 ==== Err 20 - Maximum Bulk-time exceeded ==== ==== Err 20 - Maximum Bulk-time exceeded ====
-This error can only occur when the maximun bulk-time protection is active. 
-This error will not auto-reset. 
-This error is generated when the battery-absorption-voltage is not reached after 10 hours of charging. 
  
-This protection is default disabled ​in all Solar Chargers.+=== Solar Chargers === 
 +The maximum bulk time protection is a feature that was in the chargers when they were just released (2015 or earlier) and later the feature was removed.
  
-It is default enabled on the Skylla-i and the Skylla IP44.+If you do see this error, then update to the latest firmware.
  
-Our advice is to not enable it on solar chargers.+If you then still have the error, perform a reset to factory defaults of the configuration,​ and reconfigure the solar charger.

 Disconnect all wires, and then reconnect all wires. If the error persists the charge controller is probably faulty. Disconnect all wires, and then reconnect all wires. If the error persists the charge controller is probably faulty.

 +Note that this error was introduced in v1.36. So when doing an update, it might look like the firmware update caused this issue; but it doesn'​t. The Solar charger was then already not performing 100% before the update; updating to v1.36 or later merely made the issue more visible. The unit needs to be replaced.

-The typical reason for the error to show is that the charger is configured to operate in parallel using our [[https://​www.victronenergy.com/​live/​victronconnect:​ve-smart-networking|wireless VE.Smart protocol]]; and at the same time it is part of an [[https://​www.victronenergy.com/​live/​ess:​start|Energy Storage System (ESS)]]. Or its used in an installation with an intelligent battery. In all those cases, the charger is being externally controlled, and should not at the same time be configured for parallel operation.+The typical reason for the error to show is that the charger is configured to operate in parallel using our [[https://​www.victronenergy.com/​live/​victronconnect:​ve-smart-networking|wireless VE.Smart protocol]]; and at the same time it is part of an [[https://​www.victronenergy.com/​live/​ess:​start|Energy Storage System (ESS)]].

 Resolution: disable the parallel operation by connecting VictronConnect,​ going to settings, then "​VE.Smart networking"​ and choose "Leave network"​. Resolution: disable the parallel operation by connecting VictronConnect,​ going to settings, then "​VE.Smart networking"​ and choose "Leave network"​.
