Our read of the datasheet

The SH15T is a 15 kW three-phase hybrid for larger homes with three-phase supply, and the same datasheet covers 20 kW and 25 kW versions. It accepts up to 30 kWp of PV, 200% of the AC rating, on three MPPTs: the first two take two strings at 32 A each, the third one string at 16 A.

Backup is designed for the whole home: a built-in 63 A bypass per phase, switchover under 10 ms, support for 100% unbalanced output, and 15 kW off-grid output with a 25.5 kW peak for 10 seconds when PV and battery power allow. Battery charging can reach 30 kW and discharging 15 kW, at up to 50 A.

Peak efficiency is 98.1% and European efficiency 97.6%. The 15 kW model is naturally cooled and weighs 38 kg. The AU datasheet does not state a warranty term, so check Sungrow's current Australian warranty terms for this model.

We have not tested this inverter. This summary follows from the manufacturer's published specifications, checked 23 September 2026.

Strengths

  • 200% PV headroom (30 kWp on 15 kW)
  • Whole-home backup with 63 A bypass and under 10 ms switchover
  • Two strings on each of the first two MPPTs
  • Supports 100% unbalanced output across phases

Things to check

  • Needs three-phase supply
  • No warranty term on the AU datasheet
  • IP65 rather than IP66
