati," komanso nthawi yomwe amakhala. Onani:
- Moyo wa kuzungulira: mwachitsanzo ma cycle 4.000–6.000 pa DoD inayake.
– Chitsimikizo: nthawi zambiri mabatire a lithiamu amakhala a zaka 5–10 ndipo mphamvu yake imachepa.
– Kutentha kogwira ntchito: Kutentha kwambiri kumathandizira kuwonongeka. Onetsetsani kuti batire yayikidwa pamalo opumira bwino komanso kutali ndi dzuwa.
M'madera otentha, kusamalira kutentha n'kofunika kwambiri. Kuyika batri pamalo ozizira komanso ouma (monga chipinda chamagetsi) kudzawonjezera nthawi yake yogwira ntchito.
9. Malangizo Osankha Mbali Yothandiza (Mndandanda Wowunika)
Musanagule, gwiritsani ntchito mndandanda wotsatirawu:
1. Dziwani zofunikira za kWh (kutengera katundu ndi nthawi).
2. Onetsetsani kuti mphamvu ya peak (kW) ndi yokwanira kuyambitsa firiji/pompu.
3. Sankhani LFP ngati batire imagwiritsidwa ntchito pafupipafupi ndipo mukufuna kukhala ndi moyo wautali.
4. Onetsetsani kuti inverter ikugwirizana ndi batri (makamaka makina osakanizidwa).
5. Sankhani magetsi a 48V a makina apakati ndi akuluakulu a nyumba.
6. Chongani chitsimikizo, satifiketi, ndi mbiri ya mtundu wa kampani.
7. Ganizirani za malo, mpweya wabwino ndi chitetezo cha kukhazikitsa.
8. Konzani chitetezo: fuse ya MCB/DC, chosungunula, ndi zingwe motsatira miyezo.
10. Zolakwa Zofala
Zolakwika zina zomwe zingayambitse mavuto a dongosolo mwachangu:
– Mphamvu ya batri ndi yochepa kwambiri, kotero nthawi zambiri imatha ndipo imafupikitsa nthawi yake yogwira ntchito.
- Kunyalanyaza mphamvu yapamwamba, zomwe zimapangitsa kuti inverter igwe pansi pamene katundu akuyamba.
- Kusakaniza mabatire azaka/mitundu yosiyanasiyana (makamaka lead-acid) kumachepetsa magwiridwe antchito.
– Zokonzera zochajira sizolondola (voltage yodulira ndi mphamvu yamagetsi sizolondola).
- Kusayika bwino chingwe, zomwe zimayambitsa kutentha, kutayika kwa magetsi, komanso chiopsezo cha moto.
Ngati mukukayika, funsani katswiri wodziwa bwino makina a DC ndi miyezo ya chitetezo pakuyika.
Kutseka
Kusankha batire ya solar system yapakhomo ndi kuphatikiza kuwerengera mphamvu, zofunikira pa mphamvu, ndi njira yogwiritsira ntchito (kusunga ndalama, kusunga ndalama, kapena kugwiritsa ntchito gridi yosakhala yamagetsi). Kawirikawiri, mabatire a LiFePO4 amapereka magwiridwe antchito abwino kwambiri komanso moyo wautali wa nyumba zamakono, ngakhale kuti ndalama zoyambira zimakhala zambiri. Komabe, chisankho chomaliza chimadalirabe zofunikira pa kWh, mphamvu yamagetsi (kW), kuyanjana kwa inverter, ndi zinthu zomwe zimayikidwa.
Ngati mukufuna, ndingakuthandizeni kuwerengera kuchuluka kwa batri komwe kumalimbikitsidwa kutengera mndandanda wa zida zanu zapakhomo (kugwiritsa ntchito mphamvu pa chipangizo chilichonse ndi maola ogwiritsira ntchito), kenako ndikupangirani njira yoyenera yogwiritsira ntchito bajeti yanu.
