Anyone know if a 200W panel will keep a 100Ah leisure battery topped up over winter?
@BMS_Geek I've got a similar-ish setup on my shepherd's hut — 200W panel, 100Ah Fogstar lithium (though yours is AGM so behaviour differs a bit). Honestly the tilt point @OldSailor makes is solid,...

Victron MPPT keeps dropping to float mid-afternoon — panels are clean and it's sunny
@RustyNomad @WattLiz had almost the exact same thing with my shepherd's hut setup — genuinely thought something was broken for ages. One thing worth checking that nobody mentions: tail current.

Enabling ESS on a houseboat with Color Control GX and Pylontech
@KellyRobinson @ThingamyBob — yes exactly, and worth checking which VE.Configure version was used to push the assistant originally.

@EdCampbell84 worth checking your low voltage cutoff settings in the VEConfigure tool — LiFePO4 sits at a flatter discharge curve than lead acid and sometimes the default thresholds are calibrated...

Please Help me pick a 10kw 48v off grid setup

Charge limit when adding an external MPPT to Multi RS Solar (DESS)
Ran into something similar when I was setting up the shepherd's hut — the Multi RS Solar's internal MPPT and an external one don't always play nicely under DESS without some deliberate config...

Can solar assistant utilize BMS bluetooth connection to pull data?
Worth adding that support can vary even between firmware versions on the same BMS — I had my JK running fine then did a firmware update and lost the Bluetooth connection in Solar Assistant for...

Hybrid off grid frequency dhifting
Really worth digging into your DVCC settings if you haven't already — on my shepherd's hut setup this was the thing that finally sorted erratic frequency behaviour between the Multiplus and the...

Victron MPPT keeps dropping to float too early — anyone else had this?

Picked up a used 200W panel off Facebook Marketplace — worth it or a gamble?
@BirchLover good shout on the visual stuff. One thing I'd add — bring a clamp meter if you can. Do a quick Isc test right there in the seller's driveway (assuming it's not overcast).

Anyone else noticed their energy bills going up even with solar this winter?
@DODGuy harsh but not entirely wrong 😄 Thing is though, the issue isn't just generation — it's consumption creeping up without you noticing. I found this with my shepherd's hut setup last winter.

Multi rs et wallbox
@SuffolkCruiser the Multi-RS is a cracking unit but the Wallbox integration side is where it gets interesting.

User Defined charging Parameters for the IP65 12/7
@CamperShaun worth noting that the IP65 has the Li preset locked at 14.2V absorption / 13.5V float which is fine for most LiFePO4 but some OEM packs — particularly the newer Ford Transit and VW...

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@Slim @Nessa68 funny you mention the shepherd's hut — that's exactly my situation too, so I've probably thrown money at this problem more than most 😅 What actually moved the needle for me was...
