The SSTART-12-20A SureStart Soft Starter is an advanced single-phase soft start module designed to dramatically reduce compressor in-rush current for 115V HVAC and motor-driven systems. Purpose-built for scroll, rotary, and reciprocating compressors, SureStart technology delivers smoother starts, reduced electrical stress, and improved reliability—especially in generator, inverter, and solar-powered applications.
60–70% In-Rush Current Reduction
Significantly lowers locked-rotor amps (LRA), minimizing light flicker, nuisance breaker trips, and voltage sag.
Intelligent Auto-Tuning Start Algorithm
Self-learning software optimizes every start based on motor load and power quality—no manual adjustment required.
Motor & System Protection
Built-in safeguards for low voltage, over-current, motor reversal, and failed start conditions.
Generator & Off-Grid Friendly
Reduces generator and inverter surge requirements, enabling smaller, more cost-effective power systems.
Out-of-Circuit After Startup
Consumes less than 2W during normal operation, ensuring high efficiency once the motor is running.
Residential HVAC Systems
Ideal for 115V air conditioners and heat pumps using PSC motors.
Solar, Inverter & Generator Systems
Enables reliable motor starting on limited or unstable power sources.
RV, Marine & Mobile Power
Reduces startup shock and power demand in mobile environments.
Backup Power Installations
Improves compatibility between HVAC equipment and standby generators.
115V single-phase scroll, rotary, and reciprocating compressors
Permanent Split Capacitor (PSC) motors
Note: Not compatible with inverter-driven compressors or digital scroll compressors. Remove hard-start kits before installation.
