10 kW Continuous Power Delivery (50 A)
Supplies massive instantaneous power to sustain whole-home emergency backup without current derating.
204.8 V Direct High-Voltage Bus
Matches three-phase hybrid inverter voltage windows, ensuring high round-trip conversion efficiency.
Heavy-Duty High-Capacity BU2-HV5 Cells (52.5 kg)
Enhanced thermal dissipation channels maintain low operating temperatures under heavy 50 A cycling.
Compact Single-Column Footprint (0.23 m²)
Preserves valuable garage and utility room floor space in a clean 626 × 365 mm column.
More product details
Delivering 10 kW of continuous discharge from a compact battery creates heavy thermal stress. The B2-10.0-HV5 incorporates enhanced internal cooling channels and heavy copper interconnects to sustain 50 A continuous power.
- Delivers up to 10 kW continuous DC discharge across 2 modules (204.8 V @ 50 A).
- Heavy-duty 52.5 kg chassis provides robust thermal mass and structural heat dissipation.
- Cell-level thermal sensors and active balancing prevent localized degradation across thousands of daily cycles.

Low-profile column with multi-year expansion headroom.
Standing on its heavy-duty base pedestal, this 2-module tower delivers extreme energy density while leaving vertical headroom to add up to 3 additional modules later. Heavy-duty floor pedestal isolates power modules from ground moisture and standing cellar condensation. Expandable up to 5 modules (25.0 kWh) by simply stacking additional BU2-5.0-HV5 bricks on top. IP65 weatherproof enclosure certified for unheated basements, technical utility rooms, and sheltered outdoor alcoves.
Generation stay-on-HV5.
Later modules should match this HV5 face so the column stays one line.
IP65, CAN, outdoor rated.
Charge 0-50 C, discharge -10-50 C, hybrid link on CAN.
Technical data
High-throughput commercial-grade energy storage engineered for residential heat pumps and workshops.
10.0 kWh high-current storage delivering 10 kW continuous discharge across 2 modules.
Stacking two 50 A high-throughput HV5 modules to reach 10.0 kWh at 204.8 V nominal, this system delivers up to 10,000 W of continuous battery power. It easily runs domestic heat pumps, high-power induction cooking, and emergency three-phase backup circuits simultaneously without power dips or thermal current throttling.

Project scenario
High-Power Residences with Heat Pumps & 10 kW Solar Inverters
Homes with 3-phase heat pumps and 8–12 kWp solar needing 10 kW continuous battery power to handle evening kitchen, HVAC, and domestic loads.
50 A discharge delivers full 10 kW power from just 2 modules, whereas standard 30 A systems would require 3 or 4 modules to deliver matching power.
- BoundaryIf the household requires deeper overnight capacity (> 12 kWh) for multi-day winter heating buffers, step up to the 15.0 kWh (3-module) or 20.0 kWh (4-module) tower. ---
