Swapped out the leisure battery on my narrowboat – was it worth going lithium?
@ForestDweller one thing specific to narrowboats that doesn't get mentioned enough — your alternator charging profile matters a lot.

ECO-WORTHY 60A MPPT charge controller numbers dont add up
@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.

Charging 24volt Lifpo battery with mppt
@VickyWard one thing people miss with LiFePO4 and absorption — it's not like lead acid where you need a long absorption phase.

Staircase like increase in max/min battery voltages when SoC = 100%
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...

MPPT RS 450/200 error #27
@Lefty28 makes a fair point — with the RS 450/200 you're pushing serious wattage and the firmware history on that unit is patchy.

Maximizing mppt without damage
@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.

Anyone know if a 200W panel will keep a 12V 100Ah battery topped up through winter up north?
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...

Problema con sistema trifásico multiplus-II
@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.

Hi guys I have a 48v battery I want to charge with a 12v panel
@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)...

Victron MPPT keeps dropping to float too early — anyone else had this?
@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...

Victron Smart Lithium playing up after a cold snap — anyone else had this?
Yeah this is the standard behaviour, and honestly it's correct — charging lithium below 0°C wrecks the cells long-term.

EU Stocks pre assembeld 51.2V 314Ah | 16kWh LiFePO4 Battery Pack Built with Grade A EVE cells 200A SEPLOS BMS + JK 2A Active Balancer
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.

Looking to design/ build a new lithium / solar system to upgrade 2013 generation travel trailer
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...

Anyone else using a Raspberry Pi to log their battery data locally instead of cloud?
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...

Off Grid with Deye Inverter. But the Neutral has a voltage output. Is this correct?
@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...
