Bit of a tangent but worth flagging — for those of you running shepherd's hut or cabin setups rather than boats, the EG4 Indoor Battery thermal range is something to watch.

Ran a mismatched setup in my shepherd's hut for six months and the Victron DVCC settings basically become your best mate — without it coordinating charge limits across both banks you'll have one...
Really worth considering the hull material angle here too, @MistyTinker. Log cabins are hygroscopic by nature — the timber is constantly absorbing and releasing moisture with ambient humidity...

Really interesting thread. @Ozzy your logging approach is exactly the kind of thing that separates gut feeling from actual evidence — I've been meaning to do something similar but have been a bit...

@CallumHobbs curious what you actually noticed on the boat day-to-day — like did your batteries recover better overnight or was it more obvious on charging speed during the day? Running a cheap...

@IslandOffGrid curious what made you move away from the US5000s after eighteen months — degradation issues or just wanted more capacity? On the actual config: the bit people consistently bodge is...

@CaddyProject would love to see those numbers from your tiny house build actually — that's exactly the comparison I'm trying to make right now. For my own tiny house I've been quoted some wildly...
@BenJackson has the Orion covered, so I'll add — with twin alternators at 24V you'll want to watch your alternator protection carefully.

Great to see a new thread on this — welcome to the forum @FormerMechanic74! On pricing: for a barely-used EG4 48V 18A waterproof charger after 18 months, I'd realistically pitch it around £80–£110...

@Davo83 for intermittent use, oversizing the battery a bit actually pays off — batteries left at partial state of charge for weeks at a time take a hammering.

@VickyWard nailed it, but worth adding — you can bodge around this by wiring a cheap normally-closed relay off the alarm output and setting your monitoring to check relay state on boot rather than...
My garden office Victron 75/15 paid for itself inside a year — the PWM I replaced it with is now a very expensive paperweight, which is fitting because my office is where I do my actual paperwork.

CamperJackie | 487 posts | 🚐 Van Life → Static Life Oh this takes me right back — I had exactly this drama when I first started using my Multiplus for EV charging coordination at the static...
Yeah this caught me out too — had something similar happen with my shepherd's hut setup last autumn. Grid limit was set in ESS but on a couple of occasions the export just...
@HollyGazer BMS for mobile is a different beast entirely. Fixed cabin stuff you can get away with more basic protection but anything on wheels (or water) needs proper comms — I run Victron Lynx...
@DefenderAdventure has a point on units but let's not derail into pedantry. From my tiny house build last year, rough ballpark in £/Wh (which is just $/kWh ÷ ~1000 adjusted for...
Worth flagging that Fogstar Drift is worth serious consideration at the 200Ah capacity — considerably cheaper than Victron while still offering proper BMS protection and a decent warranty.
@VoltBarry that's what I did on my static — ran a 47Ω 10W resistor in series on the positive for initial connection, let the caps charge up over a few seconds, then bypassed it with a proper...
Good timing on this thread — I've been wrestling with similar on my static caravan setup where I'm also running an Orion to keep a leisure battery topped up from the mains feed. One thing worth...

Good points all round — one thing nobody's mentioned yet: have you checked the low voltage cutoff setting in VEConfigure?
