Prepare an ATS-ready silent diesel generator RFQ with load, voltage, transfer switch, noise, enclosure, fuel tank, and control details.
What buyers should know first
An ATS-ready silent diesel generator is not only a generator with a quiet canopy. The generator controller, battery charger, start signal, circuit breaker, transfer switch rating, cable route, and site load all need to work together. If these details are missing, the quotation may look attractive but still leave gaps during installation.
For backup projects, Yangzhou Tesla Power Equipment Co., Ltd. needs to know the load kW/kVA, utility voltage, generator voltage, phase, frequency, expected noise limit, and whether the ATS will be supplied with the generator set or by the electrical contractor.
Quotation details that should be aligned
| Area | What to confirm | Common mistake |
|---|---|---|
| ATS capacity | Ampere rating, voltage, poles, and enclosure. | Quoting generator kVA but omitting ATS amperage. |
| Controller interface | Auto-start signal, alarm contacts, battery charger. | Assuming any ATS can start any controller. |
| Silent canopy | Noise target, airflow, exhaust direction, service doors. | Choosing only by price without site noise limits. |
| Load type | Motors, UPS, compressors, pumps, or mixed loads. | Ignoring starting current and voltage dip. |
| Fuel autonomy | Tank capacity and expected runtime at load. | Comparing tank size without load assumption. |
In practice
A hospital, factory, data center, apartment complex, and farm may all ask for an ATS-ready generator, but the correct configuration can be different. Some projects need fast automatic transfer. Others need delayed start, warm-up time, cool-down time, or manual test mode. Sensitive loads may need closer attention to voltage and frequency stability.
Noise also depends on installation. Walls, nearby buildings, exhaust discharge, air inlet direction, and load level can change site perception. The RFQ should state whether the sound requirement is measured at a specific distance and load condition.
Before requesting a quotation
- Send the load list and required generator output in kW and kVA.
- Confirm voltage, phase, frequency, and earthing arrangement.
- State whether ATS is included and where it will be installed.
- Request controller, breaker, charger, and wiring-diagram details.
- State noise expectation, enclosure preference, and access constraints.
Internal references worth checking
Review automatic transfer switch operation together with the silent diesel generator noise guide. A related product example is the 30kW to 60kW soundproof Cummins diesel generator set with ATS option.
Common questions before quotation
Does ATS mean the generator starts automatically?
The ATS usually sends the start signal, but the generator controller, battery system, charger, and wiring must be configured for automatic operation.
Can the ATS be purchased separately?
Yes, but the generator supplier and electrical contractor should align voltage, amperage, pole arrangement, controller signals, and wiring drawings.
Is a silent generator completely silent?
No. A silent or soundproof canopy reduces noise, but engine exhaust, airflow, installation layout, and load still affect the final sound level.
What should be checked for indoor installation?
Confirm ventilation, exhaust routing, fuel system, access, noise treatment, fire requirements, and local electrical rules with the project engineer.
Should standby or prime rating be used?
For emergency utility backup, standby rating is often relevant. For long daily operation, prime duty should be discussed.
