Modbus TCP on port 502, unit ID 1. Only units with this dedicated Ethernet port serve the map; older units behind the AI dongle do not. Measurements are input registers, settings holding registers. The grid meter import/export counters are not exposed over Modbus TCP by this firmware. Two battery packs are addressed separately (BMS1 at 1618/1621, BMS2 at 1751/1754). Battery compatibility: AISWEI/Solplanet's hybrid compatibility list (V1.9, July 2026) puts Solplanet's Ai-HB G2 / Ai-HB G2 PRO / Ai-HB G2-E packs alongside Pylontech, Dyness AP-H, Lithium Valley, FEB Powercube and BYD Battery-Box HVS/HVM on the ASW H-series hybrids - https://solplanet.net/wp-content/uploads/2024/12/Hybrid-battery-compatibility-list-V1.9-Jul-2026.pdf."
