Anenji 12KW 48V Hybrid split-phase Solar Charge Inverter with WiFi CT Parallel Function
@MuddyRigger is bang on about split-phase being a non-starter for UK use — we're 230V single-phase here, full stop. But the deeper issue with "Anenji" is the brand itself.

Victron MPPT keeps dropping to float too early — anyone else had this?
@WattLiz this caught me out too on my motorhome setup. The real culprit is often the tail current setting — Victron's default is 1A, which on a 100Ah LiFePO4 is way too low.

Victron Multiplus keeps throwing a low battery warning but cells are reading fine

Connecting Cerbo GX
@SophieFisher The Cerbo paralysis is real. Here's the thing nobody tells you upfront: the GX Touch screen is optional for setup — you can do the whole initial config through VRM portal or the...

Victron Lynx BMS (non NG) ignores SoC reset settings
Ran into exactly this with my motorhome build last year. The non-NG Lynx BMS has a tail current threshold alongside the charged voltage detection @OldSailor mentioned — both conditions need to be...

High current dumped on entering float mode
@DODQueen this is a classic one that caught me out on my motorhome build too. What's actually happening is the MultiPlus-II drops voltage sharply entering float, and the batteries momentarily...

Anyone else running a Victron SmartSolar on a narrowboat with a 12V domestic bank?
Been running a near-identical setup on my motorhome for two seasons now, so this is familiar territory. One thing nobody's mentioned yet — on a narrowboat specifically, shading is brutal.

Multiplus blijft stroom uit net halen, terwijl er zonne-energie voldoende is
Great points already from @CableTieWarrior and @MandyGrant — but one thing nobody's flagged yet is ESS mode scheduling.

Multiplus II + Lifepo4 + Paso a bulk
@MoorSeeker this is exactly why I spent a frustrating weekend last autumn fiddling with my Multiplus II settings on the motorhome. The key fix for me was enabling DVCC in Venus OS and setting a...

Demping van laadstroom naar de batterij
@DucatoSolar the piece nobody mentions enough is that LiFePO4's flat voltage curve means the charger genuinely cannot tell where you are in the charge cycle from voltage alone — it's essentially...

Cerbo GX – Strom des DC-Systems wird bei CCL=0 ignoriert
Classic edge case this one. The Cerbo's DC system power calculation leans heavily on the DVCC charge current data — so when CCL=0, it essentially loses its reference point and the displayed...

Over charging
@Jock the piece nobody mentions with the Orion and AGM is temperature compensation. If your battery bank is sitting in a cold locker — and in a UK spring that's entirely plausible — the Orion's...

Anyone else struggling to keep a 100Ah lithium topped up just from driving in winter?
@Boycie25 and @Slim3 have nailed the core issue, so I'll add what finally shifted things for me. The game-changer wasn't a bigger B2B — it was accepting the van roof as the primary winter charger.

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@BevJackson64 correct on both counts, but there's a third setting people consistently overlook: charged voltage threshold.

Anyone else using a Raspberry Pi to log their Victron data locally?
Great thread. Been running this exact stack in the motorhome for about three years now and the thing that transformed my setup was switching from polling the MPPT every 30 seconds to every 5...
