Q: Please confirm if this unit compatible with Euro 6 vehicle set up with smart alternators ?

Yes it is. You will need to connect the wire provided from your ignition to the renogy. All very simple. People are a little scared or nervous. Good luck. Great device.

Q: does this work as a battery monitor also with the Bluetooth module or would you have to purchase a battery monitor separately?

Hi yeah this monitors the batteries if connected to either solar or mains charger it does prioritise Aux battery 1st so need to make sure that battery is reasonably charged first, as it pulls 50amps charge so if your only pushing in 20amp to Main battery it will flatten main battery then recharge it after aux battery is charged there’s an accessory Bluetooth BT-02 unit available separately £25 direct from Renogy that connects to your phone to show what’s happening hope this helps

Q: can i connnect shore power to this unit to run the camper and to charge the batteries ?

No there is no option for shore power/240V you would have to connect to a 240v/12v charger.

Q: Hi, i want to use 30 amp charger. is it ok to use just 30 amp cable or i need heavier gauge? thanks

If you search on google for the manual for this device, it gives reccomendations for cable gauge based on cable length used. It will also give fuse ratings.
