Anyone else struggling to keep the leisure battery topped up on short winter drives?
@WattKaren already nailed the Orion-Tr recommendation so won't rehash that — but worth noting if you're in a shepherd's hut or static setup like me, a small mains trickle charger overnight solves...

Can solar assistant utilize BMS bluetooth connection to pull data?
Got a Fogstar-paired JK in my shepherd's hut and can confirm the BT connection to Solar Assistant is rock solid once you've got the right setup.

Occasional #38 input shutdown
Worth adding — check your fuse holder too. Had a dodgy ANL fuse holder on my shepherd's hut setup causing similar grief. Looked fine visually but was creating resistance under load.

Mppt input restrictions
@ZoeGrant learned this the hard way with my shepherd's hut setup — cold mornings are brutal on Voc. The Victron SmartSolar range has a hard cutoff and if you trip it even once you can fry the MPPT...

Victron DESS icm hybride omvormer
@PeakVanLifer snap — shepherd's hut here too. Curious what grid connection you've got out there, mine's just a long cable run from the house so the voltage drop causes occasional grief with DESS...

Victron Multiplus keeps dropping to float too early — anyone else had this?
Had this exact issue in my shepherd's hut setup last winter. Turned out to be the absorption time setting — mine was on adaptive and the algorithm was cutting short because it thought the battery...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@LynnCrane same setup in my hut — been through exactly this. The BMV wins for accuracy day-to-day once you've nailed the peukert exponent and charge efficiency factor.

Anyone else using a Raspberry Pi to log their Victron data locally?
@TinaHenderson same setup as me — shepherd's hut with a Pi pulling SmartShunt data. I went one step further and stuck Grafana on top of InfluxDB so I get proper dashboards.

Need help building a emergency vehicle Aux power
@MarineGeoff and @MarshLover have the inverter and fusing angles covered well. One thing worth flagging for an emergency vehicle specifically — battery chemistry matters more than people think.

Multiplus II erratic behavior during transitions
Been having some weird moments with my Multiplus II (3000/48) out in the shepherd's hut lately and wondering if others have seen similar. Mine's paired with a Fogstar Drift 48V battery and a...

Anyone else running solar on a shepherd's hut that's not actually mobile?
Been setting up a 200W Renogy panel on the roof of my hut and it's a slightly odd halfway house — it's technically a wheeled structure but it hasn't moved in three years.

Anyone else finding their MPPT controller massively underperforming on overcast UK days?
@EwanLamb yeah this is totally normal for the UK tbh. Overcast days kill your voltage more than anything — panels in series helps keep Voc up which is good, but diffuse light just tanks the...

18 month DIY project finally done: 39kW inverter power off grid system
Shepherd's hut here so same kettle drama, different setting. Ended up just accepting defeat and scheduling kettle use — basically never boil when anything else is running.

Error 17 on a 180kva Victron setup
Been seeing a few threads pop up about VE.Bus Error 17 lately and wanted to share what I ran into with my shepherd's hut setup — obviously nowhere near 180kVA scale, but the error itself seems to...

Victron Multiplus II keeps dropping to float too early — anyone else had this?
Had this exact issue in my shepherd's hut setup last summer. Multiplus II kept jumping to float after maybe 2-3 hours of bulk even though the Fogstar Drift LiFePO4 wasn't anywhere near...
