To avoid these issues, a battery should be selected and sized according to several important factors, including solar array size (existing or new), system type (on-grid or off-grid), backup power requirements, and most importantly, the evening or overnight energy consumption (kWh). Oversized batteries - the solar array doesn’t have sufficient power to charge the battery, typically during the winter months. Undersized batteries - do not have enough capacity to meet household demand. This is typically due to two main reasons: Unfortunately, the one-size-fits-all approach is often taken when it comes to sizing a battery which can lead to poor performance and not meeting the consumer’s expectations. This simple solar and battery sizing calculator tool can help you quickly and easily calculate the optimum size solar and battery system for your home or business. However, the remaining 10 to 20% is often available in emergencies, such as a prolonged blackout, depending on how the system is programmed. Therefore, 8kWh of energy can be discharged daily. For example, a lithium battery with a 10kWh total capacity may have its usable capacity limited to 80% to increase its lifespan.
Generally, the usable capacity is limited to 80 to 90% of the total battery capacity to increase the lifespan and avoid a potential battery shutdown at very low charge levels. However, the usable capacity may differ from the total battery capacity. This is the total amount of energy a battery can store. Battery Capacity - kWhīattery size or capacity is measured in kWh (kilowatt-hours). Also, see our introduction to different types of solar systems, including grid-tie, off-grid and hybrid systems.
