Hey @GoldenBodger — worth checking your input voltage as well. If the shore power is sitting at the lower end (say 220-222V rather than a solid 230V), the MultiPlus can work harder in passthrough...

@BrookRunner raises something really important actually. When I upgraded the narrowboat I nearly fried my alternator because it was happily dumping full current into the lithium bank without any...

Had the 18A in my garden office setup for about 18 months — honestly it's been fine for a single 100Ah LiFePO4.

HalfAJob55 | Posts: 156 | Location: Array. 48V means half the current for the same watts — thinner cable, less heat, fewer "why is this melting" moments at 11pm on a canal in Wolverhampton.

@RoundTuit I went through almost exactly this rabbit hole when I was expanding my cabin setup last spring.

After the third power cut this winter (rural Lincolnshire, we seem to get hammered every time there's a bit of wind), I've finally decided to stop messing about and put together a proper backup...

@GrumpyHermit replied: @EllaDixon71 Quick correction first — the Wanderer is actually a PWM controller, not MPPT. Renogy's genuine MPPT units are the Rover series.

Spud74 | 156 posts | Location: Array | Interests: emergency backup One thing I'd flag from a backup standpoint — 48v gives you much more flexibility if you ever want to parallel batteries later...

Been running a 200Ah Fogstar Drift LiFePO4 in my shepherd's hut for about eight months now and it's been brilliant until the last few cold snaps.

Been running my narrowboat on a 400W Renogy panel setup with a Victron SmartSolar MPPT since last spring and honestly it's been brilliant through summer.

Been noticing something odd with my setup over the last few weeks now the temperatures have properly dropped.

@SophieHobbs74 Shepherd's hut on wheels is just a motorhome that's embarrassed about it — start by listing every appliance, multiplying watts × hours = Wh per day, double it for cloudy days, then...

Really interesting thread this — I'm in almost the same boat, managing a static setup at my plot plus keeping the van topped up when I'm away. One thing I'd add that nobody's mentioned yet: I...

Really interested in this thread — been considering the exact same setup for my cabin. @VanJim raises something I hadn't thought about.

Picked up a 280Ah LiFePO4 cell bundle from Fogstar back in 2021 and built a 24V 280Ah bank — fully expecting the usual "budget cells = early death" outcome, but here we are in 2025 and...

XJ_Solar | Posts: 312 | Location: Array Worth noting that a DC-DC charger (B2B) will properly profile-charge your LiFePO4 — the split-charge relay just dumps alternator voltage straight in, which...

@GarySmith58 good shout on coefficients. One thing I'd add from running mismatched panels on my boat — shade tolerance matters more than people realise with mixed strings.

Currently putting together the solar setup for my tiny house build and I've got a bit of an odd situation.
