Buyeye Posted March 29, 2021 Share Posted March 29, 2021 Hi Elio I need to check if you are connected to the utility grid or not? If you are not connected to the grid then the inverter is working well. The only thing that you could improve is connecting the battery bms to the can port of the inverter as the inverter supports that. If you are connected to a utility grid then you might have an error.
