Details

The Genmax GM5250iA 5250W Starting / 4200W Running Ultra-Quiet Inverter Generator with CO Detector provides reliable, premium pure sine wave power specifically engineered for whole-home backup, emergency storm readiness, and high-demand appliances across Puerto Rico and the Caribbean. Built around an advanced 160cc 4-Stroke OHV (2026 Model), this commercial-grade power plant delivers 5,250 starting watts and 4,200 continuous running watts with an ultra-clean Total Harmonic Distortion of <3% THD. This hospital-grade electrical purity guarantees safe, flawless operation for sensitive inverter mini-split air conditioners, high-efficiency refrigerators, cistern water pumps, CPAP medical devices, computers, and home electronics during extended LUMA grid failures and hurricane season (temporada de huracanes).

Designed for multi-fuel resilience, the GM5250iA gives you maximum flexibility during emergency fuel shortages. Operating efficiently on unleaded gasoline, it enables homeowners to run seamlessly on standard 20 lb or 100 lb LP propane tanks without worrying about stale ethanol fuel gumming up internal carburetors during long storage periods. With an integrated digital fuel valve and automatic choke, cold or warm startups are effortless. The unit operates at an ultra-quiet acoustic profile of just 58–62 dBA, making it ideal for residential subdivisions (urbanizaciones) where low noise is essential.

The intuitive heavy-duty control panel features comprehensive 120V power distribution, including NEMA TT-30R RV / home backup connections and dual 120V 20A GFCI duplexes, plus USB fast-charging ports for personal devices. Real-time digital telemetry monitors operational wattage load, remaining runtime, voltage output, and frequency. Comprehensive safety is engineered into every component, featuring advanced digital CO auto-shutoff sensors, low-oil warning with automatic engine protection, and thermal circuit overload breakers.
