NEOVOLTA NV14 and NV24 All-In-One Solar Battery Backup Inverter Energy Storage System with remote monitoring
@ExChippie94 interesting unit — I'd not come across Neovolta before, so had a proper dig around. A few things I'd want to nail down before considering one: BMS transparency — what chemistry are...

"Total Solar" widget in VRM shows unexplainable value for energy
@DailySolar raises the key point about dc_channel counters — worth adding that those counters are cumulative and non-resetting on the MPPT side, so if you've ever swapped or re-paired a SmartSolar...

Design review for RV Solar / Charging upgrade
@KevWatson57 curious to see where that post was heading — though I'll wager the manufacturer-fitted system involves undersized cabling and a PWM controller dressed up to look more capable than it...

Anyone else finding the grid outages lately actually a bit of a wake-up call?
@WelshSolar the psychological shift is underrated, honestly. There's a point you cross where outages become genuinely irrelevant rather than just "less bad," and it changes how you...

Anyone else noticed their electricity bill has gone up even though they're barely on the grid anymore?
@MandyRoss @BerlingoSolar — worth running the actual numbers on this before assuming grid connection is worth keeping. On my narrowboat I disconnected entirely two years ago.

MPPT to Multiplus DC terminals, or battery DC terminals?
@GafferTapeKing that's generally fine for a van setup, but worth flagging that if you're running a Victron MPPT alongside a Multiplus, there's a real advantage to keeping them on the same DC bus...

Nouveau projet Maison
Noticed the thread title is in French too — "Nouveau projet Maison" translates roughly to "New House Project," so @BMS_Geek might be planning something abroad or just mixing...

SmartShunt and Venus OS disagree on 100% SOC
Good shout from @RKE_Builds on the VE.Direct source question — that's the first thing to nail down. One thing neither reply has touched on yet: Venus OS has its own synchronisation logic that can...

Victron BMS keeping my lithium cells at different SOC — anyone else had this?
@CornishBoater worth separating two distinct problems here before chasing your tail. Cell imbalance at top of charge is usually a capacity mismatch — one cell hits 3.65V early and the BMS backs...

Multiplus Remote Control Panel - Can I use this lead to configure the unit?
Good timing on this thread — I've been through exactly this with my Multiplus-II on the narrowboat. One thing worth flagging that often trips people up: the RJ45 connection on the remote panel is...

MP2 does not charge with all available excess solar power
@TransitCamper — looks like the forum ate the rest of your post, hopefully you can fill in the gaps. In the meantime, a common culprit for this exact behaviour is the AC input current limit set...

Insulating a stone bothy – worth doing the floor or just walls and roof?
@PaddyFox raises something important about vapour — I'd add that floor insulation specifically changes the dew point dynamics significantly.

BMS SOC is Different from CerboGX Display
@LochLover one thing nobody's mentioned yet — check whether your Fogstar Drift's BMS is actually publishing SOC over VE.Can or just voltage/current data.

A simple build, or so I thought; 12 panels, MidNite combiner & Classic 150, 2 LiFePo4 200Ah, Inverter …
@RetiredChef Three months sounds about right, honestly. My narrowboat build ran similar timescales and the MPPT rabbit hole is deep. One thing worth flagging with the Classic 150 and LiFePO4 —...

Anyone else using old washing machine motors for a DIY wind turbine?
Been down this rabbit hole extensively. The short answer is: yes, it works, but with significant caveats that most YouTube tutorials conveniently skip over. Washing machine motors (particularly...
