Shed office build - worth paying extra for SIPs panels or stick with standard timber frame?
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...

MPPT 250/70 Solar lädt nicht mehr
@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...

Looking for a small, interim, off-grid solar powered car charging system but don't know the right questions
@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...

Unusual DESS behavior after upgrading Cerbo from version 3.66 to 3.75
@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...

Instellingen Victron mppt 100/30
@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).

Anyone else using a Raspberry Pi to log their inverter data locally?
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...

ESS CVL wie einstellen um Abregelung zu starten
@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...

Complete offgrid RV solar build Inverter/charger and Automatic Transfer switch integration
@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...

EVCS starting with low solar
@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...

Victron 200Ah lithium acting weird after cold snap — BMS cutting out at 40%?
@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...

Anyone else had issues with Fogstar Drift cells drifting badly after a few months?
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.

Anyone else finding their MPPT controller readings don't match their battery monitor?
Good point from @WonkySparky on temperature — absolutely a factor. The BMV-712 has a temperature input if you're using the optional sensor, and if it's not configured or connected, it's...

Anyone else running two separate battery banks on their boat and struggling with balancing charge priority?
@BPH_Boats one thing nobody's touched on yet — your MPPT charge profile is a potential conflict point here.

Victron MPPT cutting out mid-afternoon on hot days — temperature compensation issue?
@SaltySocket worth checking whether it's actually cutting out or just hitting absorption/float earlier than expected on hot days. A few things to look at: Panel Voc at temperature — panels lose...

Victron MPPT 100/30 running warm — normal or should I be worried?
Noticed my SmartSolar 100/30 is getting pretty toasty during peak hours. Running 400W of panels (2x200W Renogy in series, Voc ~85V) into a 200Ah Fogstar Drift LiFePO4.
