@GemmaCooper86 oh this brings back memories from last February in my static — exact same scenario, woke up to a dead system at stupid o'clock. The Drift's BMS cuts charging around 5°C which is...

One thing I'd add — the absorption/float profiles on the Orion-Tr Smart matter loads with LiFePO4. Basic B2Bs often just shove current in with no proper termination, which isn't ideal...

@BarryCrane Honestly, for a single 100W panel into a leisure battery, a cheap PWM is perfectly adequate — you're not losing sleep over MPPT efficiency gains at that scale.

After squeezing every watt out of my motorhome setup (200Ah Fogstar lithium, 400W of panels, Victron MPPT), I'm wondering if the same logic scales up to a proper garden office my missus wants...

Really useful thread, this one. I ran a similar parallel setup in my static caravan before I moved to full off-grid living, and the one thing nobody warned me about was keeping the cable runs to...

Running a 400W roof array (2x 200W Renogy panels) into a Victron MPPT 100/30, feeding a 200Ah Fogstar Drift LiFePO4. Works a treat for the usual stuff — lighting, 12V fridge, laptop.

Curly63 | ⚓ 847 posts @SuffolkExplorer the voltage drop under heavy inverter load is your likely culprit before you even think about jumping to 48V.

@VictronPro good point on winter derating — I learned that one the hard way on my narrowboat setup. One thing nobody's mentioned yet: what's your backup plan for extended bad weather?

Been meaning to post this for a while. Spent most of last weekend fitting a 200Ah LiFePO4 battery (Fogstar Drift, for anyone wondering) under the bed in our 2018 Transit LWB.

Has anyone actually looked at what the 24V battery bank state of charge is when this trips? I had a similar issue with my backup setup and it turned out the inverter was cutting out partly because...

Just wait till you're moored up in the middle of nowhere, engine off, watching the Victron app tell you your Fogstar is sat at 47% — the Orion-Tr Smart basically becomes your new best mate at...

Hey @NicolaTaylor72! One thing worth checking that nobody's mentioned yet — have you looked at your tail current setting in VictronConnect?

Interesting thread — not on a narrowboat but running a Multiplus at my cabin and the seamless transfer is exactly what sold me on it too. Quick question for @HazelDawn though: how are you finding...
@Spud79 I went through exactly this with my garden office build — started cautious on inverter sizing and ended up wishing I'd spent the extra upfront rather than replacing kit a year later. The...

Currently running a 2kW Victron Multiplus on my 48V narrowboat system and wondering if I should have gone for the 3kVA when I had the chance.

Curly63 replied: Yes, running a Compressor fridge (Brass Monkey 35L) full-time in my Sprinter through two UK winters now on a similar lithium setup.

@RobHenderson adding to what @DY_Power mentioned about temperature compensation — if you haven't got a MultiPlus temperature sensor (the VE.Temp dongle), that's almost certainly your culprit.

Not to derail into static caravan territory, but the LiFePO4 journey is the same whatever the vessel.

Has anyone checked the actual low temp charge cutoff setting in the JK app? Mine was defaulting to 5°C but the hysteresis (recovery offset) was set to only 1°C, meaning once it tripped it wouldn't...
