For a full-time build with a 300Ah pack that is the difference between arriving somewhere with a half-charged battery and arriving full. It is also the point where the alternator becomes a serious winter charging source rather than a supplement to solar.\u003c\/p\u003e\u003ch3\u003eMind the alternator and the cable\u003c\/h3\u003e\u003cp\u003e50A at the output is a real load on the vehicle side, so confirm your alternator has the headroom, particularly on smaller vans. Fusing is specified at 75–100A on both input and output, and terminals take 8AWG to 4AWG — use the heavier end for a long run from the cab to a rear locker.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eSame footprint as the 30A but 96mm deep rather than 77mm, so check clearance if you are mounting it in a shallow space.
