Photovoltaic Controllers: Zvikamu Zvikuru uye Zvimiro

Chii chinonzi Photovoltaic controller?

Chinodzora magetsi chephotovoltaic chimwe chezvinhu zvakakosha mugadziriro yekugadzira magetsi ephotovoltaic. Basa rayo guru nderekutarisira nekudzora simba remagetsi rinogadzirwa nema solar panels.

Ngationgororei mashandiro emuchina we Photovoltaic controller . Unokwanisa kutarisa nekugadzirisa mashandiro ekuchaja nekuburitsa mabhatiri, zvichiita kuti agare akachengeteka uye achishanda zvakanaka. Nekushandisa simba remagetsi zvinobudirira, unogona kuwedzera hupenyu hwemabhatiri.

Iyo Photovoltaic controller ine zvakare anotevera akakosha maficha:

Energy Conversion Optimization: Inosimudzira kushanda kwe photovoltaic system, kuwedzera kushandurwa kwesimba rezuva kuita simba remagetsi rinoshandiswa.
Dziviriro yebhatiri: Inodzivirira kuwandisa uye kuburitsa zvakanyanya, kuderedza kupfeka kwebhatiri uye kutadza.
Kugadzikana: Inochengetedza kushanda kwakagadzikana kwese photovoltaic system, isingagadziriswi nekunze kwezvinhu.

Paunosarudza Photovoltaic controller, zvinotevera zvinofanirwa kutariswa:

• Sistimu chiyero uye zvinodiwa.
• Mhando yebhatiri uye huwandu.
• Controller unhu uye kuvimbika.

Iyo Photovoltaic controller chikamu chakakosha cheiyo photovoltaic simba rekugadzira system. Haingonatsiridza mashandiro ehurongwa uye kushanda zvakanaka asi zvakare inochengetedza kuchengetedzwa uye hupenyu hwemabhatiri. Kunzwisisa nheyo yekushanda uye zvikamu zveMutungamiri wePhotovoltaic zvakakosha pakusarudza kwayo uye kushandiswa kwakarurama.

Main technical parameters ye photovoltaic controller

1. System voltage

System voltage inonziwo rated operating voltage, iyo inoreva iyo DC inoshandisa voltage ye photovoltaic power generation system. Iyo voltage kazhinji ndeye 12V uye 24V. Epakati uye epamusoro-simba controllers zvakare ane 48V, 110V, 220V, nezvimwe.

2. Maximum kuchaja ikozvino

Iyo yakanyanya kuchaja ikozvino inoreva iyo yakanyanya kuburitswa ikozvino nesolar cell module kana square array. Zvinoenderana nehukuru hwesimba, yakakamurwa kuita 5A 6A 8A 10A 12A 15A 20A 30A 40A 50A 70A 100A 150A 200A 250A 300A uye zvimwe zvinotsanangurwa. Vamwe vagadziri vanoshandisa iyo yakanyanya simba re solar cell modules kuratidza izvi zvirimo, izvo zvisina kunanga zvinoratidzira tekinoroji parameter yeyakanyanya kuchaja ikozvino.

3. Nhamba ye solar cell array input channels

Yakaderera-simba photovoltaic controllers kazhinji ine imwe chete yekuisa, nepo yakakwirira-simba photovoltaic controllers ine akawanda mamepu kubva kune solar cell array. Kazhinji, high-power photovoltaic controllers
6 chiteshi inogona kuiswa, uye yakawanda inogona kubatanidzwa kune gumi nemaviri kana 12 chiteshi.

4. Denderedzwa kuzvirasikirwa

Kurasikirwa kwedunhu kwemutongi zvakare ndeimwe yeayo makuru tekinoroji paramita, inonziwo hapana-mutoro kurasikirwa (yakanyarara ikozvino) kana yakanyanya kuzvidzora-yega ikozvino. Kuti kuderedza controller wacho
Kurasikirwa, kuvandudza kushanda kwekushandura kwe photovoltaic simba rekupa, kurasikirwa kwemutongi wedunhu pachayo kunofanira kunge kwakaderera sezvinobvira. Iyo yakawanda yekurasikirwa kwega kwega kwemutongi haifaniri kudarika iyo yakatemerwa yekuchaja huwandu.
1% yekuyerera kana 0.4W. Zvichienderana nedunhu, kurasikirwa kwayo kunowanzo 5 ~ 20MA.

