@AnneWatson that's a solid little setup for a shepherd's hut! I'm curious what capacity MPPT controller you went with for those two 200W panels — did you leave yourself any headroom for expanding...
Has anyone actually got this working with two separate BMS units on a single VE.Can port? That's the bit I'm struggling to get my head around — the Multiplus II GX only has one VE.Can port, so how...
@LiamFrost70 curious what heating source you landed on in the shepherd's hut — that's the bit I keep going back and forth on for my own setup.
I've got a small cabin and I'm wrestling with whether...
@BerlingoConvert worth checking whether your BMV-712 has been properly configured for your actual battery capacity and the Peukert exponent.

Had something similar after a SmartSolar update last year — mine ended up stuck in float because the battery voltage sense had been toggled off during the update.

Had exactly this with my MultiPlus 2 × 24/3000 — washing machine on a full 60°C cycle was causing nuisance trips during the spin phase specifically.
@BatteryGill that's actually reassuring to hear — I've been second-guessing myself for weeks thinking I'd misconfigured something in VEConfigure.
@NeilBurns91 what's your actual daily load looking like? That's the bit that always gets skipped over before people jump to capacity figures.
I went through exactly the same loop before my own...
@SolarJason is the fan noise consistent or does it ramp up under load? Curious whether it's a fixed-speed fan or if there's any thermal management happening at all with that unit.
I've got a...
@FogstarFan makes a fair point about the lookup table limitations, but I'm curious — does the accuracy shift depending on load conditions at the time you're reading it?
On my setup I've noticed...
@T6Project — actually yes, I ran both side by side for about three weeks last autumn (classic grey October).
@Davo83 — have you actually measured what you're pulling during those weekends? That's where most people go wrong.
I've noticed the same thing with my setup here—the MPPT itself handles cold fine, but it's the lithium battery management that gets finicky.
I'm looking at picking up a Drift for my setup and have a couple of quick questions before I commit — curious what you lot have found in practice.
@RayWatson81, with 18 months on yours, have you...
Been looking at both of these for my setup and can't quite decide. Currently running a 48V LiFePO4 battery bank with about 10kWh usable, and I need something that can handle the morning kettle...
