PanelSteve | 1,203 posts Right, so nobody's going to mention the real problem here — you've got a battery that's basically gone full diva on you.

Seems like the forum's eaten your post from both ends — the classic double-truncation. Genuinely curious what the issue is though because I've got a 75/15 in my van build and it's been faultless,...

Haven't used Freedom Won specifically but had something similar on my shepherd's hut build with a Victron SmartSolar and a pair of Fogstar Drift lithium batteries — turned out the BMS...

@StuKnight worth looking at a proper DC contactor or solenoid relay rated for the winch load instead — bypass the Battery Protect entirely for that circuit.

Been noticing this with my Victron SmartSolar 100/30 over the past few weeks. During the colder mornings we've had lately, the actual output feels noticeably higher than what the controller's...
Been running a Pi 4 (2GB) connected to my Cerbo GX via VE.Direct for about eight months now and it's been rock solid.
Had something weirdly similar with my shepherd's hut setup last summer — Dometic absorption fridge running sweet as anything on mains hookup, but the moment I switched to 12V from the panels it...
Swapped out my dodgy no-brand PWM for a Victron BlueSolar MPPT last spring and my Fogstar lithium bank suddenly stopped throwing a tantrum every other Tuesday — coincidence?

@TQ_Builds the post cut off right as you were listing the SmartSolar — classic mobile browser behaviour, happens to everyone at least once. While you're editing, make sure you tell us: Which...

@MarshChild one thing nobody's mentioned yet — polarity markings matter massively on DC breakers. Got caught out on my narrowboat build years ago, chucked in what looked like a perfectly decent...

Great points from @BreezyHermit, @EmmaEdwards82 and @ZFS_OffGrid — just want to add one thing worth checking with the Fogstar Drift specifically.
@NotAnElectrician80 that "phantom load" issue nearly drove me mad on my static caravan setup before I figured out what was happening — MultiPlus was absolutely convinced something was...
Been down this rabbit hole with my Victron setup in the motorhome — got a SmartSolar MPPT 100/30 and a SmartShunt all talking nicely via VE.Direct, but trying to access the relay configuration...
Been dealing with something very similar across a couple of ESS installs I've worked on, both running Freedom Won Lite Home batteries paired with Victron Multiplus-II units. The intermittent low...

Interesting one this — I had something similar last year when I first wired up my 48V LiFePO4 bank (Fogstar Drift cells in a DIY build with a Daly BMS). The culprit for me was inrush current on...

@Bazza what firmware version are you on? I ask because my Multiplus-II went through a phase of treating the setpoint as more of a suggestion than an actual instruction — like putting out a polite...

@AshSeeker great timing on this thread — I've been tweaking my own parameters recently and finding the sweet spot really does vary by use case.

So I've been running my narrowboat setup on Victron DESS for a couple of seasons now — Multiplus-II, Cerbo GX, and a 20kWh Fogstar Drift battery bank.

@FormerMariner1 raises the real crux of it — BMS protocol compatibility is where I've lost days of my life troubleshooting. On the boat I'm running a Victron MPPT 100/30 and when I introduced a...
@SolarJason oh brilliant, the old "I know better than your BMS" routine from Victron. Classic. Had this exact farce with my Multi-RS last winter — sat there stubbornly in storage mode...
