Just got my quarterly statement through and genuinely had to read it three times. Up another 23% on last year despite us barely changing our habits. Makes me wonder why I haven't pushed harder to...

@GlenDoug is right to flag that distinction. The adaptive algorithm thing gets conflated with a separate issue — what's more likely here is the charge current dropping below Victron's absorption...
Nice setup — 6kW of solar is serious kit, and Battle Born batteries are well regarded over in the US from what I've seen on various forums. Quite different to what most of us are running here in...

Been through this debate myself when setting up my garden office system last year. Started with a cheap PWM unit from Amazon — can't even remember the brand, it was that forgettable — and honestly...

Been down this rabbit hole recently with my van build and thought it worth raising here as I couldn't find much specific info. I'm running a Growatt SPH series inverter and trying to get it...

Good shout from @Charlie1981 on the UPS function — that's often the missing piece. One thing nobody's touched on yet: transfer switch delay.
Been running a no-name PWM controller I picked up off Amazon for about £18 on my van conversion for just over a year now.

@HollyGaz on the narrowboat — worth knowing that coulomb counting (what the BMV does) drifts over time without clean sync points.

Had almost exactly this with my Honda EU22i last summer — convinced myself it was the carburettor jets blocked with stale fuel, stripped the whole thing down, cleaned everything spotless, and the...
Been down this exact rabbit hole with my static caravan setup — controlling inverter state from the Victron MPPT rather than manually switching things. The short answer is the Victron 150/100...
The narrowboat angle matters here — ambient temp in the hull will swing a lot depending on mooring and season, and chest freezers hate working hard against a warm environment. What's the...

@CopperWelder genuinely laughed out loud at "Simultaneous Truncation" — that wants to be a band name. Right, I'll fill in the blanks from actual experience.
Anyone else noticed that Victron keep quietly shifting the goalposts on LiFePO4 setup with the Multiplus II?

@LindaPrice87 raises the real issue — it's not just build quality, it's what happens when it goes wrong. That said, if AliExpress is genuinely the constraint, Growatt and Deye are the...
@AshDweller raises something important but nobody's mentioned the actual sizing maths yet. Take your panel's Voc, multiply by 1.25 for temperature derating, and make sure your chosen MPPT can...

Had something eerily similar happen on my narrowboat setup last autumn, and it took me an embarrassingly long time to track down the culprit. My MultiPlus-II 48/3000 started behaving like a...
Been doing this for about 18 months now with my garden office setup. Running a Pi 4 with Grafana + InfluxDB stack, pulling data from my Victron MPPT via VE.Direct USB cable.
So this one's been rattling around in my head for a while, ever since I started planning a serious upgrade to the boat's power system. I'm looking at running either a pair of Victron Multiplus-II...

Something I learned the hard way with my garden office setup — the MultiPlus-II is remarkably capable but it will do exactly what you tell it to, nothing more.

@SomersetNomad @DodgyRoamer this is all really useful — just to check my own understanding though, because I run a Victron setup in my shepherd's hut and I'm always nervous about getting this...
