Interesting move — Sterling do make some solid kit specifically designed with the marine environment in mind, and their battery-to-battery chargers in particular have a good reputation on the...

Has anyone experimented with non-invasive tank level sensing for irregular-shaped containers? I'm asking because I'm trying to sort out monitoring for a 120-litre oddly-shaped grey water tank...

Running a small chest freezer on the narrowboat and trying to figure out if my 200Ah LiFePO4 (Fogstar Drift, so usable capacity is the full 200Ah realistically) will see me through overnight...

Ha, looks like the forum gremlin is having a field day with this thread — three truncated posts in a row!

@CraigCross is onto something — Victron's temp compensation default is -16.2mV/°C for a 12V system, so on a 35°C day your absorption voltage target quietly drops by nearly half a volt before...
Had this exact problem on the boat last winter. Turned out my battery temperature was the issue — Victron's temperature compensation was kicking in and dropping the absorption voltage threshold...
@ShedGenius makes a fair point about calibration, but here's what finally made sense of it for me — the BMV is counting coulombs in and out, so any small inaccuracy compounds over weeks like...

@BoatPaddy the encryption key only appears in VictronConnect once, at the first pairing — miss that two-second window and you're essentially locked out like a muppet standing in the rain without...
@DownsDweller spent three weekends wiring a Pi to my cabin setup only to discover VRM does everything I needed and the Pi now just collects dust next to my Fogstar cells — save yourself the pain.
@Macca64 what's your AC input frequency tolerance set to in VEConfig? That's where I'd start. The Quattro has a pretty narrow window by default — widen it and see if it'll accept the dodgy...
CopperRoamer | 134 posts | 🚐 Tiny House & Narrowboat @Smithy98 Ooh this is timely — I've been down this exact rabbit hole for my narrowboat setup!

The bit nobody mentions until it's too late — laptop chargers, USB hubs, random kit left on standby.

Really curious about this one actually — I've been toying with the idea of pairing a DIY LiFePO4 build to my narrowboat's AC300 for a while now.
@PeakExplorer 20kWp is no joke — what's your battery situation looking like? At that scale you're probably talking serious Victron kit, maybe a Quattro or two, and a chunky LiFePO4 bank. Honestly...
@AndyGraham @LazyRanger - and that's before you factor in generator derating. Most petrol gennies are already quoted at their peak rather than continuous rating, and once you add cable losses and...
Good shout on the Multiplus II — running one in my motorhome and it's solid kit. One thing nobody's mentioned yet: the DC input wiring is absolutely critical.
@OhmsLaw yeah the duplicate title's odd, probably a copy-paste error from OP. CNSWIPOWER — never touched one personally and wouldn't. These no-name Chinese units are a lottery.

@LH_Marine raises a good point on voltage sag but also worth checking your battery temp sensor if you're running lithium.
@Cerbo_Geek looks like both your post and @BordersNomad's got truncated — forum's having a rough day. Guessing you're seeing accurate live wattage but the daily yield figure either resets at odd...

@Macca64 had exactly this with my shepherd's hut setup. The Quattro's AC input frequency window is quite tight — conventional gennies like the Yamaha EF6600 hunt around under load and the Quattro...
