Anyone else gone down the rabbit hole of MCIs with Tesla's solar inverter? Trying to get my head around whether the existing rapid shutdown compliance on my SEG 420W panels carries over or if I'm...
Been doing exactly this for the past two summers on the moors and it's a proper rabbit hole worth diving into. The key bit most people miss is that a 36V e-bike pack is typically charged to around...
Been through this twice now — once on the motorhome, once on the narrowboat. The honest answer is: if you're replacing like-for-like, you're just delaying the real decision. Worth checking what...
Honestly I'd be cautious about going full AliExpress for an inverter — had a mate who bought an unbranded 3kW unit for his narrowboat and it fried within 8 months.
Running a modest setup on my narrowboat at the moment — Victron Multiplus-II 3000 GX paired with a couple of Fogstar Drift 100Ah LiFePO4 batteries (JK BMS connected via CAN), plus a 150/35 MPPT...

Bought three of them last summer for the shepherd's hut project. Two are still going fine, one developed a hotspot within about four months — you could actually see it delaminating in the corner.

Mine showed a 12% difference for weeks until I realised my Peukert exponent was set for lead-acid on a lithium bank — classic. The short answer is: trust neither blindly, use both as a...

@Spud79 makes a fair point about battery sizing — we went through exactly this debate when planning our narrowboat setup.

TerryLewis | Posts: 847 @DODQueen interesting idea but I'd steer well clear of daisy-chaining Multiplus units like that.
Been thinking about this one a lot lately after fiddling with my shepherd's hut setup over winter. I've got a slightly similar layered system — 12v lead acid handling some legacy kit that doesn't...
Thread title's Spanish but the wiring question's universal — @OldSailor's right, DC systems aren't rocket science once you stop second-guessing yourself. Key bits most people bodge: Fuse every...
Great thread, this. @RetiredEngineer86 makes a solid point about condensation, but worth adding that even if the sensor itself is fine, make sure your battery temperature compensation settings in...

The ZYC packs typically use a JK or DALY BMS internally, and neither talks to Victron natively without a separate CANbus adaptor or a properly configured DVCC setup.

Been noticing something a bit odd with my setup over the past couple of weeks and wondering if anyone else has seen the same. Running a Victron Multiplus II with a Fogstar Drift 24V battery bank...

Beyond the firmware and wiring points already covered, something that bit me hard last winter was the battery temperature compensation settings in the Victron.
Been thinking about this setup lately and wondered if anyone's had hands-on experience with it. I'm looking at running a Victron Multiplus-II in my cabin to handle the main battery bank and solar...

Had this exact issue in my shepherd's hut setup last summer. Multiplus II kept jumping to float after maybe 2-3 hours of bulk even though the Fogstar Drift LiFePO4 wasn't anywhere near...
Been running a Pi 4 with Venus OS Large for about 18 months now and honestly it's transformed how I manage the system.
Classic narrowboat problem this — shore power disappears at a marina and suddenly your whole system throws a tantrum like a toddler whose biscuit fell on the floor. My Victron Multiplus-II does...

There are a few layers to unpick here, and I suspect the question might be coming from a North American context — because in the UK we're working with 230V as our standard mains voltage, which...
