Parallel Systems Maintenance, Diagnostics & Upgrades
Parallel systems maintenance keeps multiple generators synchronized so they share load correctly and switch over without dropping power. Hedgehog Power Systems inspects, diagnoses, and upgrades paralleling switchgear and controls for commercial and industrial sites running two or more generators together.
What's included.
- Synchronization and load-sharing diagnostics
- Paralleling switchgear inspection
- Control logic and firmware upgrades
- Load bank verification of paralleled output
- Documented findings and upgrade recommendations
How often does NFPA 110 require a generator to be tested?
NFPA 110 calls for a weekly inspection, a monthly exercise run of at least 30 continuous minutes at 30% or more of nameplate kW (or the manufacturer’s minimum exhaust gas temperature), monthly operation of each transfer switch, annual fuel quality testing, and, for Level 1 systems, a 4-hour run at least once every 36 months. The edition that applies is the one adopted by your local authority having jurisdiction, so confirm it with your AHJ.
How often should my generator be serviced?
Generators typically need full service annually or every 200 to 500 hours of operation, whichever comes first. We also recommend weekly visual checks and monthly exercise runs. A tailored plan can include breaker testing, fuel tank cleaning, and engine maintenance to prevent issues before they start.
What does a typical generator maintenance visit include?
A standard visit covers fluid checks (oil, coolant, fuel), filter inspections and replacements, battery testing, visual inspection for leaks or wear, control panel inspection, and system performance verification. Every visit ends with a written record of what was found and what was done.
