115V Version

220V Version

The SureSine is a pure sine wave inverter delivering AC power in off-grid solar applications, including rural electrification, telecom, remote homes, RVs, caravans and boats. A cast, anodized aluminum enclosure with no internal cooling fan needed ensures long-term reliability in the harshest conditions. The SureSine’s combination of performance, features and competitive price provides the best small inverter value on the market. It is highly reliable, having no internal cooling fan or other moving parts prone to failure.

How to Buy

Key features and benefits

• Improved Load Operation
  • Pure Sine Wave – provides quality AC equivalent to grid power.
  Toroidal transformer design generates good wave form throughout the range of input voltages. 600W peak/surge power.
  • Outstanding Surge Capability – handles a 200% surge during
  load start-up, to a maximum of 600W.
• More Power Available
  • High Efficiency – a high peak efficiency will reduce heating and
  make more solar energy available for powering loads.
  • Low Self-Consumption – The SureSine consumes only 450mA of
  current during operation with a full sine-wave present at the AC
  output. During periods where no load is detected, solar energy
  is not wasted because the SureSine automatically powers down
  to standby mode, reducing self-consumption to one-tenth of
  operating consumption.
• Extremely High Reliability
  • Extensive Electronic Protections – the SureSine has
  extensive electronic protections that will automatically protect
  against faults and user mistakes such as short circuit, overload,
  high temperature and low voltage disconnect. Recovery from
  most faults is automatic.
  • No Internal Cooling Fan – a key design objective since fans often
  fail in harsh environments and are noisy, consume power and
  blow dirt into the electronics.
  • Tropicalization – the SureSine uses epoxy encapsulation,
  conformal coating, stainless steel hardware, and an anodized
  aluminum enclosure to protect against harsh tropical and marine
  environments.
• Other Features
  • More Information – the two LEDs provide important information
  to the user about system status and any fault conditions. An
  optional digital meter may be connected to the SureSine to
  display additional system information.
  • Remote On/Off – improves safety by making it easy to install
  the SureSine in an inaccessible location or enclosure. Reduces
  system cost by avoiding the need to add an AC safety disconnect
  to the system.
  • Adjustability & Communications – four DIP switches provide
  easy adjustability of several system parameters. Additional
  adjustability is possible using Morningstar’s USB MeterBus
  Adapter (UMC-1) to connect to a PC. Free 3rd-party MODBUS
  software is available for custom programming. IP-based
  communication, including SNMP, is enabled through
  Morningstar’s Ethernet MeterBus Converter (EMC-1).
