3. ECO-THROTTLE (ELECTRICAL GOVERNOR)
Operating Principles
• Variable Engine Speed
The inverter’s CPU compares the current output voltage, current and engine speed with what is programed it its
memory and sets the throttle position accordingly. The actual required engine speed then is based on generator load
ratio and temperature. As a load is applied, the engine speed, generator output power will drop momentarily. The
inverter will calculate the type of load (how much of power drop is occurring) and set the engine speed accordingly.
• Engine Stall Prevention System
Detecting the engine load by the throttle opening the system prevents engine speed from going down when the load is
excessively high, beyond engine load capacity by controlling the output voltage at the inverter. This system is able to
generate maximum power more efficiently, and control peak performance for applications that require more electric
power, such as motors. The system automatically activates higher engine speeds in order to compensate for the power
loss of the engine when used in the high altitude or deterioration if the generator caused over time.
