Solar Inverter Tring Dights Kuverenga
Chinyorwa chinotevera chichakubatsira kuverenga nhamba yepamusoro / shoma yemamendi pane series yeture kana uchigadzira yako PV system. Uye iyo yekuvhara yekukoshesa inosanganisira zvikamu zviviri, voltage, uye kurongeka kwazvino. Munguva yemukati yekukuitira iwe unofanirwa kufunga nezveimwe nzira yekugadzirisa, iyo inofanira kutariswa kana ichidurura simba renzvimbo yeiyo Uye panguva yekubata, tembiricha inokanganisa chinhu chakakosha.
1. Solar panel tembiricha coefficient yeVOC / ISC:
Iyo voltage / yazvino iyo solar panels inoshanda pane inoenderana nekushisa tembiricha, yakakwira tembiricha yakaderera Iyo voltage / yazvino yehurongwa ichagara iri pane yakakwirira kwazvo mumamiriro ezvinhu anotonhora uye semuenzaniso, iyo sosi tembiricha yekubatanidza yeVoc inodikanwa kuti ishandise izvi. NaMono uye poly crystalline solar panels inogara iri isina kunaka% / OC nhamba, yakadai se -0.33% / OC pane zuva 72P-35F. Ruzivo urwu runogona kuwanikwa pane iyo solar panel magadziri data sheet. Ndokumbira utarise kune nhamba 2.

Panzvimbo yeSolar payakashandiswa mumutambo wenhevedzo Naizvozvo isu tinofanirwa kuziva kuti vangani masosi emwenje iwe waunofunga kuti waya.
Kana iwe uine ruzivo rwese rwaunenge wagadzirira kupinda mukati meiyo inotevera solar panel voltage sings uye zvazvino kugadzirisa kuverenga kuti uone kana iyo solar panel pane inokodzera zvaunoda.
Voltage Sizing:
1. Max Panel's voltage = VOC * (1+ (min.Temp-25) * tembiricha coefficient (VOC)
2. Max nhamba yeiyo solar panels = max. Input voltage / max panel's voltage
Yazvino Kubata:
1. Min Panel's zvazvino = isc * (1+ (max.Temp-25) * tembiricha coefficient (ISC)
2. Max nhamba ye tambo = max. Input ikozvino / min panel yazvino
3. Muenzaniso:
Curitiba, guta reBrazil, Mutengi akagadzirira kuisa imwe renac simba 5Ku tembiricha iri makumi matatu neshanu inogona kumira 1000V.
Inverter uye datasheet:
Solar Panel Datasheet:
A) voltage sizing
Pakushomeka kwepasi
1) Kuverenga kweiyo yakavhurika wedunhu voltage at -3 ℃:
Voc (-3 ℃) = 45.5 * (1 + (- 3-25) * (- 0.33%)) = 49.7 volt
2) Kuverenga kweN iyo nhamba yepamusoro yemifananidzo mune imwe tambo:
N = max Input voltage (1000 v) /49.7 volt = 20.12 (nguva dzose kutenderera)
Huwandu hweSolar PV pane imwe tambo hadzina kupfuura makumi maviri emamita kunze, pakupisa kwakanyanya
3) Kuverenga kweiyo yepamusoro Simba Voltage vmpp na 35 ℃:
Vmpp (35 ℃) = 45.5 * (1+ (35-25) * (- 0.33%)) = 44 volt
4) Kuverenga kwehuwandu hushoma hwe modules m mune tambo imwe neimwe:
M = min mp mpP voltage (160 v) / 44 volt = 3.64 (nguva dzose kutenderera)
Nhamba yeiyo solar pv mapanera mune imwe neimwe tambo inofanira kunge yave kuita mana module.
B) Yazvino sizing
Iyo pfupi redunhu racho riripo i spi yePV Array haifanirwe kusapfuura iyo inobvumirwa yakakwana yekuisa mari iripo yeiyo Solar Simba Inverter:
1) Kuverenga kweiyo yakakwira ikozvino ku 35 ℃:
Isc (35 ℃) = ((1+ (10 * (TCSC / 100)) * ISC) = 9.22 * ((1 (0.06%)) = 9.16 a
2) Kuverenga kweP huwandu hwakawanda hwetambo:
P = Yakakura Input Yazvino (12.5a) /9.16 A = 1.36 tambo (nguva dzose kutenderera)
Iyo PV Array haifanirwe kusapfuudza tambo imwe.
REMAK:
Iyi nhanho haidiwe iyo inverter mppt ine tambo imwechete.
C) Mhedziso:
1. Iyo PV Jenareta (PV marongero) inetambo imwe, iyo yakabatana neyezvitatu chikamu 5kw inverter.
2. Mune tambo imwe neimwe iyo yakabatana solar panels inofanira kunge iriMukati me4-20 modules.
REMAK:
Sezvo yakanakisa mpt voltage yerudzi rwechikamu chiri kumativi matanhatu Saka zvinokurudzirwa kuverenga nhamba yeiyo solar modules maererano neakanakisa mppt voltage:
N = yakanakisa mppt voc / voc (-3 ° C) = 756V / 49.7V = 15.21
Imwechete Crystal Panel Best MPPT VOC = Best MPT Voltage X 1.2 = 630 × 1.2 = 756V
Polycrystal Panel Best MPT VOC = Best MPPT Voltage X 1.2 = 630 × 1.3 = 819V
Saka for renac matatu matatu muT3--5k-dt iyo yakakurudzirwa yekupinda Solar pane 16 module, uye ingoda kubatanidzwa tambo imwe 16x330w = 5280w.
4. Mhedziso
Inverter yekuisa hapana ye solar panels inoenderana nekushisa kwesero uye tembiricha inoenderana. Kuita kwakanaka kwakavakirwa pane yakanakisa mppl voltage yeiyo inverter.
