1. N’chifukwa chiyani mtengo wanu uli wapamwamba kuposa ogulitsa ena?

Mumsika waku China, mafakitale ambiri amagulitsa ma inverter otsika mtengo omwe amapangidwa ndi malo ogwirira ntchito ang'onoang'ono opanda chilolezo. Mafakitale amenewa amachepetsa ndalama pogwiritsa ntchito zida zosavomerezeka. Izi zimapangitsa kuti pakhale zoopsa zazikulu zachitetezo.

SOLARWAY ndi kampani yaukadaulo yomwe imagwira ntchito yofufuza ndi kukonza zinthu, kupanga, ndi kugulitsa ma inverter amphamvu. Takhala tikugwira ntchito mwakhama pamsika waku Germany kwa zaka zoposa 10, kutumiza ma inverter amphamvu pafupifupi 50,000 mpaka 100,000 chaka chilichonse ku Germany ndi misika yoyandikana nayo. Ubwino wa malonda athu ndi woyenera kudalirika kwanu!

2. Kodi ma inverter anu amphamvu ali ndi magulu angati malinga ndi mawonekedwe a mafunde otuluka?

Mtundu 1: Ma inverter athu a NM ndi NS omwe ali ndi Modified Sine Wave amagwiritsa ntchito PWM （Pulse Width Modulation） kuti apange mafunde a sine osinthidwa. Chifukwa cha kugwiritsa ntchito ma circuits anzeru, odzipereka komanso ma transistors amphamvu kwambiri, ma inverter awa amachepetsa kwambiri kutayika kwa mphamvu ndikuwongolera ntchito yoyambira bwino, ndikutsimikizira kudalirika kwakukulu. Ngakhale mtundu uwu wa inverter wamagetsi ukhoza kukwaniritsa zosowa za zida zambiri zamagetsi pamene mphamvu yamagetsi siivuta kwambiri, umakumanabe ndi kusokonekera kwa harmonic pafupifupi 20% ikagwiritsa ntchito zida zapamwamba. Inverter yamagetsi imathanso kuyambitsa kusokoneza kwa pafupipafupi kwa zida zolumikizirana ndi wailesi. Komabe, mtundu uwu wa inverter wamagetsi ndi wogwira ntchito bwino, umapanga phokoso lotsika, umakhala ndi mtengo wocheperako, ndipo chifukwa chake ndi chinthu chodziwika bwino pamsika.

Mtundu Wachiwiri: Ma inverter athu a NP, FS, ndi NK a Pure Sine Wave amagwiritsa ntchito kapangidwe kake kolumikizana, komwe kamapereka mawonekedwe a mafunde otuluka bwino komanso okhazikika. Ndi ukadaulo wapamwamba kwambiri, ma inverter amphamvu awa ndi ang'onoang'ono ndipo ndi oyenera katundu wosiyanasiyana. Amatha kulumikizidwa ku zida zamagetsi wamba ndi katundu woyambitsa (monga mafiriji ndi ma drill amagetsi) popanda kuyambitsa kusokoneza kulikonse (monga phokoso kapena phokoso la TV). Kutulutsa kwa inverter yamphamvu ya sine wave yoyera ndi kofanana ndi mphamvu ya gridi yomwe timagwiritsa ntchito tsiku ndi tsiku—kapena kuposa pamenepo—popeza sikupanga kuipitsa kwa ma electromagnetic komwe kumakhudzana ndi mphamvu yolumikizidwa ndi gridi.

3. Kodi zipangizo zotetezera katundu ndi chiyani?

Zipangizo monga mafoni am'manja, makompyuta, ma TV a LCD, magetsi oyaka, mafani amagetsi, makanema owulutsa, makina osindikizira ang'onoang'ono, makina amagetsi a mahjong, ndi zophikira mpunga zimaonedwa kuti ndi zinthu zoteteza. Ma inverter athu osinthidwa a sine wave amatha kupatsa mphamvu zipangizozi.

