How Soft Starts Work and Why They Matter
Soft starts are sophisticated electronic devices designed to manage the initial power surge when an RV air conditioner (AC) compressor kicks on. Without a soft start, the AC compressor draws a significant amount of electrical current instantaneously. This sudden demand can overwhelm the electrical system of an RV, particularly those with limited power sources like shore power, generators, or even smaller battery banks. The soft start mitigates this by gradually increasing the voltage supplied to the compressor motor. This controlled ramp-up reduces the initial current draw, preventing voltage drops and protecting sensitive electrical components from premature wear and tear.
The mechanism behind a soft start typically involves a series of electronic components, often including capacitors and resistors, that work in sequence to regulate the power delivery. As the AC unit receives the signal to turn on, the soft start doesn’t immediately apply full power. Instead, it slowly feeds voltage to the compressor motor, allowing it to spin up to speed more gently. This process is crucial for extending the lifespan of the AC unit’s motor and compressor, as it minimizes the mechanical stress associated with sudden starts.
Beyond protecting the AC unit itself, a soft start offers significant benefits to the overall electrical health of your RV. By reducing the peak current draw, it prevents flickering lights, the tripping of circuit breakers, and the strain on your generator or inverter. This is especially important for RVers who rely on portable generators or are connected to lower amperage shore power hookups, where an uncontrolled startup surge could easily lead to power interruptions.
