SAJ HS2-5K-T2-X (5 kW three-phase hybrid inverter)

SAJ HS2-5K-T2-X is the 5 kW entry point of the HS2 three-phase hybrid ladder, with two MPP trackers, plug-in PV and AC connections and a 7500 Wp array ceiling.

  • 5000 W rated and 5500 VA maximum on a 3L+N+PE connection, 7.2 A rated per phase — three-phase backup on a small house without unbalancing the supply.
  • Battery expansion unchanged from the rest of the ladder: BU2-5.0-HV1/HV5 up to five modules, 5.0 to 25.0 kWh, 180 to 600 V at 30 A each way.
  • 98.0% peak and 97.6% European efficiency, IP65, under 35 dBA, rated to 4000 m.
  • Plug-in PV and AC connectors and a quick-connect battery, so the wall time is short. Under 10 ms to backup.

Selection 2

5 kW rather than 6 kW on the AC side. 37 of the datasheet's 47 rows are identical between the two.

  • Same enclosure: 450 x 626 x 365 mm, 32 kg, IP65.
  • Same battery side: 180 to 600 V, 30 A each way, and the same 'up to 5 BU2-5.0 modules' expansion — 25 kWh behind a 5 kW inverter.
  • Same efficiency: 98.0% peak, 97.6% European.
  • Different: 5000 W rated and 5500 VA maximum, 7.2 A rated output current, and a 7500 Wp PV ceiling.

Yes. The HS2 is three-phase across the whole ladder, and 5 kW is its bottom rung.

  • Connection is 3L+N+PE with 7.2 A rated per phase at 230 V.
  • That suits a small German house on a three-phase supply where a single-phase inverter would unbalance the feed, and it keeps three-phase backup available.
  • For a single-phase site, the AS3 line is the equivalent product.

Configuration 1

The datasheet's scalability row reads 'BU2-5.0-HV1/5, up to 5 battery modules' — 5.0 to 25.0 kWh, and that row is unchanged on the 5 kW column.

  • de-linker sells the BU2-5.0-HV1 and BU2-5.0-HV5 modules and the BC2-HV1 control unit.
  • Note the HS2 takes the BU2, not the BU3: SAJ's configuration document lists the BU3 pairing against the HS3 line separately.
  • The stack is sized against the load profile on the quote.

Installation & wiring 1

Plug-in connectors on both, which is what keeps the install time down on a wall-mounted unit.

  • PV: MC4/H4, two MPP trackers, 16 A per tracker.
  • AC: plug-in connector, with 20.8 A over-current protection and a 45.0 A maximum fault current.
  • Battery: quick connector.
  • Under 35 dBA, so it can sit in a utility room.

Delivery 1

Half pallet, 32 kg net, no dangerous-goods handling. The battery modules ship separately with their own ADR handling.

  • Lead time is confirmed after the order rather than quoted from stock.
  • Priced as B2B net, derived from de-linker's own published HS2 ladder (6K 1230, 8K 1300, 10K 1370), and confirmed on the quote.
