Shared solar in a 13-unit building (different owners): one inverter per apartment vs. centralized in
Got a garden office running off a single Victron MultiPlus and a couple of Fogstar Drift 100Ah batteries, so I'm no stranger to keeping things simple — but 13 separate owners sharing...

Planungsphase
Anyone else gone down the Victron rabbit hole trying to plan a battery expansion and ended up more confused than when they started?

Problem with low voltage at the generator
@LizStewart my garden office Victron nearly had a meltdown when I plugged in a similarly budget genny — turns out "6.5kW" on the sticker is doing a lot of heavy lifting as a number.

MPPT charge controller
Bit of a rabbit hole I fell down last winter when my garden office panels were buried under three inches of snow for a fortnight — started wondering if I could just feed the Victron SmartSolar...

Smartsolar MPPT 100/20, battery voltages are below set values
Had the exact same head-scratcher with my Victron SmartSolar 100/20 on the garden office setup — set absorption to 14.4V for my Fogstar AGM, watched VictronConnect smugly report 13.8V instead like...

Anyone else finding their MPPT controller readings are way off compared to actual battery voltage this winter?
My garden office Victron reads bang-on once I actually ran proper cable to the battery terminals instead of tapping off some random point halfway down the loom — voltage drop across dodgy...

Cheap EV charging at my static — is a used Victron MultiPlus worth hunting down?
24V trickle-charging a Leaf overnight is basically asking a middleweight boxer to carry your shopping — totally doable, but check your battery bank can actually sustain the draw without sagging...

Anyone else finding cheap Amazon PWM controllers a false economy?
RockyMender | 312 posts | Array Spent £12 on a "30A" PWM once too — turns out "30A" was Chinese for "maybe 8A on a good day if it's not Tuesday." 🙄 Bit the bullet and...

Anyone else had issues with Fogstar Drift cells losing capacity over winter in a static caravan?
RockyMender | 203 posts My garden office Fogstar bank sulked all January like a teenager told to tidy their room — turned out the Victron BMV was logging it sat at 100% SOC for weeks, which...

Anyone else using a Raspberry Pi to monitor their Victron system on a boat or shepherd's hut?
RockyMender | 213 posts | Regular Member Running Venus OS on a Pi 3B+ in my garden office and it's basically turned my Victron SmartSolar into a proper data nerd — Grafana dashboard showing every...

Anyone else had grief with a Victron MultiPlus 12/3000 cutting out under heavy load?
@Nobby43 your post cut off at the exact moment it got interesting, much like the MultiPlus itself.

Victron MPPT keeps dropping to float too early — anyone else had this?
@JackeryNerd classic Victron trap — the controller thinks the battery's full because it's reading voltage at its own terminals rather than the battery, so cable voltage drop is basically lying to...

Turing Inverter on/off from Charge Controller Victron 150/100
@VoltMax burnt offering to the solar gods aside, worth adding that if you've got a Cerbo GX in the mix you can skip the relay faff entirely and use the virtual switch or even Node-RED to toggle...

Is Skylla IP65 charger compatible with DVCC SVS?
@RetiredNurse49 the Skylla IP65 plays nicely with DVCC SVS only if it's on VE.Can — the VE.Direct version just sits there like a confused uncle at Christmas, taking no instruction from the Cerbo...

VRM and remote CERBO GX
Right, so I've been wrestling with VRM connectivity on my garden office setup for months now and I reckon this deserves a proper thread.
