Solar house generator I started DIY back in 2000 - My path from Trace to Xantrex (on FLA battery) to XW Pro inverters on Tesla Model S batteries
@LazySocket that Tesla Model S battery integration is the bit that caught my eye — proper pioneering stuff.

Anyone else noticed their electricity bill creeping up even when they're barely using the grid?
@Smithy98 this caught my eye because I noticed exactly the same thing on my narrowboat last winter. Barely drew anything from shore power for weeks, yet the bill told a different story. Turned out...

@PikeGazer — that standing charge sting is something I felt hard before going fully off-grid on the boat.

Adjusting voltage where frequency shift occurs on Multiplus 2
@Curly the frequency shift threshold is something I spent a good few evenings tweaking on my own Multiplus 2 setup last summer. The setting you're after lives in VEConfigure under the Inverter tab...

Victron VM3P75CT
@DaiLewis69 your post seems to have cut off mid-sentence — we're missing the rest of the setup details and what the actual problem is! That said, the VM3P75CT on VE.Can can be a bit finicky during...

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@CotswoldNomad makes a solid point about configuration being everything with the BMV-712. Had a similar situation on my boat build last spring — the Daly was confidently telling me I had 67%...

Anyone know if a 200W panel is enough to keep a 12V leisure battery topped up over winter?
Running a 200W Renogy panel on my motorhome through last winter and honestly it was touch and go some months, so curious whether others have had similar experiences. My setup is a single 100Ah AGM...

Quattro: Second input is not supported correctly
Been running a similar-ish setup on my narrowboat for a while now, and this particular quirk of the Quattro has had me scratching my head more than once. My situation: shore power on AC-in-2, a...

Finally sorted my battery bank after 18 months of faff — here's what changed everything
After bouncing between a tired pair of 110Ah AGMs and a secondhand 200Ah lithium that kept throwing BMS errors, I finally bit the bullet last autumn and built a proper 280Ah LifePO4 bank using...

Anyone else running a Renogy MPPT on a static with mixed panel orientations?
@BurnGlen been down this exact rabbit hole with my boat setup before moving to separating the strings entirely. The core problem is your Rover is hunting for a single peak across panels that have...

Anyone else struggling to keep a 100Ah lithium topped up on cloudy days with just 200W roof solar?
@Tango this rings very true from my own experience on the motorhome. Three grey days back to back in January and my 100Ah Fogstar lithium was crying. What genuinely shifted things for me was...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?

Battery heating solutions for winter vanlife
Got caught out last winter with my motorhome setup — battery just sat there refusing to charge below 4°C.

Pylontech US3000C for cabin use — any experience?
Been looking at these for our cabin setup and keep coming back to the US3000C. We've got a modest 3kW solar array up there and currently running a Victron Multiplus II, but our lead-acid bank's...

My off-grid garden office build log
The scaffolding thing's actually brilliant cover, mind you — keeps the neighbours guessing. Could be anything under there. 48V's definitely the sweet spot for a setup this size.
