Can anyone provide a simple guide to synchronising a generator with a Xantrex inverter/charger? Any help would be appreciated.

    What do you mean by "synchronization"? Modern AC inverter-chargers with AC1 and AC2 (genset) inputs generally take care of synchronization themselves (or "don't care"--Depends on the inverter's specifications/actual operating modes).

    If you are asking about acceptable voltage and frequency ranges for the genset output vs the AC inverter-charger's input--That is something else.

    You don't sync them, They work  independent as I understand it.  No increase in capacity,  the AC run into the inverter/charger handles loads and the inverter/charger will charge the batteries  or  the inverter works independently to provide the power needs.

    - Assorted other systems, pieces and to many panels in the closet to not do more projects.

    It may also help to know details of the generator and inverter models.
    Off-grid.

    My XW6048, syncs itself to the generator as it's qualifying it.  When it's synced, it connects and passes power on thru to the loads, and if there is excess generator capacity, it is used to charge batteries.   If a large load comes online, the battery charging cuts back, and if a really large load occurs, the inverter will kick on and assist the generator, and then go back to charging batteries.
     You have to program EVERYTHING properly for this to work .   And it works well
    When I am running the generator, I can tell by the loading sound, if it's charging, or assisting, and when the blow dryer shuts off !
