10.5.4. Battery Conditions
This setting can be used to charge the batteries from the grid should the batteries get too empty. This can occur, for example, at
night or during a long period of bad weather.
In this example, the grid is not ignored when the battery voltage is less than 47 Volt. Do not ignore AC input means that the grid is
accepted because the AC input relay is closed.
The grid will be ignored again when the battery voltage exceeds 52 Volts for more than 5 minutes.
Ignore AC means that the grid is ignored because the AC input relay is open. Apart from “battery voltage”, there are two other
options to choose from: “bulk finished” or “absorption finished”.
Choosing “absorption finished” is a good way to ensure the batteries are getting a full charge every now and then. But it can lead
to a higher electricity bill. The absorption charge stage of a lead-acid battery is much less efficient than the bulk stage.
This could be a reason to choose the “bulk finished” option. At the end of the bulk charge stage a lead-acid battery is about 85%
full.
For more information about bulk and absorption please see the Victron Energy book “Energy Unlimited”, page 25. Follow this

It is also possible to let grid in when the batteries fall below a certain state of charge.
In a DC coupled solar system the “state of charge” option should only be used if you have a GX device in the
system. And the GX device is connected to both the Multi and the MPPT solar charger(s) and/or a BMV
battery monitor. In addition to this a setting needs to be made in the GX device. See this link for more
