Ho bohlokoa ho khetha boholo bo nepahetseng ba motlakase oa letsatsi - mme ke e 'ngoe ea lipotso tse atileng haholo: ke hloka saizi efe ea motlakase ea letsatsi? Hore na o kenya sistimi e marulelong California, o matlafatsa moaho o hole oa Alberta, kapa o etsa boholo ba setsi sa sechaba sa Rajasthan, ho se lokisa ho bolela katleho, polokeho le ROI.
Ha re ikakhele ka setotsoana mererong ea mohato ka mohato, lipalo-palo, le hore na ke eng e susumetsang boholo ba inverter.
1. Tseba Kakaretso ea Matla a Solar Panel ea Hao
Qala ka ho tseba bokhoni ba phanele ea hau ea li-watts (W). Ka mohlala:
- Sistimi e tloaelehileng ea 6 kW Los Angeles e kanna ea sebelisa liphanele tse 15 × 400 W = 6,000
- Mohaho oa khabinete ea 3 kW Northern Ontario e kanna ea ba liphanele tse 10 × 300 W = 3,000
Potso eo u lokelang ho e botsa: Tekanyetso ea inverter e lokela ho ba haufi hakae le phanele ea metsi? Hantle ho 80-110%, ho lefella tlhahiso e feteletseng ea phanele ka khanya ea letsatsi le ho qoba ho sekisetsa ts'ebetso ea inverter.
2. Khetha Tekanyetso e Loketseng ea Inverter
Mona ke kamoo boholo ba inverter bo amanang ka teng:
- Sistimi e nyane (2–5 kW):
Liphanele: 3,000 - 6,000 W
Inverter: 3,000 W ho isa ho 5,500 W
- Sistimi e mahareng (6–10 kW):
Liphanele: 6,000 - 10,000 W
Inverter: 5,500 W ho isa ho 8,000 W (boholo bo bong ho ea ho 5 kW ho latela moriti)
- Sistimi e kholo (10–20 kW):
Liphanele: 10,000 - 20,000 W
Inverter: inverter e le 'ngoe kapa tse peli tsa 10 kW-15 kW tse kopantsoeng
Ho kenyelelitsoe matla a matla a letsatsi a 12 kW polasing e haufi le Berlin ho sebelisitse inverter ea 10 kW e nang le liphetho tse ntle haholo - ho boloka lidolara tse makholo a 'maloa ho theko ea pele mme ho ntse ho ngolisa tlhahiso e phahameng.
3. Lekanya Litlhoko tsa Mojaro, eseng Panel Watts
Ha se feela ka khanya ea letsatsi - litaba tsa ts'ebeliso le tsona. Haeba ntlo ea hau e sebelisa 7 kWh letsatsi le leng le le leng ka meroalo e mengata e fapaneng ea tlhoro, sesebelisoa sa 7 kW se fana ka sebaka sa ho boloka lithaelese tse boima joalo ka lihitara kapa li omisa li sebetsa ntle le ho sekoa.
Lintlha tseo u ka li nahanang: A na u nahana ka kholo ea mojaro oa nako e tlang—lijaja tsa EV, lipompo tsa mocheso? Ee? Ho fetisa inverter ea hau hona joale ho ka u pholosa hore u se ke ua e khutlisa hamorao. Ho ntlafatsa ho tloha ho 7 ho isa ho 9 kW inverter ho lehae le tloaelehileng la Amerika le nang le koloi ea motlakase ho boloka hlooho-le nako ea ho theoha tseleng.
4. Panel-to-Inverter "Oversizing" (DC/AC Ratio)
Liphanele tse fetelletseng ho matla a inverter ke mokhoa o tloaelehileng, ke hore, karo-karolelano ea 1.2 DC / AC. Ka hona, mohlala, inverter ea 5 kW e khona ho sebetsana le 6 kW ea liphanele. Sena se lumella tlhahiso e ntle ka ho fetisisa e ka khonehang likhoeling tse koahetsoeng ke maru kapa hoseng ntle le ho kenya meeli ea inverter over-voltage.
Empa u se ke ua feteletsa boholo bo feteletseng (mohlala, 1.5×), ho senya matla ka lebaka la tahlehelo ea ho pata tlas'a maemo a holimo a letsatsi.
5. Netefatsa Melao ea Tšebeliso ea Lehae le Grid
Sydney, melao ea metering ea marang-rang e fokotsa boholo ba inverter e amanang le matla a phanele; ho pota 110% ke ntho e tloaelehileng. Kotsi e fetelletseng - e ntle bakeng sa litlhophiso tsa ho itšebetsa, empa e qhekella moo litefiso tsa lijo-thollo li theohang menyakong e meng.
6. Utloisisa Mofuta oa Inverter le Tlhaloso
- Li-inverters tsa likhoele:Theko e tlaase; boholo ba 3-15
- Li-inverters tsa Hybrid:Laola phanele le ho kenya betri; e loketseng bakeng sa ts'ebetso ea bekapo.
- Li-Microinverters / Power optimizers:E ntle moo ho nang le moriti empa ho bitsa chelete e ngata ka watt.
Ho kengoa mokete oa Norfolk, UK, ho sebelisitse li-inverters tse nyalisitsoeng tsa boholo ba 9 kW ho laola ho tjhaja ha letsatsi le betri - ho emisa ho romelloa kantle ho grid nakong ea lihora tsa litheko tsa lehae tsa tlhokeho ea khabone.
7. Mohlala oa Palo ea Bophelo ba Sebele
Phoenix, Arizona, moreki oa bolulo o batla tšebeliso ea letsatsi le letsatsi ea 30 kWh hammoho le ho tjhaja EV (~7 kW tlhoro). Ba khetha:
- Phanele ea matla: 9 kW
- Inverter: 7 kW hybrid unit ho tsamaisana le tlhoko e phahameng
- Karo-karolelano ea DC/AC ~ 1.3, moloko o tsamaellanang oa hoseng/mantsiboea ntle le phepelo e phahameng ea inverter
Sistimi ena e hlahisa ~ 14,000 kWh selemo le selemo mme e ntlafatsa tšebeliso ea hau, bakeng sa phaello e phahameng ka ho fetisisa matsete.
8. Lintho Tsa ho Qetela Pele U Reka
- Katoloso e tlang:A na u tla kenya liphanele kapa libeteri? Khetha inverter ho lumella sena.
- Tlhokomelo le tiisetso:Li-inverters tse bohlale li lumella tlhahlobo e hole.
- Lintlha tse sebetsang hantle:Sheba li-curve tse sebetsang hantle, eseng metsi a tloaelehileng.
