Stackable V-TAC LiFePO4 Battery System 20.48kWh (5.12 x 4)

In a world where clean energy and energy independence are increasingly essential, the 20.48kWh V-TAC LiFePO4 Stackable Battery System stands out as a smart and safe solution for those seeking performance, reliability, and scalability in their solar installations.

This system consists of four 5.12kWh modules, giving it a nominal capacity of 20.48kWh and a usable capacity of 16.38kWh. It is ideal for residential and commercial projects that require efficient energy management and extended autonomy.

Thanks to lithium iron phosphate (LiFePO4) technology, it offers high energy density, enhanced thermal and chemical safety, and a lifespan of over 6,000 cycles. Its modular, stackable design simplifies installation and allows for future expansions without complications.

The system includes protections against overcharge, over-discharge, short circuits, over-temperature, and overcurrent, along with automatic cell balancing and soft start. Its CAN protocol communication allows direct integration with leading inverters such as Deye, GoodWe, Solis, Sofar, and Megarevo.

The real-time monitoring system allows visualization of critical parameters such as voltage, current, temperature, and state of charge (SOC), optimizing performance through an intelligent algorithm.
