Learn what causes generator harmonic distortion, how it affects equipment, what to measure, and which remedies fit different power-quality problems.
Generator Troubleshooting
Find helpful blog articles that guide you through diagnosing and resolving common generator issues. From startup failures and voltage drops to fuel delivery problems and error codes, these posts provide step-by-step troubleshooting tips for both diesel and portable generators. Whether you’re a homeowner or technician, our content offers practical solutions to keep your generator running reliably.
Generator and Inverter Compatibility: Harmonics, Voltage Distortion and Why Some Inverters Work Better With Generators
Why some inverter-chargers distort generator voltage, why a larger generator can appear to fix the problem, what Eaton, Cummins, STAMFORD, Caterpillar, ABB, Schneider Electric and Leroy-Somer say, and how generator-aware inverter design such as Victron can improve compatibility.
Generator Exhaust Backpressure: Why Pipe Size, Bends, and Silencers Matter
Learn why diesel generator exhaust pipe size, bends, silencers, routing, supports, and commissioning measurements all affect backpressure and reliable operation.
Diesel Generator Coolant Testing: Freeze Protection, Additives, and Replacement Decisions
Coolant colour and reservoir level do not prove that a diesel generator is protected. Learn how to verify coolant type, freeze protection, inhibitors, contamination, and cooling-system condition without mixing incompatible chemistries.
When Does a Generator Need Load-Bank Testing?
Learn when generator load-bank testing is useful for commissioning, periodic readiness checks, lightly loaded diesel sets, troubleshooting, and post-repair verification.
Generator Starting Battery Test: Why Resting Voltage Is Not Enough
Learn why resting voltage alone cannot prove a generator battery can crank the engine, and how load, cranking, cable-drop, and charging checks improve diagnosis.
Generator Cooldown and Shutdown Delays: Protecting Turbo-Diesel Engines
Learn when a diesel generator needs a cooldown delay, how controllers remove load before shutdown, and what to verify for turbo and remote systems.
Generator Overload When Charging Batteries: Inverter-Charger Settings, Power Factor, and Proper Sizing
Learn why a generator overloads while charging batteries, how inverter-charger settings and power factor affect sizing, and how to select a diesel generator for reliable off-grid charging.
