Product Introduction
This 16kWh low-voltage lithium iron phosphate storage system caters to European households that run photovoltaic setups, aiming to maximise self-generated solar usage and provide reliable backup supply during grid failures. All energy cells are newly produced A-grade LiFePO4 units sourced from reputable original manufacturers. We do not utilise pulled, rebuilt or second-hand cells of any kind. Every individual cell integrates a dedicated explosion relief valve to elevate inherent safety. The cell chemistry delivers a service life upwards of 8000 charge and discharge cycles, and permits a 95% depth of discharge, allowing users to utilise nearly all of the 16kWh stored energy without excessive wear on the cells.
The unit is fitted with a JK 2A high-current active balancing battery management system. This hardware continuously tunes cell voltages and keeps the disparity between individual cells below 5mV. Consistent cell voltage slows capacity drift as the system ages and extends the usable lifespan of the whole storage cabinet. Internal power pathways adopt robust 4AWG flexible cables formulated with flame-retardant materials. A DC disconnect switch paired with a fuse forms a dual safety barrier, minimising risks brought by short-circuit events while supporting sustained high-power draw for heavy domestic loads.
A 4.3-inch industrial capacitive touch display is mounted on the front enclosure. Operators can check real-time metrics such as pack voltage, state of charge and operating current directly on the unit without extra hardware. Multiple communication interfaces are built in: Bluetooth, RS485, RS232 and CAN bus. Users link the battery to a smartphone application to track performance remotely, inspect data for every single cell and receive instant alerts once abnormal operating conditions emerge. The onboard BMS contains a complete protection suite, which automatically cuts power in cases of overcharging, excessive discharge, overcurrent, abnormal voltage and extreme temperature.
Classified IP20 for indoor deployment only, this storage cabinet relies on passive natural airflow for heat dissipation. There are no cooling fans inside, so the unit runs silently and does not demand regular servicing or routine upkeep. Before dispatch, every finished 16kWh system undergoes a continuous 72-hour burn-in test with repeated full charge and discharge cycles. Full export documentation including MSDS, UN38.3 and IEC test certificates accompanies each shipment to streamline customs clearance across EU territories. The cabinet adopts a mobile floor layout, equipped with heavy-duty castors fitted with locking brakes. Users can roll the unit to the preferred spot and lock it firmly in place; wall brackets are not required, which greatly cuts installation time and complexity.
Inventory is held at our Polish warehouse. European customers can receive door-to-door delivery within 3–7 working days once the order is confirmed, removing the long waiting period associated with ocean freight. We back this storage system with a 10-year warranty covering all original components, delivering dependable long-term after-sales support for residential solar projects.
