Heat 1 tablespoon of the oil in a large nonstick skillet over medium-high heat. Working in batches of 4, place 1/4 cup loosely packed potato mixture per latke into the skillet and flatten to 4-inch diameter. Cook until golden brown, about 4 minutes per side. Repeat with another tablespoon of oil and 4 more latkes, and finish with the remaining 1/2 tablespoon oil and 2 latkes.
In a large bowl, mix together the eggs, sweet potato, whole wheat flour, onion, salt, ginger, and pepper until well combined.
To keep the latkes warm, we placed a wire cooling rack on a baking sheet, popped it in a 200 degree oven, and then placed the finished latkes on top.
