EdMason | 47 posts @Turbo19 A common culprit with LiFePO4 is the synchronisation settings. The BMV needs to "see" a proper full charge to reset to 100% — make sure your charged voltage...

My shepherd's hut runs a similar cobbled-together setup and honestly the Victron MPPT carrying a budget AGM is basically the off-grid equivalent of putting a Rolls Royce engine in a Reliant Robin...

Had this exact situation in the van last winter parked up in the Fens — brutal cold snap, woke up to nothing. One thing nobody's mentioned yet: your heating being the thing that needs power is...

@ZoeGrant great project! Curious what your typical daily usage looks like — have you worked out your actual amp-hour consumption per day yet? I'd also wonder whether your 140A alternator has a BMS...

Finally got my off-grid cabin system sorted — 4x 200W panels, a Pylontech US3000C battery stack, and a Cerbo GX for monitoring.

WillWilliams | 89 posts | ☀️ Solar Tinkerer Good timing on this thread! Done exactly this for my shed setup. Key thing I'd flag that nobody's mentioned yet - don't skimp on the cable sizing.

@ExTrucker VE.Direct is fine for a single MPPT but if you ever add a second unit, save yourself the headache and grab a VE.Direct to USB interface rather than daisy-chaining — the Cerbo only has...
Been scratching my head over something on the motorhome setup this week. Running a Victron SmartSolar 100/30 with 400W of panels (two 200W Renogy mono in series), feeding into a 200Ah Fogstar...

@VanHolly mismatched panels are basically my whole story 😄 Running a very similar cobbled-together situation in my motorhome — picked up panels at different times, different wattages, one's even a...

Been running my static caravan setup for about 18 months now — 4× 200W Renogy panels, a Victron Multiplus-II, and a pair of Pylontech US3000C batteries (hence the username).

Doing exactly this in my shepherd's hut — four dodgy Amazon panels into a Victron SmartSolar 75/15, and honestly the Victron makes up for the panels' sins better than I deserve given what I...

ValleyTony | 412 posts | ⚡ Solar + Batteries My shepherd's hut is essentially always off-grid so every night is a real test, but I did have family staying during the Beast from the East follow-up...

DaiCole | 847 posts Good question @CurrentAffairs. Honestly for a shepherd's hut I'd argue 100Ah LiFePO4 is the realistic floor, assuming you're not running anything daft like an electric...

Been running a Multiplus 12/3000/120 in my off-grid shed setup for about eight months now, paired with 400Ah of lithium and a 600W solar array through a SmartSolar 100/30.

Picked up four 280Ah Fogstar Drift LiFePO4 cells back in February to build a 12V 280Ah bank for the motorhome.

@BordersSolar would be curious to see those figures when you've got them written up. From where I'm standing — built out a 16kWh bank for the garden office last spring using Fogstar Grade B 280Ah...

I've got a 58ft narrowboat and I'm currently running four 110Ah AGM batteries wired in 12V, charged off a 110A alternator via a Sterling B2B and a small 400W solar setup on the roof.

@JennyPalmer worth checking your Voc in low-light conditions using the VictronConnect app — the 100/30 has a minimum operating voltage threshold and on genuinely thick overcast days a single 200W...

Cleggy51 | 203 posts @JakeShaw96 The CTEK will give you a decent baseline but to really know what you've got, you want to do a proper capacity test under load.

Re: Sterling B2B 60A vs Victron Orion 30A — worth paying double for the Victron on a leisure battery bank? One thing worth flagging @Chalky90 — the Orion Smart 30A is non-isolated, whereas the B2B...
