SarahFrost | 312 posts @JakeHall76 Great combination — I run almost exactly the same setup in my cabin in the Scottish Borders!

Ran a Multiplus 12/3000/120 in my van for three years before moving it into the garden office, so I know that transfer switching well. One thing worth knowing on marina hookups specifically —...

PanelChris | 847 posts @LindaPrice87 depends entirely on your loads, really. 400W solar + 100Ah LiFePO4 is a decent starting point but could be tight in winter.

The split charge relay with LiFePO4 is basically asking your alternator to die heroically so your battery can live — the Orion-Tr Smart's current limiting alone is worth the price of admission on...

My narrowboat setup laughs at your panels getting 11 minutes of usable sun in January — though to be fair, 200Ah of Fogstar is doing the heavy lifting when the sky goes full grey flannel for a...

@DownsDweller one thing worth checking before you spend money on more batteries — have you looked at your actual consumption patterns with Victron's VRM portal?

SamStevens60 | 📍 Cambridge Fens @FenlandOffGrid Worth mentioning that on genuinely clear winter days you'll often see a decent spike around solar noon — don't be discouraged by the averages.

Planning the electrical side of my shepherd's hut and going round in circles trying to size the battery bank properly.

Nothing like a Yorkshire winter to humble your solar ego — my panels spent most of January looking like expensive bird perches.

@ExBrickie31 classic Victron "I know best" energy — your absorption voltage is probably set too low so it thinks it's done before it's started, worth checking your charge profile isn't...

@Spider6 those figures are pretty much what I'd expect for Yorkshire this time of year, honestly. January UK solar is brutal — you're looking at maybe 1–2 peak sun hours on a decent day, and...

Dizzy83 | Member @KenCross Something nobody's mentioned yet — check your Multiplus-II's input current limit settings before you start pushing EV charging through it.

BrambleHermit | 847 posts @CrafterDream nice find on the cell matching — that's genuinely rare straight out of the box with Drift cells, suggests a good batch. I've got a similar 24V setup here in...

@DanMurray £25 is a decent gamble — what did the capacity tester actually show? I've been down this road a few times sourcing batteries for my shepherd's hut build.

GrumpyWanderer | Posts: 312 | Location: Array Running the same unit in my Sprinter. The VSR was basically useless once I fitted lithium — relay doesn't know what to do with a flat LiFePO4, just...

PanelChris | Member @KenCross Nice system! One thing worth adding to what @SolarMike's touched on — have a look at the Victron scheduled charging feature alongside an Ohme or Zappi charger.

Been meaning to write this up for a while. Just finished replacing the tired old 3x110Ah flooded lead-acid bank on my Westerly Centaur with a pair of 200Ah LiFePO4 drop-ins (Fogstar Drift units).
Ian White in Marine & Boat 4 months ago thumb_up 4
Great point from @DuctTapeDave62 — worth adding that even if the alternator is rated at, say, 150A, you won't see anything like that available for charging once the vehicle's own loads are...
Silver Captain in Q&A 4 months ago thumb_up 1
@MultiPlusFan decent result, though 200Ah at 12V is only 2.4kWh usable (assuming 100% DoD on the Fogstar, which you obviously wouldn't run) — so you were likely pulling well under 1kWh/day across...
