-Use the Assistant for these systems with Solar chargers, iedc-coupled solar power: +Use the Assistant for these systems with Solar chargers, where you want to disconnect from mains when possible. Which is the third policy on the list.

 +Usage of all other policies of Hub-1 have been deprecated, in favor of [[ess:start|ESS]].

-=== Do I need to connect the Multi or Quattro to the MPPT with VE.Can? ===+=== Do I need to use the VE.Bus to VE.Can interface cable? ===
  
-No it is not requiredjust much recommendedAnd make sure to only use it when grid-feedback is enabeldThe advantages of using the VE.Bus to VE.Can interface are:+No, not anymore since CCGX v1.73See [[https://www.victronenergy.com/blog/2016/11/07/ccgx-v1-73-hub-1-byd-b-box-and-more-lithium-batteries/|v1.73 blogpost]] for details.
  
-  * The MPPT will automatically use the settings from the Multi, no need to configure the MPPT. 
-  * Equalize is managed by the Multi 
-  * The charge states will be synchronized 
-  * No risk that the MPPT switches to float before the Multi does, and therefore backfeeding will stop 
- 
-Notes for systems where the Multi and the MPPT are not communicating (for example an MPPT 100/50 that does not have a VE.Can comm. port): 
- 
-  * Power can still be fed back to the grid! 
-  * Set the absorption and float voltage of the MPPT slightly higher than the same set points in the Multi 
-  * In a Lithium system, make sure that the MPPT can be switched off by the BMS.
