  "notes": "RS-485 device: reach it through a Modbus RTU-to-TCP gateway using the factory serial settings above. MIN TL-X/TL-XH models mirror the 0-124 input block at 3000-3124, so add 3000 to those addresses when the inverter answers only in the upper range. MOD TL3-XH and SPH hybrid models use the 0-124 block plus the 1000+ storage block below. The battery registers are present on hybrid models only; AC charge energy at 112-115 is a warning-code block on non-hybrid models. Values are big-endian integers, high word first. Battery compatibility: Growatt's energy-storage configuration list pairs the SPH/SPA hybrid models with Growatt's own ARK LV (ARK 2.5L-A1), ARK HV (ARK 2.5H-A1 with the HVC 60050-A1 high-voltage controller), AXE LV, ALP LV/APX and GBLI 6532 packs - https://en.growatt.com/ueditor/php/upload/file/20250116/1737021155869617/ENERGY%20STORAGE%20CONFIGURATION%20QUICK%20CHECK%20LIST.pdf."
