Before starting the actual guide let’s have a look at generator wattages.
Generator Wattages Overview
Every generator has two wattage ratings one is Starting/Peak and the other is Running/Rated. Starting watts are the wattage a generator can put initially to start the heavy appliances, starting watts provide the initial inertia to the motorized or heavy appliances; you found them higher compared to the running watts. On the other hand, running wattage is a constant wattage a generator can put for a long time.
