1: Choose battery capacity only based on load power and power consumption<\/strong><\/p><p>In battery capacity design, the load condition is indeed the most important reference factor.<\/p><p>However, the charging and discharging capacity of the battery, the maximum power of the energy storage machine, and the power consumption time of the load cannot be ignored.<\/p><p>Therefore, the battery capacity cannot be selected only by considering the load power and power consumption, but a comprehensive consideration is required.<\/p><p><strong>Misunderstanding 2: Taking the theoretical capacity

\/><\/p><p>However, in actual applications, the actual capacity of the battery will be different from the design capacity due to factors such as temperature and service life.<\/p><p>And in order to prolong battery life in practical applications, it is generally not allowed to discharge to SOC0%, and the protection power will be set.<\/p><p>This makes the actual available power less, so these factors need to be excluded when selecting the battery capacity, so as to ensure that there is sufficient battery capacity for use.<\/p><p><strong>Misunderstanding 3: The bigger the battery capacity, the better<\/strong><\/p><p>Many users think that the bigger the battery capacity, the better, but we also need to consider the battery utilization rate when designing. If the capacity of the photovoltaic system is small, or the power consumption of the load is small, the demand for battery capacity is not so large, which will also cause waste of battery cost.<\/p><p><strong>Misunderstanding 4: The battery capacity is just equal to the load power consumption<\/strong><\/p><p>Sometimes for the sake of cost saving, the selected battery capacity is almost exactly equal to the load power consumption.<\/p><p>However, due to the process loss, the battery discharge capacity will be less than the battery storage capacity, and the load power consumption will also be less than the battery discharge capacity. Ignoring the efficiency loss is likely to cause insufficient power supply.<\/p><h2 id=\"Battery-capacity-design-in-different-application-scenarios\">Battery capacity design in different application scenarios<\/h2><p>This paper mainly introduces the design ideas of battery capacity in three common application scenarios: self-use (high electricity cost or no subsidy), peak and valley electricity price, and backup power supply (unstable power grid or important load).<\/p><p><strong>\u2460 &#8220;Spontaneous self-use&#8221;<\/strong><br \/>Due to high electricity prices or low photovoltaic grid-connected subsidies (no subsidies), photovoltaic energy storage systems are installed to reduce electricity bills.<\/p><p>Assuming that the power grid is stable, and off-grid operation is not considered, photovoltaics are only used to reduce power consumption of the power grid, and generally there is sufficient sunlight during the day.<\/p><p>Ideally, the photovoltaic + energy storage system can completely cover household electricity consumption.
