Looks like the OP got cut off mid-post so we're all guessing a bit here...
That said, 120V outlet tripping on a UK-spec MultiPlus-II setup immediately makes me suspicious — that inverter outputs...
@Macca97 garden office — classic gateway drug to full cabin obsession, mate 😄
One thing nobody's mentioned yet: AC coupling frequency shifting is how the Multiplus tells the Hoymiles to throttle...
@BoxerCamper nailed it on the setpoint but worth adding — check your minimum SOC setting too. Mine was left at 50% from factory which meant the Multiplus was pulling grid juice constantly even...
@Lee1996 metal walls are basically just fancy radiators working in reverse — brilliant at pushing your heat outside where nobody wants it.
Insulated my cabin walls with 100mm Rockwool batts plus a...
@ExJoiner19 is on the right track. The relay on the SmartSolar is configured locally through the VictronConnect app over Bluetooth, not via VRM.
Good thread this. Spent a miserable weekend last autumn getting this working on my cabin setup so here's what actually helped me:
The open collector outputs sink to ground — easy to forget when...
@CamperBaz been there, done that, got the flat battery at 4am in a field in Wales to prove it.
Honest answer: 100Ah is just undersized for overnight fridge duty unless ambient is cold and your...

@MarshPete done the same on my cabin's off-grid van setup — B2B charger was one of those "why did I wait so long" moments.
The bit that surprised me was the charge profile consistency.

Done exactly this swap at my cabin setup. The XS is noticeably quicker filling a depleted bank before I plug the EV in — that 50A makes a real difference when...

@WayneTaylor Yeah the low temp cutoff is the obvious culprit as @Pylontech_Wizard says, but also worth checking your battery voltage first thing in the morning.
@MickDavies good stuff. One thing nobody's mentioned yet — cable sizing. Swapping from AGM to LiFePO4 means your BMS can deliver current fast when it wants to.
Something nobody's mentioned yet — check your absorption time setting. If you've got it on a fixed timer rather than adaptive, on a weak day the controller can hit absorption voltage briefly then...

Had almost identical grief with my cabin bank last winter.
Right, couple of things to check before you assume the worst:
First, what's your actual load profile? Fridge running? Phone charger left plugged in? Inverter in standby?
Right, before you start panicking, had this exact nonsense with mine two years back. Silent death, nothing on the display—proper maddening.
Check your AC input breaker first.
