The most common cause is the battery. First, ensure the unit is in "AUTO" or "STANDBY" mode and check that the battery connections are tight and corrosion-free. Batteries older than two years should be considered for replacement. Also, verify fuel levels and ensure the fuel shutoff valve is in the "ON" position. If these steps don't resolve the issue, it is time to call a professional.

The first thing to check is the generator's main circuit breaker. If it has tripped, you can try resetting it. Also, inspect the automatic transfer switch to ensure it is functioning correctly. Persistent issues may point to a problem with the voltage regulator or internal wiring, which requires expert service.

For most commercial applications, we recommend bi-annual service to ensure year-round reliability. This typically includes one major service (involving fluid and filter changes) and one minor service (focused on inspection and testing) per year.

This regular schedule for commercial generator maintenance is the best way to extend the life of your equipment.

While business owners can perform basic monthly visual checks, like looking for leaks and ensuring the area around the generator is clear of debris, all significant maintenance and repairs should be handled by a factory-trained, certified technician.

Professionals can spot developing problems, perform warranty repairs correctly, and ensure your system is fully compliant and ready for an outage.
