Morningstar > SureSine 1250 Watt 48VDC 120VAC Pure Sine Wave Inverter with Hard-Wired AC Output, 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.
