-SW = No Transmitter

Ordering guidelines: Determine the basic model and add your desired features as described from bove.
Ex: Solis-50K-US-F-LSW-SPRT, (inverter with Fan andinternal Sunspec transmitter)

(50-66)kW three phase series string inverter are suitable for commercial and light industrial PV plants. These units have a compact and light design making them a two-person easy installation. The ultra-low THDi of ˂2% and filter features add multiple layers of protection for the grid and can have up to 6MW in parallel. For easy installation and O&M, these units have a separable wiring box allowing the EPC to install the wiring box ahead of time and add the inverter at a later time. To finish it off these units have multiple options of communication and protocols with free APP and PC monitoring.
