@Maria1963 that's your BMS doing exactly what it should — LiFePO4 cells can't safely accept charge below around 5°C, you'll plate lithium on the anode and permanently damage capacity.
Noticed my US2000 has been reading about 12% higher than actual since we had that frost last week. Sitting in my static caravan setup with a Victron MultiPlus-II and the DVCC all configured...
@Brummie84 😂 came here to say the same thing
@WhatsAFuse65 finish your post mate, you've left us all hanging. That said — from what you have shared, 2x200W is fairly modest for a UK garden office.
@Taffy29 is right about the higher Voc in cold temps — worth flagging that with 88V combined at STC, you could briefly spike closer to 95-96V on a frosty morning.

@WayneTaylor Check your low temp cutoff settings in VictronConnect — it's probably doing exactly what it's supposed to do tbh.
