15.36 kWh LiFePO4 lithium battery - DeLong Top Energy 51.2 V 300 Ah | Category A CALB cells

Delong Energy 's 314Ah 51.2V stackable solar battery is designed to meet the growing need for residential energy storage. Featuring high energy density LiFePO4 cells and an integrated intelligent BMS, this battery ensures high reliability, optimum safety and a long life of over 12 years. Thanks to its stackable and mobile design, it is perfectly suited to scalable installations for controlled self-consumption.

The Delong TOP Energy 15 kWh lithium battery is a high-performance, long-lasting storage solution, ideal for residential or professional solar installations.

It is made up of prismatic lithium iron phosphate (LiFePO4) cells manufactured by leading manufacturer CALB, with a capacity of 314Ah. These cells offer excellent stability, enhanced safety and a very long service life, even under intensive use.

The battery operates at 51.2 volts (i.e. 16 cells connected in series - 16S), making it perfectly compatible with most hybrid inverters on the market.

Thanks to its large storage capacity (15 kWh), it can efficiently power a household or small business site, day and night, and greatly reduce dependence on the electricity grid.

Important notice for our customers in Belgium: An environmental contribution of €342.47 excluding VAT will be applied to the purchase of each Delong Energy lithium battery. More information at the bottom of the page.
