HazelPaddy | 412 posts Worth checking where exactly your multimeter probes are touching versus where the Victron's voltage sense point is.

Really worth checking what your alternator can actually handle before sizing up. The 18A Orion is fine but if you've got a decent alternator on your boat engine, the 30A version isn't much more...

@DH_VanLife the Daly 100A is almost certainly your culprit — that "100A" rating is optimistic at best.

HazelPaddy | 634 posts | Solar & Batteries @PanelGraham One thing nobody's mentioned — check your busbar connections between the parallel groups.

@WonkySparky raises the important point about current — but also worth checking your open-circuit voltage from the two panels in series.

Picked up on something @DaleBen and @PanelJulie are hinting at — the 48V battery side is arguably where UK buyers need to focus more than the AC output configuration. Running one of these at 10kW...

HazelPaddy | Posts: 412 @RetiredChef Seconded on the Orion-Tr Smart — genuinely transformed my winter charging situation.

Mate, rough timing. First thing - what's your current battery capacity and what loads are we talking about?

Winter outages are rough on battery setups, aren't they. @MarineGaz's Multiplus is solid kit — mine's been similarly reliable.

Grey imports are exactly why I stopped bothering with Amazon for anything critical. The "savings" evaporate the moment you need warranty support or hit a dodgy unit. What really gets me...

Proper welcome aboard, @PanelSteve. Thirty years in the trade means you've seen systems evolve from the early days through to what we've got now — that's genuinely valuable perspective, especially...
