Generac 48kW Standby Generator – XG04845ANAX

The 48kW XG Protector is designed for homes and properties that require substantially more backup capacity than a conventional air-cooled residential generator can provide. With 48 kW of output on both natural gas and propane and up to 200 amps at 120/240V single-phase, it is a strong option for larger Ontario homes with significant electrical demand. Depending on the final electrical design, transfer switch configuration, fuel supply, and load calculation, the 48kW XG may support a broad combination of household essentials, heating and cooling equipment, water systems, major appliances, electronics, and other high-demand loads. Properties with multiple HVAC systems, large pumps, electric heating equipment, EV chargers, hot tubs, pool equipment, electric ranges, dryers, workshops, or other substantial electrical loads still require professional sizing and may benefit from load management.

The Generac 48kW XG Protector Series Standby Generator provides significantly more backup capacity than typical residential air-cooled systems. For many larger Ontario homes, it can provide true whole-home backup potential when the electrical system, fuel supply, and connected loads are properly designed. Depending on the property, a 48kW generator may support lighting, refrigerators, freezers, furnaces, central air conditioning or heat pumps, well pumps, sump pumps, kitchen appliances, laundry equipment, internet and communication systems, garage equipment, security systems, selected water heating, and other important household loads. At 120/240V single-phase, the XG04845ANAX provides up to 200 amps of continuous generator output on either natural gas or liquid propane. However, final backup capability should never be determined by kilowatt rating alone. Motor-starting requirements, simultaneous demand, HVAC equipment, electric heating, EV charging, fuel availability, and customer priorities all affect the final system design.

The XG04845ANAX combines Generac’s 4.5L liquid-cooled engine with the Power Zone® 410 controller and a corrosion-resistant aluminum enclosure. Unlike some standby generators that produce less power when operating on natural gas, this model is rated for the full 48 kW on both natural gas and liquid propane. The generator operates at 1,800 RPM during normal operation and approximately 1,200 RPM during Quiet-Test™ exercise. Standard Mobile Link® cellular connectivity provides remote generator monitoring, while the included ecobee by Generac Smart Thermostat adds intelligent HVAC energy-management capability.
