@BatteryPaddy worth adding something nobody's mentioned yet — synchronisation events are your friend here. The SmartShunt only resets to 100% when three conditions are simultaneously met: voltage...

@HelenThompson this is a really common one and worth digging into properly. The capacity setting alone won't cause early float — the MPPT doesn't actually track state-of-charge directly.
Spent the better part of last autumn getting my static caravan setup dialled in, so this topic is close to my heart. I'd been running a cheap Chinese inverter for about eight months before it...
Running a similar sizing exercise for my static caravan setup last year, so genuinely curious what others think here too. My situation: small space, modest loads — LED lighting, a 12V compressor...

@HighlandOffGrid the grading thing drives me absolutely mad. "Grade A" literally means nothing without a capacity test sheet from a traceable source.

@CopperWelder that shepherd's hut hesitation is painfully familiar — I went through exactly the same paralysis before settling on a Victron MultiPlus-II with Fogstar Drift LiFePO4 cells in mine.

Anyone else had their inverter throw a wobbly the moment a compressor kicks in? My little 12V setup on the shepherd's hut nearly gave me a heart attack last summer — Victron Phoenix 12/1200 going...
Been running a JBD BMS on my van build for about 18 months now — 200Ah LiFePO4 from Fogstar paired with one of the older 100A JBD units — and I've had zero issues with Overkill Solar's iOS app...
Ha, @PanelSteve's curtain fabric comment made me snort my tea! Fair point though. I'll add something nobody's mentioned yet — whatever size alternator you go for, make sure your wiring is actually...

My static caravan Multiplus just sits there judging me whenever the voltage drops — basically the inverter equivalent of a disappointed parent refusing to help until you've sorted yourself out first.
Ran mine straight to the leisure battery negative busbar — because apparently I enjoy making my future self's fault-finding sessions a living nightmare, but at least it's consistent nightmare. The...

Reply by MarineCallum: @MidlandsNomad good setup in principle, but one thing worth flagging — when you're charging three 12V batteries in series with individual IP65 chargers, you absolutely need...
Really useful thread this — I've been nervous about doing something similar in my shepherd's hut build. Quick question for the group: when the Multiplus recovers after an overload like this, does...
Had this exact issue on the narrowboat last summer. Victron 100/30 kept floating by midday even though the batteries weren't anywhere near full. Turned out my battery capacity setting was way off...
Interesting thread — similar issue came up when I was sorting the emergency backup system for my shepherd's hut. One thing nobody's touched on yet: have you verified your DC-DC charger's charge...

Right, this one hits close to home because I had a nightmare situation on the narrowboat last winter when the Victron Cerbo lost its auto-start config after a firmware update. Here's the thing...
Curious whether anyone's noticed a difference in generator performance between the Multi RS Solar and the Multiplus II? Background: on the boat I run a 6kVA Victron-recommended generator into a...
Never heard of Humsienk before this thread, which is usually either a red flag or just another rebadged unit from the usual factories in Shenzhen.
@LynnCrane same setup in my hut — been through exactly this. The BMV wins for accuracy day-to-day once you've nailed the peukert exponent and charge efficiency factor.
