@LochChild great thread. One thing I'd add to what @MickDavies is touching on — don't overlook your battery monitoring once you've made the swap.

Been thinking about this a fair bit lately, particularly relevant to those of us who aren't grid-tied at all. For the narrowboat and the shepherd's hut, I've no export option whatsoever — so the...

Had this exact issue on my narrowboat last winter. Turned out to be the VE.Direct Bluetooth dongle rather than the MPPT itself — the dongle was dropping its BLE connection when temps dropped...
Been mulling over a setup question and curious whether anyone's tackled something similar. Running a 48V system with a pair of Victron Multiplus II 3kVA units (planning to add a third eventually),...
Been wrestling with this one myself over the past few weeks, so thought I'd start a proper thread rather than necropost on older discussions. My setup is a Victron Multiplus-II with a Cerbo GX,...
Had something similar happen with my Victron Multiplus-II 48/3000 when I first installed it last year — genuinely concerning when you've just dropped that kind of money and get absolutely...

@EcoFlow_Queen the 48V input range is the first thing I'd be checking in the actual datasheet rather than the marketing copy — these units often quote a wide PV input voltage but the MPPT tracker...
Jumping in while we wait for @DucatoDream to finish the thought too — Quick question for the thread generally: is this primarily a battery state-of-charge issue triggering the alarms, or is it...
ExJoiner in Inverters & Chargers 3 months ago
This is something I've been tinkering with on the boat actually, so it's close to my heart. The Cerbo GX absolutely can do this via the Generator Start/Stop logic, but what you're really after is...

@TorDweller should be fine honestly. Chest freezers are decent because they cycle on/off rather than running flat-out — realistically that 45W unit is probably averaging 15-25W over time once it's...
Quiet Trekker in Q&A 3 months ago
So I'm in the middle of converting a long-wheelbase Transit (she's a beauty, chaos incarnate, and currently missing a ceiling) and I'm trying to plan the electrical system before I do something...
Kangoo Dream in Q&A 3 months ago
Running a small chest freezer off a 200Ah lithium (assume 12V, so 2.4kWh usable at ~100% DoD, though I'd stick to 80% in practice giving ~1.92kWh) overnight — is this feasible? Context for my...

Just got my bill and I think my smart meter is having a laugh at my expense — up another £40 on last month and I've barely been home!

Boycie | 1,204 posts @PVKing @FormerMariner24 worth adding — if you're running VE.Direct into a Cerbo GX or even a Raspberry Pi with Venus OS (which I do on the narrowboat), the system clock...
@VivaroAdventure mine lasted exactly long enough for the warranty to expire, which I'm convinced is a firmware feature on these things.

@T5Project lol yeah UK solar noon is doing a lot of heavy lifting as a concept rn 😅 One thing nobody's mentioned — check the junction box on the back.

Been thinking about this one a lot lately since a mate of mine is planning something similar. He's got a Multiplus II 5kVA running his off-grid setup and wants to chuck a Victron EV Charging...
Ran a cheap PWM on my shepherd's hut for about eight months. Honestly? It worked, but I had zero visibility into what it was actually doing to my batteries.
Marsh Lover in On a Budget 3 months ago
Been thinking about this a lot lately after a chat with a fellow motorhome owner who runs a proper home backup setup too. So the scenario I keep coming back to — has anyone here run a Victron...
@Brummie84 genuine question — are you running DVCC with an external BMS or letting the Multiplus handle charge control itself?
