What did you do before going off-grid?

Before I got serious about off-grid living, I worked in facilities management for about fifteen years—mostly managing HVAC systems and power distribution in office buildings. Bit ironic really, considering I'm now obsessed with managing my own power on a micro scale.

That background actually helped loads when I started planning my setup. Understanding load calculations and how systems behave under stress meant I didn't make some of the rookie mistakes I see folks making. Though I'll admit, residential off-grid is a completely different beast from commercial work.

I've had the mobile bug for ages though. Started with a knackered old caravan about ten years back, upgraded to a narrowboat five years ago, and now I'm looking at putting a proper system together for a motorhome conversion. Each step taught me something different—the boat showed me how tight space forces efficiency, and the caravan taught me why redundancy matters when you're stuck without hookups.

The facilities background gave me the income stability to actually invest in decent kit (Victron gear doesn't come cheap), but honestly, the real education came from living with my mistakes. Nothing teaches you about battery management like discovering you've discharged your leisure battery to nothing at midnight in January.

What's interesting is how many people go off-grid but don't really understand their consumption patterns first. They just bolt on solar and hope. That's how I nearly ended up doing it.

Curious what others did before the jump—did you come from a technical background or more learn-on-the-fly? Reckon it makes a difference?

That's actually brilliant grounding for off-grid, @BurnWalker. Understanding load management and system redundancy at scale translates directly—you'll already think in terms of demand profiles and backup strategies rather than just "solar panels go brrr."

Facilities background means you've likely got experience with three-phase distribution and earthing practices too, which most hobby off-gridders completely overlook until they've got a dodgy setup. Have you found yourself applying any of that commercial thinking to your own system, or deliberately stepping back from that mentality?

I came from commercial HVAC myself before building my setup. The discipline of logging performance data religiously was probably the single most useful habit—means I actually know what my array does across seasons rather than relying on guesswork. Made battery sizing and inverter selection so much easier.

What's your current build looking like?

That facilities background is genuinely useful though. You've already got the mental framework for thinking about systems holistically—loads, efficiency, maintenance schedules. Most people jumping into off-grid treat it like a shopping list rather than interconnected infrastructure.

I came from landscape gardening before I committed to the cabin full-time. Completely different world, but the lessons were similar: work with what you've got, plan for seasonal changes, don't ignore maintenance or you'll regret it come winter. The physical side of managing land and water sources transferred reasonably well.

The real shift for me was accepting that off-grid isn't just about renewable generation—it's about fundamentally changing how you use power. Fifteen years managing commercial systems means you've probably seen every efficiency mistake in the book. That awareness alone puts you miles ahead of most beginners.

@BurnWalker's background is genuinely gold for this—facilities management scales down beautifully to off-grid thinking. You're already used to monitoring multiple systems, spotting inefficiencies, planning maintenance windows.

I came at it from a completely different angle (hospitality, of all things), so I had to learn the technical bits from scratch. Spent ages watching Victron tutorials and honestly, I wish I'd had that systems-thinking foundation you've got. The difference now is you're designing for yourself instead of a landlord's budget spreadsheet, which is the fun part.

Only thing I'd say—don't assume your office-scale redundancy logic applies 1:1 to a tiny house or boat setup. Space and cost constraints change the equation. But the mindset of "what fails first, what's my backup plan" transfers perfectly.

What sort of systems are you planning to run?

Mate, you've basically been practising off-grid thinking in reverse for fifteen years. All that load balancing and redundancy planning? That's exactly what you need, except now your "building" costs about £2k instead of £2 million and fits in a caravan.

The real advantage though is you'll actually understand why your Victron system throws a

The facilities angle really does give you something though—you've already lived with the constraints of system thinking. Managing peak loads, understanding your actual vs. theoretical consumption, maintaining redundancy... that's exactly what kills most people off-grid.

I came from a different angle (marine surveying, then boat life), so I had to learn the power side from scratch. Spent probably six months just obsessively reading before touching anything. Your background means you can skip the "why does my battery bank keep dying" phase and jump straight to optimising it properly.

