Why Proactive Generator Maintenance Matters
Standby generators often remain inactive for long periods. Without regular servicing, hidden faults may only become apparent during a mains failure – and that’s when reliable backup power is most critical.
Proactive generator maintenance helps reduce the risk of:
- Generator startup failure
- Fuel contamination
- Wet stacking
- Battery faults
- Mechanical wear
- Reduced performance under load.
We recommend:
- Monthly on-load testing - verify performance under real conditions.
- Comprehensive maintenance inspections every 6 months - maintain reliability and protect your generator's long-term health
- Limit off-load running.
