Description

Powering modulating heat pumps while fully recharging storage.

SAJ HS2-6K-T2-X is a 6 kW three-phase residential hybrid inverter with 9.0 kWp solar intake and a 30 A battery charge port, engineered to power domestic heat pumps while charging high-voltage storage with zero clipping on 500W+ panels.

6,000 VA Symmetrical Output (6.6 kVA Max)
Delivers balanced 400 V power to handle heat pump compressors and household loads without grid unbalance.
9,000 W Solar PV Input (150% Oversizing)
Dual 16 A MPPT channels capture ample solar energy across East/West roofs on cloudy days.
30 A High-Rate Battery Interface
Delivers fast DC charging to high-voltage storage, ensuring batteries reach 100% SoC before sunset.
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase circuits without drawing expensive grid electricity.

More product details

On a 5 kW inverter, running a 1.8 kW heat pump compressor alongside domestic baseline loads leaves very little surplus solar power to recharge batteries. The HS2-6K-T2-X delivers 6,600 VA maximum apparent power, giving all-electric homes the exact throughput needed.

Delivers 10.0 A continuous AC output current per phase to handle simultaneous kitchen and compressor loads.
150% DC oversizing channels surplus solar directly into battery storage at up to 30 A continuous DC rate.
Symmetrical three-phase power export eliminates phase-imbalance penalties under European grid standards.

Independent East/West string optimization with IP65 protection.

Dual independent 16 A MPPT trackers (Isc 19.2 A) with low 180 V start-up voltage capture solar generation across separate morning and afternoon roof pitches without current clipping. Dual 16 A MPPT channels optimize split-pitch arrays down to 180 V starting threshold. 98.0% peak conversion efficiency (97.6% European efficiency) minimizes internal thermal heat generation. IP65 cast-aluminum casing allows clean indoor utility mounting or outdoor sheltered installation (-35 to +60 °C).

Backup that doubles for a minute.

6000 VA continuous off-grid, opening to 12000 VA for 60 s - exactly twice the class, which is the shape a starting motor asks for. Changeover is 10 ms or less and 9.6 A per phase carries it.

Five BU2 modules, on SAJ's own list.

180 to 600 V at 30 A charge and discharge, up to five BU2-5.0-HV1 or HV5 modules on a quick connector, 5 kWh to 25 kWh. SAJ lists this pairing in its own documents, so the battery side arrives specified rather than assembled.

32 kg, IP65, under 35 dBA.

450 x 626 x 365 mm on a load-bearing wall, indoors or out, rated -10 to +50 °C with derating above 45 °C. It is the same enclosure as every other HS2 size, so the mounting question is answered once for the whole range.

Technical data

Optimized three-phase residential energy management engineered for electrified heat pump homes.

9.0 kWp solar capacity with 150% DC oversizing for daytime heat pump loads.

Designed for modern households with variable-speed heat pumps, the HS2-6K-T2-X absorbs 9,000 Wp of rooftop solar across dual 16 A MPPT channels and delivers 6,600 VA maximum apparent power. It provides the extra electrical headroom needed to run daytime heating cycles while pushing up to 30 A directly into high-voltage storage.

Project scenario

Electrified Single-Family Homes with Modulating Heat Pumps (4–6 kW Thermal)

Modern all-electric homes equipped with an inverter-driven air-to-water heat pump (approx. 1.2–2.0 kW electrical draw) and an 8–9.5 kWp solar array.

A 5 kW inverter leaves only ~2.7 kW of DC power for battery charging while the heat pump runs. The HS2-6K-T2-X provides 9,000 W DC intake and 6.6 kVA maximum apparent power, ensuring ample solar power to heat the home and top off storage simultaneously.

BoundaryIf the property uses district heating or gas, has no heat pump planned, and roof capacity is under 7 kWp, step down to the HS2-5K-T2-X to save capital expenditure. ---

Product questions

What is the continuous charge/discharge power capability of this 6 kW model?

Approximately 6 kW DC power across high-voltage battery stacks. With its 30 A battery port operating across 180–600 V DC, the inverter delivers up to 6,000 W of continuous DC charge/discharge power, allowing a 10 kWh or 15 kWh SAJ B2-HV1 battery bank to recharge rapidly during peak solar windows.

What size AC circuit breaker and cable cross-section are required?

3-pole 16 A or 20 A MCB; 5 × 2.5 mm² to 5 × 4 mm² copper cable. The inverter has a maximum continuous AC output current of 10.0 A per phase (at 400 V three-phase). A 3-pole 16 A or 20 A miniature circuit breaker (MCB) paired with 5 × 2.5 mm² copper conductors (or 4 mm² for longer runs) is standard for European installations.