5. Battery overcharge protection voltage (HVD)

Battery overcharge protection voltage inonziwo full disconnection kana overvoltage shutdown voltage. Kazhinji, inogona kuiswa pakati pe14.1 ~ 14.5V (12
V system), 28.2 ~ 29V (24V system) uye 56.4 ~ 58V (48V system), maitiro akaenzana ari 14.4V, 28.8V uye 57.6V maererano. Dziviriro yekuchaja bhatiri
Iyo shutdown recovery voltage (HVR) inowanzoiswa kune imwe ye: 13.1 ~ 13.4V (12V system), 26.2 ~ 26.8V (24V system) uye 52.4 ~ 53.6V (48V system)
nguva, maitiro akajairika ari 13.2V, 26.4V uye 52.8V zvichiteerana

6. Battery over-discharge protection voltage (LVD)

Iyo over-discharge protection voltage yebhatiri inonziwo under-voltage disconnection kana under-voltage shutdown voltage. Kazhinji, inogona kuiswa pakati pe10.8 ~ 11.4V (
Pakati pe12V system), 21.6 ~ 22.8V (24V system) uye 43.2. ~ 45.6V (48V system), maitiro akajairika ndeye 11.1V, 22.2V uye 44.4V maererano. Bhatiri rakapfuura
Iyo yekuvhara kudzoreredza voltage (LVR) yekudzivirira kwekudzivirirwa inowanzoiswa ku: 12.1 ~ 12.6V (12V system), 24.2 ~ 25.2V (24V system) uye 48.4 ~ 50.4V (48V)
masisitimu), maitiro akajairika ari 12.4V, 24.8V uye 49.6V zvakateerana.

7. Battery kuchaja float voltage

Iyo yekuchaja uye inoyangarara voltage yebhatiri inowanzo 13.7V (12V system), 27.4V (24V system), uye 54.8 (48V system).

8. Tembiricha muripo

Iyo controller kazhinji ine tembiricha yekubhadhara basa kuti ienderane neyakasiyana tembiricha yekushanda kwezvakatipoteredza uye kuseta inonzwisisika yekuchaja voltage yebhatiri.
Coefficient yekubhadhara inofanirwa kusangana nezvinodiwa zvekuvandudza tekinoroji yebhatiri, uye kukosha kwayo kwemuripo wetembiricha kazhinji -20~-40mV/oC.

9. Kushanda nharaunda tembiricha

Iko kushandiswa kana kushanda nharaunda tembiricha yemhando ye controller inosiyana nemugadziri, kazhinji pakati -20~+50 oC.

10. Mamwe mabasa ekudzivirira

• Controller kupinza uye goho pfupi redunhu kudzivirira basa. Iyo yekupinza uye inobuda maseketi emutongi anofanira kunge aine mapfupi-edunhu ekudzivirira maseketi kuti ape wave kudzivirira basa
• Anti-reverse kuchaja kuchengetedza basa. Mutongi anofanira kunge ane basa rekudzivirira kudzivirira bhatiri kubva kune reverse kuchaja kune solar cell.
• Polarity reverse kudzivirira basa. Kana iyo solar cell module kana bhatiri yakabatana kune controller, mutongi anofanira kunge aine basa rekudzivirira redunhu kana polarity ichidzoserwa.
• Basa rekudzivirira mheni. Iyo yekupinza yekupedzisira yemutongi inodzivirirwa kubva pakurohwa nemheni. Rudzi uye kuyerwa kweanosunga kunofanirwa kuve nechokwadi chekutorwa kwesimba rinotarisirwa rekuita.
• Dziviriro kubva kune impulse voltage uye impulse current. Isa 1.25 nguva yezita remagetsi kune solar cell input ye controller kweawa imwe chete, controller haifanire kukuvadza. Kana iyo controller ichichaja yedunhu ikozvino inosvika 1.25 nguva yezita rezvino kweawa imwe, mutongi haafanire kukuvadzwa.

mhedziso

Muchidimbu, Photovoltaic controllers inoshanda sezvinhu zvakakosha mukati mezuva remagetsi masisitimu, kutarisa manejimendi uye kudzora kwesimba remagetsi rinobva kune solar panel. Nekugadzirisa shanduko yesimba, kuve nechokwadi chekuchengetedzwa kwebhatiri, nekuchengetedza kugadzikana kwehurongwa, vatongi ava vanobatsira mukushanda kwakanaka uye kwakavimbika kwephotovoltaic system. Nekunyatsonzwisisa kwavo kwehunyanzvi paramita uye maficha, vashandisi vanogona kuita sarudzo dzine ruzivo mukusarudza nekushandisa Photovoltaic controllers zvinobudirira.
