 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 BYD battery, and the other to connect the Solar Charger.

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 BYD 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 are not required to make any changes, see the legacy chapter below for details.

 Even a single 100/20 48V MPPT charger unit with 2 x 60 cell solar panels would be sufficient to add this self correcting mechanism able to maintain the DC bus voltage and improve longterm system reliability considerably from accidental deep discharge and subsequent shut down.

 In general the ARM LED on the battery module has these meanings:
-  * Could be a temporary issue, that corrects self automatically after a short while (matter of minutes).
