Had exactly this with my BMV-712 last winter. The shunt itself is fine, but the display unit's got temperature compensation built in — sounds like yours might need recalibrating or the shunt's...
Ran a 200Ah Victron LiFePO4 in my shepherd's hut for two winters now. Winter's where they really shine — the usable capacity beats lead-acid hands down.
Polarity disasters are no joke. Install an Anderson connector with a keyed design—physically impossible to reverse.
Yeah, mine's been a right pain in the arse lately. Victron BMV-712 here, and when temps drop below about 5°C the voltage readings start drifting — nothing dramatic, but enough to mess with your...
Got a 5.12 tucked under my shepherds hut and it's barely broken a sweat even when I'm hammering it with a 4kW load in summer—honestly think the price-per-reliability ratio beats anything else I've...

The thermal story's interesting—mine sits in the narrowboat cabin where ambient swings wildly, and it just doesn't stress.

Running a 5.12 paired with a Victron Multiplus in my setup, and the thermal performance is genuinely impressive—stays well within spec even during peak summer charging.

The real question is whether your battery can keep up with the solar, not the other way round. I'm sat here with a 10kWh LiFePO₄ watching my MultiPlus throttle everything—solar production peaks...

Learned that lesson the hard way myself—had a moment of "just quickly bodge this" in my cabin that nearly cost me a brand new Victron inverter.

Mate, I'm running a measly 4kW into my static caravan and still can't charge an EV without my Victron having an existential crisis—yours will absolutely lose its mind at 8kW trying to push that...

You'll want to check your MultiPlus specs against peak charging draw—if you're pulling more than its AC rating, you're bottlenecked there regardless of solar.

Have you lot checked the thermal management under real load? I've got the 5.12 in my shepherds hut setup with a 3kW array, and the cooling performance is noticeably better than the cheaper LiFePO4...

The Drift's BMS is genuinely solid—been monitoring mine in the garden office for two years now and the cell variance stays within 20mV across the pack.

Ran mine through two winters on the narrowboat paired with a Victron MPPT—no drama whatsoever. The cell balancing on these Fogstars is genuinely impressive, keeps everything sitting at 3.2V even...

Got a Drift 5.12 myself paired with a 4kW array and honestly the longevity talk from @HighlandExplorer resonates.

The real constraint here is your MultiPlus' AC output capacity—what's it rated at? If you're pushing 8kW solar into a standard 5kW inverter, you're already bottlenecked before the charger enters...

Mate, three years without a hiccup and you're still not complaining? That's basically a glowing testimonial in forum speak.

Curious about your actual consumption profile—are you home during peak solar hours? I'm wondering if a DC charger paired directly to the array might bypass the Victron's limitations, but...

Mate, this is exactly why I'm paranoid about my tiny house setup. Before I connected anything, I labelled every single cable with coloured tape—red/black for 12V, then different colours for...

The multiplus can feed a charger, but you're fighting grid-tie limitations without storage. Your 8kW peaks midday—useless at 6pm when most folk plug in.
