Running this exact setup on both my garden office and boat — the Cerbo's Venus OS relay logic is solid but I'd add one thing nobody's mentioned: hysteresis.
If you trigger the non-essential shed...
@ThistleTel nailed the VE.Direct angle. One more thing worth checking — in VRM portal itself, go to Advanced and look at the device list.
Jumping in before we all overlap too much 😄
Since @LesWood78, @JA_Solar and @DownsCamper have likely covered the obvious suspects, I'll flag something that bit me on my garden office setup with a...
Had this on my garden office build last year. Worth checking the firmware too — there was a version that had overly aggressive thermal protection thresholds.
@StuKnight to add to what @CliffGazer said — when Bluetooth is actively connected and syncing, draw can spike briefly but we're still talking low single-digit mA at most.
Ha, cursed thread indeed @XO_Sparks 😄
Assuming @CamperSam is asking about Victron's Continue with Missing Phase setting on three-phase Multi/Quattro systems — yeah, it's genuinely...

Worth checking your absorption voltage threshold in VictronConnect — the Multiplus will exit bulk the moment it hits that voltage, regardless of time, if your battery...
Good points from @MaxYoung80 and @JubileeClipHero5 already.
One thing I'd add from my boat setup — watch out for the AC input current limit interaction.
@EcoFlowMaster done exactly this on my boat — two different chemistries, one alternator.
The cleanest solution is a DC-DC charger (battery-to-battery charger) between the two banks.
@OldSailor makes a great point about SD card rot — worth adding that you can boot Venus OS from a USB SSD instead, which completely sidesteps that issue.
Setting up a MultiPlus-II for my garden office build and trying to get my head around the parallel AC topology before I commit to wiring anything up.
My plan is:
MultiPlus-II 48/3000 as the...

Done exactly this on my garden office — mixed a 160W with two 200W panels on a Victron 100/20 for about 18 months now.

Good points from @TracyRobinson and @WattEd on usable capacity and chemistry. One thing I'd add — don't forget inverter surge draw.

Classic site hookup issue. Worth checking your AC input current limit is set correctly in VE.Configure, but also look at the PowerControl and PowerAssist settings — these are what actually manage...
@BurnSophie done this on my boat for about 18 months with a Leaf (30kWh). Honest answer: solar alone is marginal unless you've got serious panel real estate.
Key things I learned:
Charge to 80%...
