V-TAC LiFePO4 Stackable Battery System 30.72kWh (5.12 × 6)

In a world where clean energy and energy independence are increasingly essential, the V-TAC LiFePO4 30.72kWh stackable battery system presents itself as the ideal solution for those seeking performance, safety, and scalability in their solar installation.

Comprised of six 5.12kWh modules, the system reaches a nominal capacity of 30.72kWh and a usable capacity of 24.58kWh, adapting to residential, commercial, and industrial environments.

Its lithium iron phosphate (LiFePO4) technology offers high energy density, greater thermal and chemical stability, and a lifespan exceeding 6,000 cycles. The stackable modular design facilitates installation and expansion while occupying minimal space.

The system integrates protection against overcharge, overdischarge, short circuit, overtemperature, and overcurrent, along with automatic cell balancing and soft start. CAN protocol communication ensures easy integration with inverters from brands such as Deye, GoodWe, Solis, Sofar, Megarevo, and others.

It also includes real-time monitoring of voltages, currents, temperature, and state of charge (SOC), managed by an intelligent algorithm that maximizes performance and extends lifespan.
