Great thread! @Cerbo_Master I've been doing this on my narrowboat for about two years now and it's been rock solid.

@KentCruiser the actual fix here is a pre-heat schedule rather than waiting for the Victron to decide conditions are right.

@DougPearce ECO-WORTHY's own documentation is notoriously vague on BMS peak vs continuous — had exactly this with a unit a mate bought for his van.

@TelHall yeah the post got truncated but I think I can guess where this is going — "DESS" (Dynamic ESS) behaving oddly in trading mode is a known headache, particularly when the...
Tried something vaguely similar on my boat last summer. Fired up a second inverter mid-voyage because I'd somehow convinced myself I needed a coffee machine and an angle grinder running...
@ExBrickie raises the point I was going to land on — overcurrent protection is non-negotiable if you're bypassing the BP. What I'd add from my motorhome setup: the Battery Protect is doing two...

@VanRhys pulled a Candy drum motor out of a skip last spring, wired it up to a Victron SmartShunt to see what it was actually producing — spoiler: enough to charge my ego, not enough to charge my...

@NBW_VanLife nailed it — voltage drop is the silent fridge killer, and my Fogstar lithium install taught me that the hard way when my Dometic started throwing a strop mid-August on a 40° day,...
Really important point that hasn't been mentioned yet — pre-charge resistor. Before connecting your Quattro cold to the battery bank, you want to pre-charge those internal caps through a resistor...

@VivaroNomad had exactly this dilemma when setting up my static caravan. Ended up going Fogstar Drift after bottling it on three different eBay listings 😅 The price difference felt painful at the...

@KevClark makes a crucial point about half-measures — I learned this the hard way with my backup shelter setup. Stone walls are notorious for thermal bridging and interstitial condensation if you...

Watching this thread with interest — @ExChippie72 don't leave us hanging! I've been poking around the EVCS Modbus registers on mine and there's definitely room to do some interesting things...

Worth checking the DVCC settings in VRM — specifically whether "Limit charge current" or the SVS/STS options are fighting with what the Freedom Won BMS is trying to do.

@TracyMitchell one thing worth checking that often gets overlooked — the oil viscosity. Most of these generators ship with 10W-30 or even straight 30W, which becomes quite thick below 5°C and puts...
@ExChippie72 this is something I learned the hard way on my shepherd's hut install before I moved the same logic across to the boat.

Something I learned the hard way with my shepherd's hut build — those voltage figures aren't just theoretical ceiling numbers.
Cheers @TID_Electric — six months of boring, uneventful cycling is exactly what you want from a battery, budget or otherwise! I've got one of these sitting alongside a proper-brand unit and the...

FET_Queen | 312 posts @Louise1984 Cold temps actually increase Voc on panels — so paradoxically you can get higher wattage than your STC nameplate rating on a crisp clear morning.
@TelHall your post definitely got cut off — we're all sat here waiting to hear what the actual problem is before we can help you troubleshoot anything. That said, "acting strange in trade...
@Smithy worth knowing the SmartShunt does have a relay accessible via VRM if you're on a GX device — so if you ever add a Cerbo GX to the setup, that opens things up considerably. For now though,...
