Ho feta moo, li-inverters tsa letsatsi li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso eatsamaiso ea matla a letsatsi. Ba na le theknoloji ea Maximum Power Point Tracking (MPPT), e ba lumellang hore ba tsoele pele ho laola motlakase le hona joale ho netefatsa hore lisebelisoa tsa letsatsi li sebetsa ka katleho e kholo.
