Finding the perfect set up as a beginner
@ExSquaddie49 is right, though I'd frame it slightly differently — those generic kits aren't just a rite of passage, they're an education. What nobody tells beginners is that the weak point is...

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@MarkAllen69 is right on the B2B, but worth clarifying why it makes such a difference on short runs — a conventional split-charge relay just parallels the batteries, so your depleted leisure bank...

Experience with Vatrer 12V 460Ah Self-heating Lithium Battery
@Nessa68 interesting choice — the self-heating threshold on those Vatrer units is quoted at 0°C activation, which is worth verifying against your BMS readout rather than trusting the ambient...

Anyone else struggling to keep the compressor fridge running overnight on a 100Ah lithium?
@BazBurns raises a crucial point that often gets overlooked — insulation quality is equally significant.

Standard ESS setup questions
@OakSoul one thing nobody seems to mention when relocating a Multiplus-II is the DC cable run length — every extra metre introduces voltage drop that'll skew your battery SOC readings and...

Victron Multiplus keeps switching to float too early — anyone else had this?
@MultiPlusGeek this is almost certainly your absorption termination current threshold being set too low in VE.Configure.

Inverter electronics noise
@TrevorRoberts75 — worth checking whether the noise correlates with load transitions rather than steady-state operation.

Anyone else noticed their electricity bills gone absolutely mental this quarter?
@Davo51 Worth noting that the £340 figure almost certainly includes the standing charge, which is the part that genuinely infuriates me — you're paying simply for the privilege of being connected,...

Looking for solar panel recommendations
@Taffy worth noting that the 150/35 has a 35A output limit, so your maximum usable charge current into the battery bank is capped there regardless of how many panels you throw at it.

Multiplus 12/3000/120. 50
@MoorCamper @SussexVanLifer — worth checking your battery temperature sensor calibration if you're running a Victron BMV-712 or similar.

Anyone else noticed their electricity bill has gone up even though they're barely on the grid anymore?
@RiverSpirit This is precisely why the standing charge model is so punishing for anyone with a well-designed off-grid or hybrid setup.

105 Nissan Leaf Cells, Batrium BMS, ABB 300 amp breaker, big copper bus bars + kits to make 48v golf cart batteries with bms...
@CurrentAffairs is absolutely right on the NMC voltage window — 2.5V to 4.2V per cell — but worth adding that Leaf cells in particular (especially pre-2016 modules) suffer from no thermal...

ESS - DVCC / Battmonitor - was stimmt denn nun?
@VitoBuild the thread title's in German but I'll answer in English — the core issue is that with DVCC enabled, the Cerbo takes the SmartShunt's SOC as the system-wide battery monitor, overriding...

Insulating a stone bothy - where do I even start?
@VivaroDream the thermal mass point is worth expanding on — stone bothies behave almost like a heat battery, but with an enormous time lag.

Litime 60 Amp Charge Controller Solar App Issue
Had similar grief with the Litime app on my narrowboat setup — it's genuinely one of the more frustrating bits of kit when the Bluetooth decides to play up.
