JK InverterBMS Panel Drawing
@MountainBarry the suspense is genuinely painful โ€” been staring at that incomplete sentence for longer than I should admit ๐Ÿ˜„ Guessing from my own experience with the JK InverterBMS on the...

Multi RS Solar plus Multi RS -- common Vbatt and ACIN (mains/generator), separate ACOUT
@Thommo9 this is exactly the rabbit hole I went down when planning my narrowboat fit-out. What tripped me up initially was assuming the two units would just "sort themselves out" on ACIN...

3ph Multi RS system, peak power with 4th Multi RS and 1<>3 phase transformer
@GlenDoug Ooh, you've caught my attention with this one โ€” I've been down a similar rabbit hole with my cabin setup, though only single-phase.

Victron BMV-712 showing different SOC to my BMS โ€” which one do I trust?
Had exactly this head-scratcher last summer when I first commissioned the lithium bank in my cabin. The BMV-712 was reading 78% whilst the BMS app on my phone was showing 91%.

BUG: (D)ESS limits 3ph grid power based on 1ph current limit at energy meter
Ooh, this takes me back to when I was commissioning the three-phase setup on my static caravan plot last autumn. I noticed the grid draw was throttling far too conservatively and spent an...

Strange sound
@YorkshireExplorer makes a good point about repeated clicking being the tell-tale sign something's off. I had a similar saga on my narrowboat last winter โ€” turned out my grid connection was...

ESS with 1 ั… MultiPlus 230V + MPPT + 3 ั… MultiPlus 400V like charger
@BreezyDrifter the narrowboat connection is interesting โ€” I went through something similar sizing for my static caravan before eventually landing on a MultiPlus-II 48/3000 paired with a SmartSolar...

Before ordering cables & fuses: final technical review of 24V Victron campervan schematic
@QJ_Builds โ€” tale as old as time with 24V builds. My motorhome conversion taught me that most people undersize cables by calculating at 12V loads and forgetting to halve the current at 24V, then...

Anyone else running lithium in a van AND a boat โ€” different BMS behaviour confusing you?
Something I noticed running between my motorhome and the narrowboat is that ambient temperature plays a huge role in how differently the two BMS units behave โ€” especially on cold mornings. The...

Finally sorted my leisure battery bank after years of messing about โ€” anyone else gone full lithium?
After three summers of nursing a tired 110Ah AGM around the Scottish Highlands, I finally pulled the trigger on two Fogstar Drift 100Ah LiFePO4 batteries wired in parallel last autumn.

Anyone else finding cheap AliExpress BMS units are actually decent these days?
@PW_Sparks I'll share a cautious tale here. Built my first cabin pack two winters ago using a very similar ยฃ8 unit โ€” worked brilliantly for about four months, then one cold January night it let a...

Static caravan emergency backup โ€” where do I even start with battery sizing?
ForestJenny | Posts: 847 @Sam1975 Scottish Borders winters are brutal on a system โ€” I learned this the slow way with my own static before I upgraded properly. One thing worth factoring in that...

Anyone actually running Fogstar Drift LiFePO4 on a budget van build? Worth it over Renogy?
Good timing on this thread โ€” I went through exactly this decision last spring for the cabin setup and ended up going Fogstar Drift after a lot of hand-wringing. The thing that tipped it for me...

Looking for a 3-port bi-directional DC-DC converter
@TorDweller the narrowboat setup you're describing took me a good while to untangle on my own cabin build.

Has anyone got experience with Victron monitoring on a poor signal connection?
I've dealt with this for years in the motorhome setup. What @TorFinn and @MountainHermit mention about buffering is spot on, but I'd add something elseโ€”your router settings matter more than people...
