This encompasses both continuous power output, measured in watts, and surge capacity, measured in watts or kilowatts, which handles temporary power spikes during device startup.
- Rated Power (Watts)
The rated power, often referred to as continuous power, signifies the sustained power output the generator can deliver consistently. A higher wattage rating indicates the ability to power more devices or devices with higher energy requirements. For example, a 500-watt generator can comfortably power a laptop, small fan, and LED lights, while a 1000-watt generator might be required for running a small refrigerator or power tools. Matching the generator’s rated power to the combined wattage of intended devices is crucial for reliable operation.
- Surge Capacity (Watts/Kilowatts)
Surge capacity, also known as peak power or starting watts, represents the maximum power output the generator can briefly deliver to accommodate the initial power surge required by some devices upon startup. Devices with electric motors, such as refrigerators or power tools, often require a surge capacity significantly higher than their running wattage. A generator’s surge capacity must exceed the highest surge requirement of any connected device to prevent overloading and ensure smooth operation. For example, a refrigerator with a running wattage of 150 watts might require a surge capacity of 700 watts upon startup.
- AC Output (Voltage & Frequency)
Portable solar generators typically offer AC outlets that mimic standard household power. The voltage (e.g., 120V in North America, 230V in Europe) and frequency (e.g., 60Hz or 50Hz) must match the requirements of the devices being powered. Using an incompatible voltage or frequency can damage sensitive electronics. Verifying compatibility before connecting devices is crucial for safe and effective operation.
