Been keeping an eye on these VEVOR hybrid units for a while now. The toroidal transformer spec is genuinely interesting at this price point — toroids are typically quieter and more efficient than...
Running a Quattro alongside a Skylla-TG charger on the same lithium bank is something I've been mulling over for my motorhome conversion, so this topic is very timely. My current setup uses a...

Been through exactly this with my place. The honest answer is that no amount of clever log management fixes a poorly insulated shell — that's where I'd start before anything else.

Had this exact issue last summer with my 100/20 on the garden office setup. Drove me absolutely mental for weeks. Turned out my battery voltage sensing was off — the MPPT was reading at the...
@ForestBoater mate, your Multiplus II is probably ignoring your ESS schedule because the minimum SOC floor is set too low — it'll happily nick grid power the moment it decides the batteries need...
Worth noting there's a balance to strike with that threshold though — if you set it too low you risk drawing the starter battery down without realising, especially at extended idle.

Been thinking about this a lot lately because I'm doing something vaguely similar with the shepherd's hut — trying to figure out which battery chemistry plays nicely with a single charging source...

Been scratching my head over this one and hoping someone can point me in the right direction. I'm planning to expand my solar setup on the narrowboat and I've got a couple of panels that don't...

@RustyTinker been thinking about doing something similar for the static caravan. Few questions though — What kind of output were you actually getting in real-world conditions, not just peak?

Made a similar jump recently with my shepherd's hut setup — moved away from a pair of Pylontech US2000s running at 48V nominal and switched to a 48V (51.2V actual) LiFePO4 bank from...
Ran into this on the shepherd's hut tow vehicle — turned out the alternator itself was the culprit, not the Orion at all; a tired alternator sags badly under load and the Orion's low-voltage...

Been scratching my head over something similar with my narrowboat setup and wondered if anyone else has wrestled with this. Running a Multiplus-II GX with a 48V Fogstar Drift lithium bank and a...
Had a frustrating evening last week that I reckon some of you will recognise. Been running a single Multiplus-II 48V/5000 here for a couple of years — originally on AGM, no dramas whatsoever.

Solid choice going down the LiFePO4 route — worth every penny once you're past the initial setup headaches. One thing I'd flag immediately: venting requirements for LiFePO4 are actually far less...
Not bad at all — this is literally what MPPT controllers are designed to handle. The controller doesn't just "shut off", it throttles back the power draw from the panels through PWM...
@FrostySocket genuinely curious what the two culprits turned out to be in your case? I had a Cerbo rebooting sporadically last autumn and eventually pinned it down to a loose 12V supply connection...

@BevJackson64 correct on both counts, but there's a third setting people consistently overlook: charged voltage threshold.

My shepherd's hut setup screams the same frustration — already had two Victron SmartSolars wired in perfectly before I even looked at the Multi RS specs, felt like being sold a printer with ink...
Did exactly this on my 32ft sloop two seasons ago and honestly it transformed the charging situation. The stock alternator was doing a half-hearted job — wandering around 13.8V and calling it done...

Got me thinking about a situation I ran into last spring when I was experimenting with different charging sources on my AGM bank. Had a DC-DC charger — a Victron Orion in my case — that was...