4. Kodi zipangizo zoyendetsera katundu zoyambitsa ndi chiyani?

Zipangizo zoyendetsera magetsi ndi zipangizo zomwe zimadalira mphamvu zamagetsi monga ma mota, ma compressor, ma relay, nyali za fluorescent, ma stoves amagetsi, mafiriji, ma air conditioner, nyali zosunga mphamvu, ndi mapampu. Zipangizozi nthawi zambiri zimafuna mphamvu zawo zowirikiza katatu mpaka kasanu ndi kawiri panthawi yoyambira. Chifukwa chake, inverter ya pure sine wave yokha ndiyo yoyenera kuziyendetsa.

5. Kodi mungasankhe bwanji inverter yoyenera?

Ngati katundu wanu uli ndi zida zotetezera, monga mababu a magetsi, mutha kusankha chosinthira mafunde cha sine. Komabe, pa zinthu zoyambitsa ndi zopatsa mphamvu, tikukulimbikitsani kugwiritsa ntchito chosinthira mafunde cha sine. Zitsanzo za zinthu zotere zikuphatikizapo mafani, zida zolondola, ma air conditioner, mafiriji, makina a khofi, ndi makompyuta. Ngakhale chosinthira mafunde cha sine chingayambe zinthu zina zoyambitsa mphamvu, chingafupikitse nthawi yake chifukwa zinthu zoyambitsa ndi zopatsa mphamvu zimafuna mphamvu yapamwamba kuti zigwire bwino ntchito.

6. Kodi ndingasankhe bwanji kukula kwa inverter?

Mitundu yosiyanasiyana ya katundu imafuna mphamvu zosiyanasiyana. Kuti mudziwe kukula kwa inverter, muyenera kuyang'ana kuchuluka kwa mphamvu ya katundu wanu.

• Zolemetsa zoletsa: Sankhani inverter yokhala ndi mphamvu yofanana ndi katundu.
• Kulemera kwa capacitive: Sankhani inverter yokhala ndi mphamvu yochulukirapo kawiri mpaka kasanu kuposa mphamvu ya katunduyo.
• Zonyamula zoyambitsa: Sankhani inverter yokhala ndi mphamvu yochulukirapo ka 4 mpaka 7 kuposa mphamvu ya katunduyo.

7. Kodi batire ndi inverter ziyenera kulumikizidwa bwanji?

Kawirikawiri amalangizidwa kuti zingwe zolumikiza ma terminal a batri ku inverter zikhale zazifupi momwe zingathere. Pa zingwe zokhazikika, kutalika kwake sikuyenera kupitirira mamita 0.5, ndipo polarity iyenera kufanana pakati pa batri ndi inverter.

Ngati mukufuna kuwonjezera mtunda pakati pa batire ndi inverter, chonde titumizireni uthenga kuti tikuthandizeni. Tikhoza kuwerengera kukula ndi kutalika kwa chingwe choyenera.

Kumbukirani kuti kulumikizana kwa chingwe kwa nthawi yayitali kungayambitse kutayika kwa magetsi, zomwe zikutanthauza kuti magetsi a inverter akhoza kukhala otsika kwambiri kuposa magetsi a batri, zomwe zimapangitsa kuti alamu ya undervoltage igwe pa inverter.

8.Kodi mumawerengera bwanji kuchuluka kwa katundu ndi maola ogwirira ntchito ofunikira kuti mukonze kukula kwa batri?

Nthawi zambiri timagwiritsa ntchito njira iyi powerengera, ngakhale kuti sizingakhale zolondola 100% chifukwa cha zinthu monga momwe batire ilili. Mabatire akale akhoza kutayika pang'ono, kotero izi ziyenera kuonedwa ngati mtengo wofotokozera:

Maola ogwira ntchito (H) = (Kuchuluka kwa batri (AH) * Voltage ya batri (V0.8) / Mphamvu yonyamula (W)
