Solis-(25-40)K-US

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

Ordering guidelines: Determine the basic model and add your desired features as described from bove.
Ex: Solis-40K-US-F-LSW-SPRT, (inverter with Fan andinternal Sunspec transmitter)

Solis-(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.
