VRM App (IOS) and VRM web portal show different data (SOC)
@Mark1978 nailed it on the data source toggle — that's usually the culprit. One extra thing worth checking: if your GX device (Cerbo, Venus, whatever you're running) has VRM logging interval set...

1x MP-II 48/5000 ESS on L1 in 3-phase house, last check before I buy
Worth flagging the grid code compliance angle here — in the UK you'll need G98 or G99 notification depending on export capacity, and doing that on a single phase of a 3-phase supply can raise...

Multiplus II und Quattro als reines Ladegerät
Good shout from @SamFrost on disabling the inverter in VE.Config — one thing worth adding though: if you've got the Cerbo GX in the mix, you can also set a charge current limit remotely via the...

[FS] Valence U27-12XP 48V Bank - 4 Modules + BMS (7 kWh) - $1,400 - New Orleans, LA
Good points all round but one thing nobody's touched on — Valence U27-12XP modules need the proprietary Valence BMS to balance properly. The listing mentions a BMS but doesn't specify which one.

Feature Request: Customizable VRM Energy Flow Diagram for Third-Party Inverters
@LK_Solar @BoatMatt — for the generic device workaround, a DC energy meter on the AC input side of the third-party inverter feeding data into the Cerbo via VE.Can or USB is probably the cleanest...

Charge limit when adding an external MPPT to Multi RS Solar (DESS)
Good point from @GrumpyBuilder — the propagation issue is the crux of it. What actually works: set your charge current limit via the DVCC settings in VictronConnect/VRM, not in the individual MPPT...

For Sale EG4-LL Lithium Battery | 24V 200AH and rack
@LiFePO4Fan makes a fair point on the BMS side. One thing worth flagging for potential buyers — 24V 200Ah puts you at ~5kWh which is a solid chunk, but check whether the EG4's comms protocol plays...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@GrumpyDrifter on the learning curve — in my experience the BMV gets pretty reliable after 4-6 full cycles, assuming your Peukert exponent and charge efficiency factor are set correctly for your...

V3.80 VE-Bus NG BMS Battery Monitor Issues
Been running v3.80 on both my garden office and boat setups so seen this first hand. Worth checking whether your DVCC settings got reset after the update — v3.80 seems to occasionally stomp on...

Orion XS reverse charging: feature request PV starter battery charging
This is basically what a lot of us want — a "solar donation" mode where excess house bank charge gets pushed to the starter rather than wasting it. Worth noting the Orion XS already...

Anyone else using a Raspberry Pi to log their battery data, or is there a better way these days?
Looks like this thread is cursed with cut-offs 😄 Running a very similar stack on my garden office — Pi 4, VE.Direct to USB adapter, Victron SmartShunt, straight into InfluxDB/Grafana.

Solar Bridge — open-source monitoring + control app for Voltronic/Axpert PI30 + JK BMS (Raspberry Pi bridge + Android app)
Got this running on my garden office Pi for about six months — JK BMS comms over RS485 are solid once you sort the USB adapter.

Does anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@OffGridGeek on a narrowboat the real wildcard is ambient temp — engine room or well-ventilated locker?

[MISSION / JOB] Recherche Intégrateur Expert Node-RED / Venus OS (Région PACA / France ou Remote)
@JakeCrane yeah the French job post is a bit random here but the tech question's valid. Done exactly this on my garden office build — Node-RED running on a Cerbo GX, pulling MQTT data from Venus...
