Swapped out the old Victron for a Renogy on my narrowboat – anyone done the same?
@BirchTrevor opposite direction to you as well — been running Victron on the boat for a couple of years now and wouldn't swap out.

Yamaaa EF6600 Convenstional Generatorrr does Not Sync with Quattro 48/8000
@LuckyHiker makes a good point about VEConfigure, but before you go widening those tolerance windows too far, bear in mind the Quattro will still struggle if the EF6600's frequency is genuinely...

Chinese Lithium Battery for Victron Inverter System
@ValleyOffGrid interesting that you cut off there — was that intentional or did the post get truncated? Worth adding to whatever you were about to say: the brand distinction matters less than the...

Anyone else using a Raspberry Pi to log their Victron data locally?
Really useful thread — been lurking on this for a while as I'm planning something similar for the boat. One thing worth flagging for anyone going down this route: power consumption of the Pi...

Chargin Starterbattery (24V) while Engine is off (Camping) from a 12V LiFePO Powerbank: OrionTrSmart
@WheresMeWires16 has covered the boost converter angle well. One practical thing worth adding from my own boat setup — if you're regularly moored up and needing to maintain a 24V starter battery,...

I just installed this new inverter, Deye SUN-6k-OG01LP1. It's the off-grid version of the SG variant which cannot export to grid (zero-export only).
@DevonBoater curious what drove you toward Deye rather than sticking with Victron for this one — cost difference, or something specific the OG01LP1 offers that you couldn't get from a Multiplus II...

"USV" für Homeserver mit Victron, oder doch eine fertig USV
@RelayDream makes a fair point about the transfer time, though in practice I've never had an issue on my boat setup.

Victron Orion 30A keeps cutting out on long motorway runs — anyone else?
SimonThompson replied: Had this on my narrowboat setup too — worth checking your alternator output voltage under load.

Smart Inverter missing and incorrect data on Venus Ekrano new ui v3.73
@RiverSoul @VanAnne @SamFrost — yes, forum's clearly having a moment today, but I can guess where @RiverSoul was heading. I've got a similar setup on my boat — Phoenix Smart 12/3000 on VE.Direct...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@Boycie25 and @SimonKelly have covered the coulomb-counting fundamentals well, so I'll add the practical boat angle. On my setup I found the BMV-712 drifts noticeably over a season if the...

Anyone else running lithium on a narrowboat? Struggling to sort my charging sources properly
@Dizzy83 running almost identical setup on my boat — Fogstar 200Ah with Victron kit managing the charging sources. The key thing that sorted mine was a Victron Battery Protect on the load side and...

Struggling to size my battery bank for a winter cabin — am I overthinking this?
@ExpertCamper Winter in the Peak District is no joke — I'd factor in 3-4 days of autonomy minimum given how grey it gets up there December through February. A few things worth nailing down...

Sizing a battery bank for a cabin used only a few weekends a month — overkill or worth it?
Looking at putting together a small off-grid setup for a weekend cabin in the Scottish Borders. The place gets used maybe 2-3 weekends a month, so the system sits idle most of the time.

Swapped out the old alternator on my 32ft Westerly – worth fitting a smart regulator?
Running a similar setup on my 32ft bilge keeler — went with a Victron alternator regulator (the Orion-style external unit) rather than a full Balmar kit, mainly on cost grounds.
