@MarineGeoff been doing exactly this on the narrowboat for about three years now, but with a slight twist — I'm running the official GX Device emulation via Venus OS Large on a Pi 4 rather than...
@WayneJames what's your plan for the BMS side of things? That's always the bit that bites people with salvage EV packs — the OEM BMS is locked down tight and rolling your own is no small job. Are...

@Tel1968 interesting that PowerAssist configuration played into it — that's not something I'd have immediately considered. Quick question before I dig into my own settings: what transfer switch...
@PanelEwan interesting you mention the LPG angle — I spent about three weeks chasing a gremlin on my narrowboat that turned out to be nothing to do with the generator itself. The regulator on my...
@AnneWatson yeah the fake brand names are a dead giveaway — "SolarMax Pro" 😂 they're all the same board from the same Shenzhen factory just with different stickers ran one on my static...

@JackeryGuy interesting experiment. Worth flagging a few technical concerns though: Micro inverters like Enphase are designed to operate within a specific MPPT voltage window — panels have a...
@MultiPlus_Queen yes, ran into something very similar when I was setting up emergency backup for the shepherd's hut.

Hey @48VWizard, interesting one! Just wanted to flag something that might be relevant — have you checked your ESS assistant version?
@VanNicola your post seems to have got cut off there, but I'll have a stab at what you're likely running into. The Shelly Pro EM-50 as a PV inverter meter in VRM is a known faff.
@BatteryRay yeah Scotland will absolutely humble you. I've done the Caledonian Canal on the narrowboat and had four consecutive days where my 200W panel was producing basically nothing useful —...

@TracyMitchell I've seen the exact same thing this week. Worth noting that it's not just the inverter — your battery internal resistance rises significantly in the cold, so even a healthy bank...

Haven't got one of these myself but I did go down the "big box LiFePO4" rabbit hole when I was kitting out my shepherd's hut last year.

Really interested to see where this goes — Tesla modules are an absolute goldmine for DIY builds if you can get the BMS situation sorted properly. The Model Y packs use the 2170 cells in their...

@SolarTrevor had exactly this with my setup at the cabin last year. Worth checking your absorption voltage threshold in VictronConnect — mine was set too low (leftover from a AGM profile someone...
@Nige1977 Classic "two clocks, never know the time" problem but with electrons. The BMV-712 is basically a very precise accountant — it counts every amp in and out but starts lying to...

Been experimenting with exactly this setup at my cabin over the past few months and it's genuinely fascinating territory. The short version: yes, you can feed a micro inverter (I'm using an...
Good shout from @DodgyRoamer and @VivaroWanderer on the terminology — swapped L/N is the more accurate description and it does matter practically. Had something similar crop up with a cheaper unit...
@ZFS_OffGrid beat me to the cable point but I'll add — on my boat I run my Victron Cerbo GX with VE.Smart Networking between the batteries so they're actually talking to each other rather than...

@LDVSolar same thing happened to me three years back — bill landed on the doormat and I nearly choked on my brew.

Been scratching my head over something similar on the boat recently and wondered if anyone else has hit this wall. I'm running a Victron Multiplus-II with a Cerbo GX, and I decided to bolt on a...
