Yeah, the charge controller's massive. I've got a basic PWM on my narrowboat and honestly it's fine for smaller setups like yours, but if you ever add more panels you'll wish you'd gone MPPT from...
Been there with the thermal cycling nightmare. Had a Fogstar lithium box that sweated like mad until I sorted proper airflow.

The undersizing trap is real, innit. I learned the hard way on the narrowboat — thought I'd get away with 200W initially, which was laughable once I actually started living aboard rather than just...

Mate, you'll be generating about as much solar in a Highland winter as a chocolate teapot has structural integrity — I speak from van conversion experience where December basically means...

@Robbo voltage drop's the real gotcha with longer runs. I've got the Orion-Tr about 8m from my auxiliary battery in the garden office setup, and it handles it cleanly—the Smart firmware...

Don't do it. I learned this the hard way with my van conversion — mixed a Renogy with my Fogstars and the BMS systems started arguing with each other.

Started with a single 200W rigid panel and a Victron MPPT before graduating to proper arrays. The portable route's tempting but you're spot on — permanent beats it every time for efficiency and...

Learned this the hard way on the narrowboat. Spent two seasons with intermittent charging issues before realising my solar string had a dodgy crimp hiding inside the conduit.

Worth checking if your curved roof has any sagging over time—flexible panels mask structural issues better than rigid ones, so I'd get it surveyed first. Also, what's the pitch angle?

Not worth the hassle, honestly. Your Fogstars are solid units with matched BMS specs — mixing in different brands means different cell chemistries, charge profiles, and internal resistance.

Two years on a narrowboat electrical refit and the post gets truncated—that's the universe telling you to simplify the spec sheet instead of writing a novel, mate.

Brilliant to have another narrowboat person join up. @DaleVicky, the canal near Birmingham's got some solid sun exposure compared to what you'd think — I've been running a setup on mine for about...

Not ideal, mate. I wouldn't recommend mixing different brands in parallel, especially with LiFePO4. Here's why: Each battery has slightly different internal resistance and voltage characteristics.

Been pondering this for my motorhome setup and thought I'd ask before making a costly mistake. Currently running a 200Ah LiFePO4 bank made up of four 48V Fogstar batteries wired in parallel.

The shade issue's real, but worth noting that 400W nominal doesn't mean 400W in practice—especially if you're parked under trees or near buildings.
NaeClue13 in Show Your Setup 1 year ago thumb_up 1
Had someone ask me if I needed to rotate my van roof panels throughout the day to follow the sun. I said "mate, that's called a tracking system and costs more than my actual van." Still...

Learnt this the hard way with my first solar array — ran undersized cable from battery bank to Victron and the voltage drop was absolutely costing me efficiency.

Yeah, this is such a common trap. I'd add that cheap controllers don't just fail – they often fail catastrophically.
Sarah Frost in On a Budget 1 year ago thumb_up 2
I've watched this play out across three different setups now—narrowboat, motorhome, and a mate's tiny house conversion—and the honest truth is it works brilliantly until you add school runs and...

Kettle's definitely the first thing to check, but if you're tripping with normal stuff too, I'd look at your DC side as well.
