HVBAT71.8KW
📦 Key Specifications
-
Nominal capacity: 71.8 kWh
-
Nominal voltage: ~ 691 V DC (High-voltage configuration)
-
Battery capacity: 104 Ah
-
Rack-mount high-voltage battery system — built into a steel-rack “HV-104-WFRE” unit, ready for installation.
-
Scalable: the system can consist of 3 to 11 modules depending on energy requirement — 9-module rack = 71.8 kWh; larger racks increase capacity accordingly.
-
Built-in Battery Management System (BMS) and management controller — supports parallel connection, hot-swapping of modules, automatic cell balancing and communication.
🧰 Key Features & Benefits
Features:
-
Pre-assembled “plug-and-play” high-voltage battery rack — steel framed, rack-mount design for neat installation and structured wiring.
-
Easy-install design: “click-connectors” and concealed cable compartment reduce complexity and clutter.
-
Hot-swappable modules — individual battery modules can be replaced or added without disrupting the entire system or requiring full shutdown. System auto-balances voltage/cells.
-
Scalable capacity — start with fewer modules if storage needs are modest, expand later (up to 11 modules) for larger capacity.
-
High-voltage design — reduces current for a given power, which can simplify wiring and improve efficiency for large-scale PV + battery systems.
Benefits:
-
Delivers large-scale energy storage (71.8 kWh) in a compact, organized rack — suitable for homes with high load, light commercial sites, or off-grid/backup systems.
-
Modular & expandable — gives flexibility for future capacity increases without replacing entire battery bank.
-
Cleaner, safer installation thanks to rack-mount + cable-management + integrated BMS and connectors — reduces risk of wiring errors.
-
Provides a robust, professional-grade battery solution — built for scalability, reliability, and long operational life (with proper maintenance and good BMS).
-
Compatible with high-voltage inverters (HV systems) and suitable for solar + storage, off-grid, backup, or hybrid setups.
