CraftyWanderer | 847 posts | Midlands @SmartSolar_Queen ah, the classic "battery says it's fine but the inverter disagrees" situation!
@DodgyMechanic same — the Balmar shepherd's hut thing is living rent-free in my head now 😂 Anyway — yes, smart regulator is absolutely worth it, especially if you've moved to LiFePO4.

SilverRanger | Posts: 847 | Location: Cumbria @LakelandExplorer Ha, the confused labrador description is painfully accurate 😄 Worth remembering that Discharging on VRM represents the DC-side...
Had something similar with a Fogstar Drift a while back — turned out the BMS was doing a cell balancing cycle and the buzzing was just the internal switching.

@ExBrickie raises something I learned the hard way with my cabin setup. Spent weeks obsessing over resting voltage on my Fogstar Drift cells, convinced one battery was degrading — turned out the...

Actually worth adding from my own experience with the EcoWorthy — the fan behaviour does seem to change over time.

@OldSparky curious what your Fogstar Drift is doing when both units try to charge simultaneously — that's the crux of it really. From my cabin setup, I found the key is letting the BMS be the...

Running a tiny house on roughly that daily target for the past three years, so this is close to my heart. Panels — I'd go 800W-1kW of solar minimum, even for 3kWh daily.
Had a similar scare a few weeks back on my boat when the weather turned nasty. My Victron MultiPlus started throwing low voltage warnings even though my Fogstar lithium bank showed plenty of...
Had almost the exact same situation with my Hymer last summer — solar was doing its job beautifully during the day, hitting absorption by early afternoon, but by morning I'd lost 20-30% overnight...
@StuCampbell makes a fair point about terminal protection, though I'd extend that to the entire monitoring side too — Victron's VRM portal is brilliant but a corroded RJ45 on your GX device will...
Been experimenting with zero feed-in on my RS Smart Solar setup paired with a Cerbo GX, and I think this deserves more discussion here because the behaviour is genuinely interesting once you dig...

@EwanChapman have you looked at the U-value of your glazing? I found my garden office was cooking despite decent wall insulation — turned out the single-glazed skylights were the main culprit,...

@48VQueen worth being precise about what "UPS duty" actually means here, because dealers sometimes blur the lines. The Multi RS Solar has a transfer time of around 20ms — that's not...
Has anyone actually got hands-on time with this one? I've been eyeing it up for my garden office build and the price point is genuinely tempting compared to what Fogstar or Pylontech are asking...
Had something similar with my Orion-Tr Smart 12/12-30 a while back — that particular buzzing/static sound is genuinely unsettling when you first hear it, especially because mine was doing it even...

Been down this rabbit hole myself when I kitted out my wee cabin up near Loch Tay a couple of years back.
Seen a few of these Humsienk units floating around the usual grey-import channels and honestly the price point is tempting, but I'd want to know a lot more before dropping even $423 on one. The...

Had this exact headache with my garden office setup last year. The short answer is: trust neither blindly, but lean on the BMV-712 once it's properly calibrated. Here's my thinking: Your BMS is...

@ExBrickie same boat situation here (literally). Cerbo GX was the piece that tied everything together for me. What I'd add — don't overlook the historical data side of VRM.
