SAJ HS2-8K-T2-X

  • 8000 W rated AC power and 8800 VA maximum apparent power on a three-phase 3L+N+PE connection.

  • Up to 12000 Wp of PV at STC on two MPPT inputs with a maximum DC input current of 16 A / 16 A.

  • Battery port for two to five BU2-5.0-HV1 modules: 180 to 600 V, 30 A maximum charging and discharging current.

  • Backup output of 8000 VA with 16000 VA peak apparent power for 60 s; with the UPS function the switch time is ≤ 10 ms.

8000 W rated AC power, 8800 VA maximum.

On 3L+N+PE the rated output current is 11.6 A at 230 V AC and the maximum output current 13.3 A. The power factor range is 0.8 leading to 0.8 lagging, and the total harmonic distortion of the current (THDi) is below 3 %. Maximum efficiency is 98.0 %, European efficiency 97.6 %.

Two to five BU2-5.0-HV1 modules at 30 A.

The battery port works from 180 to 600 V with a maximum charging and discharging current of 30 A. Two to five BU2-5.0-HV1 modules connect to one inverter, which gives 10.0 to 25.0 kWh nominal and 9.0 to 22.5 kWh usable energy. The battery modules are separate products with their own page.

IP65, natural convection, under 35 dBA.

The inverter measures 450 × 626 × 365 mm (H × W × D) and is cooled by natural convection. It operates from -10 to +50 °C with derating above 45 °C, and up to 4000 m altitude with power derating above 3000 m. Floor mounting and wall mounting are both possible, indoors or outdoors; 50 cm of clearance is kept above, in front and on both sides.

12000 Wp of PV on two MPPT inputs.

HS2

12000 Wp of PV on two MPPT inputs.

The PV side takes up to 12000 Wp at STC, a maximum DC voltage of 1000 V and an MPPT voltage range of 180 to 900 V; the start voltage is 180 V. The two MPPT inputs carry a maximum DC input current of 16 A / 16 A and a maximum DC short-circuit current of 19.2 A / 19.2 A. DC surge protection is integrated; AFCI and RSD protection are optional.

What does the AC side of the HS2-8K-T2-X need at installation?

The AC side is rated for 3L+N+PE, 220/380, 230/400, 240/415 V with a range of 180～280/312～485 V. The maximum AC over current protection is 33.3 A.

Compatibility records

SAJ BU2-5.0-HV1SAJ BU2-5.0-HV1Item number DLK-SAJ-BU250HV1Documented by SAJ

The HS2 takes two to five BU2-5.0 battery modules (HS2/AS2 manual V0.3, PDF p12). Battery voltage range 180 to 600 V. One BU2-5.0 module alone operates at 89.6 to 115.2 V (SAJ's B2 datasheet gives this for the one-module B2-5.0), below the HS2's battery voltage range of 180 to 600 V; the HS2 manual gives two modules as the smallest stack.
