RustyCaptain | Posts: 847 Worth flagging that whilst @ExPostie86 is right about the MPPT chasing the voltage curve, your limiting factor in series will be the current — the 200W panel almost...

@PanelBuff on a Beta 43 with a decent alternator, the 30A is worth every penny. The 12A will just tickle that 200Ah Fogstar — you'll run the engine for an hour and barely move the needle. Key...

Good question @VoltDai — yes, I had mine signed off by a Part P registered electrician last spring. He was perfectly happy with it once I explained the setup clearly and showed him the Victron...

Trying to sort out power for my static caravan without spending daft money. Got a small Renogy 100W panel sat in the garage from a previous project — thinking that's the starting point.

WattBaz | Posts: 1,203 | Location: Peak District @WattVicky What @CornishCamper is getting at is spot on — but the flip side worth mentioning is that whilst your voltage climbs in the cold, your...

Reply by Midge93: @DodgyRoamer sounds like a cracking project! Before anyone can give you sensible sizing advice, it'd help to know your rough daily load in watt-hours — add up everything you'll...

@Spider6 that's pretty much par for the course in January — even down south I'm pulling similar numbers on good days.

Been trying to get hold of some 280Ah EVE cells from Fogstar for about six weeks now. Every time they come back in stock they're gone within a day or two.

@Chippy that garden office build of mine taught me the same thing — constraints force you to think properly rather than just throwing space at the problem. What OBC are you running?

Been planning the DC side of my motorhome build and keep going back and forth on this. Currently running a 200Ah Fogstar Drift LiFePO4 as my leisure bank, charged via 400W of roof solar through a...

@Chalky right so I had almost this exact crisis with my static caravan setup last January — panels doing virtually nothing for days on end, grey skies just sitting there being useless. The thing...

Seconding everything said above, and just to add one practical tip — before you raise the ticket with Victron, take screenshots of whatever you can currently see on the VRM portal, even if access...

@KangooAdventure that's a rough one — Middlewich stretch isn't exactly littered with chandlers either. My minimum viable layer for the garden office setup taught me this: one independent 12V 100Ah...

Really curious what @KeithYoung was about to say about bus bars — that reply got cut off but it sounds important! @WillStevens one thing I'd genuinely obsess over before touching anything else:...

JohnShaw86 | 847 posts @MuddyRanger yeah it's been quite dramatic hasn't it. I picked up a 100Ah EVE cell kit from AliExpress back in spring for about £85 all in - would've been closer to £140-150...

After that 14-hour outage in January I knocked together a grab-and-go setup from the boat — 100Ah Fogstar lithium, a Victron 375VA inverter, and a 30W Renogy panel bungee-corded to the fence.

Finally got round to logging proper temperature data on my narrowboat bank — four 100Ah Fogstar Drift LiFePO4 cells wired in series for a 12V/400Ah setup, managed by a Victron SmartShunt and a...

Good shout from @ValleySolar and @Del72 on those points. One thing I haven't seen mentioned yet — have you looked at your ESS minimum SOC setting in VRM?

Finally pulling the trigger on a proper garden office build this spring — 4x3m timber frame going in the back garden.
