Help with Connecting OpenEMS to GoodWe Hybrid Inverter ETplus+

[stefan.feilmeier]

Hi Nada,

just like MrT described it depends on whether you are are using the inverter as an “ESS” or as a “BatteryInverter”:

• Use ESS if you have a battery connected that is directly communicating with the GoodWe, e.g. a BYD Battery Box. Then OpenEMS only controls the inverter.
• Use BatteryInverter if OpenEMS talks to both the battery and the inverter directly. This allows deeper optimization and is used e.g. in FENECON systems.
