Pylontech US3000C 3.5kWh LiFePO4 battery

The US3000C (MPN US3000C) from Pylontech is a state-of-the-art lithium battery. It was specifically designed to fully meet the high standards demanded of solar storage systems today. Thanks to the latest technology, maximum safety and a long service life are guaranteed even with regular deep discharges.

The latest battery from the market-leading manufacturer, now with 3.5 kWh per module, once again features a Battery Management System (BMS) built into each module, thereby offering a high level of safety. Internally, the individual cells are monitored and balanced to protect against overvoltage, overtemperature, and other issues. The battery is compatible with and certified for use with many available inverters.

Battery management system in every module

Thanks to the battery management system integrated into each module, every installed battery cell is protected from harmful influences throughout the module’s entire service life, effectively preventing premature failure.

Protection against:

• Overcharging
• Overvoltage during charging
• Excessive currents during charging and discharging
• Over- and under-temperature
• Short circuits and reverse polarity

Continuous monitoring of individual cell voltages (cell balancing)

Modular design

The system has a modular design and can be configured to precisely match the desired storage capacity by connecting multiple modules together. Each storage module consists of a high-performance lithium iron phosphate (LiFePo4) battery and an integrated BMS.

High cycle life

The extremely high cycle life of the built-in LiFePo4 cells makes Pylontech US3000C modules the optimal storage solution for photovoltaic systems. Regardless of whether the solar system is grid-connected or off-grid, the Pylontech storage system offers several advantages over typical lead-acid batteries and other lithium technologies
