The Generac RA03022ADAL is a 30kW liquid-cooled diesel standby generator designed for permanent backup power applications using 120/240V 1-phase service. This Protector Diesel RA Series model uses a 2.2L diesel engine and is listed with a 130-gallon integrated base tank configuration. The supplied product details identify the unit as a 60 Hz, 1-phase diesel generator with Power Zone 410 control, ±1% voltage regulation, a sound-attenuated aluminum enclosure, and a double-wall fuel tank. Its 130-gallon tank configuration is intended for longer backup planning compared with smaller tank versions, but final runtime depends on load and site conditions. Buyers should confirm load sizing, transfer equipment, fuel storage requirements, external vent and fill planning, and local code requirements before ordering.
The RA03022ADAL is built for standby generator projects where 30kW output, diesel fuel, and 120/240V single-phase service are required. Final system sizing should be based on the property’s actual electrical loads, transfer switch plan, and installation conditions.
This ADAL configuration is listed with a 130-gallon integrated base tank. The supplied product details also note a double-wall fuel tank and code-ready external vent and fill support, helping simplify diesel fuel storage planning when installed according to applicable requirements.
The Power Zone 410 controller includes an external viewing window for generator status and breaker position visibility. The supplied details also list an isochronous electronic governor, smart battery charger, and ±1% voltage regulation for controlled standby operation.
The RA03022ADAL includes a sound-attenuated aluminum enclosure, UV and ozone-resistant hoses, and listed certifications including UL 2200, UL142, and ULC S601. These details support durable outdoor standby placement when installed and maintained by qualified professionals.

The Generac RA03022ADAL is designed for permanent standby generator applications where 30kW output, diesel fuel, 120/240V 1-phase service, and a 130-gallon base tank are part of the project requirements. Its configuration should be reviewed carefully before ordering to confirm voltage, fuel storage, transfer equipment, and site readiness.
