Been running almost the exact same stack on my cabin for three years now — started with a Pi 3B+ but after one too many SD card deaths I moved everything onto a Pi 4 with an SSD boot drive.
@ExFarmer90 done exactly this in my motorhome. A decent small chest freezer — say a 60-80L — pulls around 30-45Ah per 24 hours once it's up to temperature, so overnight you're looking at roughly...
Good timing on this thread — I saw almost identical behaviour when I first commissioned my cabin setup with a Multiplus-II 48/5000 and Pylontech stack.
What sorted it for me was making absolutely...
@OldSailor75 good point about the pairing — but trolling motor draws are a different beast entirely compared to motorhome loads.
The spike current when you first throttle up can be brutal.
@VivaroWanderer don't leave us hanging on that one mate 😄
@JimWilson I had almost exactly this on my cabin setup two winters ago — generator feeding a Multiplus 2 through a long cable run, and it...
@ThingamyBob the rabbit hole is real, mate. I went down it myself when I was sorting my cabin setup.
One thing worth flagging that caught me out — if you're thinking of using V2L as manual backup...
@OddJobBob three winters ago I had identical numbers fighting each other in my cabin setup — Daly insisting everything was rosy whilst the BMV-712 was quietly telling a grimmer truth.
Here's what...
@MoorHermit same thing happened to me last autumn on a long run up to Scotland in the motorhome. Took me ages to track down.
In my case it was thermal cutout — the Orion was mounted in a poorly...
@Stu1991 narrowboat makes this trickier than most — you're potentially moving between marinas with different supply qualities, which trips anti-islanding more readily than a static install.
Here's...
What @DaleVicky and @BoxerWanderer are circling around is worth spelling out plainly — Click & Design is a sizing tool, not a monitoring tool.
Right, so the elephant in the room nobody's finished saying yet — hybrid vehicle alternators, Toyota's included, do not behave like traditional alternators.
Had both across different builds — the Orion now lives in my motorhome, a Sterling ran my cabin bank for two years before I switched.
Honest take: the Sterling is bombproof and simpler to...

@GarySmith58 Been there. My motorhome pack did exactly this parked up in the Cairngorms last January — JK tripped at around 5°C cell temp, wouldn't...

@LuckyHiker while you sort that post out, I'll say this much — I ran a mismatched array on my cabin for two years.
@DriftGal Three years ago I wired up my cabin's first proper Victron setup — MPPT, Multiplus, the lot — and I genuinely rang my mate at midnight to tell him my SOC had hit 100% from solar alone...
