Who knows a simple solution how to realise a signal with the smaller MPPT-charger models (75/10, 75/15 etc.) indicating the Charger produces energy / is loading or active.
Ideally with the help of the VE.direct pin or also the load output.
This is required to realise the idea of an energy management system with long time storage function into an existing LiFe BMS system on a boot.
The larger models use the day detection (irradiated panels) function for this.
Any ideas are welcome.
