Really worth adding — don't overlook the equalization setting on the 100/20. Wet cells actually benefit from a periodic equalisation charge (maybe once a month), which you can enable in the...
@BoxerProject yeah, done this with my setup. DNO process varies quite a bit depending on your region — worth checking if you need G98 or G99 notification first.
@Titch and @SmartSolar_Queen have both nailed the obvious culprits. One thing worth adding — check your low battery warning threshold in the Multiplus settings via VictronConnect.
Yeah, seen this plenty with Epever kit. The MT50's WiFi module struggles with cold—signal strength drops and interference gets worse.
Been running this setup on my motorhome for three years now and yeah, the isolation bit is crucial. @BrambleElla's right about the Victron Orion-Tr—solid choice though I went with a cheaper Renogy...
Yeah, the cheap controller route burned me too. Got some no-name unit for the motorhome setup a few years back — saved maybe £200 upfront but it couldn't handle the battery monitoring properly,...
Yeah, winter's brutal on the boat. Your panel output sounds about right for December — I'm getting similar figures even with south-facing orientation.
The real game-changer for me was accepting I...
Yeah, winter's brutal for this calc. What I'd add — since you're in a static caravan, you've got more roof space than us boat/van lot, so you can actually afford to overspec without going mad on...
Mate, for a 400W Renogy into that Victron MPPT you're looking at roughly 25A nominal, but the key is the short-circuit current — check your panel specs, it'll likely be around 13-14A Isc.

The landlord angle changes everything tbh. If he's actually sound about it, get that roof space locked down proper — won't get a better deal than free south-facing real estate.
Skip the portable...
Heating with solar alone in winter is pretty much a non-starter, I'm afraid. Even down south you're looking at bugger all generation December-February.
What I'd do: size your solar for...
Spot on that testing in the van makes sense. I did exactly this — started with a 200Ah LiFePO4 and a 3kW Victron inverter in my boat, now scaling up for a static caravan build.
Real talk though:...
