@ForestDweller one thing specific to narrowboats that doesn't get mentioned enough — your alternator charging profile matters a lot.
@NorfolkVanLifer the weather forecast analogy is doing a lot of heavy lifting there but it's accurate enough.
The bit nobody reads in the ECO-WORTHY manual is the de-rating table.
@VickyWard one thing people miss with LiFePO4 and absorption — it's not like lead acid where you need a long absorption phase.
Been noticing something similar with my setup and can't decide if it's normal behaviour or worth worrying about.
Running a single-phase system here — Victron Multiplus-II 3000 with a 3-unit...
@Lefty28 makes a fair point — with the RS 450/200 you're pushing serious wattage and the firmware history on that unit is patchy.
@DucatoProject is right on the 360W ceiling, but there's a bit more nuance worth knowing.
The 100/30 input limit is right there in the name — 100V Voc max.
Running a small shepherd's hut in the Peak District and trying to work out if my setup is going to cope come November onwards.
Currently got a single 200W panel (Renogy) feeding into a Victron...
@DefenderAdventure already flagged the language thing so I'll leave that alone.
@NQ_Sparks — you've cut off mid-sentence so nobody actually knows what the problem is yet.
@BoatPaddy's analogy isn't wrong but it's not quite the full picture either.
Your panel's nominal voltage is almost irrelevant here — what matters is the panel's actual open-circuit voltage (Voc)...
@BarryWood worth checking your battery voltage sense wiring too — if the MPPT is only measuring at the controller terminals rather than at the battery itself, voltage drop across the cables fools...
Yeah this is the standard behaviour, and honestly it's correct — charging lithium below 0°C wrecks the cells long-term.
Been keeping an eye on these EU-stock SEPLOS builds for a while now. The EVE 314Ah cells are solid — Grade A from EVE is genuinely decent, not the lottery you get with some grey-market stuff.
Been down this rabbit hole myself when I kitted out my shepherd's hut a couple of years back, so thought I'd share some thoughts and get a discussion going.
The Victron MultiPlus-II is the obvious...
Been running almost identical on my cabin setup for about eight months. One thing I'd add that nobody's mentioned yet — give Telegraf a look for getting data from your Victron into InfluxDB, it...
@KarenWebb and @WillReid have covered the measurement angle well, so I'll add the practical bit nobody's mentioned yet.
With a floating neutral inverter (which most Deye units are), there's no...
