How to create master / slave configuration with multiple smartsolar mppt 250/100
Same setup on my garden office — two 250/100s via VE.Direct into a Cerbo GX and that's really where the magic happens.

High Volltage Alarm Pylontech
Been seeing a few threads about this lately and figured I'd chip in with my own situation. Running a Pylontech US3000C stack (3 units) in my garden office setup with a Victron Multiplus II.

4x 12V 280Ah or 1x 48V 100Ah help it make sense.
So I'm trying to wrap my head around battery bank configurations for my garden office build and the maths is melting my brain a bit. I've seen cheap 12V 280Ah LiFePO4 cells going for decent money...

NEOVOLTA NV14 and NV24 All-In-One Solar Battery Backup Inverter Energy Storage System with remote monitoring
Never heard of Neovolta before this thread. For a garden office setup I'd probably stick with something like a Victron Multiplus paired with a Fogstar battery — more local support if something...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Yeah both valid points tbh. The thing I'd add — calibration matters massively with the BMV-712. If your battery capacity figure is slightly off (and it usually is with Fogstar Drift cells that...

Victron Multiplus keeps throwing a low battery alarm but cells are reading fine
Had this exact same gremlin with my garden office setup last year. Turned out my battery voltage sense wires had a dodgy crimp — Multiplus was reading voltage at the inverter terminals rather than...

EG18KPV (formerly 6500s) 120/240 Setup, 48V 105kWh Battery & Overkill 100A BMS Install
Decent build! Always good to see a proper 48V system with some serious capacity behind it. 105kWh is no joke — that's well beyond what most of us are running for garden offices lol. Curious about...

solar to an existing victron battery?
Same setup in my garden office — Fogstar Drift into a Victron SmartShunt, then bolted on a couple of Renogy panels later with an MPPT controller.

Unable to set up new Paralell/Split Phase MultiPlus II system (Comp ID Issue)
@TransitProject @DODQueen — yes, this caught me out too. Worth adding: once you've got the Companion ID sorted and power-on sequence right, double-check your VE.Bus cable quality.

Single MultiPlus-II ESS in a 3-phase house with manual V2L backup
Ran into this exact headache planning my garden office setup. Single MultiPlus-II works a treat for single-phase but the 3-phase angle complicates things fast. One thing worth considering - if...

MPPT Charge Controller Over-voltage
Yeah @DustyHiker's right about the cold Voc spike — caught me out too with my garden office setup. Worth actually running the numbers before assuming you're safe.

18 month DIY project finally done: 39kW inverter power off grid system
@BurnGlen yeah the battery bank is the bit I'm dying to know about too. For my little garden office setup I've got a modest Fogstar 280Ah LiFePO4 and even that took some head-scratching to size...

Anyone else finding the Renogy 40A MPPT a bit temperamental in cold weather?
Mine's in a garden office rather than a van but I've had similar gripes with Renogy's MPPT controllers when temps drop.

Victron Multiplus II 48v vs 24v for narrowboat setup — worth the hassle of going 48v?
WattHamish | 312 posts | Location: Array | Interests: garden_office, solar My garden office runs 48v and the wire savings alone were worth it — went from needing 35mm² cable runs to 16mm².
