-
High‑quality electrical output
Brushless alternator and tight voltage/Hz regulation produce ultra‑low harmonic distortion, protecting motors, controls, and sensitive electronics.
-
Fast automatic standby response
Automatically detects utility failure and starts within seconds, minimizing downtime for critical systems.
-
Quiet, weather‑ready design
Sound‑attenuating enclosure remains <61 dB in normal operation and meets 181 mph wind load ratings, making it suitable for close‑to‑structure installations.
-
Dual‑fuel flexibility
Runs on natural gas or liquid propane, allowing integration with existing fuel infrastructure and extended standby readiness.
-
Advanced controller & diagnostics
The RDC2 digital controller offers LCD readout, programmable exerciser, and built‑in charger, aiding setup and maintenance.
Q&A
Q: What power does this generator deliver?
A: It delivers 23 kW (LP) / ~21 kW (NG) of continuous standby power at 277/480 V three‑phase — ideal for commercial buildings or large 3‑phase residential systems needing reliable backup power.
Q: What applications is it best for?

Maintenance Tips
-
Oil & Filter Changes: Replace engine oil and filters every 100–200 hours or annually to prevent engine wear and ensure smooth operation.
-
App Connect Monitoring: Track performance, receive alerts, and detect issues remotely for proactive maintenance.
-
Coolant System Care: Maintain proper coolant levels and flush periodically to prevent overheating of the liquid-cooled engine.
-
Air Filter & Spark Plugs: Clean or replace regularly to maintain efficient combustion, reliable starts, and fuel economy.
-
Weekly Exercise Cycle: Automatic test runs keep internal components lubricated and generator ready for outages.
-
Load Testing: Run under actual or simulated load to ensure stable voltage, frequency, and full-capacity performance.
-
Fuel System Check (NG/LP): Ensure consistent fuel supply and clean lines for uninterrupted operation.
-
Battery & Electrical Connections: Check battery charge and terminals for reliable automatic startup.
-
Enclosure Maintenance: Keep the corrosion-resistant aluminum enclosure clean and ventilated to prevent overheating and extend lifespan.
