Really glad this thread came up. After years of tinkering across three different setups — the cabin, the motorhome, and the boat — the spec that quietly bit me hardest was self-consumption of the...
Been doing exactly this for about 18 months now in the van build. Running a Pi 4 with a VE.Direct cable straight into my Victron SmartShunt, feeding data into InfluxDB and pulling it all up...
@Robbo yes, get that full description up when you can — the suspense is killing me! 😄 In the meantime, a few common DMC panel oddities I've seen crop up: All LEDs flashing simultaneously —...
@AshChild yeah this is a known gotcha with Victron MPPTs and LiFePO4 — when the BMS disconnects under charge, the controller suddenly loses its load and the output voltage spikes.
LeeParker | 847 posts | ⚡ Solar Enthusiast @BenJohnson95 the comms port dying is really common with the Renogy units - had exactly the same on mine after about 14 months.

Been tinkering with my setup on the narrowboat this weekend and stumbled into something that's been nagging at me — has anyone else noticed what looks like a discrepancy in the Inverter RS Smart...
Been mulling something over and curious whether others have run into this. I've got a 48V bank on my narrowboat — four 12.8V LiFePO4 cells in series (Fogstar Drift 100Ah units).
@BodgeItAndScarper good shout on the Voc — caught me out once with a panel I picked up off Facebook Marketplace.
Been mulling over a similar setup for a project I'm consulting on — a remote highland bothy conversion that currently runs off a diesel three-phase generator with a basic UPS bolted on for the...
Been thinking about this lately as I'm mid-way through rewiring my boat setup and dreading the first power-on moment 😅 So what's everyone's go-to sequence when commissioning a fresh system?
@BatteryPaula same energy in my shepherd's hut — the Victron gods demand you walk past it smugly and never, ever open the app while guests are staying 🐑⚡
Yeah this catches people out. When the Orion XS is in State OFF, DVCC still references the output current limit you've set rather than treating it as zero contribution.
Really glad @CoveMick brought up the cold temperature correction because that's where I've seen people come unstuck even after they've done the maths.
@SolarJunkie don't leave us hanging there mate, the Renogy what — did your cat sit on the keyboard? That said, from my motorhome experience the Renogy 40A can get a bit dramatic in low-light if...
Been through this exact dilemma on the boat. Started out with a Renogy Rover 40A and honestly it was fine for about 18 months, then the comms port died and the efficiency figures started looking...

AC-coupling via the Multiplus II's grid input works a treat — Victron even has a whole frequency-shift curtailment trick built in so it doesn't explode when your batteries are full, which mine...
@VanKev that's exactly where I landed after a winter of frustration. I run a Fogstar Drift 280Ah LiFePO4 bank with Victron Cerbo GX, and I ended up scripting a Node-RED flow that pulls the Solcast...

@DalesOffGrid the truncated post situation is genuinely becoming a thread-within-a-thread at this point. On the actual monitoring question — I've been running a Raspberry Pi Zero 2W on my...
Bit of a niche one but genuinely losing my mind here — anyone else found that DESS refuses to honour a negative AcPowerSetpoint on a multi-phase setup? Running a three-phase arrangement in the van...

So I've been scratching my head over something that happened last week during that absolutely miserable stretch of grey skies we had (classic British summer, cheers for that). My Victron-based van...
