Smart Mode – automatic optimization of your power consumption

The XOLTA app automatically optimizes based on your consumption and actual electricity prices. Unlike AI solutions, Smart Mode is based on a proven algorithm where you can follow and understand every decision made by the app. It continuously adapts to the weather, your consumption, and the market so that you always use or sell electricity at the most advantageous times.

Time of Use

On days with little sun – typically in winter – the battery charges from the grid when electricity is cheap. Later, it supplies power during the expensive hours, so you avoid high prices.

Solar Shift

Sell when the price is high. Charge when it is low. On sunny days, the battery sends excess solar energy to the grid while prices are low.

Energy trading

On sunny days, it sells excess power to the grid when selling prices are high and charges the battery when selling prices are low or negative.

Energy modes

Smart: The smart mode that controls everything automatically. The app optimizes both savings and earnings based on electricity prices, consumption, and solar forecasts. Combines Time of Use, Solar Shift, and energy trading. The benefit is that you always use or sell electricity at the most advantageous times.

Solar battery mode: The simple mode that functions like a classic solar battery. The power is used directly when it is available, and the battery is only charged by excess solar energy. No trading, no optimization—just pure self-production.
