 +
 +Loss of mains detection will push and pull at voltage and frequency to see if there is still a generating source. This process can cause issues with some generators, or high impedance connections to generators. 
 +
 +For large and stable Generators Type B LOM will work, and is safer.
 +However, if you are experiencing issues with voltage, frequency or power fluctuations, you may wish to try Disabling LOM.
 +
 +**Disabling LOM**
 +
 +Disabling the LOM on an input connected to the grid is only allowed when other external safety equipment is installed.
 +Disabling the LOM on an input connected to generator can be done, but then other methods / warning signs / physical lockout safety measures must be provided. Ensuring that any installer that will work on the generator, wiring or system, will make sure to also switch off or otherwise disconnect the Inverter/charger system.

If you have an existing generator that is not able to supply the maximum charging current of the Multi, you will need to adjust the AC Input Current Limit in the General Tab of VEConfigure.
  
 A reasonable starting point for the AC Current input limit is 80% of the generator capacity in Watts. For example:  A reasonable starting point for the AC Current input limit is 80% of the generator capacity in Watts. For example:

 This leading or lagging power factor will have the effect of demanding more kVa from the generator for the same or less DC Watts delivered to the batteries. You may need to further reduce the DC Current Limit in the Charger tab of VEConfigure if the generator continues to overload after changing this setting. This leading or lagging power factor will have the effect of demanding more kVa from the generator for the same or less DC Watts delivered to the batteries.

 +Effectively, the total charge current possible will be less that the rated maximum charge current output of the charger (under normal conditions) when weak AC is disabled.

-There can be issues with generators with Residual Current Devices (RCD's), control electronics or circuit breakers. There is some discussion about troubleshooting these issues on this [[https://community.victronenergy.com/questions/1702/multiplus-with-generator-and-residual-current-devi.html|Victron Community Question - Multiplus With Generator And Residual Current Device]], however as troubleshooting and correcting these faults have serious safety implications, they are best discussed with a local installer who has appropriate electrical qualifications, or your Victron Dealer.+As troubleshooting and correcting these faults have serious safety implications, they are best discussed with a local installer who has appropriate electrical qualifications, or your Victron Dealer.

 +Simplify the AC wiring, With everything safely shut down and tested for voltage, disconnect the AC-Output active, neutral and earth. Direct wire in the generator connections, with no other bus bar links. A common neutral can cause issues.
  
 If there is still no connection, contact your dealer or distributor. Tell them the steps that you have taken already to attempt to get it to work and they can help from there. If there is still no connection, contact your dealer or distributor.
