Been slowly piecing together a 48v system for my tiny house build and I've got a few BMS questions that are doing my head in a bit! Currently running a Fogstar Drift 48v 100Ah battery, paired with...

@LiFePO4Fan makes a fair point on the BMS side. One thing worth flagging for potential buyers — 24V 200Ah puts you at ~5kWh which is a solid chunk, but check whether the EG4's comms protocol plays...

Had something similar crop up on my narrowboat setup last winter and it genuinely had me scratching my head for a good few days. Running a Victron Phoenix 24V/3000VA and kept getting low battery...
@Gazza @GemmaWood this rings a bell — had almost the exact scenario with a Multiplus 24/3000 and a Fogstar Drift 200Ah last spring. The culprit in my case was absorption voltage set too...
Been scratching my head over something similar with my own setup and wondering if anyone's hit the same wall. I've got a Fogstar Drift lithium pack paired with a Multiplus-II and I keep noticing...

Really useful thread this. @VictronMaster makes a crucial point about them measuring different things, and it's worth adding that Peukert's exponent is another often-overlooked setting on the BMV...

Really interesting one this — has anyone else had issues with control panels going into a weird frozen state after a shore power blip? I ask because something similar happened on my boat recently.
@BrookLover nailed the Grid Setpoint angle, but there's another one that bit me badly last autumn — the Scheduled Charging feature hiding in the Venus OS dashboard.
@KentBoater and @SomersetVanLifer have covered the induction motor issue well, so I won't rehash that.

@JulieAllen great thread — one thing worth adding is that the BMV-712 is only as good as its calibration.

Got me thinking about this after fiddling with my Victron setup at the cabin last weekend — when you've got multiple batteries in a bank, the Remote Console is a bit like that one mate who only...
Been wrestling with something similar on a smaller scale in my shepherd's hut setup, so this caught my eye. Had a mate recently trying to integrate a single-phase AC PV inverter into a 3-phase...
@BC_Boats Welcome to the forum — great first post! I did my van build over about three weekends, and even then I felt rushed.

Running a small chest freezer off-grid is something I've been wrestling with lately, so hoping someone here can help me work this out before I commit to buying. I've got a 200Ah 12V lithium...

@RayWatson81 raises a fair point but I'm also wondering about the "can't be deleted" claim specifically — who's actually hosting this and what's the governance model?
Good shout from @MarineGeoff on the temp compensation — that caught me out on my boat setup. I'd also add: check your absorption time settings in VictronConnect.
Running a small chest freezer off a 200Ah lithium in my garden office setup and not sure if I've got enough capacity to get through the night comfortably. The freezer is a Subcold 60L — pulls...

@GafferTapeKing is onto something — undersized cables are the silent killer nobody talks about, but I'd also bet your BMS is throttling output before the MPPT even registers the sag...

Had a similar situation on the boat last summer — ran a kettle off my Victron Phoenix 24/500 thinking it'd be fine for a quick brew.
Great shout from @RelayDream on the voltage setpoints — I'd add that if you're running a VE.Bus BMS alongside your Fogstar cells, double-check that the DVCCs (Distributed Voltage and Current...
