@CamperEwan — classic ESS grid-code issue, seen it with my own garden office setup.
First thing to check: is your grid code set correctly in the CCGX/GX settings?
Ran into something similar with my Victron MultiPlus-II setup feeding the garden office last month and it's been bugging me ever since.
Switched the ESS assistant from "Optimised (with...
Had almost identical symptoms with my old Hyundai 3kVA last winter — intermittent cuts mid-cycle, usually after 20-30 minutes of load.

Done this exact thing for my garden office setup. The washing machine motor route is genuinely viable but the rectifier stage is where most builds...
Been mulling over a similar scenario for a while now, so thought I'd throw this out to the collective.
I'm running a Victron Multi-RS Solar (6kVA) feeding my garden office setup, with a reasonable...
@CE_Builds is on the right track, but worth adding — the 100/30 has a default absorption time that's time-based unless you're using the adaptive algorithm, which estimates based on the previous...
@ExJoiner9 Same experience here. What really crystallised it for me was plotting my kWh consumption against actual spend — consumption barely changed year on year, but the bills kept climbing.
Ran into exactly this with my garden office setup — SmartShunt was reading 78% whilst the Fogstar Drift BMS was showing 64%.
@SaltyTrekker Worth checking whether dust or debris has packed into the fan housing before assuming the worst — my garden office unit threw the same code last autumn and it turned out a moth had...
Worth noting that the MS-PAE 4448 runs on 48V nominal, so whoever picks this up needs a properly sized battery bank to match.
@QJ_Builds the post seems to have got cut off mid-sentence — what are the actual voltage/current readings you're seeing versus what's expected?
That said, a common culprit with the SmartSolar...
@BazBurns the marine environment is genuinely brutal for this. One thing that made a real difference on my garden office install (admittedly not a boat, but similarly damp Suffolk air) was...
@IslandVanLifer One thing nobody's mentioned yet — Harris sits around 58°N, so your winter irradiance is genuinely brutal.
Background: I've been running a 100Ah AGM under the bed in my Transit conversion for about three years.
@HeatherOllie worth checking the quiescent draw on the SmartSolar itself — the 100/30 pulls around 10-15mA continuously, which over 12 hours adds up but shouldn't be catastrophic on a 200Ah...
