24V 2.1kWh stackable lithium engery storage battery from the ProAutarch Battery System with BMS and LCD-Panel in a 19 inch casing of the 4rd generation, for a variety of uses e.g. as an emergency backup battery or a solar battery. The module consists 240 high-quality, refurbished Li-Ion cells and is completely new. Its compatible to the PBS 24-2100-25 of the 3rd generation.
technical details
This is a stackable lithium-battery-module for 24V systems. This module is compatible to the 24V 2.1kWh module of the 3rd generation and can be stacked together with them. It can release 2.1kWh per discharge cycle. In a parallel configuration with other modules, this capacity can be increased to 4.2kWh (2 stacked modules), 8.4kWh (4 stacked modules) or 16.8kWh (8 modules inside of a rack) respectively. Additionally, a serial connection allows for 48V as well as other setups. The 19" casing can be stored in any commercially available 19" rack. This casing is 36cm deep, hence 6cm more long than generation 3. However, it still fits the regular short racks. With the attached feet, it can also be used and stacked without such a rack. The mainswitch serves as a disconnecter to turn the module off and on. The permanent LCD-Panel shows the charging status and all of the essential information independent of the connected load. The M8 terminals provide sufficient space for 3 cable lugs at a time, therefore enabling the use of 3 cables per terminal.
