Features and General Information

  • Pure Sine Wave - Quality AC equivalent to grid power, extends the life of the household appliances (lights, TV, fans) and improves load performance.
  • Toroidal transformer design – Generates good wave form throughout the range of input voltages.
  • Outstanding Surge Capability – Handles up to a 200% surge during load start-up and a maximum of 600 watts.
  • High efficiency - High peak efficiency reduces heating and makes more solar energy available for powering loads.
  • Low Self-Consumption – The SureSine consumes 450mA while powering loads. During no load conditions, the SureSine automatically powers down to stand-by mode, conserving solar energy by reducing self-consumption to one tenth of operating consumption.
  • Extensive Electronic Protections - The SureSine protects automatically against faults and user mistakes such as short circuit, overload, high temperature and low voltage disconnect. Recovers automatically from most faults.
  • No Internal Cooling Fan design - Fans often fail in harsh environments and are noisy, consume power and blow dirt into the electronics.
  • Suitable For Tropical Regions - The SureSine protects against harsh tropical and marine environment by using epoxy encapsulation, conformal coating, stainless steel hardware, and an anodized aluminum enclosure.
  • Remote On/Off - Improves safety, easy to install the SureSine in an inaccessible location or enclosure, and reduces system cost by avoiding the need to add an AC safety disconnect to the system.
  • Adjustability - Four DIP switches for easy adjustability of several system parameters. Additional adjustability via an RJ-11 to RS-232 adapter to a personal computer using Morningstar’s PC software.
