Key Industrial Features
Ultimate Cycle LongevityGrade A 314Ah LFP cells deliver 6,000+ cycles at 90% DOD — 15+ years of daily operation. LFP thermal stability (>270 °C) and zero-cobalt chemistry provide the lowest TCO for large-scale stationary storage. | 3-Stack High-Density DesignPatented 3-column architecture packs 45 modules (241kWh) into a single rack footprint — roughly 2–3× the energy density of conventional single-column racks. Multiple racks parallel for multi-MWh installations. | Flexible High-Voltage OutputCustom series/parallel module configuration achieves target DC bus voltage up to 768Vdc+ — enabling direct DC coupling with commercial inverters without intermediate DC/DC stages, reducing cost and efficiency losses. |
3-Level Smart BMSComprehensive protection: Level 1 — per-cell voltage/temp/IR across 45 modules; Level 2 — per-column SOC/SOH and fault isolation; Level 3 — rack-level inverter communication and safety interlock. Optional aerosol/perfluorohexanone FSS. | Maintenance-Free StorageUltra-low self-discharge rate enables up to 6 months of storage without maintenance charging — ideal for phased project deployments, seasonal sites, and spare-module inventory. No equalization, no water topping, zero scheduled maintenance. | Elite Energy Density314Ah high-capacity cells deliver superior Wh per kg and Wh per m² vs 280Ah alternatives — maximizing total system capacity within constrained indoor battery rooms and substation footprints. |

Frequently Asked Questions
Q: How does the 3-stack architecture compare to a single-column rack?
The GHR-314's 3-column design arranges modules in three vertical stacks within one rack frame — achieving approximately 2–3× the energy density of a conventional single-column rack occupying the same floor area. A fully loaded GHR-314 holds 45 modules (241kWh) vs typically 12–15 modules (60–80kWh) in a single-column rack. For a 1 MWh installation: 4–5 GHR-314 racks vs 12–15 single-column racks — significant savings in floor space, DC cabling, and BMS coordination points.
Q: How is the DC bus voltage configured for my inverter?
The GHR-314's 3-column modular design allows custom series/parallel arrangements to match your inverter's DC input voltage window — up to 768Vdc+ per rack. This enables direct DC coupling without intermediate DC/DC converters, avoiding the 2–4% efficiency loss and added cost of conversion stages. Provide your inverter model and DC voltage range — E-Able Power engineering configures the module arrangement and validates compatibility within the technical proposal (2–3 business days). Multi-rack paralleling for higher capacity is also supported.
Q: What customization and scalability options does the GHR-314 support?
The GHR-314 is fully configurable. Options subject to project volume: module count per rack (up to 45), DC bus voltage configuration, communication protocol selection (CAN/RS485/RS232), fire suppression type (aerosol or perfluorohexanone), rack color and OEM labeling, and multi-rack paralleling for MWh-scale systems. Paralleling cables, DC combiner boxes, and system-level BMS coordination are designed per installation. 5-year warranty scalable to 10 years.
Q: What installation and maintenance requirements does the GHR-314 have?
Installation: indoor battery room with level floor (rated for ~5,700kg per fully loaded rack), adequate ventilation per local electrical code, and minimum 1m service clearance on all sides. DC cabling from rack to inverter location. Maintenance is near-zero — LFP cells require no water topping, no equalization charging, and no electrolyte replacement. Annual inspection: visual check of module connections, bolt torque verification, and BMS SoH data review. The 3-column design allows individual module replacement without rack disassembly. Remote commissioning support included; on-site engineer available for projects above 500 kWh.
Factory: Dongguan, Guangdong, China. Cells IEC 62619 certified. 5-year standard warranty, scalable to 10 years. Project-specific compliance documentation available on request.

GHR-314 High-Voltage Battery Rack FAQ
Answers about the GHR-314 3-stack high-voltage battery rack — capacity, LFP cells, DC bus voltage, scalability, safety, installation and warranty.
1What is the capacity of the GHR-314 battery rack?
+
The GHR-314 delivers up to 241 kWh per rack from 15 modules per column across a 3-column stack (up to 45 modules, each ~16 kWh), giving high energy density in a compact footprint for commercial and industrial energy storage.
2What battery cells does the GHR-314 use?
+
It uses Grade A LFP (LiFePO4) cells rated 3.2V / 314Ah, delivering 6,000+ cycles at 25°C, 0.5C and 90% depth of discharge. LFP chemistry gives inherent thermal stability, long cycle life and maintenance-free operation.
3What DC bus voltage does the GHR-314 support?
+
The 3-column design supports a high-voltage DC bus up to 768V, configurable in series and parallel to match your inverter's DC input range while reducing current and copper losses.
4How does the 3-stack architecture compare to a single-column rack?
+
The 3-column design stacks three vertical columns in one rack frame, achieving higher energy density and a smaller floor footprint than a single-column rack while simplifying cabling, service access and thermal management.
5What control and communication does the GHR-314 support?
+
It integrates a 3-level smart BMS (cell / column / module) with communication over CAN 2.0, RS485 and RS232, monitoring voltage, current, temperature and fault protection.
6What installation and maintenance does the GHR-314 require?
+
Install it indoors on a level floor with adequate ventilation and load-rated rack mounting. Maintenance is limited to periodic BMS checks and terminal re-torque, with a 5-year warranty and flexible project configuration.
7Can the GHR-314 be scaled or customised for a project?
+
Yes. Module count per rack (up to 45), DC bus voltage and configuration are selectable per project volume and site requirement, so the GHR-314 can be sized for C&I peak shaving, microgrids, solar self-consumption or grid services.
