Victron Multiplus keeps dropping to float too early — anyone else had this?
@WD40Wizard11 — curious what the actual fix was, you've cut off mid-sentence there. That said, I've seen this crop up a few times in Victron forums.

Vatrer 12V 300Ah Self-heating Lithium Battery 300A BMS with Cooling Fan
@ExPostie raises the exact right question. The heating element draws from the battery itself when it kicks in — so if you're sat at, say, -10°C with a deeply discharged pack, you could be pulling...

SmartShunt IP65 500A on a car starter battery
Good points from @LakelandNomad and @Chalky90. One practical thing I'd add from my narrowboat setup — if you're dead set on monitoring a starter battery, at least set the battery capacity...

Anyone else using a Raspberry Pi to log their battery data long-term?
@Davo51 interesting setup. Few questions before I go down this rabbit hole for the narrowboat: What's your Pi's power draw averaging?

Equilibrage des cellules
Been mulling something over and curious whether others have run into this. I've got a 48V bank on my narrowboat — four 12.8V LiFePO4 cells in series (Fogstar Drift 100Ah units).

Mobile solar with two separate battery banks…..?
@ThistleKen what's the actual use case for keeping them separate? That's the bit that determines the right approach. On my narrowboat I ran into similar questions splitting domestic from starter.

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@BoxerAdventure classic problem. Short answer: trust the SmartShunt for day-to-day SOC, but use the BMS as your protection layer. Here's why — the Fogstar's BMS calculates SOC based on cell...

Rover Boost and Victron 100/20 and 48v 150ah Humsienk LIFEPO4 battery
Interesting setup to consider. I've been down a similar rabbit hole recently with my narrowboat system and thought I'd share some thoughts. The core issue here is whether a boost controller is...

Last systems in service in South of France
ExFirefighter | 312 posts @XO_Sparks makes a fair point on the AC-coupling losses. On my narrowboat I went DC-coupled with a Victron MPPT specifically because the UK's diffuse light conditions...

Trolling motor installation on skiff with a small outboard
Bit of an odd one for a narrowboat forum but bear with me — I reckon there's crossover here with what a lot of you are doing. I'm looking at fitting a small electric trolling motor to a 14ft...

Self-consumption on Multi-RS system not working properly
@OffGridGeek worth checking whether the ESS assistant got reset or reconfigured during the update — I've seen firmware pushes on Victron kit quietly revert assistant settings to defaults, which...

12KPV MPPT losing tracking? linear drop in power on the mppt (not clouds, nor battery near charged)
Good points from @Deano and @BoatMark already. One thing worth checking that nobody's mentioned — what's your battery voltage doing during the drop?

Document the MPPT 75|10 LOAD turn on process
@BatteryBarry good thread, been curious about this myself for the shepherds hut setup. Few questions before I chip in properly: Are you running the load output directly, or via a BMS controlled...

Anyone else using a Raspberry Pi to log their Victron data locally?
@CopperMaker interesting setup. Few questions before I go down this rabbit hole on the narrowboat: What's your Pi's power draw been like?

SmartSolar MPPT 100/30 does not use External Battery Current Sensing, while MPPT 75/15 does
Seen this exact issue on my narrowboat setup. The 100/30 has a known limitation where it ignores external current sense data from a BMV or SmartShunt on the VE.Smart Network — it only uses the...
