Is this the right output for your needs?

Separate essential equipment from loads that can wait. This list helps assess a 20 kW configuration without assuming every circuit must operate together.

To confirm this configuration meets your needs, assess equipment that will operate together and the power required at startup.

Your priority equipment

Identify equipment that must operate simultaneously and loads that can remain off during an outage.

Motor starting

A pump or compressor may require more power at startup than during normal operation. Provide nameplate information to assess these requirements.

Your electrical configuration

Voltage, phase count and connected loads must be considered together. Confirm the configuration before ordering.

Unsure of your power requirements? Send an equipment list and nameplate photos. We can help identify the information needed to select a model.

Plan the connection

Voltage and phases must match your installation. Equal pricing across voltages does not mean the equipment can freely switch voltage. Confirm the ordered configuration before delivery.

Fuel capacity and runtime

Fuel capacity alone does not determine runtime. Consumption varies with electrical load and operating conditions. Specify your desired duration so fuel requirements can be assessed.

Warranty: 1 year or 1,500 hours, whichever comes first. Terms are specified in the quotation.

Data for the configuration shown. The ordered configuration is confirmed in the quotation.

Would you like automatic operation during an outage?

An automatic transfer switch transfers power between the utility and the generator. In a compatible installation, it detects an outage and coordinates transfer to backup power and then back to the utility.

Transfer switch selection and connection must be adapted to your installation with a qualified professional. Its price is specified separately in the quotation.

Plan with your installer

Priority circuits and transfer equipment
Location, ventilation and exhaust according to manufacturer requirements
Access for delivery and maintenance

Your questions before choosing

Can it supply my entire building?

That depends on actual loads, simultaneous use and starting requirements. Floor area or room count alone cannot determine the required output.

How is runtime determined?

Runtime depends on fuel capacity, consumption at the operating load and operating conditions. Confirm load assumptions before relying on a stated duration.

What should I send for a quotation?

Send a priority equipment list, nameplate photos, voltage and phase count if known. Also describe automatic transfer needs and desired operating duration.

How should maintenance be planned?

For the Perkins models shown, do the first break-in service (oil and oil filter) at 60 hours, then plan oil changes every 250 hours and fuel filter replacement every 500 hours. The engine manual also specifies calendar intervals, other tasks and special conditions.
