Had the exact same nonsense last winter with my cabin setup. Before you go down the tail current rabbit hole (already covered above), check your absorption voltage is actually set correctly for...
@EcoFlow_Master genuinely cannot believe you've left it there. Twice.
Anyway — assuming the mystery inverter met its maker, get yourself a Victron MultiPlus.
Done this exact thing at the cabin last spring — ran the induction hob and tried to top up the Leaf simultaneously.
@Deano had this exact faff with my cabin setup last year. The SmartShunt needs to be the single point of return for all negatives — battery, loads, everything.
@PeteJames done exactly this at the cabin. Pi Zero W → SmartShunt → InfluxDB/Grafana pipeline. Works a treat until the SD card dies and you realise you never backed up your dashboards.
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.
