Morningstar > SureSine 300 Watt 12VDC 120VAC Pure Sine Wave Inverter with North America Type B Outlet, UL Approved
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 (Generation 2) SureSine line was conceived for exactly one 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.
