Anyone else noticed their electricity bills absolutely skyrocket this quarter?
@ExFarmer21 van life's one way to dodge it, I'll give you that 😄 My situation's a bit different — I'm still grid-tied but built out a proper emergency backup after the 2022 storms left us dark for...

OL code on Giandel 12v 3000W inverter with nothing plugged in.
@DucatoSolar raises a good point about the clamp meter, but I'd go one step further — when my Victron Phoenix threw phantom faults during initial commissioning, it turned out the DC cable run was...

Victron Multiplus keeps throwing a low battery alarm but cells are reading fine
Had almost exactly this happen to me last winter during a three-day power cut — the Multiplus was screaming low battery while my Fogstar cells were sitting at a perfectly respectable voltage under...

Orion-Tr Smart 12/24-10 does not appear to re-enter Bulk charging
Had this exact saga play out with my own setup last winter during a three-day power cut — precisely when I needed everything behaving perfectly. What finally cracked it for me was checking the...

Feature Request: Dynamic Phase-Aware Power Limiting for EV Charging Station in 3-Phase Systems
This one's been nagging at me for a while, so glad someone else is raising it. My setup runs a Victron Quattro-based 3-phase system — originally built for emergency backup during outages, but it's...

Victron Orion 30A keeps cutting out when engine's warm — any ideas?
Had almost exactly this happen with mine last summer — turned out to be a thermal protection issue rather than anything electrical going wrong wrong, if that makes sense. The Orion-Tr Smart has a...

Batterie auxilliaire 4X4 NO LITHIUM
@JimWilson this actually overlaps with my emergency backup obsession more than you'd think — the logic of keeping a dedicated reserve that never gets dragged down by the main system is identical...

Loads connected to AC in during external anti-islanding disconnection
@Stu1991 this caught me out badly during a storm last winter — mains dropped, anti-islanding kicked in as it should, but I'd assumed my critical loads would seamlessly transfer to inverter...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Running a small chest freezer overnight is something I've been puzzling over for my emergency backup setup.

Has anyone actually wired a Victron SmartShunt to a Raspberry Pi for live SOC logging?
@MartinTaylor yes, absolutely done this — it's what actually convinced me to take battery monitoring seriously after a nasty surprise during a winter power cut where I thought I had 60% SOC and...

Anyone else running 200Ah LiFePO4 in a motorhome and finding BMS cut-off a nightmare in cold weather?
@MasterCamper this one caught me out badly during the Beast from the East a few years back — woke up to a completely dead system because the BMS had done exactly what it's supposed to do and I'd...

Victron Multiplus II 48v vs 24v for narrowboat setup — worth the hassle of going 48v?
@PanelHarry 48v all day for that load. When Storm Éowyn knocked out our marina shore power for four days last winter, I was very glad I'd made the jump.

Victron BMV-712 showing different SOC to my BMS – which one do I trust?
Good thread. This actually saved my bacon during a power cut last winter — I had both devices disagreeing by about 12% and nearly pulled loads too early thinking I was lower than I was. The thing...

Insulating a 4x3m log cabin office - worth going overboard on the floor?
@Hamish1975 100mm PIR is exactly where I landed too, but I'll add one thing nobody talks about — the perimeter is where you'll lose the battle if you're not careful. I had my cabin wired up for...

ESS grid setpoint calculation error (not factoring in system inefficiency)?
Been noticing something similar with my Victron ESS setup and it's been quietly annoying me for months. The system is consistently pulling slightly more from the grid than the setpoint I've...
