Decoding Generator Types: Where Kubota Shines
Before we dive deep into specific Kubota models, it's helpful to understand the broader landscape of generators. Consumer Reports categorizes generators by their intended use and fuel type, and while Kubota's offerings might not fit neatly into every box, understanding the differences helps clarify their unique value proposition.
Portable Generators: Power on the Go (or at Home)
Most people envision a portable generator when thinking of backup power. These movable units are versatile, often running on gasoline, though dual-fuel (gasoline/propane) options are increasingly common. They're excellent for temporary backup or powering tools off-grid.
- General Characteristics: Typically 3,000 to 8,500 watts, push-button electric start is a common feature.
- Kubota's Portable Offerings: While Kubota does make portable models (like the SG70Q), they stand apart. They are almost exclusively diesel-powered, making them heavier and bulkier than typical gasoline portables, but significantly more durable and fuel-efficient for heavy, sustained use. They are designed for professional use rather than casual camping.
- Safety Critical: No matter the brand, portable generators must be operated outdoors, at least 20 feet from your home, with the exhaust pointed away. Carbon monoxide is an invisible killer, and working CO detectors are essential. Many modern portable units, highly recommended by Consumer Reports, feature automatic CO shutoff sensors.
Home Standby Generators: Seamless Power, Always On
These are the "set it and forget it" heroes. Permanently installed outside your home, home standby generators run on natural gas or propane and automatically activate the moment a power outage occurs.
- General Characteristics: Power output typically ranges from 5,000 to 20,000+ watts, capable of powering entire homes. They feature automatic start/stop functions and daily self-diagnosis.
- Kubota's Standby Solutions: Kubota offers robust stationary units (like the E-GEN12 series) that compete in this segment, bringing their diesel engine reliability to home and small business standby power. They excel in fuel efficiency and engine longevity. While brands like Generac might offer broader dealer networks or slightly faster startup, Kubota's integration of its own durable diesel engine is a significant draw for those prioritizing long-term dependability and lower maintenance cycles. Installation is complex and requires a licensed electrician, often costing as much as the unit itself.
Inverter Generators: Quiet, Efficient, but Less Power-Hungry
Inverters are a specialized type of portable generator known for their quiet operation, fuel efficiency, and clean power output (safe for sensitive electronics). They achieve this by throttling engine speed to match power demand, rather than running at a constant high RPM.
- General Characteristics: Ranging from small camping units to larger models up to 7,600 watts. More expensive than conventional portables.
- Kubota's Role: While Kubota is renowned for diesel power, its focus isn't typically on the smaller, gasoline-powered inverter market that brands like Honda or Yamaha dominate. Kubota’s power products are generally built for raw, continuous output rather than ultra-quiet, variable-load applications.
Portable Power Stations ("Solar Generators"): The Indoor Option
These are essentially large, rechargeable batteries. They store electricity and are charged via a wall outlet or solar panels.
- General Characteristics: Best for short-term, indoor needs (apartments, small electronics). Quiet, no emissions, but less powerful and heavier than traditional portables, and require recharging.
- Kubota's Role: Kubota does not produce portable power stations. Their expertise lies in fuel-powered, heavy-duty generation.
Sizing Your Kubota Generator: The Power Equation
One of the most critical steps in buying any generator, especially a heavy-duty Kubota, is correctly calculating your power needs. Overshoot and you waste money; undershoot and you're left in the dark. Generators are measured in watts (W) or kilovolt-amperes (kVA). For most practical purposes, 1 kVA is roughly 0.8 kW.
How to Calculate Your Wattage
List every device you need to power during an outage. Don't forget starting surge requirements for motor-driven appliances (like refrigerators, well pumps, or air conditioners), which can draw 2-3 times their running wattage for a brief moment. Kubota's diesel engines handle these surges very well.
Here are some common appliance wattages as a starting point:
- Refrigerator: 600 watts
- Sump pump: 750 to 1,500 watts
- Portable heater: 1,500 watts
- Window air conditioner: 1,000 watts
- Lights (per bulb): 5 to 80 watts
- Computer: 60 to 300 watts
- Microwave: 600-1200 watts
- Well pump: 1,000-2,000 watts (higher surge)
- Small power tools (drills, saws): 500-1,500 watts
- Welders/Air Compressors (construction): Can be very high, requiring 5,000+ watts and significant surge capacity.
Example: If you need to power a refrigerator (600W), a sump pump (1000W), and a few lights (200W total), your running wattage is 1800W. However, the refrigerator and sump pump will have surge requirements. A 5,000-watt generator is a common baseline for many homes to cover essentials, but for heavy-duty commercial or agricultural use, you'll often need much more. Kubota units range widely, with popular models like the SG70Q offering 7 kW (7,000 watts) peak output, moving up to 10 kVA, 20 kVA, and significantly higher for commercial applications.
