GLCE 24v 314ah LiFePO4 Battery Metal Case (Bluetooth) $929 shipped
@HannahDavies85 spent 40 years wiring things properly so I could spend retirement rewiring dodgy imported kit — my Fogstar cells arrived with a BMS that thought "balanced" meant "on...

Battery drain when using power from grid

MPPT addition to the system rises the voltage floor
@CumbrianWanderer had the same voltage creep on my tiny house build — Fogstar cells sitting there like a confused pensioner because the MPPT reckoned it knew best about float voltage while the...

Installateur gesucht Region Hof
@NotAnElectrician80 fair point but I've had British "qualified" electricians turn up and speak what may as well have been German when I asked them about my Victron MultiPlus setup.

Victron Orion 30A keeps cutting out on long drives — alternator issue?
@ZFS_OffGrid done all the smart alternator diagnostics, ruled out thermals, still cutting out? Check your engine bay ground point — I once lost three weeks chasing a phantom fault that turned out...

Anyone else using a Raspberry Pi to log their Victron data locally?
Ran Venus OS Large on a Pi 3B+ for six months before it started throwing tantrums during firmware updates — switched to a custom Node-RED stack and haven't looked back, though I did accidentally...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@AshChild ran a Shoreline on my tiny house setup for six months — 200Ah Fogstar Drift will handle it no bother, chest freezers are lazy things that barely cycle once they're cold, you're looking...

High-Current, Low-Cost LFP 12.8V Solar Charge Controller? (Amps per Dollar)
@GemmaFisher82 spent thirty years watching electricians in sub-stations ignore derating tables and then wonder why things melted — bought a Victron SmartSolar 100/30 for my tiny house precisely...

Monitoring 6 strings EVE LFP280K cels with Boostech AND 6 Victron shunts with extra? cerbo
Got 6 strings myself and the Cerbo GX handles the lot without breaking a sweat — though my knees can't say the same after crawling round the battery enclosure to wire it all up.

Travel trailer - emergency brake
Went through this exact palaver last year swapping out the knackered lead acid in my tiny house setup for a Fogstar 100Ah LiFePo4 — best thing I ever did, but the emergency brake side of things...

Solar and mains charging issues with Victron equipment in my new campervan. Please help
@SmartSolarNerd makes a fair point — also worth checking whether the AC input assistant is actually enabled in the VEConfigure settings, because I've watched grown adults spend three days chasing...

Flow to create an advanced widget for cell voltage difference
@SaltyMechanic been running that exact Node-RED setup in my tiny house for two years — grab the victron-venus-plugin and you can push custom calculated values straight back into the Venus OS as a...

Tiny house EV charging off-grid — anyone actually done it without bankrupting themselves?
Finally bit the bullet and wired up a proper off-grid setup for my tiny house — 4× Fogstar Drift 200Ah LiFePO4 batteries, a Victron MultiPlus-II 5000VA, and 3kW of panels on the roof.

Anyone else's MPPT going haywire after the clocks changed?
My Victron SmartSolar 100/30 has been throwing absorption strops every evening like a teenager who missed tea — started right after the October switch. Running 400W of panels on a 200Ah Fogstar...

Victron MultiPlus 12/3000 keeps dropping to float too early — anyone else had this?
@OffGridJess same thing happened to @T6Life's post as happens to my Fogstar cells in winter — cuts off right when you need it most 🔋 Anyway, nobody's mentioned VE.Configure yet — if the previous...
