 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 battery, and the other to connect the Solar Charger.

+===== 4. Remote ZYC firmware update via VRM  =====
+VRM remote firmware update is typically only for Victron products, however a special ZYC integration allows for this specific third-party battery update via the GX device and VRM without requiring any extra tools or software.
+**Prerequisites**
+Before starting, ensure the ZYC battery is connected to a Victron GX device via CAN-Bus and that the GX device is internet-connected and registered with the Victron VRM portal. You’ll also need the necessary permissions in VRM to perform updates.
+Confirm the GX device is internet-connected with “Full access” enabled in the VRM menu of the GX settings.
+**Updating Process**
+Access the Victron VRM portal, select your installation, and check the device list for the ZYC battery to make sure it is properly detected.
+{{:battery_compatibility:zyc_firmware-3.jpg?700|}}
+**Check for Updates**
+Victron does not store ZYC firmware files on VRM, nor does it know what the latest firmware version is, or if there is an update available.  ZYC updates will need to be downloaded to your computer first from https://www.zycportal.com documentation section so that you can upload them via VRM.
+**Prepare for Update**
+Review any notes or warnings in VRM, ensuring the system is in a safe state for updating.
+While this is a reliable proceedure, there are always risks involved when performing a firmware update. For example in a remote off grid system, if a power outage would would affect someone on site they should be notified first before attempting it.
+**Perform the Update**
+ZYC has prepared a step by step guide here - {{ :battery_compatibility:simpo_5000_update_guide_via_vrm_v1.0.pdf |}}
+There is a screen recording of the process here - {{ :battery_compatibility:update_firmware_through_vrm.mp4 |}}
+Open the device list for the site, click the Firmware update button. If there is no firmware update button; [[https://www.victronenergy.com/media/pg/VRM_Remote_firmware_update/en/remote-firmware-update.html|see here for troubleshooting]].
+Follow VRM’s on-screen instructions to initiate the firmware update, this involves uploading a firmware file obtained from [[https://www.zycportal.com/|ZYCs website]]. Wait for the process to complete.
+If the update fails, restart GX device, retry the update, and if it fails again, contact ZYC for support.
+**Verify the Update**
+After completion, check the battery’s firmware version in VRM and monitor for any system issues. The VRM firmware update is applied to the Master battery, for large systems it can take some time for the ZYC BMS to then automatically update the firmware of the other connected batteries.
+===== 5. Support  =====
 Support for this battery should first come from your ZYC Energy supplier.
