How do I stop my Dura I inverter discharging my Batteries to my car via a non-Duracell charger?

There are a few ways to combat this

• Replace with a Duracharger – as part of the Duracell Energy Product Family they can work together and make sure that the Batteries don’t discharge to the Car
• Set a charge on the Dura I inverter using the Duracell energy App, selecting only a 5w to trickle feed at the same times as the car is scheduled to charge. Sometimes this is not possible if opting in for EV controlled intelligent tariffs, as the energy supplier has the control to opt in for a charge where they see a cheap rate at any time providing the car is plugged in.
• Move the grid CT connected to the Dura I, so that it will only see the house load and the Inverter. (everything but the EV charger) This will need an approved electrician, and might require some adjustments to your Electrical layout, between the Grid supply Meter and any Distribution Boards.
