The battery storage system is a state-of-the-art lithium-ion battery. It was specifically designed to fully meet the high demands placed on 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, again features a built-in Battery Management System (BMS) in each module, thus offering a high level of safety. Internally, the individual cells are monitored and balanced, protecting them from overvoltage, overtemperature, deep discharge, and other issues. The battery is compatible with and certified for many available inverters.
Characteristics
Extremely cycle-resistant – over 6000 cycles at 95% DoD
More usable energy content than the predecessor model US3000
Lifespan over 10 years
Absolutely intrinsically safe lithium technology
Compatible with many available inverters
Automatic address assignment when connected to multi-groups
High charging and discharging capacity possible
Integrated BMS
Very high storage density – low weight and compact design
Easy installation thanks to modular design
Absolutely maintenance-free and durable
Built-in soft-start function that is able to reduce the current surge when the inverter is started from the battery.
Dual active protection at the BMS level
Supports wake-up via 5-12V signal from the RJ45 port
Pre-charge function to protect the ESS system from overvoltage
Battery management system in each module
The integrated battery management system in each module protects each battery cell from harmful influences throughout the module's entire lifespan and effectively prevents premature failure.
Protection against:
Deep discharge and overcharging
Overvoltage during charging
excessively high currents during charging and discharging
Over- and under-temperature
Short circuit and reverse polarity
Continuous monitoring of individual cell voltages (cell balance)
Modular design
The system has a modular design and can be precisely tailored to the desired storage capacity by connecting multiple modules. Each storage module consists of a high-performance lithium iron phosphate (LiFePO4) battery and an integrated battery management system (BMS).
High cycle life
The extremely long cycle life of the integrated LiFePO4 cells makes these modules the ideal storage solution for photovoltaic systems. Regardless of whether the solar system is grid-connected or off-grid, this storage system offers several advantages over typical lead-acid batteries and other lithium technologies.
