How Generac Generators Perform in Cold Weather

Do you crave reliable home power during harsh winter conditions? All standby generators face challenges when starting and operating in freezing temperatures, but Generac generators are designed to perform exceptionally well. They are also compatible with various accessories to improve cold weather durability. Here are the add-ons and maintenance steps the manufacturer recommends to help keep the power on when the wind blows and the temperature plummets:

• Engine block heaters: These heaters maintain the engine coolant temperature, ensuring quick and reliable starts even in freezing weather. They typically require one to two hours to bring the engine to the optimal starting temperature.
• Battery heaters: Battery heater pads and blankets keep batteries warm, maintaining their power levels. A fully charged battery at 80 degrees F will have about 40 percent available power at 0 degrees F, making these heaters crucial for reliable starts.
• Automatic disconnects: Engine block heaters and battery heaters are designed to automatically disconnect during the start sequence, preventing potential damage. This ensures the generator operates smoothly without manual intervention.
• Automatic battery chargers: Keep the battery fully charged with automatic chargers to ensure it has sufficient starting power. This is vital for the extreme cold reliability of Generac generators.
• Protective enclosures: All generators require adequate ventilation for combustion and cooling. If significant ice and snow are expected in the installation area, the generator should be installed inside an enclosure. This protects it from the elements, while inlet and exhaust vents allow for sufficient airflow. When blowing snow and ice is anticipated, motorized louvers should be installed to seal the vents when the generator is not in use, keeping it ready for operation.
• Proper coolant mixtures: Using the recommended engine coolant mixture prevents freezing and ensures smooth operation. Consult your dealer to determine the optimal mixture.
• Winter-grade diesel fuel: Use winter-grade fuel instead of summer fuel when the temperature demands it. This option is lighter, less oily, and less lubricating than summer fuel.
• Fuel additives: Anti-gelling additives prevent wax buildup and filter blockages that hinder the generator’s operation. This ensures a continuous fuel supply to the engine, even in extreme cold​​​​.
• Regular maintenance: Regularly checking on the air filter, spark plugs, and battery charge are essential to keep your generator running all winter. The manufacturer also recommends keeping the generator free from debris and ensuring at least 3 feet of clearance on all sides to maintain optimal performance.
