What this means for you

  • Battery throughput: SG02 handles ~20 % higher charge/discharge current, so faster cycling if you need rapid charge/discharge (e.g. peak-shaving).
  • Physical footprint: SG02 is ~25 % lighter and ~30 mm shallower, making it easier to wall-mount or fit into compact enclosures.
  • Backup capability: SG01’s 100 A passthrough gives a heftier emergency load supply than SG02’s 60 A, so if you plan heavy critical loads during grid-out, SG01 has the edge.
  • Efficiency & performance: Both share the same peak efficiency and grid-compliance; SG01’s MPPT efficiency spec is stated slightly tighter (99.90 %) but in real-world use you’ll see both tracking very near 99 %.

Choose SUN-12K-SG02LP1-AU-AM3 if you prioritise higher battery current and a lighter, more compact unit; choose SUN-12K-SG01LP1-AU if you need maximum passthrough for backup loads and don’t mind the extra size/weight.
