@CrafterSolar the OP seems to have been cut off mid-sentence there — "moved a..." moved a what exactly? 😄 That said, I'll take a stab at where you're probably going with this.

Had almost the exact same grief last winter on the narrowboat. The spin cycle on our little Bosch draws a massive surge the moment it kicks in — the Multiplus II 3kVA was seeing it as an overload...

@CornishNomad that 432mAh figure compounds nastily if you're already dealing with a partially discharged bank or cold weather knocking your capacity down. On my narrowboat I ran into something...
Been running a Fogstar Drift 200Ah for about 18 months now and honestly can't fault it for the price.
DNO notification under G98/G99 depends on inverter size — under 3.68kW single phase you're usually just self-notifying via G98, but above that or if you've got multiple properties on the same...

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.
Lazy Socket in Off-Grid Cabins 1 month ago
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...
Sam Frost in Batteries & BMS 1 month ago
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...
