Lub off-grid photovoltaic inverter yog ib qho tseem ceeb ntawm lub off-grid photovoltaic fais fab chaw nres tsheb los yog fais fab mov.#dc rau ac fais fab inverters Tsis tsuas yog cov efficiency ntawm lub photovoltaic fais fab mov nws tus kheej, #inverter 24v 220v 5000w tab sis kuj cov efficiency thiab txhim khu kev qha. kev khiav hauj lwm ntawm tag nrho cov system muaj li ntawm lub hwj chim mov thiab lub load yuav tsum tau txiav txim siab.

Yuav ua li cas ntsuas qhov voltage ntawm lub inverter: Paub txog qhov ntau ntawm cov zis voltage, koj tuaj yeem siv qhov kev sojntsuam sib txawv ntxiv rau oscilloscope los kuaj, lossis koj tuaj yeem siv qhov ntsuas attenuator ntxiv rau multimeter lossis oscilloscope los kuaj. Feem ntau muab faib ua qhov kev xeem nyob rau hauv lub xeev khov kho thiab dynamic test.

1. Yuav ua li cas ntsuas qhov voltage ntawm lub inverter, dynamic test: sudden load los yog sudden load txo kev sim: thawj zaug siv lub "fais fab cuam tshuam analyzer" los ntsuas cov theem voltage thiab zaus ntawm tsis muaj load thiab khov kho, #off-grid inverter thiab ces mam li nco dheev lub load ntawm 0 mus rau 100 feem pua Los yog cia li load txo los ntawm 100 feem pua mus rau 0. Yog hais tias lub UPS tso zis voltage nyob nruab nrab ntawm -8 feem pua thiab 10 feem pua, thiab nws rov qab mus rau lub xeev ruaj khov hauv 20ms, UPS tsim nyog; Yog tias UPS cov zis hluav taws xob hloov pauv tau dhau los hauv qhov ntau, qhov loj dua tam sim no yuav raug tsim tawm, uas yog qhov tsis zoo rau cov khoom thauj lossis UPS nws tus kheej, yog li hom UPS no tsis haum rau kev xaiv.

Thov ua siab zoo saib thiab nkag siab zoo dua rau peb:

3000w 12v 120v pure sine wave inverter
