Comprehensive maintenance plans to maximize backup reliability and system lifespan
Periodic inspection of inverter PCBs, cooling fans, and charging parameters for optimum performance.
Terminal cleaning, specific gravity check (lead-acid), voltage analysis & load testing for longevity.
Detailed service reports after each visit including backup time analysis & recommendations.
Priority support for critical failures; parts and consumables charged as per actuals.
Preventive maintenance visits (Quarterly / Half-yearly): Full inspection of inverter system – IGBTs, MOSFETs, capacitor health check, cooling fan cleaning, and relay testing. Battery bank terminal cleaning, anti-corrosion application, electrolyte level top-up (for tubular batteries), and specific gravity measurement. Load testing on inverter mode to verify backup duration as per designed capacity. UPS/inverter calibration and output voltage verification. Comprehensive system health report with actionable insights.
Performance evaluation: Charger voltage analysis (boost/float mode), battery charging current verification, ripple voltage measurement. Detection of weak cells, early sulfation signs, and recommendations for replacement. Full system efficiency check and transfer time validation.
Expert guidance: Recommendations for optimal battery usage, load management, ventilation requirements, and safety protocols. Advice on extending battery life and avoiding deep discharge scenarios.
Spare parts & consumables: PCB replacement, fans, relays, switches, connectors, fuses, distilled water, terminal connectors are billed extra. Batteries (SMF, tubular, lithium) are not included in AMC cost – any battery replacement is chargeable. Breakdown repairs due to external factors like lightning, rodent damage, or mishandling are not part of standard coverage. This plan focuses on scheduled maintenance and general wear-and-tear servicing only.
Ideal for homes, small offices, retail shops, clinics, educational institutes, and small commercial setups that have 1–10 kVA inverter systems. Suitable for customers who want professional periodic maintenance without paying for full comprehensive cover. Best for tubular lead-acid and SMF battery installations where preventive care significantly enhances backup reliability and lifespan.
