| observation:electrical.max_parallel_stacks | {"values": [], "note": "NOT RESOLVED - recorded as UNKNOWN in electrical.max_parallel_stacks. The two figures may be scoped differently (battery-side electrical maximum vs per-inverter approved maximum), but Sungrow does not say so, so no silent pick was made."} |
