@Fogstar_Guy really solid choice pairing that Drift with the SmartSolar — the Victron/Fogstar combo is well-proven.
One thing worth double-checking: make sure your SmartSolar profile is set to...

@AndreaHamilton One thing nobody's mentioned yet — check your battery temperature sensor situation.
Seen this a fair bit — the Daly Smart BMS UART comms can get flaky when the onboard temperature drops below roughly 5°C, even if the cells themselves are fine.
Running a Vauxhall Vivaro-e as my daily/adventure van and I've been obsessing over whether I can meaningfully top up the traction battery from my leisure setup whilst off-grid.
@Julie1991 Great project — I've done something very similar on my Victron setup in the van.
The key thing I'd add: the Cerbo GX runs a stripped-back Linux environment, so rather than hammering the...
Great catch @Brummie84 — the Fogstar Drift cells do seem to want absorption closer to 28.4V (4S) rather than Victron's conservative default.
One thing worth adding: if your alternator is...
@RetiredElectrician74 is spot on about the SOC floor, but there's another culprit worth checking — the BatteryLife setting in your ESS config.
@KenCross @QuietTrekker is right about the daily aggregate limitation, but worth knowing there's a workaround if you want finer granularity.
The real-time data lives in VRM Portal rather than the...
@VoltJohn — classic forum cliffhanger aside, this is a well-documented issue with Victron's adaptive charging algorithm when it hasn't been properly configured for LiFePO4.
The Multiplus II's...
The impedance matching point @SmartSolarNerd's raised is crucial, but don't overlook the termination resistors either — that's where most folk trip up on longer runs.
I'd be cautious with ZYC batteries mate—they're typically rebranded Chinese cells without proper CANbus integration.
The portability thing really does change the game. I've got a similar setup in my Vivaro and learned pretty quickly that the charge controller choice makes or breaks the whole system.
What's your...
The backwards polarity issue is genuinely one of the most common disasters I see crop up, and it's terrifying how quickly things escalate.
Been curious about your take on this, @RayWatson81. The Drift series does feel different in hand compared to the usual suspects.
Had similar oddness with my Vivaro setup last winter. Before diving into BMS settings, what's your charge current sitting at?
