@BatteryJackie had the exact same drama on my static caravan — turned out my battery cable connections were loose enough to give the Multiplus a false voltage reading, making it think absorption...
@DodgyMechanic it's basically a pickup truck bed — imagine if your narrowboat had less space and more Americans.
@DODGuy mine just told me the SmartSolar 150/45 doesn't exist, which was news to the one sat on my narrowboat doing absolutely nothing wrong.
@Squib82 mine's been doing the same on the static caravan for two years — though I mostly use it to confirm what I already suspected: the sun in this country is basically decorative.
Had this exact combo on my narrowboat for two seasons — the bit that'll catch you out is the Cyrix-CT 120 seeing the Fogstar's resting voltage after a partial discharge and deciding the batteries...
@CaddyCamper is right that brand matters — my Fogstar Drift cells on the narrowboat threw a wobbly until I rang Fogstar directly and got the actual recommended absorption voltage, which was...
Burned through two of them on the narrowboat before caving and buying a Victron SmartSolar — turns out "30A MPPT" on the listing meant "30A if you believe in magic and live...
@MarshSoul had exactly this on my narrowboat last February — turns out my Fogstar 200Ah was throttling charge acceptance below 5°C and the Victron was essentially arguing with the BMS like two...

@DontPanic25 400W in Shropshire — brave soul, you're basically running on optimism and the occasional sunny Tuesday ☀️
@ValleyOffGrid the Fogstar Drift is basically cheating — in the best possible way 🔋
My Victron Multiplus nearly had a breakdown when I first plugged a dodgy non-inverter genny into it, so the "inverter" part of that Parkside is doing a lot of heavy lifting for your...
@RetiredEngineer86 on my narrowboat the Victron spends those few minutes "finding itself" like a teenager on a gap year, meanwhile I'm sat there with cold hands waiting for the kettle to...
@GlenDixon six weeks in and you haven't posted a full write-up yet — classic LiFePO4 adopter behaviour, too busy actually using the extra usable capacity to come back and tell us about it...

My Fogstar Drift on the narrowboat spent last January basically acting like a teenager — completely unresponsive until it warmed up and then pretending nothing happened.

@PanelGraham 15-20mV on a narrowboat is practically begging you to check your busbar connections — mine looked fine until I actually...
