Prioritize solar over shore power with the BMV-712

Victron Energy has with the release of GX OS 3.1 introduced an impressive feature that allows users to prioritize solar over shore power. It's an innovative function that unfortunately requires you to have a MultiPlus or Quattro installed to use.

But there are several options to achieve the same prioritization of solar energy without having to make the big investment in a MultiPlus or Quattro. In this blog post, we will describe how you can achieve this with relatively simple means.

The BMV-712 is a battery monitor that offers a smart solution. By using the relay that is integrated behind the instrument and configuring it for "Charger mode" in the Victron Connect app, you can choose when the relay should be activated.

In the following In the following example, we have configured the relay as follows; that it is activated when the battery reaches either 60% capacity and is charged with the land current charger to 90% and so on; as long as the battery is between 61-100% only the battery and energy from the solar panels are used.

By then connecting the relay output to the "Remote" input on a Phoenix Smart IP43 charger creates a smart solution . På så Thus, the charger will only be activated under the conditions described above. This means in practice that the charger will only be activated when the solar energy cannot maintain the battery level on; own hand. På In this way, with very simple means, we have succeeded in prioritizing solar energy before land current.

If your charger lacks a dedicated input for remote control, there is an alternative access method. You can instead use the rel output from BMV-712 for controlling a 230V relay; and onå så so check the charger.
