 Some of our Solar Chargers feature a VE.Direct communication port, some feature a VE.Can communication port, and some feature both. Both of these types of communication ports can be used to connect the Solar charger to the GX Device. Such connection is mandatory, because it is used to regulate charge currents and voltages.
-When planning to use the VE.Can communications port to connect the Solar Charger(s), make sure to select a GX Device that has sufficient CAN-Bus ports. The Color Control GX has only one such port, its VE.Can port, and is therefor not suitable. All other GX Devices can be used, since they have two ports. One can then be used to connect the BSL battery, and the other to connect the Solar Charger.

The Color Control GX has only one such port, its VE.Can port, and is therefor not suitable. The Cerbo-S GX also has only one CAN port, so it is not suitable either. Use a GX device with two CAN-bus interfaces, eg Cerbo GX, Venus GX or Ekrano GX. One can then be used to connect the BSL battery, and the other to connect the Solar Charger.
 (*) with exception of the models “BlueSolar MPPT 150/70 CAN-bus” and “BlueSolar MPPT 150/85 CAN-bus” which are end-of-life since 2019. Legacy systems, historically installed with this configuration using the allow to charge contacts may be possible, speak to your dealer for more information.

 Victron MPPT charge characteristics are automatically configured & governed by the [[venus-os:start|GX device]]. The settings below are a precautionary measure only:
+Select Battery > Preset > Smart Lithium
 ^ MPPT Parameter ^ Setting ^
 |Battery voltage     |48V|
 |Absorption voltage   |55V|
+|Float voltage   |54.8V|
 The MPPT should also be configured correctly in case of the GX device failing and thus not being able to throttle up or down the charging currents and voltages.
