DS ENERGY 12KW Lithium Ion Battery

DS Energy 12kWh Lithium Iron Phosphate (LiFePO4) battery featuring Grade A Tesla cells, a touchscreen monitor, an integrated DC circuit breaker, remote monitoring, and 6-unit parallel scaling represents a high-capacity, heavy-duty energy storage system. It is designed for larger residential properties, off-grid estates, and commercial setups requiring extended backup power. 

System Overview

This battery system delivers a massive 12kWh of usable energy in a single enclosure. To achieve this capacity while maintaining standard solar inverter safety levels, it is configured at 51.2V with a 230Ah to 250Ah capacity. Utilizing Grade A cells (built to high-density EV-grade quality standards), this battery guarantees maximum thermal efficiency, low internal resistance, and superior longevity under heavy daily cycling. 

 Key Features & Component Breakdown

- Grade A Cells: Premium-tier cells that prevent premature capacity fading. They offer perfectly matched internal resistance across the pack, ensuring stable voltage delivery.

- LiFePO4 Chemistry: Offers the highest thermal and chemical stability available for lithium batteries. It eliminates the risk of catastrophic fire (thermal runaway) and lasts significantly longer than standard lithium-ion variants. 

- Integrated Touchscreen Monitor: A door-mounted or front-panel LCD touchscreen. It allows users to view live diagnostics, clear faults, and adjust BMS parameters manually without external tools. 

- Remote Monitoring Function: Connects via Wi-Fi, Bluetooth, or 4G cloud modules. This allows real-time monitoring of energy production, battery temperature, and State of Charge (SoC) via a mobile app or desktop portal. 

- DC Circuit Breaker Protector: A high-amp molded case DC circuit breaker (MCCB) acts as a physical safety barrier. It instantly disconnects the battery pack during massive surges, short circuits, or maintenance.

- 6-Unit Parallel Expansion: Designed with an advanced master/slave BMS configuration. Up to 6 units can be linked in parallel using CAN/RS485 communication cables, scaling your total storage capacity from 12kWh up to 72kWh.

- In-built fire extinguishing system

Inverter Compatibility & Installation Notes

Because of its high current output capability (200A continuous), this 12kWh battery is ideally matched with large 8kW, 10kW, 12kW, or 15kW hybrid inverters (such as Sunsynk, Solark, Deye, Victron, and Growatt). 

Due to the weight of a 12kWh battery pack (typically weighing between 95kg to 120kg), these units are rarely wall-mounted. They are generally designed as floor-standing tower modules or housed in industrial server racks equipped with heavy-duty caster wheels for safety and ventilation.