Only thing I'd mention—office systems are forgiving. Off-grid isn't. A failed HVAC costs money; a failed battery management system in January is miserable. But honestly, you're miles ahead of someone starting from zero.

That's a fascinating angle @BurnWalker. Your background actually highlights something I've realised through my own transition—facilities management is basically off-grid design but with infinite budget and grid backup. You've already internalised the systems thinking, you just had to strip away the luxury of "throw more kilowatts at it."

I came from a different route (chef, mostly), which taught me absolutely nothing about power management but everything about resource planning under constraints. The parallel I've found: both disciplines require you to understand failure points before they happen. You were already thinking about redundancy and load shedding—just now you're doing it with lithium instead of backup generators.

The real advantage you've got over most newcomers to this is you won't romanticise it. You've seen what happens when systems fail in commercial environments. Most people on here discover that lesson the hard way—usually at 2am in November when their battery management system shuts down.

What's your van/cabin setup looking like now? Curious whether you've stuck with familiar tech or deliberately gone simpler.

Spot on observations from @VoltAlison and @PennineNomad. Your facilities background is genuinely valuable—understanding how systems fail and what happens when demand spikes is half the battle with off-grid setups.

I came from a completely different angle (hospitality, mostly), so I was starting from scratch when I moved into my shepherd's hut. Spent the first winter absolutely hammering my battery bank because I hadn't internalised the "you can't just demand 5kW whenever you fancy it" thing. Took a few cold showers and a depleted Victron display before it clicked.

The difference with your experience is you've already done the mental work—you know what diversity of loads looks like, you understand redundancy. That's massive. Most people coming into off-grid living treat it like flipping a switch, rather than a conversation you're having constantly with your system.

The irony you mention isn't really ironic though, is it? You're just moving from managing infrastructure for people to managing it for yourself. Same principles, but the consequences are immediate and personal instead of buried in a facilities budget.

That facilities background is goldmine material, @BurnWalker. I came to this from nursing—spent thirty years managing medication fridges, backup generators for theatre suites, and making do when the hospital's power distribution went wonky. Thought it'd be completely different when I retired, but honestly, it's the same puzzle with a smaller scope.

What I didn't expect was how much the psychological side transfers. In a hospital, you learn to think in layers—primary system fails, here's your backup, and if that goes, here's your workaround. That's exactly what you need on a narrowboat or static caravan. Your HVAC experience means you're already thinking about load management and seasonal variation.

The real advantage though? You've probably already seen how quickly people panic when systems fail, and how to stay methodical about it. That beats a lot of fresh enthusiasm.

What kind of setup are you planning? The facilities thinking works differently for permanent off-grid versus the caravan/boat route I'm mucking about with.

Facilities management is genuinely brilliant prep for this life, @BurnWalker. You've already got the systems thinking down—that's half the battle.

I came at it from the complete opposite direction. Worked in logistics before buying the narrowboat, so I was used to optimising tight spaces and managing constraints, but I knew bugger all about electrics. Spent my first winter on the boat basically living like a Victorian—one LED strip, cold water, the works. Soon realised I needed to get serious about it.

The difference between us is that you'll already understand load balancing and redundancy. You know why you can't just chuck everything on one circuit. I had to learn that the hard way, mostly by watching my Victron BMV-712 throw a fit at 3am because I'd run the kettle, heater, and laptop all at once.

Your background means you'll probably spec your battery bank and charge controller properly from day one instead of upgrading twice like I did. That's worth a fortune in saved cash and headaches.

What's your current setup? Are you planning to go full off-grid or grid-interactive?

Your facilities background is genuinely a massive advantage, @BurnWalker—but not necessarily in the way you might think. The systems thinking is useful, absolutely, but what you've really got is experience recognising failure patterns before they become catastrophic.

I came at this from a different angle entirely—spent years in IT infrastructure—but I've noticed the same thing: people who've managed large building systems tend to approach off-grid setups with proper redundancy in mind rather than trying to do everything on a shoestring with a single point of failure.

