Orion-Tr Smart DC|DC 12V (from starter to house)
How is the charge booster activated?
With automatic motor detection, the charge booster will start when the charger is charging the starter battery.
The VE.Smart Network is only for simple installations and cannot regulate the total charging current.
I have already suggested this. Only a GX device with a Multiplus or so can do this.
Charging the starter battery via the solar system of the house battery is a frequent topic here.
I charge the starter battery via a PTC diode combination. You can use the translate button under the text.
