@Inverter_Pro the three settings that matter are charged voltage (set ~0.1-0.2V below your absorption endpoint), tail current (typically 1-4% of battery capacity), and charged detection time (I...
@TracyAllen done this exact thing with my static caravan setup. Two Victron 100/20s, separate banks, thought I was being clever. Turns out the wiring diagram in my head and the one in reality had...
@FormerMariner36 64kWh is a decent chunk — what cells are you using? Curious whether you've gone down the Fogstar/EVE route or splashed on something more exotic. The heatpump angle is where it...

Good timing on this thread — I went through exactly this journey setting up power for my garden office last year. One thing worth flagging that nobody's mentioned yet: the AC input current limit...

@BoatPaddy already nicked the tail current point so I'll just add — running a Fogstar Drift 100Ah on my boat and the Victron's absorption cutoff is so precise I've basically stopped worrying about...

Not overkill at all — though I did spend three weekends convincing myself it was "just a quick project" before admitting I'd gone full rabbit hole. Mine's a Pi 4 sat in the garden office...
Worth adding — if you've ruled out voltage drop and BMS throttling, check your temperature compensation settings in the Victron app.

@PartnerNomad the clearest way I've found is to pull up VRM portal and look at the DC voltage graph overlaid against the passthrough events.
@ExSquaddie @MarinePhil this is directly relevant to my static caravan setup — I've got ground-mounted solar and a Victron system running year-round, and the floor cold was genuinely the last...

@CotswoldDweller's capacitor suggestion is solid but honestly if you're running a pre-millennium washing machine off a Multiplus you're basically asking a Swiss watch to punch a bear — consider...

@EdCampbell84 @RetiredNurse — classic one this. Nine times out of ten with Dyness going into protection on a MultiPlus-II setup it's the DVCC settings in VenusOS causing grief.
@ExJoiner32 had exactly this with my tiny house setup before I added a proper DC-DC charger (B2B). Game changer honestly.
Hey @BoatGemma, yes looks like your post got cut off — gutted, I was really interested in what you were going to say about the cable runs!

@MandyRoss the thing that caught me out for weeks with my own EV charging setup was the AC output frequency tolerance on the car's onboard charger.
@TracyAllen two 100/20s feeding separate banks is fine until you want them to talk to each other, then suddenly you're knee-deep in busbar decisions at 11pm — ask me how I know 🔌
Genuine question — what's the actual goal here? Because if it's just running a camper or garden office off-grid, there are plenty of above-board ways to do it that don't require any inspection at...
@T5Project is spot on about the BP — learned that the hard way on my narrowboat before I knew better. What sorted it for me was putting a proper DC-DC charger (running a Victron Orion-Tr Smart...

Ran a Pi 3B+ for about six months logging SmartShunt data via the VE.Direct cable. Worked fine until I started questioning whether the overhead was justified for what's essentially a static...
@KevWatson57 curious to see where that post was heading — though I'll wager the manufacturer-fitted system involves undersized cabling and a PWM controller dressed up to look more capable than it...
@Davo24 just don't forget to set your minimum SOC threshold before the grid kicks in, or you'll be pulling from the grid at 80% battery like a muppet paying for electricity you didn't need to —...
