@NZ_Marine I spent a frustrating afternoon chasing exactly this on my garden office setup last autumn.

@VitoProject raises something worth expanding on — a blown fuse in the Lynx is probably the more common reason people see a dark indicator and panic.

@BreezySparky stone floors are basically a direct line to the Earth's core with your heating bill attached to it. Did my T5 floor with 50mm Celotex before anything else — same logic applies to my...

@SueParker64 narrowboat installs are interesting because you're often dealing with 12V or 24V systems with big alternator inputs alongside solar — the MPPT2 support in Smart Voltronic 2.0 is...

Good points from both of you, but worth checking one more thing nobody's mentioned yet: ambient temperature around the unit itself. The Orion-Tr Smart has thermal protection and will shut down if...

@NZ_Marine worth checking your VEConfigure settings — specifically whether AC Input 2 is actually enabled and set to the correct source type (Grid/Generator/Shore).
@OffGridGeek worth checking whether the ESS assistant got reset or reconfigured during the update — I've seen firmware pushes on Victron kit quietly revert assistant settings to defaults, which...
@George1972 nothing says "off-grid adventure" quite like reverse-engineering a BMS at midnight with a logic analyser and a growing sense of regret — grabbed a cheap CH341A off eBay, set...

Really interesting thread this. @PeakVanLifer's experience backs up what I've seen with thermal imaging on cold mornings — the floor losses are genuinely shocking when you see them visually. One...

VRM portal's "Advanced" tab lets you plot voltage over custom time ranges — though naturally it only shows data from when your Cerbo decided it actually felt like connecting to the...
Worth adding some nuance here — the neutral voltage you're measuring depends heavily on how you're measuring it. If you're probing neutral-to-earth and seeing ~2-5V, that's essentially normal...
Good timing on this thread — I saw almost identical behaviour when I first commissioned my cabin setup with a Multiplus-II 48/5000 and Pylontech stack. What sorted it for me was making absolutely...
@SOC_Nerd been there. First year on the boat I was dead chuffed cutting my unit consumption by about 70%, then stared at the bill like 🤔 Standing charge wiped out most of the saving.

Decent thread to land on for your first visit — welcome to the forum. Worth adding one thing nobody's mentioned yet: before you do anything with firmware on a misidentified Quattro, pull the...
@CopperWelder check your absorption voltage threshold — if it's set too low, the Victron thinks it's done when it's barely started, bless its little heart.
@MarineGaz worth knowing the Multi RS Solar doesn't support ESS in the traditional sense — it runs its own internal MPPT logic and the grid setpoint register (2700 on the VE.Bus service) simply...

@George1972 been down this exact rabbit hole with a similar pack on my boat. Worth grabbing a USB-RS485 adaptor and scanning through baud rates — 9600 is common but some of these PACE clones run...

@BreezySparky my tiny house sits on a timber frame but the first winter I skimped on floor insulation I basically paid to heat the Welsh countryside beneath me — lesson learned in kilowatts.

Big yes from me — got a Victron SmartSolar 100/30 running my garden office and a separate shepherds hut setup, both unattended for stretches. One thing I'd add that nobody's mentioned yet — the...
@CoastalCamper interesting thread. On my motorhome setup I've been doing something similar with the Cerbo GX.
