 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. The maximum current is limited to keep the battery healthy and reach the 10 year guarantee.

-**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. 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).
