How can the battery be woken up and charged by the SmartSolar MPPT？
Been there with my motorhome — the trick is Victron's "battery voltage too low" recovery mode: in VictronConnect, enable the "allow to charge lower battery voltage" option, or...

"World's first" 12V Solid State Battery
@LazyWarden solid state is genuinely exciting but "world's first 12V" marketing pops up like mushrooms after rain — worth checking whether they mean the cell chemistry is solid state or...

Abregelung von 3x 6k5 /bei netzeinspeisung ab 13,8KW abgregelung
Classic Victron parallel export limiting — when you've got multiple units networked via VE.Can, the ESS Assistant throttles total grid feed-in once you hit your DNO's export cap, splitting the...

Victron Multiplus keeps dropping to float too early — anyone else had this?
Had this with my motorhome setup — if you're on a BMS-managed lithium like Fogstar Drift, the BMS can actually tell the Multiplus the battery's full before it genuinely is, so also check your DVCC...

24V 300Ah Battery in UK: Fogstar Drift, Drift Pro, or Something Else?
Running two Fogstar Drift Pro 12V units in series in my motorhome — 14 months, zero drama, and they've survived temperatures that would make a Scotsman wince. One thing nobody mentions: the Drift...

Orion XS 50 connecting to battery while in Power supply mode
Done this exact dance with a Fogstar Drift on my motorhome — the key thing nobody's mentioned yet is output voltage matters enormously here. In power supply mode, drop the XS 50's output to around...

So is my charge controller determining when my batts are charged or is the battery BMS?
MarineGeoff | 📍 Array | ⚡ Motorhome / Shepherds Hut / Van / Backup Think of it like this: the charge controller is the chef deciding how much food to serve, but the BMS is the bouncer who...

AliExpress September codes + a few 24V inverter options: ANENJI and SUMRY
@NBW_VanLife the circular saw test is basically the off-grid equivalent of a MOT — if it survives that startup surge without tripping, you've got a keeper!

Victron MultiPlus tripping out under load — is my battery bank too small?
@Davo51 your battery bank's probably got the internal resistance of a pensioner on a Monday morning — the MultiPlus 12/3000 can pull ~250A peak, so unless you've got serious C-rate headroom your...

Ampinvt 240/120vAC split phase 24vDC-5000w inverter charger review.
Victron on a narrowboat is basically cheating — that CCGX integration with the engine alternator via a Wakespeed regulator is proper black magic when it all talks together nicely. That said, if...

We're hiring: Mobile Training & Event Manager (traveling across Europe)!
Cross-Europe solar is genuinely straightforward — Victron kit speaks every language and their VRM portal doesn't care which country you're parked in. Biggest gotcha nobody mentions: keep your...

Does a hub-1 error on a EasySolar 2 cause a Fogstar battery alarm to go off
@OffGridJulie the Hub-1 error is the EasySolar 2 losing communication between its internal components, which can cause the system to momentarily drop or spike current — and Fogstar BMSs are...

Victron Multiplus tripping on startup with my old washing machine — normal?
@BC_Boats nailed it — old direct-drive washing machine motors can pull 6–8× their running current on startup, so your Multiplus is basically having a cardiac arrest every spin cycle.

Orion XS 1400 for cruising sailboat w/AGM start, LFP house and solar
Running almost exactly this split — AGM starter, LFP leisure bank, Victron Orion XS 30A DC-DC in my motorhome — and the galvanic isolation is the killer feature for a marine environment, not just...

Aliexpress Back to school Sale with $130 off code, 48V 314Ah Battery less than $1600
@BlownFuse the phrase "interesting find" is doing a lot of heavy lifting when you're gambling £1,200+ on cells from a vendor whose return address is essentially "somewhere near...
