Description

Direct high-voltage inverter pairing without multi-cabinet sprawl.

SAJ B2-10.0-HV1 is a 10.0 kWh high-voltage LFP battery tower delivering 204.8 V nominal bus voltage across two stacked 5 kWh modules, engineered for standard residential self-consumption and overnight power independence.

SAJ B2-10.0-HV1
  • 204.8 V Direct High-Voltage Bus

    Reaches optimal operating voltage for three-phase hybrid inverters with just 2 modules, minimizing internal conversion losses.

  • 9.00 kWh Usable Storage Reserve

    Sized to store typical daily surplus generation from 8–10 kWp rooftop solar installations.

  • 30 A Continuous Discharge (6 kW Output)

    Supplies ample instantaneous power to cover simultaneous evening appliance draws without voltage dips.

  • Compact Single-Column Footprint (0.23 m²)

    Occupies only 626 × 365 mm of floor area, fitting easily into tight basement corners or utility garages.

More product details

Operating high-voltage storage at ~200 V nominal minimizes the voltage transformation ratio between the battery and the inverter, reducing heat generation during high-power discharge.

  • 64S series LFP cell string provides 204.8 V nominal, placing inverter DC-DC converters in their lowest-loss operating zone.
  • Delivers up to 6.0 kW continuous power throughput at 30 A to easily run domestic appliances during evening peaks.
  • Integrated sub-BMS electronics balance cell voltages actively across both stacked modules.

Low-profile column with multi-year expansion headroom.

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-HV1 bricks on top. IP65 weatherproof enclosure certified for unheated basements, technical utility rooms, and sheltered outdoor alcoves.

Grows to 25 kWh.

Three more modules take this column to the top of the B2 ladder without a new controller.

IP65, CAN, 30 A.

Outdoor-rated stack, hybrid link on CAN, charge 0-50 C and discharge -10-50 C.

Technical data

The benchmark residential storage tier for standard single-family homes with 8–10 kWp solar.

204.8 V high-voltage tower sized for whole-home evening self-consumption.

Stacking two 5.0 kWh modules to reach 10.0 kWh at 204.8 V nominal, this B2-HV1 tower provides balanced energy storage for standard three-phase households. It captures daytime solar overproduction to power cooking, lighting, and home electronics overnight with zero grid import, operating across a wide 179.2–230.4 V window.

Project scenario

Standard 4-Person Electrified Households (8–10 kWp Solar Arrays)

Standard 4-Person Electrified Households (8–10 kWp Solar Arrays)

Single-family homes consuming 8–10 kWh overnight between 6 PM and 8 AM.

9.0 kWh usable capacity buffers daytime solar surplus perfectly, achieving 80–90% grid self-sufficiency during non-winter months without over-investing in oversized battery banks.

Product questions

Is 10.0 kWh of storage enough to cover a typical family home overnight?

Yes, for standard domestic baselines and evening appliance use. A standard four-person household consumes approximately 8 kWh to 10 kWh of electricity between sunset and sunrise (refrigeration, lighting, entertainment, cooking, and electronics). With 9.0 kWh of usable energy, the B2-10.0-HV1 covers this demand completely during spring, summer, and autumn.

What is the total assembled height and weight of the 2-module tower?

783 mm height (approx. 31 inches); 112.0 kg total weight. * Total Height: 783 mm (626 mm wide × 365 mm deep). * Total Weight: 112 kg (approx. 247 lbs), distributed evenly across the heavy-duty leveling base pedestal.
