Batteries with a capacity of 5–9.9 kWh are the most popular energy storage for small and medium-sized solar systems. These models are ideal for single-family homes, small offices and holiday homes, where daily energy consumption typically ranges from 10–20 kWh. A capacity of 5–9.9 kWh is sufficient to store energy generated during the day and use it in the evening, thus significantly increasing the self-consumption rate and reducing grid energy demand.

The category includes models based on lithium iron phosphate (LiFePO₄) technology and equipped with BMS (Battery Management System) protection, which guarantee a long service life, high efficiency and safe operation. These batteries are compatible with most hybrid inverters and can be modularly expanded if a larger capacity is needed in the future. The 5–9.9 kWh energy storage units are the perfect choice for those who want to achieve partial or complete energy independence in their home.
