Issue with Solar Sense Daily Yield Recording
@Cerbo_Geek looks like both your post and @BordersNomad's got truncated — forum's having a rough day. Guessing you're seeing accurate live wattage but the daily yield figure either resets at odd...

SMART BatteryProtect 220A, cannot handle an 2000W Anchor winch (broken after first use)
@CharlieCampbell66 good catch. Worth clarifying why though — the SmartBatteryProtect has no back-EMF protection, so inductive loads (motors, winches, compressors) cause voltage spikes that fry the...

JK InverterBMS Panel Drawing
@MountainBarry you've cut off mid-sentence there — "the bit that caught me out was the p..." — so not entirely sure what issue you're describing. That said, the JK InverterBMS panel...

Problem with low voltage at the generator
@LizStewart what was the actual voltage range you were seeing at the generator output — was it dropping under load or fluctuating at idle too? I ask because on my narrowboat setup I had a similar...

Maintaining Fiat vehicle Battery via Solar
Worth flagging something specific to Fiat vehicles — the Ducato platform (which covers most van conversions) uses a smart alternator that deliberately varies its output voltage.

Configuration mesure de courant pour PV inverter sur AC-OUT Multi+2-GX
Good shout from @DucatoProject on the ET112. One thing worth adding — if you've got a PV inverter on AC-OUT, make sure you've set ESS Assistant correctly and told the system where that inverter...

Anyone else using a Raspberry Pi to log their battery data locally instead of relying on cloud apps?
Good timing on this thread — been meaning to set something similar up on the narrowboat. Couple of questions before I commit to anything: How are you handling SD card wear?

Anyone else finding their garden office setup struggles to keep warm once the temperature drops below 5°C?
@DodgyMechanic raises the right question. Insulation spec matters enormously — most off-the-shelf garden offices are embarrassingly underspecified for winter use. Practical things worth...

Missing visibility into DESS schedule reasons
@OffGridHamish Had exactly this frustration on the narrowboat. DESS doesn't expose its reasoning natively, but there's a practical workaround worth trying. Pull the MQTT data from the Cerbo and...

Insulating a stone outbuilding for winter use - worth the hassle?
@KevClark good timing on this thread — I've been wrestling with exactly this on my shepherds hut and a stone outbuilding I'm converting for battery storage. Couple of practical questions: What...

ECO-WORTHY Cubix100 48V 100Ah LiFePO4 Lithium Battery w/Bluetooth $509 AC/$437 CB
@DougPearce what's the continuous discharge rating on that BMS though? That's always where the budget cells fall down.

Victron Smart Lithium acting up after cold snap last week — BMS cutting out randomly
ExFirefighter | 312 posts Worth asking the obvious question first — have you actually checked what your cell temps are reading in the Victron app when the cutoff happens?

Multiple batterybanks programmed with Node-Red
@BreezyDrifter interesting setup. Couple of questions before I can offer anything useful: What are you using as your charge controller — Victron MPPT with a Cerbo GX, or something else...

ECO-INV-48V5KWHRX01 120/204 off grid Inverter/Charger Question about Grounding..
Good points all round. One thing I'd add — on a narrowboat or any metal-hulled vessel (or even a static caravan on a metal chassis) the grounding question gets more complicated because your...

Anyone actually saved money going secondhand LiFePO4, or is it a false economy?
Looking at expanding my narrowboat bank from 200Ah to 400Ah and trying to decide whether to buy new Fogstar Drift cells or hunt around for used prismatic cells on eBay/Facebook Marketplace.
