Finally getting round to sorting proper solar on my shepherd's hut and I'm a bit stuck on the wiring config.

Not a static situation myself — I'm dealing with a narrowboat and a shepherd's hut — but both have taught me that awkward roof layouts are basically a puzzle worth solving properly before you buy...

@RayPowell at 100Ah usable capacity the chemistry choice really matters. AGM gives you roughly 50Ah usable before you risk premature ageing; lithium (LiFePO4) gives you 80–90Ah from that same...

Something I noticed on my cabin setup — the Victron app's "panel power" figure is calculated from voltage × current at that moment, but it's never going to match the panel's rated output...
@Graham1995 this exact scenario played out on my narrowboat last winter — chaos, cold tea, very grumpy crew. What sorted it for me was enabling PowerAssist AND tweaking the AcPowerSetpoint in...

@Brummie88 Been down this exact road with my cabin setup. The honest answer is — it depends entirely what you're trying to power. A 110Ah AGM at 50% usable depth gives you 55Ah realistically.

Really common with LiFePO4 chemistry generally — the internal resistance climbs sharply in the cold and that's what's causing the voltage sag under load rather than actual capacity loss as...

Has anyone actually checked whether low ambient temps are affecting charge acceptance as well as heat output?

Finally pulled the trigger on sorting out proper power for the garden office rather than running an extension lead across the lawn like some kind of animal.

SaltyViking | Posts: 412 @LochSeeker worth checking your Orion's input voltage threshold settings in the VictronConnect app.

WattCharlie | 312 posts @OllieGraham91 Worth knowing that December/January in the UK you're realistically looking at maybe 1–2 usable sun hours on a good day, and that's if you're not moored up...

@WezFisher same boat here (literally). My Fogstar Drifts did the same thing last winter moored up in Scotland — looked like proper capacity loss but turned out the cells were just cold-soaking...

@OllieThompson73 had exactly this drama last spring fitting out my static caravan build. Missed three restocks before I finally got lucky at half seven on a Tuesday morning — apparently that's the...

Doing a weekend/occasional weekender conversion on a Transit Custom. Space is tight so I'm looking at 100Ah as my battery bank — no more.

DanFisher89 | 47 posts | West Yorkshire Great timing on this thread @SimonKelly - did almost identical after the Boxing Day storms a couple of years back left us without power for 11 hours. One...

ShaunHamilton | 312 posts @RoundTuit solid setup to start with, but overnight EV charging is a different beast entirely.

Good shout from @DODGuy and @Chris1977 on those settings. One thing I'd add — have you looked at the transfer switch settings in VEConfigure?

@KMV_Marine looks like your post got cut off, but I'll hazard a guess you're seeing the controller jump to float before the battery's properly full — classic symptom. Nine times out of ten on...

DalesOffGrid replied: @Roger1983 the flat voltage curve on LiFePO4 makes your cheap shunt about as useful as a chocolate teapot — current tracking drift is the real killer, so splash out on a...
