It is quite normal for the prices of energy-related products to increase during the energy crisis. I could not follow the generator prices, but I followed the prices of solar energy systems almost instantaneously. I have personally witnessed exorbitant increases like you have encountered... I think the energy crisis will not be a temporary problem. If you want to buy energy-related products, you can consider purchasing immediately before more demand accumulates. Even if a normalization begins between Russia and the West, it may take much longer for prices to normalize again.
