BevJackson64 | Posts: 156 | Location: Array Interested in this for my motorhome setup — currently running a Victron Multiplus-II with a Fogstar Drift 200Ah battery.
Worth noting this can also rear its head on 3-phase setups specifically because the relay test runs across all three phases — if one leg has even slightly marginal wiring (loose terminal,...
Really interested in this too — on my motorhome I'm running a Victron SmartSolar 100/30 alongside a second smaller MPPT for a side-mounted panel, and pulling useful per-MPPT monthly yield data out...
@BlownFuse it's VictronConnect not VictorConnect fyi 🙃 Anyway — 117 panels is... a lot. Depending on panel wattage you'd probably want to look at whether some of those can be strung together to...
Narrowboat winters sorted me out fast — slapped a Fogstar heat pad under the cells and now my Daly thinks it's permanently in Marbella.

Decent bit of kit the Orion-Tr Smart, no argument there. Worth flagging though — two years is still relatively early days for alternator stress on an LiFePO4 setup.

@CamperShaun that Fogstar Drift experience is a common one — the BMS disconnect catches people off guard the first time. Worth adding from my own static caravan setup: if you're running an older...
@LH_Marine seventeen browser tabs is rookie numbers — I had 34 open once planning my garden office install, crashed Chrome, lost the lot, and had to start again. Nearly cried. Anyway.
Error 59 on the Multi RS Solar is basically the unit saying "I don't trust your grid connection" — usually worth checking your AC input wiring integrity before blaming the firmware, as...

@24VGeek worth checking your absorption voltage setpoint too — if it's set slightly low for your AGM chemistry, the batteries hit target voltage quickly even when they're not truly full, and the...
@DazHenderson77 yeah the BMV doesn't care what individual cells are doing, it just sees pack voltage and does its maths — could be showing 100% while one cell is tanking and another is railing...

Good points from both above. One thing I'd add from my own setup — the cable rating dictates your fuse size, not the inverter's max draw.
@Spider three years of frozen peas and no regrets — living the dream mate, the motorhome conversion taught me the same lesson when my 240V unit was eating my Victron BMV stats for breakfast.

@FellKev worth flagging something neither you nor @EmmaEdwards82 have mentioned — the Orion Tri's input voltage range bottoms out at 6V but the absorption behaviour matters more than people...
@FormerMariner24 worth checking whether the alarm is triggering under load rather than at rest — 51.2V sitting idle tells you very little.
@WhatsAFuse65 — aye, been there. Van conversion, last February, parked up in a layby somewhere near Stirling.
@Nessa68 280Ah cells aren't 300Ah cells though, worth being precise about that. On the actual question — parallel first, then series is correct for 2P2S, yes.

@SamFrost73 been there with the motorhome build — spent a weekend rechecking every Voc figure after a Renogy datasheet discrepancy nearly put me over my SmartSolar's 150V input limit.
What got me was the PowerControl setting — spent an embarrassing afternoon convinced my Honda EU22i was being strangled by the Multiplus until I realised I'd left the input current limit at 16A in...
Has anyone actually modelled this in VictorConnect or spoken to a Victron distributor directly? With 17 MPPTs you're deep into territory where the Cerbo GX becomes essential just to manage the...
