mvader [3.2 Generic features]
Line 602: Line 602:
 Below features apply to all types of systems when DVCC is enabled: Offgrid, Backup, ESS, marine and others. And applies to all types of batteries: lead batteries as well as lithium batteries, both with and without a CAN-bus BMS connected to the Victron system. Below features apply to all types of systems when DVCC is enabled: Offgrid, Backup, ESS, marine and others.

-  * A user-configurable maximum charge current setting. It works across the whole system. MPPTs are automatically prioritized over the mains/​generator. In case a CANBUS-BMS is connected and the BMS requests a maximum charge current that is different from the user-configurable setting, the lower of the two will be used. This setting is available in the "​Settings -> "​System Setup" menu on the [[venus-os:​start|Venus-device]].+  * A user-configurable maximum charge current setting. It works across the whole system.

This setting is available in the "​Settings -> "​System Setup" menu on the [[venus-os:​start|Venus-device]]. Note that this mechanism only works for Victron inverter/​chargers and Solar chargers. Other chargers, such as Skyllai’s are not controlled and also their charge current is not taken into account. Same for devices of that are not connected to the GX device, such as an alternator. Ofcourse, in theory it might be possible to use the BMV current reading to somewhat overcome this limitation; but thats not so easy to make stable; and hence we’ve decided to not go there. Worded differently:​ the total charge current of the inverter/​chargers and all MPPTs will be controlled. Any other sources will be extra charge current, not accounted for, also not when installing a BMV or other battery monitor.
   * Shared voltage sense (SVS) for VE.Bus devices and VE.Direct Solar Chargers.   * Shared voltage sense (SVS) for VE.Bus devices and VE.Direct Solar Chargers.
     * The system automatically selects the best available voltage measurement. It will use the voltage from the BMS or a BMV battery monitor, if possible, otherwise it will use the battery voltage reported by the VE.Bus system.     * The system automatically selects the best available voltage measurement.
