Kohler 20RCAL-200SELS 20kW Generator With Aluminum Enclosure & 200A SE Transfer Switch – Scratch & Dent
The Kohler 20RCAL-200SELS 20kW Home Standby Generator delivers dependable whole-home backup power with premium engineering and ultra-clean electrical output designed to safeguard today’s sensitive electronics. Engineered for homes that demand consistent, stable power, this 20kW unit provides advanced voltage and frequency regulation with less than 5% harmonic distortion—ensuring smooth operation of appliances, HVAC systems, smart-home devices, and computers during outages. With its quiet performance, automated weekly diagnostics, and factory-paired 200A RXT service-entrance rated transfer switch, it’s a complete solution for reliable home protection.
Under the hood, the generator features Kohler’s Command PRO 999cc OHV engine equipped with hydraulic valve lifters—eliminating routine valve adjustments and improving long-term durability. According to the spec sheet (page 3), the RDC2 digital controller provides full-system monitoring, isochronous frequency regulation, automatic start sequencing, an integrated battery charger, USB programming access, and OnCue® Plus Ethernet-based remote management. This makes operation effortless while ensuring the generator responds instantly to power loss with clean, stable output.
Built for outdoor resilience, the 20RCAL includes a corrosion-resistant aluminum enclosure rated to withstand 181 mph wind loads (page 1). The sound-attenuated design uses flame-retardant UL 94 HF-1 foam and a critical silencer to keep noise levels low—just 66 dB during weekly exercise and 70 dB during normal operation (page 3). Designed for easy installation, the unit incorporates direct through-wall electrical and fuel connections, a sturdy aluminum base, and tool-free removable panels for simplified service access. Backed by Kohler’s premium 5-year/2000-hour limited warranty, this generator delivers proven, long-term reliability.
