Inverter langai hpe garan gachyan ai gaw, jak rung ni hpe bai gram lajang ai lam hpe shayawm ya lu ai, raitim, bungli masing yawng a manu hta DC/DC galai shai ai, makawp maga ai, hkang ai, bungli galaw hpang ai, htawm hpang hta gram lajang ai manu ni mung lawm ai. Shawng nnan na arung arai jahpan yawm ai gaw hpang de grau ngang kang ai bungli galaw ai (sh) jat wa ai shadawn sharam ni hpe shabyin ya lu ai.
"AC Coupling gaw Ya nga ai Solar Project ni a matu sha re"
AC coupling gaw retrofit ni hta law law lang lang lang ai raitim, n-gun n rawng ai grid charge, shanglawt ai hku shagun dat ai, shing nrai modular jat wa ai bungli masing nnan ni hpe mung galaw ya lu ai. Project stage gaw law law hta na langai mi re-dai gaw nta gawgap ai lam hpe sha dawdan ai n re.
Ndai shingdaw ai lam gaw, nta gawgap ai lam lahkawng hpe mung, akyu langai kaw nna n lata ging ai hpe madun nga ai.
AC coupling gaw, n-gun grau ja ai hte modularity hpe jaw ya ai. DC coupling gaw PV-to-battery lam hpe kadun shangun nna, clipped energy (sh) garan gachyan ai shada da matut mahkai ai atsam hpe grau kaja hkra jai lang lu ai.
Tengman ai lata la ai lam gaw, bungli masing a hkrang sumla ting kaw na pru wa ai: npawt nhpang, n-gun atsam lam, bungli galaw ra ai lam ni, grid matut mahkai lam, jat wa na masing. Ndai lam manga hpe rau jawm jep joi yu nna, nta gawgap ai lam hpe n jahtum shi yang galaw ra ai.
Solar + Hka htung masing hpe masing jahkrat nga ai kun?
Na a project ra kadawn ai lam ni hpe garan gachyan ya u.Polinovel ahpaji hpung kaw nna.
