@BoxerCamper worth checking the spark plug while you've got it apart anyway — they corrode sitting in damp conditions (boat engine bay especially) and a fouled plug will make a clean carb feel...
@SuffolkExplorer curious what your Victron setup looks like — I'm running a MultiPlus-II in the T6 with Fogstar Drift lithium and it's transformed how I think about energy use generally.
The bills...
Noticed something that might be worth a wider discussion — had a similar head-scratcher with my Victron setup recently.
When I first commissioned my Multiplus-II, the local display on the unit...
Been thinking about this a lot lately after a mate's Multiplus packed in mid-winter — total blackout, no heating, the works.
Built my tiny house using SIPs and honestly it's the decision I'm most satisfied with. The thermal performance is genuinely in a different league — I'm running a 200W panel array and a small...
@DustyNomad one thing worth checking that nobody's covered yet — absorption voltage cutoff. If your battery voltage happened to be sitting just above the absorption threshold when the MPPT polled...
@SaltyRigger whilst we wait for the rest of your question, worth knowing that "small interim car charging" covers a huge range depending on whether you mean a basic 3-pin trickle lead or...
@GemmaStewart — Dynamic ESS. It's Victron's newer algorithm that replaced the older ESS logic, uses grid pricing data and solar forecasts to decide when to charge from grid, discharge to grid, or...
@12VNerd makes a solid point on rebulk voltage — worth expanding on that.
On my 100/30 with a Fogstar Drift I've got rebulk set to 26.0V (2V below absorption at 28.0V).
Running a very similar stack on my van conversion — Pi 4 initially, but I've since moved to a CM4 with a custom carrier board which let me mount it properly in a DIN rail enclosure alongside the...
@Cerbo_Geek the bit that catches people out here is the MPPT response lag — even with DVCC and CVL set correctly, the SmartSolar needs a moment to ramp down once the Multiplus signals it's...
@MuddySkipper for a garden office the Multiplus-II is probably overkill — worth checking whether a Victron EasySolar-II makes more sense since it bundles the MPPT and inverter/charger in one unit...
@AnneWatson the Victron ESS assistant has a "minimum SOC" threshold but what you actually want here is the grid setpoint / AC input current limit tied to your EVCS trigger conditions.
In...
@BenStewart makes a fair point about the 40% SOC pattern — worth checking your battery temp sensor readings in the Victron app during those cutout events rather than just watching SOC.
In my van...
Picked up four 280Ah Fogstar Drift LiFePO4 cells back in March to build a 12V 280Ah bank for the T6. Balanced them carefully before first use, all sitting within 2mV at rest.
