RMD
It is my understanding based on what I was told (or thought I was told) by the manufacturer of my MPPT regulator. It's a GSL MPPT 30-2. However your discussion is persuasive and I checked again today. The advice was that basically the output of the regulator is shared between the load on the LOAD terminals and the battery. I'm trying to get my head around the difference (if there is one) in effect between that and my previous understanding.
Perhaps it's a subject for its own thread rather than hijack this one.
Boris,
Those panels will be fine in a parallel setup with the Jaycar regulator I linked to. Be aware there are plenty of other brands you could look at, some cheaper some more expensive, but in researching for other people I and they have found this one to be a good performer at a reasonable price.
Right or wrong, I've had perfect results with the fridge connected to the LOAD terminals on the regulator, but as RMD said, thousands (ie, most people) connect the fridge direct to the battery.
In the PDF I've shown a parallel setup. I prefer to use blocking diodes in the output from larger panels like yours to stop backfeed from a lit panel to a shaded or partially shaded one. Again, most people don't bother with this, but I do and it's cheap. Eg,
Diodes. You can leave them out if you wish.
