[Beginner] Where to connect the AC converter, on load or directly on battery ?

[DC1MC]

Hello everybody,
as I didn't get any answer on my previous question, I've decided to start with a Victron MPPT 75/15 and two (used) Silicio SE-230 (see attached pic) @50EUR a piece.

I have seen different opinions about connecting the 220 V AC inverter, either on Load output of the charger, or direct in parallel with the battery, I would really appreciate an explanation and recommendation of where is the best to connect it get the most power for some garden tools.

Also any recommendation of a good battery and a ca. 2000W inverter available in Germany will be appreciated.

 Many thanks,
 DC1MC

The charger puts out a higher voltage than the battery alone.  So the decision can be based on reliability (use the battery) or available power (use the charger).
