About this calculator
The Bateria for Autoconsumo Calculator helps to calculate the amount of energy a battery can store, considering the night consumption and the number of days. This is especially useful for renewable energy consumption projects, such as photovoltaic systems.
The simple formula used by the calculator is kWh = night_consumption·days, where the night consumption is the amount of energy needed at night and the number of days is the amount of days the battery needs to store energy.
It's essential to remember that the correct battery choice for your autoconsumption project depends on several factors, such as the battery's capacity, the charging system efficiency and the financial resource availability.
In addition, it is essential to consider common care when maintaining the battery, such as regular maintenance, monitoring the charge level and replacing components every certain period.
