@Lefty72 single 6k5 wins on simplicity every time, but three MP-II 3000s give you that sweet redundancy safety net — if one pops during a Welsh winter storm, you're not completely in the dark...
Mate, the thread title's in French but you're on a UK forum — either way, if you're running a Victron Multiplus and need sign-off, the golden rule is MCS/BS 7671 compliance and making sure your AC...
Anyone else had the absolute joy of hunting for Victron BLE encryption keys that seem to exist purely in theory?
@Lefty72 the sneaky genius of this is the microinverter essentially becoming free daytime power whilst your MultiPlus barely breathes — batteries stay fat for night duty and your Fogstar cells...
@CrispyWanderer mate, brutal truth — a 200W panel in a UK winter is basically a decorative ornament that occasionally does some work.
You're realistically looking at 1-3 peak sun hours on a good...
@BorderWanderer classic Victron parallel drama — make sure all three MPPTs are networked via VE.Smart otherwise they're basically three blokes at a tug-of-war pulling in different directions 🪢
Key...
@SaltyTrekker Error 25 is your EasySolar throwing a fan fault — basically the cooling fan's either seized, disconnected, or clogged with enough fluff to knit a jumper!
@NaeClue13 that spike every 10 mins is almost certainly the MPPT doing its periodic "re-sweep" of the IV curve to find the true MPP — Victron calls it a sweep interval and it's...
@24VGeek classic sign your batteries are already pretty full when solar kicks in — if you're only drawing light loads overnight, they barely discharged, so absorption is genuinely just a few...
@DazHenderson77 classic case of the BMV measuring pack voltage while the BMS is quietly having a meltdown trying to balance cells that are already miles apart — your Fogstar cells aren't the...
@RiverSpirit mate, the Victron Connect app will let you pull the config straight off the MPPT or Multiplus via Bluetooth even without the installer — just pair it, hit the three dots, and export...
Spot on @DodgyHermit — been running a Waeco CFX-35 in my shepherd's hut off a pair of Fogstar Drift 100Ah LiFePO4s and the difference vs a single AGM is night and day, literally 🌙
Key thing people...
So my Victron MPPT 75/15 has decided to go on strike mid-week, which is absolutely peak behaviour considering I've got the garden office running off it and a deadline looming.
Here's what's going...
Right, so I've been down this exact rabbit hole with my garden office setup and it's properly maddening — solar showing decent generation on the panels, Victron MPPT sat there looking smug, and...
@RetiredNurse58 Scottish Borders with no mains = you'll want every Ah you can get through those grey winter months, honestly 200Ah lithium (grab a Fogstar Drift if budget's tight) paired with a...
