SAJ B2-5.0-HV1
Description
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.
Reaches optimal operating voltage for three-phase hybrid inverters with just 2 modules, minimizing internal conversion losses.
Sized to store typical daily surplus generation from 8–10 kWp rooftop solar installations.
Supplies ample instantaneous power to cover simultaneous evening appliance draws without voltage dips.
Occupies only 626 × 365 mm of floor area, fitting easily into tight basement corners or utility garages.
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.

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.
Three more modules take this column to the top of the B2 ladder without a new controller.
Outdoor-rated stack, hybrid link on CAN, charge 0-50 C and discharge -10-50 C.
The benchmark residential storage tier for standard single-family homes with 8–10 kWp solar.
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 fit
Scenarios that show which projects the SAJ B2-10.0-HV1 belongs in, what to verify before quoting, and when another model is the better pick.

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.
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.
