Mine generates power during the day but my wife generates grief when the battery monitor shows red—can't work out which one's more efficient. Honestly though @BorderCamper, that inverter one's...

Been thinking about this setup—@CotswoldNomad, what's your actual load profile like in the workshop?

PWM's fine if you're skint or running a tiny system, but MPPT's where the magic happens when you've got decent panel voltage to play with — which you usually do unless you're running a single 100W...

A proper DC fridge is the obvious move here — @CornishNomad's spot on — but if you're set on a conventional unit, you're looking at a 3000W inverter minimum to handle the compressor inrush,...

Thinking about doing the same swap in my garden office setup—currently sitting on ageing AGM that needs replacing every few years. @MuddySkipper, did you end up going for the pair?

Battery anxiety is just what we call "checking the Victron display every 47 seconds" up here, mate — it's basically meditation at this point. Seriously though, the Highlands are ace for...

Brilliant to have you joining! The Highlands are proper gorgeous for off-grid living, though I'd be lying if I said the weather doesn't keep you on your toes battery-wise. What's your current...

The Highlands are absolutely brilliant for off-grid, but yeah—you're going to get intimately familiar with your battery state of charge during winter.

Mate, the cable routing thing is genuinely crucial — I had mine bundled next to the battery cables like some sort of amateur and spent a week convinced my panels were dying in the shade.

Alright, welcome aboard! Always nice to see another Highlands enthusiast — though I'm guessing you've already discovered that "off-grid" and "Scottish weather" are basically...

Fair question @Rob1963. Yeah, it does stop things going catastrophically wrong, but that's just the headline. What's actually clever about a BMS is the balancing bit.

The weight difference is genuinely transformative—I went through this moving my static caravan setup between sites.
Dale Spirit in Batteries & BMS 1 year ago thumb_up 1
Yeah, the planning authority roulette is proper maddening. I'm in an array setup with a shepherds hut and they kept asking if it was "temporary" — turns out the magic word is...

Yep, voltage drop is a killer. I used a Victron calculator tool ages back on the boat and it was eye-opening—turned out I needed nearly double what I'd planned for my solar array run to the charge...

Spot on with the "stops it exploding" bit, but there's more to it. Think of it like this — your BMS is constantly monitoring voltage, temperature, and current across each cell.

Split arrays are definitely the practical choice for those latitude challenges. I've been running dual 2kW strings on my motorhome setup and it's made a real difference — the east-facing panel...

Been there with the weight issue—moving a lead-acid bank around is backbreaking work, literally. Switched to a 48V LiFePO4 setup on my boat last year and haven't looked back. The charging thing...

Winter's when those 10kWh start feeling more like 5kWh, mate—the cold doesn't do lithium any favours.
RetiredNurse49 in Emergency & Backup Power 1 year ago thumb_up 1
The thing that caught me out was oversizing without accounting for charge time. I've got about 10kWh of LiFePO4 paired with 4.8kW of solar, and even on decent winter days I wasn't topping up fast...
Nick Hughes in Batteries & BMS 1 year ago thumb_up 1
Bit confused by the question tbh — you've already got the perfect setup for this. That 3kW Victron on 48V is genuinely overkill for workshop tools in the best way possible. The real constraint...
