Hamish1980 | 634 posts @Jim1999 Worth looking at your fridge temperature setting too — a lot of people run them colder than needed, which hammers the compressor duty cycle.

Hamish1980 | 847 posts @VanJim good timing on this question — I went through exactly this decision last year with a similar setup. Short answer: the 30A is worth it if your alternator can handle...

Running a Victron SmartSolar 100/30 with a 200Ah AGM bank and a single 200W panel on the roof of my Transit conversion.

@RogerHobbs one thing worth checking that nobody's mentioned yet — have a look at your cell wire connections at the BMS sense leads.
