Made the switch to lithium on my Sprinter last spring and honestly it's night and day compared to the AGM I'd been nursing along for three years.
Been messing around with something similar on my Cerbo GX for a while now — trying to build a half-decent charging schedule for two EVs without just hammering Octopus Agile prices manually every...
@MarineOllie dark evenings absolutely expose bad wiring and undersized capacity — no argument there.
@MikeCross the fix nobody mentions: drop your SmartShunt charged voltage threshold to about 0.2V below whatever your BMS terminates at.
Had something similar with a cheap battery I picked up — unlabelled symbol, zero mention of it anywhere in the (frankly useless) translated-from-Chinese manual.
@PaddyGibson what's the actual question? You cut off mid-sentence.
That said, if you're going down the Pi + Grafana route for a tiny house, just be aware the Pi itself needs a reliable 5V supply —...
Been running a similar setup for two years now. One thing neither of you have mentioned — SD card failure. Lost three months of logging data when my card died last winter.
@MarineGeoff fair point on the surge test, though I'd argue a router or table saw is nastier still.
Been running a SUMRY 3000W on 24V for about eight months now — mostly EV charging via a Type 2...
@VDH_Boats has a point about the Combox but nobody's mentioned the actual gotcha here — the Ekrano's RV-C implementation is read-heavy and the Southwire transfer switch expects certain PGNs to be...
@Nessa68 six months is nothing — I wasted the better part of a year on comms nonsense with my Pace BMS before I just accepted that the documentation is basically aspirational fiction.
One thing...
Depends entirely on what you actually got rather than what the seller claimed you got.
Facebook Marketplace solar panels are a lottery.
@DucatoDream is right, but worth adding — that indicator will also stay dark if your fuse is blown, even if voltage is present elsewhere in the system.
@CharlieStevens85 had this exact headache with my Multiplus II and a bank of Fogstar Drift cells. Once @PennineNomad's tail current fix is sorted, check your absorption voltage too — if it's set...
@ShortCircuit 200Ah for a garden office through a British winter was always going to be marginal at best.

@Rob1963 that "enthusiastically redistribute" comment made me laugh despite myself — seen similar.
