Pro Tips
Inductive motors (AC, pumps, compressors) need 3–7× running watts at startup. Use the right factor for accurate sizing.

Load Distribution Analysis
Total power at steady-state, converted to kVA (÷ PF 0.8) to match the genset rating.
Inrush current surge when a motor or compressor first starts — can be 3–7× normal power.
A pure 20% margin above the peak load (surge), per NEC & PUIL 2011 — not part of the Remaining Capacity above.
NEC (National Electrical Code) — a US electrical standard, adopted globally as the reference for genset sizing & load protection.
PUIL 2011 (General Requirements for Electrical Installations) — Indonesia's national standard governing electrical installations, including backup genset systems.
Power Parameters
* NEC & PUIL 2011 standards. kVA = kW ÷ 0.8 (diesel genset power factor).

Open vs Silent vs Container: Which One Is Right for You?
Silent types keep noise below <75 dB but cost 30–40% more. Containers are ideal for remote sites. Choose based on environmental regulations, budget, and mobility needs.

Standby gensets are rated for emergency use, max 200 hours/year. Running one as prime power continuously risks premature failure within 6–12 months. Choose the rating that matches your usage pattern.

AMF detects a PLN outage and starts the genset on its own. ATS needs an external signal. For hospitals, data centers, and critical sites — the wrong choice means downtime exactly when it matters most.
