 The minimum required firmware version for the [[https://www.victronenergy.com/panel-systems-remote-monitoring/color-control|Color Control GX]] is v2.15. It is highly recommended to use the latest firmware version on all connected devices, including CCGX/VGX, Inverter/Charger and MPPTs. There are regular updates to improve performance and reliability.
-In grid connected systems, advanced control functions are configurable in the ESS settings on the [[venus-os:start|Venus-device]].
-In off-grid systems, the system control functions from the Pylontech Battery Management System (BMS) are built into the latest version of the [[venus-os:start|Venus-device]].
 === 1.3 All 48V Multi, MultiPlus, MultiGrid and Quattro are compatible ===

 The Pylontech manual contains additional diagnostic and troubleshooting information, specifically around decoding any indicator LEDs.

+===== 9. FAQ and Known Issues=====
+==== The maximum charge and discharge current is limited to 25A, but the data sheet tells me the maximum is 100A. ====
 The maximum current is limited to keep the battery healthy and reach the 10 year guarantee. In off-grid, the inverter can draw more than the 25A limit to run the loads, make sure you have sufficient batteries installed to keep the load per battery around this limit.
-**After charging the battery the charge current often changes between 0A and 25A.**
+==== After charging the battery the charge current often changes between 0A and 25A. ====
 This is caused by cell balancing inside the battery. This happens with new batteries and after a deep discharge.
+==== My system isn't charging at the rated capacity, or my PV is shutting down ====
+Pylontech's BMS will restrict the Charge Current Limit of the battery in cold weather. The precise temperatures and limits are not published by Pylontech, but anecdotally from reports on [[http://commmunity.victronenergy.com|Victron Community]] it would appear that batteries begin to be limited below 18 degree C, severely limited below 10 degrees C, and completely restricted from charging below 2 degrees C.
+You can confirm if this is affecting your installation be entering the Pylontech Battery menu on your Venus-device, and then the Parameters Menu. This will report the Charge Current Limit (CCL) and Discharge Current Limit (DCL).
