Reply by Foggy80: @DaleBen Worth checking whether your panel's Vmp is reasonably close to your battery voltage — that's where PWM really starts to show its limitations.

Great setup @Foggy! One thing worth keeping an eye on with timber offices specifically is temperature fluctuations affecting your BMS - I had mine throttle back charging unexpectedly during a cold...

Just upgraded from a cheap 1000W pure sine inverter to a Victron MultiPlus-II 24/3000 on my static caravan setup and honestly wish I'd done it sooner.

My clamp meter was reading like my panels were powering a small city whilst the Victron quietly logged something far more modest — turned out the clamp meter was picking up AC interference from a...

SolarCol | 847 posts @ExChippie30 worth looking seriously at a Zappi or similar EVSE that can operate in "eco" mode — it'll throttle the charge rate dynamically based on surplus...

@BreezyHermit this is exactly what I've been trying to understand with my own setup. Quick question — was the 3°C reading the ambient temp in the compartment, or were you actually measuring the...

Ella1994 | 📍 Yorkshire | Posts: 847 @GoldenTrekker is spot on about that — I've got one of the same blue units sitting on my bench right now and popped it open out of curiosity.

MeganFox | 203 posts Running almost exactly this spec for my garden office — 400W Renogy panels + 100Ah Fogstar Drift LiFePO4.

So I've been scratching my head over this for a few weeks now. I've got a 2019 Transit Custom that I'm slowly converting, and I've already fitted a Renogy 40A DC-DC charger to properly charge my...

Paul1975 | 647 posts @WayneTaylor Worth checking your VictronConnect app and having a look at the battery voltage at the point it's refusing to charge.

I've been putting together a 24V LiFePO4 bank for my off-grid cabin and went with eight Fogstar Drift 280Ah cells wired in a 8S1P configuration.

Chopper72 | Posts: 847 @SolarNotSure the Fogstar Drift is genuinely decent for a ready-made unit — the internal BMS handles balancing reasonably well in my experience, but where it falls short is...

DerekKnight | 1,203 posts | ⭐ Trusted Member Worth mentioning something nobody's touched on yet — check your SmartShunt's temperature compensation settings in the Victron app.

Over winter I had my 200Ah Fogstar Drift LiFePO4 go into low-temperature protection twice while aboard — once at around 3°C ambient inside the boat's battery compartment.

Running a Cerbo GX on the boat for about eighteen months now, and the moment that sold me was sitting in a marina café watching the battery SOC drop in real time whilst a dodgy bilge pump was...

On the narrowboat I've got a Victron tank level sensor wired to my fresh water tank — the Cerbo reads it beautifully alongside everything else on VRM.

@MarshChild beat me to the EV bit but I'll add — running even a granny charger overnight absolutely demolished my assumptions about "small" battery banks on my shepherds hut build, ended...

Just finished wiring up my garden office setup — 4x Fogstar Drift 280Ah cells in a 12V bank with a Victron SmartShunt and a JK BMS (200A version).

Mine's a Victron SmartSolar 100/30 and it's been playing up since the temperatures dropped here in South Wales.
