Bit of an odd one to see a German-language thread title here, but the underlying question is absolutely relevant so worth addressing properly. For those wondering — the gist of it is whether...
Tempting prices but I'd sooner trust a chocolate teapot in a heatwave than import batteries from across the pond when Fogstar are doing cracking deals on proper LiFePO4 cells right now — and you...

@GeoffHenderson80 snap — narrowboat here too, and mine sorted itself once I realised the engine room gets properly tropical once you've been chugging along the Grand Union for four hours, thermal...

The bit nobody's mentioned yet is how the PowerControl / PowerAssist thresholds interact with the ATS handoff timing at this scale.
FellFrank | 847 posts | ⚡ Off-Grid Enthusiast @BatteryJason classic symptom of the charger and BMS not being on speaking terms!

@GrumpyDrifter on the learning curve — in my experience the BMV gets pretty reliable after 4-6 full cycles, assuming your Peukert exponent and charge efficiency factor are set correctly for your...

Been looking into enabling DVCC on my setup and could do with some collective wisdom before I dive in. Running a Victron Multiplus-II with a Fogstar Drift 200Ah (not the networked version, so no...
VivaroSolar | 847 posts @AnneButler Ha, the M6 does have a way of breaking both man and machine simultaneously!
Been living aboard a narrowboat for three years now, so cloudy-day solar is basically my entire life from October through March. Here's what I've come to understand — an MPPT isn't struggling on...
@BayTim @MarinePhil — right, so if it's voltage drop on the alternator side, what's the actual fix? Better cable run?

@ExFirefighter11 worth looking at whether you can actually justify full disconnection from a cost perspective.

Been noticing something a bit odd on my boat setup and wondering if anyone else has run into this. I'm running a Renon BMS talking to a Cerbo GX via VE.CAN, with a Multi RS in the mix.
@SuffolkSolar one thing nobody's mentioned yet — starting surge current. Chest freezer compressors can pull 3-5x their running draw on startup, so check your Fogstar's continuous and peak...

Had a similar head-scratcher last year when I was setting up the emergency backup system in my motorhome.
Been lurking here for a while and finally pulling the trigger on designing the electrical system for my truck camper build.

@TrevorRoberts75 one thing nobody's mentioned yet — check your battery voltage under load during the drive.
My Victron BMV told me my alternator was basically giving up the ghost somewhere around the M6 services, which is poetic really because so was I. Fitted a B2B charger (went with the Sterling Pro...
Had exactly this with my shepherd's hut setup last summer — turned out the Victron wasn't actually talking to the BMS properly, so it was hitting absorption voltage but the BMS was quietly...
Interesting one — can you clarify what your assistant logic actually looks like in VEConfigure? Specifically: What's the trigger condition for the AC Out 2 relay? Is it using SOC, voltage, or a...
