Hudu, abubuwan inverter nasa

1.inverter aiki yadda ya dace da rayuwa

Idan muka yi inverter aiki a babban iko na dogon lokaci, za a rage rayuwar mai inverter.Binciken ya nuna cewa rayuwar inverter da ke aiki a 80% ~ 100% iko an rage ta 20% fiye da cewa a 40% ~ 60% na dogon lokaci.Saboda tsarin zai yi zafi sosai lokacin aiki a babban iko na dogon lokaci, tsarin zafin jiki na aiki yana da yawa, wanda ke shafar rayuwar sabis.

2,mafi kyawun aikin ƙarfin lantarki na inverter

Inverter aiki ƙarfin lantarki a rated irin ƙarfin lantarki, mafi girma yadda ya dace, guda-lokaci 220V inverter, inverter rated irin ƙarfin lantarki 360V, uku-lokaci 380V inverter, shigar da rated irin ƙarfin lantarki 650V.Irin su 3 kw photovoltaic inverter, tare da ikon 260W, ƙarfin aiki na 30.5V 12 tubalan shine mafi dacewa;Kuma 30 kW inverter, rarraba wutar lantarki don sassan 260W 126 guda, sannan kowace hanya 21 kirtani shine mafi dacewa.

3. Obalodi iya aiki na inverter

Inverters masu kyau gabaɗaya suna da ƙarfin juyewa, kuma wasu kamfanoni ba su da ƙarfin lodi.Mai jujjuyawar da ke da ƙarfin ɗaukar nauyi mai ƙarfi na iya ɗaukar matsakaicin matsakaicin ƙarfin fitarwa sau 1.1 ~ 1.2, ana iya sanye shi da ƙarin kayan aikin 20% fiye da inverter ba tare da iyawa ba.

Inverter na Photovoltaic da module ba bazuwar ba ne kuma don, don zama haɗin kai mai ma'ana, don guje wa asara.Lokacin shigar da tashoshin wutar lantarki na photovoltaic, dole ne mu yi la'akari da dalilai daban-daban gabaɗaya, kuma mu zaɓi kamfanoni na photovoltaic tare da kyawawan cancantar shigarwa.
