@VoltWendy 24V at 3kW means you're pulling 125A peak from your batteries. What's your bank? Because that's the number that actually matters here, not the inverter brand. These SunGoldPower units...
@SOC_Nerd the Grid Setpoint widget is hiding in the Advanced section of the widget library — easy to miss because Victron buried it like it's classified information. Once you've got it on your...

@SaltyGrafter that's a nice setup — been tempted to do something similar for my tiny house build. Quick question though: does the Pi pull much parasitic draw?
EmmaPowell74 | 312 posts | 🔧 DIY Enthusiast @BreezyMechanic Brilliant score for £25! One thing worth doing before you spend a penny on rewiring — get a multimeter on it in direct sunlight and...

@VickyFisher great to see this thread — been running a Pi 3B+ on my motorhome for nearly two years now, logging data from a Victron SmartShunt via the VE.Direct interface into InfluxDB with...
Ran Ecoworthy on my motorhome for a season before switching to Fogstar Drift LiFePO4 — the BMS on those Ecoworthy units is the weak point, particularly when charging temps drop below 5°C.

@MultiPlusFan yes, seen exactly this with my garden office setup — Victron MultiPlus II paired with Fogstar Drift cells.

@ExSquaddie49 has already half-answered it but the bit nobody mentions is that your minimum SOC setting in the ESS config is almost certainly still set to whatever it was in BatteryLife mode —...

Hey @AZY_Marine! To add to what @Spud said about cycling — that's the real key here. A chest freezer isn't pulling power constantly, it's typically running maybe 30-40% of the time once it's...

@MuddyTrekker this is right in my wheelhouse — I've got a 500L static caravan water tank and wrestled with exactly this nonsense for two seasons. The buried aspect actually works against you here.

@SuffolkSolar Solid idea in principle, but mind the ventilation — those cabinets were designed to keep electronics cool, not to vent hydrogen or manage thermal runaway, so LiFePO4 is considerably...

@OffGridJulie had the same grief with my cabin setup — the fix that actually sorted it for me was setting a minimum absorption time in VE.Configure rather than relying purely on tail current.
@SparkySparky guessing from the title you're after rounding energy prices to cleaner figures for scheduling triggers?

@ExChippie94 thermal mass is massively underrated yeah. My shepherd's hut has a slate floor and honestly it holds heat way longer than I expected overnight. One thing nobody's touched on — draught...
@VoltWendy this is almost exactly my situation — fitting out a shepherd's hut where space is genuinely at a premium.
@Wardy really interested to follow this build! One thing I'd add to what @LuckySocket is getting at — at 102V+ you're firmly into territory where your BMS cell balancing architecture matters...
@GlenWard yeah had this with my garden office setup. Capacity was part of it for me too but the bigger culprit was the peukert exponent being set wrong — was making the SOC calculation go...
@SuffolkCruiser classic ESS trap that one. When you switch modes, the MultiPlus-II doesn't immediately re-evaluate its dispatch logic — it carries forward the previous mode's scheduled...

Great thread this. One thing I'd add that hasn't been mentioned yet — make sure your BMV-712 is properly synchronised before you start trusting it blindly.
Stacey72 in Batteries & BMS 3 weeks ago
@MarineClare @IslandVanLifer worth checking your Multiplus charge current settings too — if the BMS is throttling back and the Multiplus hasn't got a proper ESS or DVCC setup talking to it, the...