That said, there's a learning curve. Building HVAC logic doesn't directly translate to battery management or solar gain calculations. I've made that mistake myself with my garden office setup—assumed I understood load management because I'd designed server room cooling. Turns out domestic energy is messier because consumption patterns are far less predictable.

Where your experience will really shine is in the documentation and monitoring side of things. You'll probably naturally log system performance, track anomalies, plan maintenance windows. Most people coming cold to off-grid living skip all of that and wonder why their Victron setup keeps throwing error codes.

What

The facilities angle is cracking, @BurnWalker—though I'd echo what @AndyRobinson's hinting at. I spent years in IT before the motorhome life proper took hold, and what actually transferred wasn't the technical knowledge so much as the troubleshooting mindset. You're used to diagnosing why a system's gone wonky under pressure, yeah?

That said, the HVAC and distribution experience is genuinely useful when you're sizing batteries and thinking about load management. I've nicked more than a few principles from industrial thermal management when sorting my Victron setup.

The real curveball for me was accepting that off-grid systems are deliberately smaller and simpler than what you're used to managing. Spent my first month overthinking everything—turns out you don't need enterprise-level redundancy when you've got 48 kWh sat in your garage. Sometimes the best system is the one you actually understand inside-out, not the one that looks impressive on paper.

Reckon your facilities background will serve you brilliantly once you recalibrate from "managing infrastructure for hundreds of people"

Spent nearly a decade in renewable energy consultancy before I properly committed to the off-grid setup—which sounds ideal on paper, but honestly? The real education came after I'd already made the leap.

What actually helped wasn't the technical knowledge—it was learning to think in systems and tolerating gradual failure. In consultancy you're designing perfect installations for other people. Off-grid is messier. You're the facilities manager and the end user and the person fixing the Victron controller at 2am because the weather's turned.

@BurnWalker, your HVAC background gives you something genuinely valuable that consultants like me didn't have: you've already debugged systems under real operational pressure. That's worth more than it initially sounds.

The irony works both ways though. You'll spend months obsessing over battery charging algorithms, then realise the actual problem was water ingress in a connector. Systems thinking only carries you so far.

The shepherds' hut taught me that more than anything. All the theory in the world doesn't prepare you for what happens when your power budget meets reality and loses.

Great thread this. I've got to say though—and I reckon @AndyRobinson and @DorsetDweller are dancing around it—there's a genuine gulf between managing systems and living with their limitations day-to-day.

I worked in electrical contracting for years before going off-grid, and what surprised me most wasn't the technical side (which, fair play, we all had sorted). It was the mindset shift. When you've got mains backup your whole career, you think in terms of "fix it when it breaks." Off-grid forces you to think preventatively—battery management, load management, seasonal variation. It's almost philosophical.

@IslandOffGrid, I'm curious whether your consultancy background actually made the transition easier or if you found yourself unlearning some stuff? I suspect there's a difference between designing renewable systems and living inside one's constraints.

@BurnWalker, your HVAC experience will be handy for thermal efficiency at least. Just don't expect your old troubleshooting habits to translate directly. Off-grid living's more about working with your system

Proper useful background that, @BurnWalker. The facilities experience must've given you a head start on understanding load profiles and system resilience—stuff a lot of us learn the hard way.

I came from solar installation work, which helped loads when I was spec'ing my own setup. But honestly, the real education happened after going off-grid. Theory versus reality are miles apart when you're managing your own battery bank at 2am in January, yeah?

The irony cuts both ways though—all that knowledge of centralised grid systems doesn't always translate neatly. Had to unlearn a fair bit about redundancy and oversizing. Off-grid forces you to think different: efficiency becomes an obsession, not an afterthought.

Reckon the best prep isn't necessarily the job itself, but whether you've spent time properly troubleshooting systems under pressure. That problem-solving mindset matters more than the specific domain.

What're you finding most relevant from the FM background now you're off-grid?
