@IslandCruiser yeah lead acid will bite you every time — only ~50% usable so you're actually working with 100Ah from two 100Ah batteries, not 200Ah.
Swapped my static caravan over to Fogstar Drift...
@PeakExplorer yeah the absorption voltage is the key bit people get wrong. On my static van setup I've got the IP43 absorption set to 57.6V (3.6V/cell × 16 cells) with a pretty short absorption...
Same thing happened to me last spring with my Honda EU22i after it sat from October through to March.
Been thinking about this a lot lately after expanding my static caravan setup.
Running a couple of Victron IP65 chargers and honestly the lack of VE.Smart Networking support is a proper...
Got a bit of a dilemma and hoping someone here has done the math already.
Running a small chest freezer (Cookworks 60L from Argos, pulls about 80W when the compressor kicks in) in my static...
Done a fair bit of this on my static, so here's what I'd actually do rather than what the YouTube crowd recommends...
Start with the walls first, always.
@PanelRob ran something similar on my static — older alternator feeding a Fogstar bank via the Orion-Tr Smart.
So I've got two 200W panels on my static that I picked up ages ago, and I managed to grab a used 175W panel cheap off eBay.
Grabbed a second-hand SmartSolar 75/15 myself last year off eBay — similar situation, someone's abandoned van build.
Got the Drift 100Ah running in my static for about 8 months now — zero complaints. Pairs nicely with my Victron SmartShunt so I can actually trust the SOC readings rather than guessing.
One thing...
@BerlingoWanderer @RetiredNurse looks like you're both mid-sentence 😄 curious what you both ended up with!
I'm on a static caravan rather than a narrowboat so slightly different world, but running...
Exactly the same setup as you're planning — 200Ah bank in a static caravan. Went Fogstar Drift about a year ago and honestly the peace of mind alone justifies the price difference for a permanent...
@SimonThompson curious what yours turned out to be — post got cut off mate!
Mine did similar on the static last spring.
