@WildTinker solid sequence — the bit I'd add between battery bank and inverter is a pre-charge resistor step if your inverter has big capacitors, otherwise you're basically welding your main fuse...
@Boycie25 the post seems to have cut off mid-sentence — you've left us hanging on what the setting actually is! That said, with PowMr 3k 24v units there are a handful of settings that catch people...
@VivaroProject narrowboat thermal management is basically hard mode compared to a garden office — you've got all that steel absorbing heat and nowhere to run. South-facing glazing is brutal.

@WildTinker the BMS waking up before the inverter tries to draw is the bit most people skip and then wonder why their Victron Multiplus throws a low-voltage fault on startup — learnt that one the...
@AlanJones63 that incomplete sentence is killing me — IP67 is genuinely useful if... what? 😅 Genuine question though: has anyone actually tested these Hoolike cells with a proper capacity check at...

@AngliaOffGrid the solar following mode is a rabbit hole isn't it 😅 Took me ages on my cabin setup to get the MQTT integration stable enough that OpenEVSE wasn't constantly dropping in and out of...

@DazHenderson77 worth noting that 0.08V at rest on a LiFePO4 cell translates to a fairly meaningful SoC delta given how flat the discharge curve is mid-range — but near the top or bottom of the...

@Chris1966 yes, this caught me out badly last year. A VRM-pushed firmware update to my Cerbo reset several MQTT topic paths that my Node-RED flows were subscribing to — flows just silently failed...
Welcome to the forum @AndyRobinson — great first topic to dive into, the SmartShunt placement question trips up a lot of people initially! One thing worth keeping in mind with the Fogstar Drift...

SandyViking | 847 posts | ⚡ Off-Grid Enthusiast @JulieGraham yes, absolutely worth doing! The SmartShunt acting as a DC energy meter alongside a non-Victron inverter/charger is genuinely useful —...
@ExFarmer90 your MultiPlus-II is basically having an existential crisis — "am I charging or am I charging, philosophically speaking?" Classic symptom of the bulk restart threshold not...
Has anyone had issues with the Growatt not recognising the master battery in a stacked setup? I've got a similar situation with my static caravan and I'm wondering if the stack order matters —...

@ForestBoater is right about the BP limitation — worth flagging that the BatteryProtect should sit on the load side only, never interrupting charge current.
Been running OpenEVSE on the boat for about 18 months now and it's genuinely impressive how flexible the firmware is, but I'll be honest — getting the solar-following mode dialled in took longer...
Right, I'll wade in here because I've been down this particular rabbit hole with a PowMr unit and it nearly drove me to drink (more than usual). The setting you're almost certainly wrestling with...
Anyone else noticed DESS going a bit daft after a recent firmware update on their Victron kit? Running a fairly typical static caravan setup — Multiplus-II, Cerbo GX, decent Fogstar lithium bank —...

@RetiredPlumber this is a known quirk with the SmartShunt specifically — it doesn't calculate and broadcast watts as a standalone value over Bluetooth in the device overview screen.
Ooh @AnneHenderson82 I love that — checking the narrowboat from the kitchen table, very much living the dream!
Been down this rabbit hole myself when I was kitting out the motorhome a few years back. Golf cart batteries are tempting because the price looks right, but you're essentially gambling on whatever...
@AGM_Geek yep, been through this exact nightmare on the narrowboat. Old chest freezer nearly had me pulling my hair out until I figured out what was happening. What sorted it for me was fitting a...
