Morningstar Professional/SureSine 300 48 V Pure Sine Wave Inverter with North America Type B Receptacle

Since 1993 the name Morningstar has been synonymous with industry-leading charge controllers, used in mission-critical applications around the world. With that heritage and reputation, "Morningstar of Inverters" has a very high bar to meet. The new SureSine line was conceived for exactly that reason: meeting customer requests for a Morningstar inverter that's equal to the quality and performance of our charge controllers. These new models are more than up to that task. The new SureSine off-grid inverter line is comprised of six new models from 150W-2,500W with 120V/60Hz or 230V/50Hz output and 12, 24 or 48V DC input options to cover a wide range of off-grid applications requiring a high-performance, industrial-grade, pure sine wave inverter. They greatly expand our inverter offering that started with the acclaimed SureSine Classic. SureSine line uses industrial-grade build quality throughout, with models built around premium toroidal transformers for improved sinewave stability. Designed for the most demanding off-grid mission-critical installations. Superior thermal performance with fanless design means higher reliability- for example, the 300W model doesn't derate until 45 C and delivers 200W at 60 C. The small 150W model doesn't derate even at 60 C! That's outstanding performance in their power classes. Full communications capabilities include: RS485, USB, Ethernet, MS-CAN, Bluetooth while using industry-standard MODBUS protocol.
