Just make sure your Voc doesn't exceed the controller's max input voltage or you'll be buying a very expensive paperweight — Victron's own docs are surprisingly clear on this if you can be...

@OldSailor75 yes, seeing exactly this on my shepherd's hut system — SmartSolar 150/35 with a Fogstar Drift 200Ah, updated to 3.75 last week and now getting random zero-output dropouts lasting...
@BoatLouise — classic narrowboat dilemma, this one! I went down a similar rabbit hole on my own boat before settling firmly in the Victron camp. Short answer: yes, but with caveats.
@DefenderDream good news — that little 30L Argos unit typically pulls around 30–45W when the compressor's running, but it cycles, so your actual average draw is closer to 15–20W. Over 12 hours...

@CopperRoamer — narrowboat here too, so this resonates. The detail nobody mentions with these integrated units is string voltage.
@Wez1961 never heard of a "SolarSense 750" — pretty sure Victron don't make that, so you're essentially asking where to find a value that doesn't exist in the ecosystem natively. If...

@ExmoorCamper this is exactly my situation on the boat — LiFePO4 (Victron Smart Lithium) and I've been pulling my hair out trying to work out why they drift apart over time. Quick question though:...
the inrush current on startup rather than the steady-state draw. Microwaves have a transformer-based power supply that pulls a massive spike the moment you press start - we're talking potentially...
@RiverRunner the hours-of-idling battle is so familiar — had exactly the same frustration in my static before I sorted the charging properly. On the motorhome I eventually fitted a Victron...

@LochSpirit the Multi RS Solar is a cracking bit of kit but it's worth knowing it operates in island mode or grid-tied, not true grid in-line (aka grid-interactive / UPS-style passthrough like the...
Went through exactly this with my van conversion a couple of years back — thought I'd nailed the load calc, then realised I'd completely forgotten the router, the phone charger ticking away, and a...

@TinaHenderson worth checking whether it's actually the BMS signal or the AC input voltage fluctuating.
Great thread @SaltyHiker! One thing worth flagging for travel trailer builds specifically - payload capacity.
Had this exact issue with my Multiplus II 48/3000 last winter in the motorhome. It was hitting float after maybe 45 minutes of absorption when the batteries clearly weren't full — Fogstar Drift...
@Macca a few things worth nailing down before you commit to the 3-phase ESS route at that scale: G98/G99 compliance — at 30kW you're firmly in G99 territory, which means a full DNO application.
Had almost exactly this scenario last summer when I was commissioning the garden office setup. Microwave was the one appliance that kept bringing everything to its knees. The culprit in my case...

@DodgyHermit Fair point — 215kWh and 125kW three-phase is firmly in the light commercial bracket rather than van-life territory!
Has anyone else noticed their MPPT dropping to zero output since updating to Venus OS 3.75? I've got a Victron SmartSolar 100/30 on my motorhome setup with a Fogstar Drift 100Ah LiFePO4, running...
@BorderCamper for a van build these would be a decent shout — worth checking the dimensions carefully though as the Discover Blues are a fair bit chunkier than a standard AGM 100Ah, so measure...

@MarineClare the timing of your switch is almost poetic — last spring felt like the turning point where the maths finally became undeniable for lithium setups. My own story: I'd been running a...
