Batteries with a capacity of 0–4.9 kWh are energy storage units for low-power solar systems, ideal for holiday homes, smaller households, garages or stand-alone systems. These batteries allow the efficient storage and recharging of the solar energy produced, reducing grid energy consumption and increasing the self-consumption rate. Small-capacity energy storage is perfect for providing basic functions – such as lighting, cooling or operating small household appliances – where there is no continuous grid supply.

The models available in this category use advanced lithium iron phosphate (LiFePO₄) technology, which is safe, long-lasting and has high cycle resistance. The built-in BMS (Battery Management System) monitors the condition of the cells, preventing overcharging or overdischarging. The 0-4.9 kWh batteries are easy to install due to their compact size and modular design, and can even be expanded later if the system's energy needs increase.
