Description

Whole-home power delivery with dynamic phase-unbalanced compensation.

SAJ HS2-10K-T2-X is the flagship 10 kW three-phase residential hybrid inverter delivering 11,000 VA maximum apparent power and 15 kWp solar intake, engineered to power all-electric homes, heat pumps, and induction cooktops with full three-phase backup.

11,000 VA Maximum Apparent Power (16.7 A)
Squeezes maximum three-phase power into heavy household loads and grid export.
15,000 W Solar PV Input (150% Oversizing)
Dual 16 A MPPT channels capture maximum generation across large residential roofs on overcast days.
30 A High-Rate Battery Interface
Delivers fast DC charging to high-voltage storage (such as SAJ B2-HV1 / B2-HV5) at up to 10 kW.
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase circuits to eliminate peak grid demand charges.

More product details

Modern luxury residences feature high-draw three-phase appliances (induction hobs, heat pumps) alongside asymmetric single-phase loads. The HS2-10K-T2-X delivers 16.7 A continuous current with 100% dynamic phase balancing.

Delivers up to 11,000 VA maximum apparent power to handle simultaneous domestic peak loads.
100% phase-unbalanced capability shifts power dynamically to loaded phases to eliminate peak demand charges.
Sub-10 ms automatic transfer ensures zero computer reboots or smart home controller resets.

15,000 W solar intake with automated solar black-start.

Sized to absorb generation from extensive multi-aspect residential roofs, the HS2-10K-T2-X captures high solar yields while direct high-voltage battery coupling transfers up to 30 A into storage. Dual independent 16 A MPPT channels (Isc 19.2 A) optimize 30–38 panel arrays down to 180 V start-up. 30 A high-voltage battery port pushes up to 10 kW continuous DC power into storage (180–600 V). IP65 weatherproof cast-aluminum casing allows clean indoor utility mounting or outdoor sheltered installation (-35 to +60 °C).

32 kg on the wall, like every other size.

450 x 626 x 365 mm at IP65, rated -10 to +50 °C with derating above 45 °C, under 35 dBA. This is the inverter, not the stack: BU2 modules stand separately and are specified on their own pages, which is what lets the storage grow after commissioning.

A BU2 stack at 30 A.

180 to 600 V at 30 A charge and discharge, up to five BU2-5.0-HV1 or HV5 modules on a quick connector - the same port and the same 5 to 25 kWh range the smaller sizes carry. SAJ lists the pairing in its own documents.

14.5 A per phase, 11000 VA.

Rated current is 14.5 A and maximum 16.7 A at 230 V on 3L+N+PE, against 10000 W of real power. Backup holds 10000 VA continuously at 15.9 A per phase and opens to 16500 VA for 60 s.

Technical data

The flagship 10 kW residential energy hub engineered for complete household electrification.

15.0 kWp DC input paired with 11.0 kVA peak apparent backup power.

The top-tier hybrid inverter in the HS2 series, the HS2-10K-T2-X delivers 10,000 W continuous (11,000 VA max) apparent power to utility grids and whole-home backup sub-panels. With 15,000 Wp maximum solar intake, dual 16 A MPPTs, and 30 A battery charge speed, it delivers uncompromising energy autonomy for large all-electric residences.

Project fit

Where this model fits.

Scenarios that show which projects the SAJ HS2-10K-T2-X belongs in, what to verify before quoting, and when another model is the better pick.

Project scenario

Large All-Electric Single-Family Residences (12–16 kWp PV / 30–38 Panels)

Modern detached homes equipped with a 3-phase air-to-water heat pump, induction cooktops, and high baseline domestic loads.

10 kW continuous AC throughput is the true baseline for uncompromised residential electrification, while 15 kWp DC input ensures ample excess power to recharge a 10–25 kWh battery bank on short winter days.

BoundaryIf the roof accommodates fewer than 26 panels (< 11 kWp) and total simultaneous domestic load is moderate, step down to the HS2-8K-T2-X to save capital cost. ---

Product questions

What is the maximum continuous AC export current on this 10 kW model?

16.7 A max output current; 20 A or 25 A 3-pole circuit breaker. The HS2-10K-T2-X delivers a nominal continuous output current of 15.2 A per phase (max output current 16.7 A @ 400 V). A 3-pole 20 A or 25 A miniature circuit breaker (MCB) paired with 5 × 4 mm² copper conductors is standard on the AC distribution board.

Can this 10 kW model run off-grid if the battery is fully drained?

Yes. Automated DC solar black-start restores power at sunrise. When sunrise illuminates the solar panels, the inverter boots up directly from DC string voltage, begins charging the high-voltage battery stack, and automatically re-energizes the backup AC circuits once safe operating thresholds are reached.
