-LSW-SPRT = Sunspec Transmitter
-LSW-RSS = Tigo transmitter
-SW = No Transmitter

(25-40)k three phase series string inverters adopt a 4 MPPT design to provide a more flexible configuration scheme with a smaller environmental impact rate and higher generation efficiency. These NEMA 4X inverters come standard with a separable wiring box which allows a shorter install time and easy operation and maintenance.
