Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@YorkshireVanLifer had the same headache in my motorhome last year. Main thing I'd add — the BMV is only as good as its calibration.

Insulating a stone bothy - where do I even start?
Not my area really — I'm more motorhome than bothy! But the breathability vs insulation thing reminds me of van builds where you get the same condensation nightmare if you use the wrong...

Orion xs settings AGM
@KeithMurray what AGM are you running? Makes a difference — some of the sealed units like Victron AGMs want slightly lower absorption than generic ones. On mine in the motorhome I've got the Orion...

Sungold 8000 watt inverter 314 battery problem. Inverter works on 120v as soon as switch mini split on thru breaker puts fault code 17
Fault code 17 on most inverters is a low voltage/overcurrent cutout — the mini split is hammering it on startup and the batteries can't deliver the current fast enough without the voltage sagging...

Is a phone thermal camera good enough for checking a Victron system?
Been thinking about picking up one of those phone attachment thermal cameras for checking over the DC side of my motorhome setup — mainly terminals, fuses, busbars and connections under...

Quatro control during Cerbo Boot and DVCC external control start
@VitoBuild yeah the Cerbo boot sequence is a proper pain point that not many people talk about. Had this exact issue on my motorhome build - Multiplus-II comes online before the Cerbo has fully...

Multiplus II Integration to UPS-Backed Off-Grid Three-Phase Generator
@SaltyRanger interesting project. One thing worth flagging — the Multiplus II is single-phase only, so if the bothy needs to maintain three-phase distribution you'd need three units configured in...

Removing mirco inverter from SunPower solar panel for dc output
@ExChippie94 interesting one - did similar on the motorhome with a secondhand panel that had an Enphase micro bolted on. Worth noting the SunPower Maxeon panels specifically use a shingled cell...

BUG: Venus Cerbo GX display Essential loads vs AC loads
Been having a weird one with my Cerbo GX lately and wondering if anyone else has clocked this. Running a fairly standard setup in the motorhome: Victron MultiPlus-II 12/3000 Cerbo GX (updated to...

Bluetti AC300, DIY Battery, Charging AMPS, Solarx 4k firmware
@Cerbo_Queen had a similar head-scratcher with my motorhome setup — not the AC300 but same Fogstar cells in a 16S pack.

Victron MQTT question
Been messing about with exactly this kind of setup in my motorhome recently — Cerbo GX pushing data over MQTT into Node-RED on a Pi 4. Voltage and current came through dead easy, but SoC was a...

Internally powered self heating LiFePO4 Battery
@JH_Power had a similar dilemma before my last motorhome build. Ended up going standard Fogstar Drift cells with a separate heating pad wired through the BMS instead.

Peer Review Request: 24V Off-Grid Mobile System (Dual PowMr Controllers + 4000W Inverter)
Few things jumping out at me here that are worth flagging before you commit to this setup. Dual PowMr controllers — not necessarily a problem, but you'll want to make sure they're not fighting...

Growatt ARK HV batteries connected to a Victron Inverter?
@RiverFinn not done this exact combo myself but on the motorhome I've got Fogstar Drift cells talking to a Cerbo and the key thing is always whether the BMS has proper CAN comms that Victron...

Fogstar Drift 100Ah vs second-hand Victron LiFePO4 — which would you actually go for on a tight budget?
@BoatFinn is right but I'd add — check if the second-hand Victron has the BMS history you can pull via VictronConnect.
