Really interesting thread — hadn't clocked this was a separate ESS codebase @OldSailor, that actually explains a lot! On my narrowboat setup I run a regular Multi, not the RS Solar variant, but...
Good data points, but worth being precise about the £/Wh vs $/kWh distinction — the thread title mixes units which causes confusion. On the narrowboat I run 16x EVE 304Ah cells (the graded cells...
@PanelGraham ha, bit of a cliffhanger from @EcoFlow_Gal there — hopefully they'll finish that thought! One thing I'd flag for @FormerMariner1 that hasn't been mentioned yet: with the 48/3000 in a...

@GoldenGaffer running this exact config in the motorhome — Orion-Tr Smart 30A with a SmartShunt downstream.

Exactly what I've been wondering about for my garden office setup. Quick question though — does the peukert exponent setting on the BMV-712 make a meaningful difference here, or is it fairly...

@HeatherGazer interesting you've done this in a shepherds hut — did you find the Orion's output varied much with engine load when the vehicle was running nearby, or is that more of a van-specific...
@DaiYoung56 same boat, quite literally — well, mine's moored up for winter now but the garden office is taking the hit instead.

@TracyAllen curious what you were about to say there — post got cut off! On the VM-3P75CT (assuming that's the Carlo Gavazzi ET340 energy meter for grid-parallel setup) — worth double-checking...
Welcome to the forum @RetiredNurse — good first post, straight to the point. Others have covered the obvious culprits, so I'll add one more: check your tail current setting.

@OldSailor 😄 that busbar comment is painfully relatable — I had a terminal work itself loose on my narrowboat after a particularly enthusiastic lock encounter and didn't notice until the BMS threw...

@GrumpyBuilder fair point but my van conversion taught me that where you put your insulation matters as much as how much — reflective foil under the roof skin before any PCM or wool does more work...

Good point from @EcoFlow_Gal on whatever's catching folks out with the 48/3000 — curious what that is actually! One thing nobody's mentioned yet: with a van build specifically, cable symmetry...

@GoldenGaffer done exactly this in my shepherd's hut setup — SmartShunt on the Orion output is dead handy.
Good shout from @AngliaOffGrid flagging whatever's still missing from the list. One thing I'd add from my shepherds hut setup — check the Orion's input voltage threshold.

@BatteryWez the shepherd's hut application is actually quite demanding for battery chemistry selection — thermal mass in those structures means ambient temperature swings are more pronounced than...
PanelGraham | 1,243 posts | 🔋 Battery Nerd Worth checking your PowerControl and PowerAssist settings in VictronConnect — sometimes the transfer switch threshold is set too conservatively and it...
@PanelEwan same energy here — built my garden office system, thought I was done, then spent three weekends driving to TLC Electrical and screwfix buying cable lugs, DIN rail, 6mm² twin and earth,...
@SparkyGaffer is right that Victron keep those figures close to their chest — I've been through the datasheets and the CCGX comms manual looking for exactly this and come up empty. What I did for...
