Nur für Wechselrichter mit eigenem Modbus-TCP-Ethernet-Port (z.B. ASW-TH Serie, KACO Blueplanet Hybrid NH3, Port eth 5&6), Protokoll AISWEI "MB001_ASW GEN-Modbus" V2.1.7.
|
||||
Ältere Geräte ohne diesen Port benötigen stattdessen das `solplanet-ai-dongle` Template.
|
||||
Die Import-/Export-Zählerstände des Netzzählers (46443/46445) werden von dieser Firmware nicht über Modbus TCP bereitgestellt.
|
||||
Bei zwei Batteriepaketen (BMS1 + BMS2) je einen Batteriezähler mit Batteriespeichernummer 1 und 2 anlegen.

Only for inverters with a dedicated Modbus TCP ethernet port (e.g. ASW-TH series, KACO Blueplanet Hybrid NH3, port eth 5&6), protocol AISWEI "MB001_ASW GEN-Modbus" V2.1.7.
|
||||
Older devices without that port need the `solplanet-ai-dongle` template instead.
|
||||
The grid meter import/export energy counters (46443/46445) are not exposed over Modbus TCP by this firmware.
|
||||
With two battery packs (BMS1 + BMS2) add one battery meter each, using battery number 1 and 2.
