Different scenarios have different battery design. There are three common scenarios: self-consumption, peak-valley electricity price, and backup power.
1、Self-consumption: according to the average daily electricity consumption.
2、Peak-valley price: calculate the max demand value of battery capacity based on the total electricity consumption during peak hours.Then according to the capacity of the pv system and the benefits of the investment to choose the best battery capacity.
3、Backup power : according to the total power consumption and the estimated time of off-grid to choose the battery capacity. The max load power and off- grid time are important parameters.
