Pre-Operation & Inspection:1. Read Manual: Thoroughly read and understand the operator's manual.2. Visual Inspection: Check for any shipping damage, loose parts, or fluid leaks.3. Fluid Levels: Add and Confirm all fluids are at the correct level (engine oil, coolant if liquid-cooled, fuel).4. Batter Read More

For Undervoltage:1. Low Engine Speed (RPM): The most common cause. Engine not running at rated speed.2. Faulty AVR (Automatic Voltage Regulator): AVR is failing to supply sufficient excitation current.3. Overloading: Connected load exceeds the generator's capacity.4. Poor Connections: Loose or corro Read More

1. Faulty AVR (Automatic Voltage Regulator): The AVR fails to supply or control the DC current needed to create the rotor's magnetic field.2. Brush/Wearing Issues (if applicable): Worn-out, stuck, or dirty brushes prevent excitation current from reaching the rotor.3. Failed Rotating Diodes (if appli Read More

Principle Difference· Excitation Generator: The rotor creates its magnetic field using an external electrical current (excitation). An Automatic Voltage Regulator (AVR) supplies and controls this current to maintain a stable output voltage.· PM Inverter Generator: The rotor uses powerful permanent m Read More

Step-by-Step Selection Guide1. List & Categorize All Loads· Resistive Loads: Convert energy directly to heat/light (e.g., incandescent lights, heaters, kettles). Running Watts = Rated Watts.· Inductive Loads: Contain electric motors (e.g., pumps, compressors, power tools). Require a high startup sur Read More

Using a small air-cooled diesel generator set to forcibly start a high-power inductive load that exceeds its carrying capacity (such as a large motor, air compressor, etc.) is very likely to cause the generator to burn out. The following are three major risks: 1. Stator winding overheating When the Read More
