String (Sungrow SG-RT) uses one or two MPPTs for whole strings. HMS micros use one tracker per module (four on the HMS-1600-4T). Even roof: string. Shade or east-west: micro. Hybrid only with a listed HV stack.

The SH10RT-20 takes up to 15 kWp DC at 10 kW AC. The SG8.0RT string unit lists 12 kWp recommended PV. Sum module watts, check cold Voc inside the MPP window (200-950 V on SH10RT) and whether you need three-phase.

Sungrow SH-RT yes: 150-600 V Li-ion, Evo2 connector. SG string cabinets no. HMS micros have no HV battery port; storage with micros is AC-side (Hoymiles LB or MS-A2).

It is the unlock tool for the Hoymiles AC trunk connector, not an inverter. It sits with accessories (article 42-137), with the T-knot unlock and sealing caps. The micro itself is an HMS or HMT type.
