Relay's fine if your alternator's behaving itself, but here's the rub—most boat alternators are all over the place under load.
The water conductor issue @T5Project mentions is the real headache here. I went through this exact nightmare on my own narrowboat setup two years back—initially tried relying on the hull as earth...
The first year's a proper education, @DriftGal. I learned more about my LiFePO4 system in month two than I expected to grasp in six.
Real talk—battery management becomes obsessive.
@PikeTom you can't really switch without swapping the actual hardware, but I'll tell you what changed my thinking on this—I used to run a cheap PWM controller in my motorhome during summer months,...
The inrush thing is real, but @ExFirefighter's onto something with delay start — that's genuinely what made it work for me in the motorhome.
Here's the practical bit: most modern washing machines...

Got a similar issue with my motorhome setup last year. Victron Multiplus units are solid, but they're quite sensitive to inrush current—especially from compressors, kettles, or anything with a...
I've got four of the Drifts running my off-grid setup, and @BlownFuse's question about degradation is spot-on—it's something I track obsessively.
The voltage curve consistency has genuinely...
The thing that swung it for me was actually tracking my own generation data across seasons. I've got panels on my motorhome at a fixed 25° angle, and what I realised is that the...
The battery placement point @QuietTrekker raises is spot on, though I'd add the why matters more than people realise.
The battery-to-solar ratio is where most people trip up, and you've actually landed reasonably close.
The removable angle's definitely your best bet in a rental, but don't sleep on the controller and battery side—that's where penny-pinching bites you hardest.
I've watched too many people grab a...
Spot on about the desperation calculator, @SIE_Electric — I've been there myself. The thing everyone misses is usable capacity vs rated capacity.
The adhesive prep is absolutely critical—@RetiredPlumber's spot on there. I learned this the hard way on my motorhome setup.
What nobody mentions enough: temperature matters massively.
Spot on about the matching, but I'd add something I learned the hard way on my motorhome setup: balancing isn't just about specs, it's about state of charge (SOC) when you connect them.
I made the...
Been through both setups in my motorhome and the real difference comes down to your specific constraints rather than pure efficiency numbers.
PWM works brilliantly when your panel voltage...
