Batterij vullen met onvoldoende zon voor de panelen

In de winter, when there's not enough sun for solar panels, you can fill the battery using dynamic pricing. In summer, excess solar power charges the battery automatically. With dynamic rates, you fill the battery cheaply and use it when rates are high. Today, prices varied from 10 to 26 cents per kWh. Buy when it's cheap, like at 10 cents, and avoid buying at 26 cents. This way, you optimize your energy usage and save money.
