Ho Hybrid System, DC coupling le AC coupling ke mekhoa e 'meli ea mantlha ea meralo ea ho kopanya li-module tsa photovoltaic (PV), libeteri tsa polokelo ea matla, le meroalo kapa marang-rang. Phapang ea mantlha e mabapi le hore na motlakase o hlahisoang ke li-module tsa PV o fetisetsoa ho betri ka mokhoa o tobileng oa hona joale (DC) kapa mofuta oa alternating current (AC).
Ka tlase ke papiso e qaqileng ea mahlale a mabeli:
1. Melao-motheo ea Motheo le Phallo ea Matla
DC Coupling:
- Molao-motheo:
Motlakase oa DC o hlahisoang ke li-module tsa PV o kenngoa ho kenyelletso ea DC ea tsamaiso ea ho fetola matla (PCS) ka PV controller (DC-DC converter). Sistimi ena e kopaneng e etsa mesebetsi e latelang:
- E fetolela karolo ea matla a DC hore e be AC bakeng sa meroalo ea lehae kapa kantle ho marang-rang.
- E tjhaja betri ka kotloloho o sebelisa matla a DC (DC-to-DC).
- E ntša betri ka ho fetolela DC ho AC bakeng sa phepelo ea thepa kapa ente ea grid.
- Phallo ea Matla (Ho tjhaja):
PV Modules (DC) → Selaolo sa PV → Betri (DC)
(Tsela e tobileng ea ho tjhaja DC-to-DC)
- Phallo ea Matla (Ho Tlisa):
Betri (DC) → PCS (DC-to-AC) → Load/Gridi (AC)
- Ntlha ea bohlokoa:
Ha o tjhaja betri, motlakase o sala o le ka sebopeho sa DC nakong eohle ea ts'ebetso, o qoba liphetoho tse sa hlokahaleng.
AC Coupling:
- Molao-motheo:
Motlakase oa DC o tsoang ho li-module tsa PV o qala ho fetoleloa ho AC ka mochine o ikemetseng oa PV. Matla ana a AC a ka:
- Fana ka meroalo ea lehae ka kotloloho.
- E romelloe kantle ho marang-rang.
Ho tjhaja betri, matla a AC a tlameha ho kgutlisetswa ho DC ke PCS (betri inverter).
- Phallo ea Matla (Ho tjhaja):
PV Modules (DC) → PV Inverter (DC-to-AC) → PCS (AC-to-DC) → Battery (DC)
(E kenyelletsa mehato e 'meli ea phetoho: DC→AC→DC)
- Phallo ea Matla (Ho Tlisa):
Betri (DC) → PCS (DC-to-AC) → Load/Gridi (AC)
- Ntlha ea bohlokoa:
Ho tjhaja betri ho hloka phetoho e felletseng ea DC→AC→DC, ho hlahisa litahlehelo tse ling.

Qetello
Ka bobeli ho kopanya ha DC le AC ho fana ka melemo e ikhethang ho latela maemo a kopo. Ho kopanya ha DC ho ipabola ka katleho le ho baballa litšenyehelo bakeng sa lits'ebetso tse ncha, ho etsa hore e be sebaka se loketseng merero ea greenfield e shebaneng le ts'ebetso. AC coupling, ka lehlakoreng le leng, e fana ka phetoho e kholoanyane le ho lumellana ha morao, ho e etsa khetho e ratoang bakeng sa ho eketsa polokelo ho litsamaiso tse teng tsa PV.
Khetho e nepahetseng e ipapisitse le lintlha tse fapaneng tse ikhethileng tsa projeke - joalo ka hore na sistimi e ncha kapa e khutlisetsoa morao, likhaello tsa tekanyetso, lipehelo tsa ts'ebetso, merero ea katoloso ea nako e tlang, le lintlha tsa polokeho. Ha theknoloji e ntse e hatela pele, meralo ka bobeli e ntse e tsoela pele ho fetoha: li-inverters tsa hybrid tsa DC li fetoha tse ngata le tse matla, ha litsamaiso tse kopaneng tsa AC li ntse li ntlafala mabapi le taolo ea khokahano le katleho ea phetoho.
