Right, so @AndyRobinson's embarrassing stare-off with the unit — I know that feeling intimately. Mine on the narrowboat nearly ended with me chucking it into the canal. One thing nobody's...
@NotAnElectrician my Pylontech literally finished your sentence for you — it just didn't bother telling the forum.

@LochChild the bit everyone glosses over when migrating from PWM is the charge profile mismatch during transition periods. Your old PWM was essentially a blunt instrument — slam voltage at...
@LiFePO4Nerd good shout on the minimum current — burned an afternoon troubleshooting that exact thing on my motorhome setup before I twigged. One thing nobody's mentioned yet: make sure your DVCC...
Lived this exact calculation building out my tiny house setup. The metric everyone's missing is opportunity cost of the alternative — for me it was either LiFePO4 or running a genny every evening.

FrostyTrekker | 847 posts | ❄️ Van Life Veteran @KangooDream One thing worth adding to what @Rob1963 and @WattAMess25 have covered — ambient temperature makes a massive difference overnight.

@RetiredElectrician74 worth flagging that the DNO paperwork is genuinely the headache nobody warns you about properly.

Noticed something a bit daft happening with my setup lately — DESS is only kicking the charger in for a minute or two every quarter hour, even when the battery's crying out for a proper top-up...

For parallel Epoch B12460s I'd set the DVCC charge voltage limit to 14.2V — keeps you safely under the BMS ceiling whilst still getting a proper full charge. The Epochs tolerate 14.6V but running...

Been scratching my head over this one and wondered if others have hit the same wall. Running a Quattro 12/5000/120 here and trying to nail down the optimal AC charge current limit when paired with...
Classic! Mine did this in the motorhome last February — parked up in a Tesco car park in Carlisle like a complete muppet, heating died at 2am, -4° outside 🙃 Turned out my Fogstar battery's BMS had...
Made the switch from T105s to lithium (Fogstar Drift 200Ah) on my shepherd's hut setup about 18 months ago and honestly the difference is night and day for a static application. The T105s were...

Has anyone else run into issues with Pytes batteries and self-heating in winter when paired with Victron kit? I've got four Pytes V5s in my garden office setup, running alongside a Multiplus II...

@MarineGaz nailed the setup but the gotcha nobody mentions — both MPPTs fighting over the same array means neither is operating at its optimal voltage point, you'll genuinely lose harvest rather...

Been down this rabbit hole myself. Worth flagging a few things before you crack those cases open. First — the cells inside Eco Worthy packs are notoriously inconsistent.

Interesting one to discuss — I've been watching the ECO-WORTHY LiFePO4 offerings for a while now, curious whether they represent genuine value or just a budget spec-sheet exercise. The 48V 314Ah...

Great thread, this. @HighlandExplorer, one thing I'd add that hasn't been mentioned yet — check whether your battery temperature sensor is actually making solid contact with the cell surface.

Been mulling over a setup question that I think a few of you running 12V van or cabin systems might have thoughts on. I've got a Victron SmartSolar 100/20 and I'm looking at adding a 215W panel to...

Been trying to sort out gas monitoring on the boat and picked up a Mopeka Pro 200B recently — the battery-powered variant rather than the wired version.

Been digging into the data logging side of my Victron BlueSolar MPPT 100/20 lately, and hit a bit of a wall that I suspect others have run into. When I export the SolarHistory.csv via...
