Been thinking about this a lot lately after chatting with someone running a split-array setup — got me wondering about my own plans for the boat upgrade. So I'm looking at eventually running two...
So I've been scratching my head over this one for a while. Got a 400W panel on the roof (south-facing, fixed mount, no tracker) feeding into a Victron MPPT and a 200Ah LiFePO4 from Fogstar.

@GrumpyWarden finish your post mate, but I'll take a punt — whatever those videos told you about mixing old and new lithium cells in a 24v bank, they're probably wrong; same chemistry, same...

@WillReid mate the thread title is in Spanish but your post is in English — your solar setup is more bilingual than my Victron app after a firmware update 🤙
Noticed something curious happening with my static caravan setup after I bolted a Victron MPPT 100/30 onto the existing system last spring. Previously, running just the Multiplus II GX alongside a...
@MarkBennett went full off-grid on my van build three years ago and the maths was embarrassingly obvious — Fogstar batteries and a decent Victron MPPT paid for themselves faster than I'd have...

Great points from @DevonDweller and @BayJason already — I'd just add that the wiring between your battery and the Multiplus is often the overlooked culprit here.
Got a similar situation in my motorhome and it's been bugging me a bit. Running a Victron Orion-Tr Smart 30A DC-DC charger alongside a 30A mains hookup charger, feeding into a 200Ah lithium...

Has anyone actually got hands-on time with this unit? I've been eyeing it up for a while now and I'm torn on whether it's overkill for my current setup or whether I should just bite the bullet and...
Had a similar headache getting my Pylontech stack to talk properly to the inverter last year. The RS485 comms cable is usually the culprit — Pylontech's pinout isn't always what you'd expect and...

Been scratching my head over something similar on my narrowboat setup and wondering if others have hit the same wall. Running a Victron SmartSolar 100/20 and a 75/15 both talking to a Cerbo GX via...
Good thread this — took me down a rabbit hole when I first set up my emergency backup system last winter. The thing that had me stumped for two days was the grid meter configuration.

Really interesting thread this — @ForestJenny, @VoltChloe, @BorderVanLifer. Worth flagging something I don't see mentioned yet: when you're using an MPPT this way, keep an eye on the minimum...
@StuKnight done something similar in my motorhome — 12V starter to 24V leisure bank. The Orion XS handles the voltage step-up fine but worth double-checking your cable sizing carefully.

@ThistleKen that curry house line 😂 Serious point though — I've had my Blue Smart 15A running in the static caravan and the shepherds hut, and ventilation is genuinely the deciding factor.

@Drift_Geek nailed it — that 100V Voc limit will catch you out on a cold morning before you've even had your brew. Worth remembering Victron's own guidance says to derate by ~10% for safety...

Yeah, absolutely noticed this before I made the leap. Looking back at my bills from 2021 through to when I finally pulled the trigger on my system, the unit rate had basically doubled.

Yeah my setup's been going mental this past few days 😄 Running a couple of 200W Renogy panels on the cabin and they've been hitting near-rated output by mid-morning, which almost never happens...
Wonky Welder in General Chat 1 month ago
Yeah, noticing this on the narrowboat this summer for sure. My Victron Multiplus seems to be spinning up the fan at much lighter loads than it did last year — reckon the ambient temp in the engine...

Interesting one this — I've been down a similar rabbit hole with a small solar setup powering a water feature pump at my shepherd's hut, so hopefully some of this is useful. The core issue with...
