Mefuta ea li-Solar Inverters
Li-Inverters tse Kenyellelitsoeng Grid:
Ts'ebetso: Li-inverters tsena li hokahanya motlakase oa AC oo li o hlahisang le motlakase oa AC oa grid ea utility. Ke mofuta o atileng haholo oa li-inverter tsa letsatsi tse sebelisoang lits'ebetsong tsa bolulo le tsa khoebo.
Melemo: Li-inverters tse nang le marang-rang li lumella metering ea marang-rang, moo motlakase o feteletseng o hlahisoang ke lisebelisoa tsa letsatsi o ka khutlisetsoang ka har'a marang-rang, hangata o fella ka likoloto kapa likoloto tsa motlakase tse fokotsehileng.
Li-Inverters tsa Off-Grid:
Mosebetsi: E etselitsoe litsamaiso tse ikemetseng tse sa hokahaneng le grid ea utility. Ka tloaelo li kenyelletsa polokelo ea betri ho boloka motlakase o mongata o hlahisoang mots'ehare bakeng sa ho sebelisoa bosiu kapa linakong tsa letsatsi le tlase.

Li-Inverters tsa Hybrid (Battery Backup):
Ts'ebetso: Li-inverters tsena li kopanya likarolo tsa li-inverters tse tlamelletsoeng ke grid le li-off-grid. Li ka sebetsa ka bobeli le ntle le khokahanyo ea grid, tse kenyelletsang polokelo ea betri ho eketsa tšebeliso ea matla a letsatsi.

Ts'ebetso le likarolo
Phetoho ea DC ho AC: Li-Solar inverters li fetolela motlakase oa DC o hlahisoang ke liphanele tsa letsatsi hore e be motlakase oa AC ka ts'ebetso e kenyelletsang lisebelisoa tsa ho fetola semiconductor tse kang insulated gate bipolar transistors (IGBTs).
Maximum Power Point Tracking (MPPT): Li-inverters tse ngata li kenyelletsa theknoloji ea MPPT, e ntlafatsang tlhahiso ea solar panel ka ho tsoela pele ho fetola motlakase oa ho sebetsa le oa hona joale ho netefatsa hore ho ntšoa matla a mangata tlas'a maemo a sa tšoaneng a letsatsi.
Tlhokomelo le Taolo: Li-inverters tsa sejoale-joale hangata li tla le lits'ebetso tsa ho beha leihlo tse fanang ka data ea nako ea nnete mabapi le tlhahiso ea matla, boemo ba sistimi le metrics ea ts'ebetso. Litsamaiso tsena li lumella basebelisi ho lekola tlhahiso ea matla, ho tseba mathata a ka bang teng, le ho ntlafatsa ts'ebetso ea sistimi.

Katleho: Li-inverters tsa letsatsi li sebetsa ka maemo a phahameng a ts'ebetso, hangata ho tloha ho 95% ho isa ho 98%. Ts'ebetso ena e netefatsa tahlehelo e fokolang ea matla nakong ea ts'ebetso ea phetoho ea DC ho ea ho AC, e leng ho eketsang kakaretso ea tlhahiso ea matla ea tsamaiso ea letsatsi ea PV.
