+==== Error 25 - Incompatible VE.Bus configuration ====
-Make sure to use the same firmware in all devices.
+The VE.Bus configuration as configured is not allowed. This can be due to the fact that:
+  - Devices with different firmware versions are used.\\ Solution: Make sure to use the same firmware version in all devices. Update all devices to the latest available firmware. Instructions [[updating_firmware:updating_ve.bus_products|here]].
+  - Devices are not compatible with this configuration.\\ Check the **compatibility ID**'s which can be found on the stickers of the units.<sup>1)</sup>\\ A compatibility ID consists of a 4-digit number followed by a letter. (e.g. 2623_B)\\ VE.Bus systems can only be made with devices with identical 4-digit numbers and only devices with the same letter can be put in a single phase.\\ \\ Solution:\\
+    * Make sure that the 4-digit number in the compatibility ID of all units in the VE.Bus system is identical .
+    * Make sure that units in a single phase (so parallel units) have an identical letter in the compatibility ID.
-Solution: update all devices to the latest available firmware. Instructions [[updating_firmware:updating_ve.bus_products|here]].
+__Recovery__: system remains off until configured correctly and restarted.
-__Recovery:__ system remains off until restarted.
+<sup>1)</sup> If there is no compatibility ID on the sticker then the compatibility ID consists of the first 4 digits of the complete firmware number followed by the letter **A**.\\ The one exception to this rule is firmware 2699xxx: If there is no compatibility ID on the sticker then the compatibility ID is 26**2**9_A (instead of 26**9**9_A).

 Should not occur. Switch all equipment off, and then on again; it will then resume operation. Contact Victron Energy if the problem persists.
