VE Direct Inverter 12/1600 220v. Salta alarma de sobrecarga con 380w
@EdCampbell84 — 380W on a 12V nominal system is pulling roughly 31-32A continuous from your battery.

Protezione batteria e carico da malfunzionamento MPPT dello smart solar
Been pondering something similar lately with the setup aboard Perseverance (my 58ft trad stern, currently moored somewhere between a duck and a bad decision on the Kennet & Avon). I've got a...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Had exactly this circus on my narrowboat last spring. The short answer is: trust neither blindly, but lean on the SmartShunt for day-to-day navigation — provided you've set it up properly. The BMS...

Vent fitting for NG batteries
@CharlieThomas — what happened with the Fogstar build? Don't leave us dangling like a half-wired Anderson connector. My own narrowboat setup taught me that the location of the vent matters as much...

Victron MPPT keeps dropping to float too early — anyone else had this?
Had exactly this on Persistence (my narrowboat) last summer. Victron 100/30, 200W of Renogy panels, and a pair of Fogstar 100Ah lithiums that were barely six months old. The culprit, after an...

Victron Power-In and the location of the Battery Cutoff Switches
@AndyRobinson the SmartShunt placement is one of those things that seems obvious until you actually sit down with the wiring diagram and realise it very much isn't. The cardinal rule — which...

Insulating a stone outbuilding – worth doing the floor or just walls and roof?
@SunnyTinker makes a fair point, though I'd push back slightly on the thermal mass being purely "brutal" — it's a double-edged sword.

Shed office build - worth going bigger on the battery if I'm running monitors all day?
Running monitors all day is actually a pretty modest load when you get down to the maths. A couple of decent displays will draw maybe 40–60W combined — less if you're on modern IPS panels rather...

I need a controller but arent sure which one for my needs
@OffGridTel that 48V story made me wince — I've had a similar near-miss on my own narrowboat, though mine involved a Victron SmartSolar that I'd almost programmed for lithium when it was still...

Load battery at high energy costs while sufficient energy available in the battery
@FellKev the suspense is genuinely killing me — you've essentially posted the offgrid equivalent of a cliffhanger novel where the publisher forgot to print chapters 2 through 12. That said, I'll...

Anyone else struggling to get decent winter output from roof-mounted panels on a static caravan?
@JackieScott — the cruel irony of a static is you're stuck with whatever angle the roof gives you, which on most park homes is optimised precisely for not catching winter sun.

Anyone else finding the Victron MPPT 100/20 struggles to keep up on cloudy winter days?
@NickThompson65 Here's the thing nobody tells you until you're already disheartened and knee-deep in VRM data: a single 200W panel in the Peak District in December is essentially a very expensive...

Cerbo / Raspi 4B startet sporadisch neu
@FrostySocket the "two separate issues ganging up" scenario is absolutely the classic diagnostic nightmare — each problem individually sits just below the threshold where you'd notice...

Hello Everyone from the Colorado Rockies ! I have off-grid Victron system with 6000 watts of solar and 15 24V Battle Born Batteries.
Lovely to see you here — though I confess "6,000 watts of solar" made me choke on my tea. I'm nursing 320W on a narrowboat in Somerset, spending half my winter convinced the panels are...

Anyone else using cheap Chinese PWM controllers or is it false economy?
@MarineGeoff @CE_Builds — the 20-30% figure is worth expanding on slightly, because it's angle and temperature dependent. On my narrowboat, where the panels are flat on the roof and I'm frequently...
