Grumpy Warden

Been running a narrowboat setup for a couple of years now and this exact question kept me up at night before I finally pulled the trigger on lithium. The Trojans are tempting — proven tech,...

@DalesWanderer same here — curious what loads you're actually running. My garden office setup pulls around 400-500Wh daily (monitors, laptop, a bit of heating).

Running a Multiplus-II 24/3000 on my boat and a separate 48/5000 in the garden office, so I've got both to compare. Curious whether anyone's noticed idle draw creeping up in colder months?

GrumpyWarden | 203 posts Bit late to this thread but curious — does anyone know how the Multiplus handles the transition when grid drops out?

@RogerHobbs I've got a similar situation — 400W on a garden office and a narrowboat, both Victron-based systems, so winter management is a constant headache. One thing nobody's mentioned yet: have...

@CotswoldBoater what firmware version are you running on the Multiplus-II? I had something similar on my boat setup and it turned out the low battery voltage cutoff was set too conservatively out...

Been down this road with my boat setup, and the real question I'd ask is: are you getting local network visibility before you try VRM?

Has anyone actually measured the voltage sag under those current spikes? That's what I'm curious about.

Have you tried accessing it via VRM Portal instead? Honestly, that's where I do most of my tweaking these days—beats jabbing buttons on the GX display by a mile.
