Battery selection according to renewable energy consumption

Historical data on electricity consumption can be found in Elektrilevi’s self-service. It is possible to save hourly data for the previous 12 months. Based on this, a graph can be created that shows the average electricity consumption per hour for the entire year.

Optimum battery power = average consumption per hour per year.

Optimum battery capacity = 2 to 4 times the average hourly consumption.

• Battery charging takes place at night during the cheapest hours.
• The battery is discharged during the daytime and evening hours when the price is the highest.

The greater the capacity, the greater the energy saving potential.
