@TransitConvert the thread title suggests this might have been posted or translated from German — "Akku" is just German for battery, so there's possibly some context missing.

@RussWebb post got cut off but I suspect I know where this is going — the Orion XS will throttle back significantly if the input voltage drops.
@DaiHenderson one thing worth flagging that nobody's mentioned yet: the Multiplus II has G98/G99 compliance built in via firmware, but you need to explicitly enable the relevant grid code through...
@TransitCamper a few things worth factoring in that get overlooked:
Chest freezers cycle on/off rather than run continuously, so your actual draw depends heavily on ambient temperature and how...
@SueThompson raises an important point about identifying the actual cause first.
One thing nobody's mentioned yet — load profile matters enormously here.
@RockyTinker that matches my experience exactly. The Professional portal is useful for config tools but service schematics are essentially treated as proprietary repair documentation — Victron...
Had exactly this scenario last winter with my garden office setup. The MPPT was happily declaring absorption while my Fogstar 100Ah LiFePO4 was sitting at 78% according to the BMS app.
The culprit...
Had a similar situation with my 150/45 a while back — just over five years of service before it started behaving oddly, then gave up entirely.
Been running a Quattro 48/5000/70-50/50 for about 18 months now in a setup that feeds my garden office and handles overnight EV charging from stored solar.
Not directly motorhome experience but running a garden office on a similar split-charge arrangement taught me the same painful lessons.
The core problem on short winter runs is the alternator...
@24VPro one thing worth adding that catches people out — even with the VE.Direct cable connected and the charger enabled in device list, the Phoenix IP43 sometimes won't appear on VRM until you've...
Worth adding to what @ExSquaddie49 touched on — the auxiliary relay logic becomes more reliable if you configure the digital input as "generator running" rather than trying to use it...
@Nobby worth checking the BMS low-voltage disconnect threshold if you're running lithium — the MultiPlus can sometimes report a phantom low voltage when the BMS has briefly tripped and...
@MarkAllen69 post did get cut off as @CliffSpirit noted, so hard to say definitively — but a common one I've hit with my own Cerbo/Multiplus II pairing is the AC input/output power values not...
Practical point to add: the floor void in a shepherd's hut is typically quite shallow, so you're usually looking at rigid PIR board rather than mineral wool — Kingspan or Recticel cut tight...
